How long do Plastic castable typically last before needing to be replaced?
The lifespan of plastic castables can vary depending on the application and operating conditions, but in general: For low to moderate temperature applications under 1200°F/650°C, plastic castables should last 5-10 years before needing replacement. At maximum continuous use temperatures of 1200-1400°F/650-760°C, lifespan is typically 3-5 years. In intermittent or cyclic high heat applications reaching 1400-1600°F/760-870°C,…
