Blast furnace is the main equipment in the steel metallurgy industry that uses the iron ore coke reduction method to produce molten iron. With the modernization and large-scale development of blast furnaces and the implementation of strengthened smelting technology, extending the service life of blast furnaces has become the main way for steel enterprises to reduce consumption and increase efficiency. The areas that determine the lifespan of blast furnaces are mainly the furnace bottom and hearth areas, especially the abnormal erosion areas below the iron mouth. Due to its good thermal conductivity, high thermal shock stability, low coefficient of thermal expansion, and poor affinity with iron, carbonaceous refractory materials are widely used as lining materials. The working environment of furnace lining materials is harsh, and there are many factors that affect their service life. Therefore, the development of carbon bricks for blast furnaces with excellent resistance to molten iron erosion and oxidation, as well as high thermal conductivity, is of great significance for extending the service life of blast furnaces and ensuring blast furnace production.

      The existing carbon bricks for blast furnaces are usually made from smokeless coal, graphite, and petroleum coke as the main raw materials, with asphalt as the binder, and baked at different temperatures. The carbon bricks used in blast furnaces prepared by existing technology have decreased strength, thermal conductivity, and resistance to melting loss due to the high volatile content of asphalt and low residual carbon rate; The use of resin as an additive or binder facilitates the low-temperature or room temperature molding of products, but it significantly increases costs. In addition, the carbonization of resin forms amorphous glassy carbon, which has low thermal conductivity and residual carbon rate, greatly reducing the thermal conductivity of carbon bricks.

        Xinghui New Materials mainly produces anti-corrosion carbon bricks and refractory materials, with complete production equipment, advanced technology, rich production experience, and complete testing equipment; The quality of anti-corrosion carbon bricks and other products is stable and reliable, with layer by layer inspection from raw materials to finished products; Production, supply and marketing processes, networked monitoring; As always, ensure that the quality of anti-corrosion carbon bricks meets customer expectations. With the increasingly serious problem of environmental pollution, the importance of the environmental protection industry is becoming more and more apparent. As an important component of wastewater treatment equipment, the selection of lining materials is crucial. As an excellent material, anti-corrosion carbon bricks have been widely used in this field.

       Customers need to provide the operating and design conditions of the equipment when placing an order, such as temperature, pressure, medium, equipment specifications, dimensions or special-shaped brick dimensions and quantities, and other special requirements, so that we can better understand your needs and provide suitable solutions to better serve you.
