* Book * bubble bar ( ) name called Jiangnan steelworks. Sung now held by the director. Sung and also his own laboratory moved here. At this time had built nike free run a five blast furnaces and two steel cupola. Emergence of Modern smelting technology is divided into two steelmaking furnace steelmaking Peace Law,nike air max 90, the former single simple process, tapping fast, but the quality can not be guaranteed Chenggang, good and bad, and that can not be recycled scrap. The latter is good quality steel refining, raw material requirements are not high, scrap can be re-used, but the process is more complicated.
Want refining high-quality steel,nike air max 95, Guan Jian is that temperature, the higher the temperature generated by refining the steel quality is mulberry outlet higher. So whether steelmaking method, however, is still open hearth steelmaking process must preclude the use of regenerative cell technology, which is to replace the hot blast of cold blast. Of course, that is not regenerative furnace, you can iron or steel, but in the productivity and the quality can not be compared completely. According to calculations, the early regenerative furnace, if air can be increased to more than three degrees, then the same amount of fuel under conditions of iron production will increase threefold over the cold blast.
Regenerator technology produced in the nineteenth century, in fact, cast iron in blast pipe manifold air through a sealed with a very thick brick and masonry arch furnace refractories, and then re-entering the cupola of the air. Thus, the drum to wind in the cupola will be directly heated, the temperature can be increased to three or more Baidu, Baidu can be up to about five. Thus greatly improving smelting iron steelmaking temperatures. Now the two cupola work also varies, one cupola in refining molten iron flows directly out of the steelmaking furnace, and then after further refining, Tempered steel products, and the other in the cupola is a part of the cooling molten iron into iron anchor for Arsenal to use a part of the direct pour into iron ROBOT, a system to its nike air max 2014 finished.
