Product Overview
Our refractory customized industrial electric furnace roof prefabricated parts are specifically designed and manufactured to meet the stringent requirements of various industrial electric furnaces. By adopting advanced production processes and high-quality raw materials, we ensure that the products can operate stably under harsh working conditions such as high temperature and high pressure, providing reliable support for your industrial production.
Raw Materials
- High-quality Refractory Aggregates: High-purity bauxite, silicon carbide, etc. are carefully selected as the main aggregates. High-purity bauxite has a high refractoriness and good thermal shock stability, which can effectively resist high-temperature erosion. Silicon carbide endows the product with high thermal conductivity and excellent wear resistance, greatly improving the comprehensive performance of the prefabricated parts.
- High-performance Binders: Special cements, resins and other binders are used. They can combine tightly with the aggregates at high temperatures to form a firm and stable structure, ensuring that the prefabricated parts will not crack or peel off during long-term use, and guaranteeing the service life of the products.
- Additives: A small amount of additives with special functions, such as antioxidants and accelerators, are added. Antioxidants can prevent the product from being oxidized at high temperatures and extend its service life. Accelerators can speed up the curing speed of the product during the production process and improve production efficiency.
Performance Advantages
- High Refractoriness: The refractoriness can reach above 1800°C, which can withstand the ultra-high temperature environment in the industrial electric furnace, effectively avoiding problems such as deformation and melting caused by high temperature, and ensuring the safe and stable operation of the electric furnace.
- Good Thermal Shock Stability: Through special process treatment, the product has excellent thermal shock stability and can withstand frequent temperature fluctuations. Under the working conditions of rapid cooling and heating, it can still maintain its structural integrity, reducing the frequency of maintenance and lowering production costs.
- High Strength and Wear Resistance: The product has a dense structure and high mechanical strength, which can withstand the impact and friction of materials in the electric furnace. At the same time, its good wear resistance extends the service life of the furnace roof prefabricated parts, reduces the number of replacements, and improves production efficiency.
Customization Services
- Size Customization: According to your electric furnace specifications and design requirements, we can accurately customize the size of the furnace roof prefabricated parts to ensure a perfect fit with the electric furnace, convenient installation and seamless docking.
