Description:
SIJIHUO REFRACTORY produces a comprehensive range of fire clay brick with 45-55% Alumina content, all of which exhibit excellent compressive strength. For more arduous environments Typically our firebrick range is based upon flint clay giving it both a low iron and low alkali characteristic. Resistance to thermal shock, abrasion, chemical attack and reducing atmospheres are just some of the key criteria determining choice of product within each application. Various of sizes are available in our refractory material warehouse.
Features:
Fireclay brick has low thermal conductivity, good thermal insulation performance compared with high alumina refractory brick. SIJIHUO REFRACTORY produce fireclay bricks whick with long service life, easy operation, and special shapes are available if customers can provide drawings.
Among all of the refractory materials, it is the most widely used, and with cheaper price.
Applications:
1. Carbon bake furnaces in the aluminum industry
2. Preheat zones and cyclones of rotary cement kilns
3. Insulation for glass tanks
4. Fireplace and pizza ovens
5. Coke ovens
6. Blast furnaces
7. Reheating furnaces
8. Suspended roofs
