Experimental and Numerical Study on Cooling Process of Sinter

Abstract

By means of thermal analysis, specific heat values of sinter with different temperatures are measured and the linear function which along with the change of temperature is got. According to the actual condition, the porous medium model which describes the cooling process is established. The influences on cooling process of specific heat with fixed and variational values are compared. With the variational specific heat, the effects on cooling process of sinter initial temperature and air temperature are discussed. The result shows that both increasing sinter initial temperature and cold air temperature can improve the exhaust heat utilization, but the later delay the cooling time.
