前言众所周知,在影响化铁炉熔炼好坏的诸因素中,“风”是最灵敏、最经济和最有效的可调因素。风少了不行,多了也不好,在一定的炭耗量条件下,应有个相适应的供风量(即风炭平衡)。在焦炭质量一般的条件下,凡是做到了风炭平衡的炉子一般都可实现高温、低硫和低焦耗的目标。但我国炼钢化铁炉随着熔化带直径的扩大,矮胖形的出现原风机已经不相适应了,供风强度仅40～80米~3/米~2分,炉前风压120～250毫米汞柱。这很难实现风炭
Preface As we all know, in the factors that affect the quality of smelting furnace, “wind” is the most sensitive, most economical and most effective adjustable factors. Wind less not, more is not good, in a certain amount of carbon consumption conditions, there should be a suitable supply of air (ie, wind and carbon balance). In the coke quality under normal conditions, all those who have achieved a balance of carbon stove can generally achieve high temperature, low sulfur and low coke consumption goals. However, with the enlargement of the melting zone diameter, China’s iron and steel making furnaces have become incompatible with the emergence of the short, fat-shaped fan. The wind strength is only 40-80 m 3 / m 2, 250 mmHg. This is difficult to achieve charcoal
