高炉炼铁过程是在炉料与煤气和向运动中进行的。必须始终保持炉料及煤气两大流股均衡、稳定地运动与合理分布,才能确保高炉过程稳定顺行。认识高炉内料运动的基本状况,掌锅炉料下降速度及其影响因素,对于能动地控制过程,使高炉高产、优质、低耗,无疑是十分重要的。 Blast furnace ironmaking process is carried out in the charge and gas and to the movement. We must always maintain the balance of charge and gas flow, stable movement and reasonable distribution, in order to ensure stable and smooth blast furnace process. It is undoubtedly important to know the basic situation of material movement in the blast furnace and the descending speed of the pallet charge and its influencing factors so as to control the process actively and make the blast furnace with high yield, high quality and low consumption.
