steel mills set up by a biotech room

NSK Corporation is Special Steel Division Taper 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 bearing steel certified 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 tapered 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.
