AI Technical Summary
Existing converter smelting of high-phosphorus steel suffers from severe furnace lining erosion, large fluctuations in final phosphorus content, and high production costs.
By controlling the phosphorus capacity of the slag and adjusting the slag composition and operating parameters, including the amount of slag left, the oxygen content accumulated in the slag, the oxygen lance height and the oxygen supply intensity, the composition and reaction process of the slag are optimized, the proportion of high-melting-point RO phase in the slag is increased, the final phosphorus content is stably controlled, and the addition of ferrophosphorus is avoided.
It significantly increased the final phosphorus content of the converter, reduced production costs, improved product stability, and reduced environmental pollution.
