Abstract—One of the most important thermophysical characteristics of pellets, namely, their heat capacity, which affects the production of iron-ore pellets at the stage of their heat treatment in a layer on the belt of a horizontal-grate machine, is considered. Since the physical heat capacity of a material is determined by enthalpy, the mixing method is used to measure the latter on a setup with an adiabatic calorimeter. The object of research is represented by Kachkanar pellets of various basicities. The average enthalpy of pellets and their physical heat capacity are presented in the form of interpolation equations with allowance for changes in the phase and chemical composition of the material. The temperature dependences of the apparent heat capacities of pellets of various basicities at various heating rates are determined using a newly created experimental installation, which allows a set of thermophysical characteristics to be determined. Quantitative thermal analysis is applied to estimate the enthalpy change and the temperature dependence of the apparent heat capacity for the nonfluxed and fluxed concentrates of the Sokolov–Sarybay Mining Production Association using the created experimental installation. The techniques used to determine the enthalpy and the heat capacity of iron-ore pellets and concentrates and the constructions created for the implementation of these techniques can be applied to determine the heat capacities of various materials of metallurgical production and to optimize the operating parameters of their heat treatment.

摘要：球团矿最重要的热物理特性之一，即热容量，在水平炉排机带上的一层热处理阶段，会影响铁矿球团矿的生产。由于材料的物理热容是由焓决定的，因此使用混合方法在绝热热量计的装置上测量后者。研究对象以各种碱度的 Kachkanar 颗粒为代表。颗粒的平均焓及其物理热容以插值方程的形式呈现，并考虑到材料的相和化学成分的变化。使用新创建的实验装置确定了不同加热速率下不同碱度颗粒的表观热容的温度依赖性，该装置可以确定一组热物理特性。使用所创建的实验装置，采用定量热分析来估计索科洛夫-萨里贝矿业生产协会的非助熔剂和助熔剂精矿的焓变和表观热容的温度依赖性。用于确定铁矿石球团和精矿的热函和热容的技术以及为实施这些技术而创建的结构可用于确定冶金生产中各种材料的热容并优化其操作参数。热处理。
