影响球团带式焙烧机(OKM)工作热效应的因素有三类:热工的、工艺的和原料的,而工艺诸因素决定着OKM各带的加热速度、冷却速度,以及热加工的温度和时间。文中分析讨论的内容有:(1)球团内渗透气体的过程速度,即乾燥、加热、液固相烧结的过程速度是由料层内的热交换强度决定的。因此,含有的挥发物愈多,加热速度应该愈慢;精矿磨得愈细,乾燥速度应该愈慢;球团粒径 There are three types of thermal effects that affect the operation of the OKM Belt Roaster (OKM): thermal, process, and raw materials, and process factors determine the heating, cooling rate, and temperature and time of the hot strip . The content of analysis and discussion in this paper are as follows: (1) The process speed of gas permeation in the pellet, that is, the process of drying, heating and liquid-solid sintering is determined by the heat exchange intensity in the material layer. Therefore, the more volatiles it contains, the slower the heating rate; the finer the mill, the slower the drying rate should be; the size of the pellets
