STUDYING OF THERMOPHYSICAL PROPERTIES OF CARBONATE SIDERITE ORE AND AGGLOMERATES ON ITS BASIS

By using the method of mixing the dependence of changing of enthalpy of specimen of siderite ore and agglomerates on temperature was found. The interpolational equations were formed on the basis of the received data, they represent that dependence for enthalpy, original and average heat capacity in broad interval of temperatures. The possibility of application of the method of additive calculation for determination of heat capacity and enthalpy of agglomerates and ore with sufficient exactness for engineering practice was defined. According to the results of measuring heat capacity, density and coefficient of temperature conductivity, the dependence of the coefficient of temperature conductivity of siderite ore on temperature was defined. The received data permit forming the thermal balances of separate zones of shaft-furnace for roasting siderite ore and basing the optimum value of the consumption of solid fuel at agglomeration and also optimizing constructive and operating parameters of the work of thermal aggregates designed for heat treatment of siderite ore and receiving agglomerates.
