Rotary kilnWikipedia
A typical refractory will be capable of maintaining a temperature drop of 1000 °C or more between its hot and cold faces The shell temperature needs to be maintained below around 350 °C to protect the steel from damage and continuous infrared scanners are used to give early warning of hot spots indicative of refractory failure.

Jan 01 1982 This refractory made by calcining the natural mineral CaMg CO 3 2 consists essentially of a mixture of lime and magnesia As lime has much less resistance to attack by iron oxide the durability of dolomite in say the bottom of an open hearth furnace is appreciably less than that of magnesia but not by so much as simple theory would suggest.
