稳定炉内合理的煤气流分布是维持炉况顺行的重要方面。所谓“稳定煤气流”,首要的是维持稳定而足够的中心气流,在此条件下,才谈得上根据产量或节约燃料的要求,或者按照保护炉体设备的需要,对边缘气流加以适当的调整控制。另外,炉缸工作是高炉冶炼的基础,神户公司的试验证明,从炉喉中心装入少量焦炭,对于调整和稳定中心气流、改善炉芯的透液性和透气性,从而活跃炉缸有明显的效果。国内呈中心型气流分布的高炉尚少,因此,在现有装料设备和原料条件下,如能实施中心焦炭装入法,想必会给国内高炉生产带来较大的改观。
Stable furnace reasonable gas flow distribution is an important aspect of maintaining furnace conditions. The so-called “steady flow of gas” first and foremost is to maintain a steady and sufficient central gas flow, under which conditions it is appropriate to justify the marginal gas flow in terms of production or fuel saving requirements or to protect the equipment of the furnace Adjust control. In addition, the hearth work is the basis of blast furnace smelting, Kobe company’s test proved that a small amount of coke from the throat into the center for adjusting and stabilizing the center of the air flow to improve the liquid permeability and permeability of the hearth, which active hearth obvious Effect. Domestic blast furnace with central airflow distribution is still scarce. Therefore, under the conditions of existing charging equipment and raw materials, if central coke loading method is implemented, it is bound to bring great changes to domestic blast furnace production.
