一种布料方式在加热炉上的应用
|
摘要
研究了一种新型布料方式在二高线加热炉上的应用,主要针对小规格品种钢生产时燃耗高以及成本无法控制的问题,研究通过改变布料方式,达到减少煤气消耗的目的。结果表明:使用新的布料方式后,在生产6.0以下小规格品种钢,煤气消耗有大幅度下降。原生产5.5 mm品种钢的煤气单耗折算成转炉煤气366.23 m~3/t,改造后生产5.5 mm品种钢,煤气单耗折算成转炉煤气338.04 m~3/t,改造后煤气可节省28.19 m~3/t。
The application of one new kind charging method on the heating line of the second-highest line was studied. Aiming at the problem of high fuel consumption and uncontrollable cost, the purpose of reducing gas consumption is studied by changing the charging method. The results show that the use of new charging method resulted in significant drop in gas consumption in the production of small-sized steels of6.0 or less. The unit gas consumption of the original 5.5 mm type steel is converted to 366.23 m~3/t of converter gas, 5.5 mm steel is produced using a new type of structure, and the unit gas consumption is converted into converter gas 338.04 m~3/t. After the transformation, the gas can save 28.19 m~3/t.
