Magnetation gets court approval to assume AK Steel offtake agreement

Magnetation LLC announced Wednesday that its subsidiary Mag Pellet LLC has been authorized by the United States Bankruptcy Court for the District of Minnesota to assume its long-term iron ore pellet offtake agreement with AK Steel Corporation.

The company sought Bankruptcy Court approval to assume the contract in October 2015. The Bankruptcy Court granted the company’s motion following a hearing on the matter earlier this month.

“This court decision is critical to Magnetation’s success” said Larry Lehtinen, CEO of Magnetation. “With this behind us, we can continue forward with our goal of being the lowest cost iron ore pellet producer in North America.”

The materials of gas tungsten arc welding

Gas tungsten arc welding is most commonly used to weld stainless steel and nonferrous materials, such as aluminum and magnesium, but it can be applied to nearly all metals, with a notable exception being zinc and its alloys. Its applications involving carbon steels are limited not because of process restrictions, but because of the existence of more economical steel welding techniques, such as gas metal arc welding and shielded metal arc welding. Furthermore, GTAW can be performed in a variety of other-than-flat positions, depending on the skill of the welder and the materials being welded.

For GTAW of carbon and stainless steels, the selection of a filler material is important to prevent excessive porosity. Oxides on the filler material and workpieces must be removed before welding to prevent contamination, and immediately prior to welding, alcohol or acetone should be used to clean the surface.[36] Preheating is generally not necessary for mild steels less than one inch thick, but low alloy steels may require preheating to slow the cooling process and prevent the formation of martensite in the heat-affected zone. Tool steels should also be preheated to prevent cracking in the heat-affected zone. Austenitic stainless steels do not require preheating, but martensitic and ferritic chromium stainless steels do. A DCEN power source is normally used, and thoriated electrodes, tapered to a sharp point, are recommended. Pure argon is used for thin workpieces, but helium can be introduced as thickness increases.

How do the quality of gas tungsten arc welding？

Gas tungsten arc welding, because it affords greater control over the weld area than other welding processes, can produce high-quality welds when performed by skilled operators. Maximum weld quality is assured by maintaining cleanliness—all equipment and materials used must be free from oil, moisture, dirt and other impurities, as these cause weld porosity and consequently a decrease in weld strength and quality. To remove oil and grease, alcohol or similar commercial solvents may be used, while a stainless steel wire brush or chemical process can remove oxides from the surfaces of metals like aluminum. Rust on steels can be removed by first grit blasting the surface and then using a wire brush to remove any embedded grit. These steps are especially important when negative polarity direct current is used, because such a power supply provides no cleaning during the welding process, unlike positive polarity direct current or alternating current. To maintain a clean weld pool during welding, the shielding gas flow should be sufficient and consistent so that the gas covers the weld and blocks impurities in the atmosphere. GTAW in windy or drafty environments increases the amount of shielding gas necessary to protect the weld, increasing the cost and making the process unpopular outdoors.

The level of heat input also affects weld quality. Low heat input, caused by low welding current or high welding speed, can limit penetration and cause the weld bead to lift away from the surface being welded. If there is too much heat input, however, the weld bead grows in width while the likelihood of excessive penetration and spatter increase. Additionally, if the welding torch is too far from the workpiece the shielding gas becomes ineffective, causing porosity within the weld. This results in a weld with pinholes, which is weaker than a typical weld.

If the amount of current used exceeds the capability of the electrode, tungsten inclusions in the weld may result. Known as tungsten spitting, this can be identified with radiography and can be prevented by changing the type of electrode or increasing the electrode diameter. In addition, if the electrode is not well protected by the gas shield or the operator accidentally allows it to contact the molten metal, it can become dirty or contaminated. This often causes the welding arc to become unstable, requiring that the electrode be ground with a diamond abrasive to remove the impurity.

The new motor vehicle registrations in Turkey has gone up

According to the statistics released by the Turkish Statistical Institute (TUIK), in October this year new motor vehicle registrations in Turkey decreased by 4.1 percent year on year to 84,903 units and were up by 1.1 percent on month-on-month basis. New passenger car registrations in October this year totaled 45,437 units, falling by 1.9 percent as compared to September and down 11.7 percent year on year. Passenger cars accounted for 53.5 percent of total new motor vehicle registrations in the given month. On the other hand, new small truck registrations in October increased by 5.47 percent month on month and were up 17.84 percent year on year, amounting to 14,413 units. Small truck registrations constituted 17 percent of total new registrations in October this year.

Shenzhen landslide events

A horrifying video of a landslide swallowing up the city of Shenzhen in southern China shows entire buildings being gobbled up in seconds. Meanwhile, the number of people missing has jumped to 91, China Central Television (CCTV) reports.

The disaster occurred in the Hengtaiyu industrial park in Shenzhen, Guangdong province, on Sunday morning, destroying a total of 22 buildings and causing a gas pipeline explosion. An area of about 1 million square meters has been buried in soil.

China’s Ministry of Land & Resources has blamed the disaster on a collapse of piled-up construction waste and soil residue in the area, state media said. It also cited a local emergency office giving a sharply increased estimate of the number of people missing. The figure had previously stood at 59.

Colleagues of the SEKO Machinery Company are talking about it, We are so sad to the affected people and their family members，everyone in mourning for Shenzhen.

CNC plasma cutting technology（2）

There are 3 main configurations of CNC Plasma Cutting, and they are largely differentiated by the forms of materials before processing, and the flexibility of the cutting head.

1、2 Dimensional / 2-Axis Plasma Cutting.

This is the most common and conventional form of CNC Plasma Cutting. Producing flat profiles, where the cut edges are at 90 Degrees to the material surface. High powered cnc plasma cutting beds are configured in this way, able to cut profiles from metal plate up to 150mm thick.

2、3 Dimensional / 3+ Axis Plasma Cutting.

Once again, a process for producing flat profiles from sheet or plate metal, however with the introduction of an additional axis of rotation, the cutting head of a CNC Plasma Cutting machine can tilt whilst being taken through a conventional 2 dimensional cutting path. The result of this is cut edges at an angle other than 90 Degrees to the material surface, for example 30-45 Degree angles. This angle is continuous throughout the thickness of the material. This is typically applied in situations where the profile being cut is to be used as part of a welded fabrication as the angled edge forms part of the weld preparation. When the weld preparation is applied during the cnc plasma cutting process, secondary operations such as grinding or machining can be avoided, reducing cost. The angular cutting capability of 3 Dimensional plasma cutting can also be used to create countersunk holes and chamfer edges of profiled holes.

3、Tube & Section Plasma Cutting.

Used in the processing of tube, pipe or any form of long section. The plasma cutting head usually remains stationary whilst the workpiece is fed through, and rotated around its longitudinal axis. There are some configurations where, as with 3 Dimensional Plasma Cutting, the cutting head can tilt and rotate. This allows angled cuts to be made through the thickness of the tube or section, commonly taken advantage of in the fabrication of process pipework where cut pipe can be provided with a weld preparation in place of a straight edge.
