Abstract

It was established that the completion degree of the processes that accompany the iron ore pellets annealing on conveyor machines depends largely on the layer’s internal heat source distribution over separate zones. And the most significant role is played by the magnetite oxidation and carbonate dissociation. During the industrial research conducted on one of the Kachkanarsk’s mining and processing plant (KMPP) conveyor machines, the influence of the original batch composition on the thermal technical indicators of the machine was studied. The consistent pattern obtained for the heat source distribution in the pellet layer along the annealing conveyor machine allows one to optimize separate zone sizes, thermal parameters of the pellets annealing and to find the heat share from the external source for optimal fuel consumption.

考虑层物理化学过程运行的输送机铁矿石球团退火工艺优化

摘要

已经确定，伴随在输送机上进行铁矿石球团退火的过程的完成程度很大程度上取决于层在不同区域上的内部热源分布。最重要的作用是磁铁矿的氧化和碳酸盐的分解。在对Kachkanarsk的一台采矿和加工厂（KMPP）输送机进行的工业研究中，研究了原始批料组成对该机器的热技术指标的影响。对于沿退火输送机在颗粒层中的热源分布所获得的一致模式，可以优化单独的区域大小，颗粒退火的热参数，并从外部源中找到热量共享，以实现最佳燃料消耗。
