在铸铁熔炼工作中,希望冲天炉能同时满足多方面要求,如较高的铁焦比,较高的出铁温度和较低的金属耗损等等。由于炉型结构、操作条件、工艺管理水平的差异,内在因素的相互制约,一种指标提高反而导致另一种指标降低。因此,目前对各种类型冲天炉的优劣,无法进行统一考核和比较。为改变这种状况。根据统计学原理,把冲天炉几个指标综合成一个可以相互比较的数值——选择指数。据此可以对各种炉子进行统一比较和选优工作。这不仅可以避免片面的追求铁焦比,忽略硅锰烧损影响铁水质量的倾向,而且还可以启发人们发现一些新的东西。
In cast iron smelting work, hope cupola can meet many requirements at the same time, such as higher iron coke ratio, higher iron temperature and lower metal loss and so on. Due to the furnace structure, operating conditions, differences in the level of process management, the internal factors of mutual restraint, an index increase but lead to another index lower. Therefore, the current advantages and disadvantages of various types of cupola, can not be a unified assessment and comparison. To change this situation. According to statistical principles, the cupola several indicators into one can be compared with each other numerical - choice index. According to which a variety of stoves can be a unified comparison and selection work. This not only avoids the one-sided pursuit of the iron-coke ratio, neglects the tendency of the loss of silicomanganese to affect the quality of molten iron, but also can inspire people to discover something new.
