Amorphous Refractory Materials for Mineral Thermal Furnaces
- Product Description
-
Zhengzhou Kexin Refractory Materials Co., Ltd. primarily uses high-purity, premium-quality MgO, alumina, corundum, magnesia-alumina spinel, and magnesia-based plasticizers as raw materials, combined with environmentally friendly carbonaceous binders and resins through a mixing and kneading process. This product boasts excellent thermoplasticity and an ideal drying-curing time, ensuring that the magnesia-based gunning mix exhibits outstanding flowability at high temperatures in the slag-iron tapping area. It easily forms a stable, dense mud layer, effectively protecting the refractory materials around the slag-iron tap. Moreover, the magnesia-based gunning mix reacts with MgO, FeO, and SiO₂ present in the molten slag and iron to form high-melting-point compounds, significantly enhancing the material's resistance to erosion and scouring by the molten slag and iron. The carefully selected, high-density raw materials, coupled with a scientifically optimized formulation, minimize the amount of binder required, promoting the development of a tightly packed microstructure that offers superior resistance against slag and iron penetration. Additionally, the curing and carbonization process of the binder can be precisely controlled, allowing for tailored formulations that account for factors such as the specific mineral heat furnace smelting process, operating temperature, gunning machine specifications, and tapping machine power. This flexibility ensures optimal performance, making the magnesia-based gunning mix a highly cost-effective and efficient refractory solution for sealing and protecting alloy-smelting furnaces.

Blast Furnace Clay for Ferroalloy Plants
Ferroalloys are crucial additives in steelmaking, used to adjust the chemical composition of steel and enhance its performance. Ferroalloy furnaces are specialized industrial melting devices designed specifically for producing ferroalloys. These smelting equipment types include submerged arc furnaces, blast furnaces, electric arc furnaces, and induction furnaces. As ferroalloy furnaces evolve toward larger-scale operations, increased automation, energy efficiency, and environmental sustainability, the demands on their furnace sealing materials are steadily rising. Operators have already recognized the critical importance of these materials, and simply copying or transferring existing solutions no longer meets modern production requirements. Zhengzhou Kexin Furnace Materials Co., Ltd. can develop tailored operational strategies and produce customized products based on key parameters such as equipment operating principles, smelting environments, product characteristics, and specific handling methods—ensuring that customer needs are met more effectively than ever before.
Baking-Free Ramming Material for Ferroalloy Furnaces
Iron alloy furnace non-baked ramming material is an unshaped refractory designed for lining construction or repair in iron alloy furnaces. Its key feature is that it can be used directly without the need for baking, simplifying the construction process and significantly reducing the lining installation timeline. Commonly applied to areas such as furnace bottoms and walls—both during new construction and repairs—it’s especially well-suited for smelting environments where high construction efficiency is critical.
Refractory castables for ferroalloy furnaces
Refractory castables for ferroalloy furnaces are specially designed, unshaped refractory materials tailored for the high-temperature, highly corrosive, and severely eroded areas of these furnaces. They are produced by mixing refractory aggregates, powders, binders, and additives, then casting them into shape. The formulation of these castables must be customized based on the specific alloy being smelted (e.g., silicon-based, manganese-based, or chromium-based), the composition of the furnace slag, and the operational process—making them a critical refractory material that ensures the long-term, reliable operation of ferroalloy furnaces.
Castable for ferroalloy ladles (tanks)
The castable material used for ferroalloy ladles (tanks) serves as the lining material inside containers designed for holding and transporting molten ferroalloys. It must withstand high-temperature molten iron erosion, slag attack, and thermal shock. Composed of a blend of refractory aggregates, fine powders, and binders, the formulation of the ferroalloy ladle castable needs to be tailored specifically according to the melting temperature of the ferroalloy type (e.g., silicon-based, manganese-based, or chromium-based) and the characteristics of the associated slag. This material is critical for ensuring safe transportation of ferroalloys and significantly extending the service life of the ladle itself.
