Fireclay brick refers to the Al2O3 content of 45%-48% of aluminum silicate material clay products. Fireclay brick advantages is remarkable, belong to weak acidity refractory product, color is flaxish yellow, palm yellow color more. Fireclay brick is widely used in metal smelting industry and chemical industry. Therefore, the quality of refractory brick is also very critical, we will be introduced in detail for you.

From the appearance, the poor quality fireclay brick has a large number of black spots on the appearance, and the distribution is dense, the black spots represent the impurity of iron oxide. The more black spots, the more impurities, the less refractoriness. Can also touch the surface of fireclay brick is smooth, quality fireclay brick, smooth surface, no cracks, do not sting. Poor quality clay bricks are rough to the touch, some even have big cracks and are very sharp. We should know that cracked clay bricks have low compressive strength and are prone to fracture.

Above is how to distinguish the quality of fireclay brick introduction, hope to help you. Everybody purchases refractory brick to should choose reputation good refractory material company, quality has assurance. Zhengzhou Rongsheng Kiln Refractory Co.,Ltd.
