Precast Block Compound Corundum Mullite Refractory Material for Industry Furnace Roof
The Description:
The prefabricated part is made into a certain shape according to the process parts and needs, and the heat treatment is carried out according to its working conditions after demoulding. Prefabricated parts have better application performance than castables.
Prefabricated parts can improve the performance of refractory lining, reduce the consumption of refractory materials, stable quality and reliable performance. Castable preforms made by special processes improve the mechanical properties of castables, inhibit the initiation of cracks or limit their propagation when they are formed.

The feature
(1) The compressive strength of the prefabricated parts is 2 times higher than that of the refractory castable.
(2) The thermal shock resistance of prefabricated parts is 2 to 3 times higher than that of castables.
(3) The wear resistance of prefabricated parts is 2 times better than that of castables of the same material.
(4) Save construction time: no need for on-site pouring, no need to support and disassemble molds, no need for construction machinery. The molded parts only need to be assembled on site, which is convenient and fast. The site construction time is greatly reduced, and the quality is stable, and it is not restricted by the site construction conditions and human factors.
(5) Save maintenance and baking time: at the time of delivery, the supplier has completed all aspects of pouring, maintenance, drying and baking in advance, saving a lot of maintenance and baking time, and effectively solving the problem of pouring material bursting caused by rapid ignition and heating on site.
