在炼钢成本当中,钢铁料消耗占炼钢成本80%以上,而转炉冶炼过程的吹损在总的钢铁料中仍占有80%以上。因此,降低转炉吹损是降低炼钢工序生产成本的重中之重,本文通过八钢转炉生产实践,对影响转炉吹损的主要因素进行分析,探索降低转炉吹损的途径。 Steelmaking costs account for more than 80% of steelmaking costs, while blowing losses in converter smelting still account for more than 80% of the total steel stock. Therefore, reducing converter blow-down is the most important factor to reduce the production cost of steel-making process. In this paper, the main factors that affect converter blow-down are analyzed and the ways to reduce converter blow-down are explored.
