高炉下部中心焦炭层的透气性和透液性对高炉操作状况和炉体寿命影响很大,而且透气性和透液性过去是不能控制的。最近,神户钢铁公司成功的开发了高炉中心控制方法。该方法是从炉喉中心部位的极狭小区域,单独装入少量(总量的1％以下)的充填高炉中心料柱用的焦炭。这样,便可任意控
The permeability and liquid permeability of the coke layer in the lower center of the blast furnace have a great influence on the operating conditions of the blast furnace and the life of the furnace, and the air permeability and liquid permeability have not been controlled in the past. Recently, Kobe Steel successfully developed a blast furnace center control method. This method is to separately charge a small amount (less than 1% of the total amount) of coke used to fill the blast furnace center column from a very narrow area at the center of the throat. In this way, it can be controlled at will
