We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of fire clay bricks
Fire clay bricks are rich in raw materials and are more widely used than any other refractories. It is mainly used in blast furnace, hot blast furnace, cupola, steel ladle and pouring system, soaking pit, heating furnace, nonferrous metal smelting furnace, silicate industry and chemical industry kilns, and chimneys and flues of all thermal equipment.

Details of fire clay bricks
On the basis of the production of ordinary clay bricks, the clay bricks produced by our company use good homogenizing materials as the main raw materials, add appropriate auxiliary materials and some additives, after fine grinding, mixing, high-pressure molding, and transform into mullite crystal phase at an appropriate firing temperature, so that the products have good mineral composition, so as to ensure that the products have high refractoriness, dense bulk density, low porosity Excellent high temperature creep property and good volume stability.
We support custom-made special-shaped clay refractory bricks, which can be customized according to drawings.
