Refractory brick|Magnesium carbon brick raw material selection impact on product performance|

After the first successful research in Japan, the magnesia carbon brick was first used in the hot spot of the high and ultra high power electric furnace and the air supply nozzle of the bottom blowing converter. In the future, Japan used magnesia carbon bricks in various parts of the converter. The life of the converter is increased by about 1.3 to 1.6 times compared with the magnesium dolomite brick immersed in tar.

Damage of 180t converter lining in a factory

The top-bottom combined blown converter is currently the most widely used steelmaking equipment in the world, and the length of the lining life directly affects the converter operation rate and production cost of the steel mill. In recent years, with the development of converter steelmaking towards high-strength, large-scale and smelting high-quality steel grades, higher requirements have been placed on furnace-lined refractories.

Selection of Roller Material for Bar Continuous Rolling Mill and Analysis of High Speed Steel Roll in Finished Rack

Foreword: In order to meet the needs of the next work, it is necessary to carry out the analysis of the roll of the bar mill. This needs to analyze the characteristics of the precision frame, better analyze the performance characteristics of the frame roll, and systematically expound. Better analysis of material modules, application modules, etc., to ensure the improvement of its overall quality, to achieve its overall performance improvement, better meet the needs of the current work module.

Process characteristics of CPC high speed steel roll

In order to overcome the segregation defect of high-speed steel roll in centrifugal casting, Nippon Steel Co., Ltd. developed the c-matching method (continuous casting outer layer forming method) for manufacturing high-speed steel roll. 1 it has the characteristics of energy saving and good roll performance. Its basic principle is to cast the molten steel as…
