Blast furnace hot blast furnace spray coating is a high-performance spray coating launched by Zhengzhou Rongsheng Kiln Refractory Co., Ltd. It is suitable for the furnace body and hot air ducts of the ironmaking system, especially for the protection of the furnace shell of blast furnaces and hot blast furnaces. The product is based on high-quality refractory materials such as mullite and corundum. It has excellent properties such as acid resistance, wear resistance, and corrosion resistance. It can effectively protect the furnace shell and extend the service life of the equipment. Blast furnace hot blast furnace spray coating has a good thermal insulation effect and can remain stable in a high temperature environment. The refractoriness reaches 1510℃ to 1610℃, and the applicable temperature range is 1200℃ to 1400℃. The volume density and flexural strength of the product are also very suitable for the needs of industrial kilns and furnaces, and can meet the strict requirements of various high-temperature working environments. Zhengzhou Rongsheng Kiln Refractory Co., Ltd. uses advanced production processes and automated intelligent production lines to ensure the stability and consistency of product quality, which can be widely used in metallurgy, electric power, chemical industry and other industries. Through in-depth cooperation with many universities and scientific research institutions, the company continues to innovate and is committed to providing customers with high-quality, high-performance, cost-effective refractory solutions.
