Xintai’s High Strength Precast Refractory Bricks are custom-engineered monolithic refractory blocks made from high-performance castables. These precast bricks are designed to offer superior mechanical strength, exceptional thermal resistance, and precise dimensional stability for demanding high-temperature industrial environments. Each unit is manufactured in a controlled environment and fired at high temperatures to ensure optimal performance and minimal shrinkage.
Ideal for areas exposed to extreme abrasion, thermal shock, and mechanical load, these bricks significantly reduce on-site installation time, minimize downtime, and extend the life of refractory linings.

Frequently Asked Questions (FAQ)
Q1: What’s the difference between precast refractory bricks and traditional refractory bricks?
Precast bricks are pre-formed blocks made from castable materials. Unlike shaped bricks made by pressing, precast units allow for complex designs and offer higher strength and installation efficiency.
Q2: Can you produce according to our drawings?
Yes. We specialize in custom-designed precast blocks based on your drawings or dimensions.
Q3. What is the average service life of precast refractory shapes?
It depends on the application and environment, but typically lasts longer than in-situ cast linings due to superior density and firing.
