在钢铁工业中,高炉炼铁工艺在今后相当长的时期内仍将占主导地位。尽管高炉炼铁的焦比一直在下降,但焦炭的需求量仍呈上升趋势。在焦炭生产中,若不能很好地解决环保问题,再加上焦炉的投资和生产费用日渐提高,必然会导致世界范围内出现焦炭供不应求的局面。这就向炼焦工业提出了 In the iron and steel industry, the blast furnace ironmaking process will continue to dominate for a long time to come. Although the coke ratio of blast furnace ironmaking has been decreasing, the demand for coke is still on the rise. In the production of coke, if the problem of environmental protection cannot be properly solved, coupled with the increasing cost of investment and production of coke ovens, it will inevitably lead to a situation in which coke is in short supply. This proposed to the coking industry
