Baosteel Special Steel steelworks 40 tons production line with production capacity of high carbon chromium bearing steel

 Recently, Baosteel Special Steel Division steelworks 40 tons production line has produced three batches of pilot carbon chromium bearing steel, the NSK company checks certification, its large-scale control of all non-metallic inclusions reach A level standard, internal quality indicators meet user requirements, marking the production line capable of producing high-carbon chromium bearing steel capacity.
NSK Corporation is Special Steel Division bearing steel supplied key users. The company mainly produces high-end products bearing the carbon chromium bearing steel internal quality control is very strict, the original 100 tons electric furnace steel mill bearing steel professional production furnace base, after the 40 tons production line to assume the high-carbon chromium bearing steel production responsibilities.
To ensure high-carbon chromium backing bearings ertified material in the production of 40 tons production line smoothly, steel mills set up by a biotech room, two refining factory technical personnel involved in quality improvement group bearing steel, and manufactured with the Ministry of professionals to carry out subject research activities. They were on the original 100 t EAF process for adjustments, process and process parameters in terms of the repeated demonstration, using a steel furnace conditions improve, control alkalinity refining new ways to ensure refining vacuum treatment effect.
At present, a total of nine batches completed furnace carbon chromium bearing steel certified materials are acceptable to users.
