Resistance Temperature of Refractory Castables

The temperature resistance of refractory castables depends on their material composition and preparation process. Generally speaking, refractory castables can withstand high temperatures, but the specific temperature range will vary depending on the type and formulation of refractory castables.

Some common refractory castables, such as high-aluminum refractory castables, corundum refractory castables, and low-cement refractory castables, have high-temperature resistance. These materials typically withstand high-temperature environments ranging from 1500°C to 1800°C.

However, for higher-temperature applications, such as steelmaking, glassmaking, or other high-temperature processes, specially formulated and prepared refractory castables may be required. These special refractory castables can withstand higher temperature tests, reaching or even exceeding 2000°C temperature resistance.

It should be noted that even if the refractory castable can withstand high temperatures, attention must be paid to the rate of temperature change and the temperature gradient to avoid rupture of the refractory castable or thermal shock due to rapid changes. Therefore, in practical applications, it is necessary to select appropriate refractory castables according to specific conditions and follow relevant usage instructions and operating specifications.
