Recently, the anshan iron and steel by converter smelting process, successfully produced more than 3 mm thickness, width of 1100 mm, carbon content up to 0.9% of the 9 sicr hot rolled wide strip, composition and performance fully meet the requirements of the technical agreement after inspection, trial has now been sent to all users.

9 sicr is high carbon alloy tool steel, due to the high content of chromium and carbon, silicon, the steel hardenability, hardenability and good stability, tempering is often used in the manufacture of complex shape and small deformation demands, high wear resistance of low speed cutting cutting, cold work mould, etc. Currently widely used electric furnace smelting and rolling process of narrow-band 9 sicr rolled plate. Therefore, 9 sicr rolled plate on the market is generally not more than the width of 500 mm.

In order to meet market demand, expand the market sales, anshan iron and steel research institute and angang steel BaYuJuan branch, hand in hand with bof steelmaking process route, to overcome the high carbon steel smelting serious segregation and surface decarburization, mill load big, low volume classification equipment capability, a series of problems, successfully developed to produce more than 3 mm thickness, width of 1100 mm, carbon content up to 0.9% of the 9 sicr hot rolled wide strip.
