摘要

本文介绍了磷酸盐原料热变形的实验研究结果，这对焙烧输送机和结块机热处理的化学和能源工艺过程的进展有重要影响。揭示了供加工用磷酸盐原料的化学和矿物组成对热变形值的影响。考虑加热速率，确定了加热过程中的热变形参数。研究发现，高温区域的热变形有助于磷酸盐材料的软化和熔化，从而导致烧结机输送机上的磷矿球团致密层或团聚机皮带上的烧结层中的负气体动力学过程

ANALYSIS OF TEMPERATURE-CONCENTRATION STABILITY OF THERMAL DEFORMATIONS OF PHOSPHORITES DURING HEATING

The work presents the results of experimental studies of thermal deformations of phosphate raw materials, which have a significant impact on the progress of chemical and energy technological processes of thermal treatment in roasting conveyor and agglomeration machines. Influence on the value of thermal deformations of chemical and mineralogical composition of phosphate raw materials supplied for processing was revealed. Parameters of thermal deformation during heating are determined taking into account heating rate. It has been found that thermal deformations in the region of high temperatures contribute to softening and melting of phosphate materials, thereby contributing to negative gas dynamics processes in the dense layer of phosphorite pellets on the sintering machine conveyor or in the sintering layer on the agglomeration machine belt
