Thermophysical characteristics of refractory composite materials for glass production

When the lining of large refractory products is brought to the operating mode, it is important to know the temperature rise of the material in order to determine the mounting clearances and to be sure that during service with an increase in the temperature gradient along the thickness of the product, destruction will not occur due to structural transformations. At the Semiluksk Refractory Plant, comparative studies of the thermophysical properties of traditional fired fireclay materials (rammed bar for the bottom of the melt bath, semi-dry pressing bar ShSU) and low-cement concrete materials on fireclay aggregate grade VShS were carried out. In the service temperature range of 600 - 1300 ° C, the materials VShBS and VShBO showed a smooth insignificant change in TCLE with increasing temperature. Tab. 1, ill. 3, bibliography: 2 titles.
