The water beam wrapping block of the heating furnace is a high-performance refractory product developed by Rongsheng Kiln Refractory Co., Ltd. to solve the high-temperature problem in the application of heating furnaces. As an important protective component of the main equipment of the heating furnace, the water beam needs the dual protection of circulating cooling water and refractory wrapping materials. Our water beam wrapping blocks adopt the casting molding process and use high-quality corundum, mullite and high-aluminum materials to ensure excellent performance in high temperature environments. The chemical composition of the product includes corundum with Al2O3≥80%, mullite with Al2O3≥55%, etc. It has high volume density, high compressive and flexural strength, and excellent linear change rate, ensuring its stability and durability during use. This product effectively avoids the problems of easy cracking and high mold cost of traditional refractory wrapping materials. It has been adopted by many steel rolling enterprises, greatly reducing the cost of overhaul and maintenance, and improving the operation efficiency of equipment. The water beam wrapping block of the heating furnace is an ideal choice for high-temperature equipment in the fields of power, metallurgy, petrochemicals, etc.
