Answer: Fine material principle to reduce the amount of slag. Reasonable slagging system. Reasonable oxygen supply system, loading system to reduce mechanical spattering. Thermal compensation technology, consume more scrap to reduce chemical burn loss. Reasonable re-blowing technology.
Cold-rolled sheets have good surface quality, high dimensional accuracy and no oxide sheet due to rolled at room temperature. After annealing treatment, its mechanical properties and technological properties are better than hot-rolled sheet, mostly used of automotive, electrical products, locomotives, aviation, precision instruments, food and other industries. In the planning and design…
1Cr17Mn6Ni5N stainless steel is instead of grade 1Cr17Ni7, it is with magnetic properties after cold rolled, used for railroad cars. 1Cr17Ni7 stainless steel has high strength after cold working for railroad cars, conveyor belts, bolts and nuts. 1Cr18Ni9 stainless steel has high strength after cold working, but the elongation is…
