AI Technical Summary
Technical Problem
Existing technologies make it difficult to accurately control the chromium content in high-carbon steel wire rods, resulting in insufficient wire strength and complex control of chromium chemical reactions.
Method used
By controlling the reduction reaction of chromium and combining converter smelting, LF refining, continuous casting, continuous rolling and wire rod cooling processes, the chromium content is controlled to be below 0.01% to prevent chromium from entering the molten steel and to meet the quality requirements of high carbon steel wire rod.
Benefits of technology
Precise control of the chromium content in high-carbon steel wire rods has been achieved, ensuring that the wire strength meets the requirements and reducing the wire breakage rate and scrap rate.
