Web2. feb 2024 · Refractory linings are designed to maintain physical properties at very high temperatures – 932°F and above. Refractories used to line thermal equipment must have proper insulating properties to reduce the steel skin temperatures to acceptable levels, usually well below 300°F. Web11. apr 2024 · Back-Up Lining. RENO GN 25 LW – offers a thermally efficient lining, as a backup or working lining, by reducing heat loss and heat storage. It guns well and has little rebound. The insulation helps keep the steel shell cooler and has less expansion, which reduces cracking as the anchors are attached to the steel.
Webrefractories. Apart from heat resistance, these refractories should also possess a thermo-mechanical property called refractoriness under load The thermal properties that are of important are heat capacity, thermal expansion, and thermal conductivity. Heat capacity is a measure of the heat required for changing the temperature.
