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.
Burning Rotary Kiln Castable Material
The castable for rotary kiln firing is an unshaped refractory material specifically designed for lining the high-temperature section of rotary kilns. It is formed by mixing refractory aggregates, powders, binders, and other components into a pourable consistency. Tailored to withstand the unique challenges of rotary kiln operation—such as high temperatures, abrasion, and chemical erosion—the formulation of this castable is carefully adjusted based on factors like the kiln's internal material characteristics (e.g., alkali content, viscosity), temperature distribution, and rotational speed. As a result, this material plays a critical role in extending the service life of the kiln lining and reducing maintenance frequency.
Charging Machine Tamping Material
The ramming material for iron casting machines is an unshaped refractory material used in areas where molten iron is received and cast into shape. It is applied via a tamping process, requiring excellent resistance to high-temperature molten iron erosion, outstanding wear resistance, and superior thermal shock resistance. By optimizing the hardness of its aggregate and enhancing the performance of the binder, this ramming material not only ensures efficient iron casting but also helps extend equipment lifespan while reducing maintenance costs.
