EUROFER Outlook for exports remains uncertain for 2016 and 2017

Seko Machinery Company manager Mr Xiao Yuanping said, ”We should strengthen our understanding of international market conditions in order to make correct judgments regarding the steel market trend and then to get more sales of ourwelded pipe making machine.”

Total steel exports from the EU to third countries fell 13 percent year on year in the third quarter of 2015, having seen a much more moderate three percent decline in the second quarter, according to the Economic and Steel Market Outlook 2016-2017/Q1 2016 Report from the Economic Committee of the European Steel Association (EUROFER). EUROFER said that over the first 11 months of 2015 total exports slipped by nine percent year on year, due to a 28 percent drop in exports of semi-finished products, a seven percent reduction in exports of flat products and a three percent fall in exports of long products. With regard to the key destinations for EU exports, Turkey and the US accounted for almost 50 percent of flat product exports. The most important destination for long products remained the Algerian market, which absorbed 40 percent of total EU long product exports. Switzerland, the US and Turkey are among the other major markets for long products. According to EUROFER, the outlook for EU steel exports in 2016 and 2017 remains rather uncertain. International competition looks set to remain fierce as long as several major emerging markets face economic headwinds and as a consequence will see pressure on steel demand.

What is the effect of rust on the economy？

Rust is associated with degradation of iron-based tools and structures. As rust has a much higher volume than the originating mass of iron, its build-up can also cause failure by forcing apart adjacent parts — a phenomenon sometimes known as "rust packing". It was the cause of the collapse of the Mianus river bridge in 1983, when the bearings rusted internally and pushed one corner of the road slab off its support. Seko Machinery Company‘s Stainless Steel pipe making machine production of welded pipe will not rust.

Rust was an important factor in the Silver Bridge disaster of 1967 in West Virginia, when a steel suspension bridge collapsed in less than a minute, killing 46 drivers and passengers on the bridge at the time. The Kinzua Bridge in Pennsylvania was blown down by a tornado in 2003, largely because the central base bolts holding the structure to the ground had rusted away, leaving the bridge anchored by gravity alone.

Reinforced concrete is also vulnerable to rust damage. Internal pressure caused by expanding corrosion of concrete-covered steel and iron can cause the concrete to spall, creating severe structural problems. It is one of the most common failure modes of reinforced concrete bridges and buildings.

The prevention of rust technologies（3）——Coatings and painting

Rust formation can be controlled with coatings, such as paint, lacquer, or varnish that isolate the iron from the environment. Seko Machinery Company’s Welded pipe making machine to produce the welded pipe can be painted to rust. Large structures with enclosed box sections, such as ships and modern automobiles, often have a wax-based product (technically a "slushing oil") injected into these sections. Such treatments usually also contain rust inhibitors. Covering steel with concrete can provide some protection to steel because of the alkaline pH environment at the steel-concrete interface. However rusting of steel in concrete can still be a problem, as expanding rust can fracture or slowly "explode" concrete from within.

As a closely related example, iron bars were used to reinforce stonework of the Parthenon in Athens, Greece, but caused extensive damage by rusting, swelling, and shattering the marble components of the building.

When only temporary protection is needed for storage or transport, a thin layer of oil, grease, or a special mixture such as Cosmoline can be applied to an iron surface. Such treatments are extensively used when "mothballing" a steel ship, automobile, or other equipment for long-term storage.

Special anti-seize lubricant mixtures are available, and are applied to metallic threads and other precision machined surfaces to protect them from rust. These compounds usually contain grease mixed with copper, zinc, or aluminum powder, and other proprietary ingredients.

The prevention of rust technologies（2）——Galvanization

Galvanization consists of an application on the object to be protected of a layer of metallic zinc by either hot-dip galvanizing or electroplating. Zinc is traditionally used because it is cheap, adheres well to steel, and provides cathodic protection to the steel surface in case of damage of the zinc layer. In more corrosive environments (such as salt water), cadmium plating is preferred. Galvanization often fails at seams, holes, and joints where there are gaps in the coating. In these cases, the coating still provides some partial cathodic protection to iron, by acting as a galvanic anode and corroding itself instead of the underlying protected metal. The protective zinc layer is consumed by this action, and thus galvanization provides protection only for a limited period of time.

More modern coatings add aluminium to the coating as zinc-alume; aluminium will migrate to cover scratches and thus provide protection for a longer period. These approaches rely on the aluminium and zinc oxides re-protecting a once-scratched surface, rather than oxidizing as a sacrificial anode as in traditional galvanized coatings. In some cases, such as very aggressive environments or long design life, both zinc and a coating are applied to provide enhanced corrosion protection. Seko Machinery’s Decorative pipe making machine can produce galvanized iron pipe.

Typical galvanization of steel products which are to subject to normal day to day weathering in an outside environment consists of a hot dipped 85 µm zinc coating. Under normal weather conditions, this will deteriorate at a rate of 1 µm per year, giving approximately 85 years of protection.

The prevention of rust technologies（1）——Rust-resistant alloys

Because of the widespread use and importance of iron and steel products, the prevention or slowing of rust is the basis of major economic activities in a number of specialized technologies.

Rust is permeable to air and water, therefore the interior metallic iron beneath a rust layer continues to corrode. Rust prevention thus requires coatings that preclude rust formation.

Rust-resistant alloys

Stainless steel forms a passivation layer of chromium(III) oxide. Similar passivation behavior occurs with magnesium, titanium, zinc, zinc oxides, aluminium, polyaniline, and other electroactive conductive polymers. Seko Machinery Company sells the Rust-resistant alloys pipe making machine, welcome to contact with Lucy Xie(Email:sevvice@gdseko.com).

Special "weathering steel" alloys such as Cor-Ten rust at a much slower rate than normal, because the rust adheres to the surface of the metal in a protective layer. Designs using this material must include measures that avoid worst-case exposures, since the material still continues to rust slowly even under near-ideal conditions.

Annealing setup and equipment

Typically, large ovens are used for the annealing process. The inside of the oven is large enough to place the work piece in a position to receive maximum exposure to the circulating heated air. For high volume process annealing, gas fired conveyor furnaces are often used. For large workpieces or high quantity parts, car-bottom furnaces are used so workers can easily move the parts in and out. Once the annealing process is successfully completed, work pieces are sometimes left in the oven so the parts cool in a controllable way. While some work pieces are left in the oven to cool in a controlled fashion, other materials and alloys are removed from the oven. Once removed from the oven, the workpieces are often quickly cooled off in a process known as quench hardening. Typical methods of quench hardening materials involve media such as air, water, oil, or salt. Salt is used as a medium for quenching usually in the form of brine (salt water). Brine provides faster cooling rates than water. This is because when an object is quenched in water air bubbles form on the surface of the object reducing the surface area the water is in contact with. The salt in the brine reduces the formation of air bubbles on the object's surface, meaning there is a larger surface area of the object in contact with the water, providing faster cooling rates. Quench hardening is generally applicable to some ferrous alloys, but not copper alloys. The working principle of the Seko Machinery’s Bright annealing machine and Black annealing machine are like that.

MMK ports net profit for 2015

Russian steel producer Magnitogorsk Iron and Steel Works (MMK) has announced its financial results for the fourth quarter and the full year of 2015 according to International Financial Reporting Standards (IFRS). In the fourth quarter, MMK registered a net loss of $125 million, compared to a net profit of $78 million in the third quarter of the year, while the company’s revenues decreased by 21.4 percent quarter on quarter to $1.18 billion, primarily due to the seasonal decline in domestic sales and a decrease in the average steel price during the quarter. In the fourth quarter, MMK’s EBITDA decreased by 36 percent to $275 million, with the EBITDA margin declining from 28.6 percent in the third quarter to 23.3 percent. Meanwhile, in 2015 the company recorded a net profit of $421 million compared to a net loss of $44 million in 2014, while its revenues decreased by 26.6 percent year on to $5.8 billion. The decline in revenue was primarily driven by lower sales volumes (down eight percent year on year) due to a decline in domestic demand for steel (down 12 percent year on year) and an increase in intra-group turnover. In the same year, MMK’s EBITDA increased by 3.8 percent year on year to $1.66 billion, with the EBITDA margin rising from 20.2 percent in 2014 to 28.6 percent.

According to MMK, in 2016 the Russian metals industry will remain under pressure from low capacity utilization globally, an increase in exports from China, growing protectionism in export markets and weak domestic demand. “China and Russia are neighbors, and the influence of the news for us is too big.” The manager of the Seko Machinery(Is a specialized manufacture INOX Pipe Making Machine company), Mr. Shaw said.

Waht is the resistive heating？

       Resistive heating can be used to efficiently anneal copper wire; the heating system employs a controlled electrical short circuit. It can be advantageous because it does not require a temperature-regulated furnace like other methods of annealing. Seko Machinery Company's Annealing Equipment is use the resistive heating.

The process consists of two conductive pulleys (step pulleys), which the wire passes across after it is drawn. The two pulleys have an electrical potential across them, which causes the wire to form a short circuit. The Joule effect causes the temperature of the wire to rise to approximately 400 °C. This temperature is affected by the rotational speed of the pulleys, the ambient temperature, and the voltage applied. Where t is the temperature of the wire, K is a constant, V is the voltage applied, r is the number of rotations of the pulleys per minute, and ta is the ambient temperature:

The constant K depends on the diameter of the pulleys and the resistivity of the copper.

Purely in terms of the temperature of the copper wire, an increase in the speed of the wire through the pulley system has the same effect as an increase in resistance. Therefore, the speed of the wire can be varied quadratically as the voltage is applied.

What is the full anneal？

A full anneal typically results in the second most ductile state a metal can assume for metal alloy. Its purpose is to originate a uniform and stable microstructure that most closely resembles the metal's phase diagram equilibrium microstructure, thus letting the metal attain relatively low levels of hardness, yield strength and ultimate strength with high plasticity and toughness. To perform a full anneal on a steel for example, steel is heated to slightly above the austenitic temperature and held for sufficient time to allow the material to fully form austenite or austenite-cementite grain structure. The material is then allowed to cool very slowly so that the equilibrium microstructure is obtained. In most cases this means the material is allowed to furnace cool (the furnace is turned off and the steel is let cool down inside) but in some cases it's air cooled. The cooling rate of the steel has to be

sufficiently slow so as to not let the austenite transform into bainite or martensite, but rather have it completely transform to pearlite and ferrite or cementite. This means that steels that are very hardenable (i.e. tend to form martensite under moderately low cooling rates) have to be furnace cooled. The details of the process depend on the type of metal and the precise alloy involved. In any case the result is a more ductile material but a lower yield strength and a lower tensile strength. This process is also called LP annealing for lamellar pearlite in the steel industry as opposed to a process anneal, which does not specify a microstructure and only has the goal of softening the material. Often the material to be machined is annealed, and then subject to further heat treatment to achieve the final desired properties.
