Kametstal has recently announced an expansion in the range of steel that can be smelted using cost-effective technology with preheating of scrap, as per the company’s press release on Facebook. The innovative preheated smelting technology involves heating scrap with oxygen and gas coal immediately after it’s poured into the converter, before liquid iron is added. This allows for increased use of scrap metal, reducing the consumption of liquid iron in steel production and lowering its cost.
The development and implementation of this efficient technology in the BOF Shop required significant effort and expertise. Parameters for melting, amount of oxygen and gas coal for heating, optimal scrap heating modes, prevention of liquid phase formation during pig iron pouring, and melting blowing modes were all carefully selected. The technology has proven its economic efficiency in meeting parameters and quality requirements for steel produced in the converter.
Kametstal continues to innovate by increasing the share of melts with scrap preheating and reducing the consumption of liquid iron in steelmaking. In addition to this advancement, Kametstal has expanded the range of longitudinal shaped sections at the rolling mill’s pipe billet mill. The production of a new profitable steel product, a round section with a diameter of 27 mm, has also been mastered at the 400/200 mill.
