实验室试验研究表明,在适当条件下用混装冶炼代替层装冶炼,可以降低高炉块状带的压差.高炉所用料批越大,混装效果越明显,且在入炉焦炭量波动的情况下,仍可维持顺行。另外,入炉烧结矿的含粉量越大,混装比层装更具有较好的透气性(但这并不是说混装可忽视原料的质量).同时,通过炉料结构的变化,可以做到用混装来调剂混装,以适应不同的炉况需要。 Laboratory tests show that, under appropriate conditions, mixed smelting instead of stratified smelting can reduce the pressure difference of the blast furnace block.When the blast furnace material batch is larger, the mixing effect is more obvious, and when the amount of coke in the furnace fluctuates The case can still be maintained. In addition, the larger the amount of dust contained in the sinter, the better the breathability (but this is not to say that mixing can neglect the quality of the raw material), and the structure of the charge can be changed Mixing to adjust the mix to meet the needs of different furnace conditions.
