What are the functional advantages of A-grade fireproof rock wool board in industrial cement plant areas? The fire rating of rock wool sound-absorbing board is A-level non combustible material, which is the highest fire rating in the Chinese national standard GB8624. It belongs to completely or almost non combustible materials and will not produce toxic smoke or droplets in a fire. Specifically, Class A includes two levels: A1 (completely non combustible) and A2 (limited flame spread). Rock wool sound-absorbing panels usually meet the A1 standard, with a melting point exceeding 1000 ℃, which can effectively prevent the spread of fire and maintain physical stability.

In the field of industrial production, safety and energy conservation in the factory area have always been the core issues of concern for enterprises. Fire hazards, energy loss, and other issues not only affect production efficiency, but may also cause significant economic losses and safety threats to enterprises. The rock wool roll felt launched by Rosewool Insulation Refractory Co.,Ltd. has become an ideal choice for industrial plants to solve these problems due to its A-level fire resistance, excellent thermal insulation, sound absorption and noise reduction performance, and to build a strong safety and energy-saving defense line for industrial production. ​

Many cooperating steel mills have provided feedback that using our insulation materials can reduce the temperature of the blast furnace outer wall by more than 30%, and save 30000 to 50000 yuan in monthly electricity bills for a single production line. Have you paid attention to this energy consumption loss in your factory?

High density calcium silicate board, as a high-quality building material, has a wide range of applications in the industrial field. Its high strength, excellent fire resistance, and corrosion resistance make it the preferred material for many industrial projects. The HCS-20 high-temperature resistant calcium silicate board lining board for furnace insulation in industries such as electric power, metallurgy, petrochemicals, construction, shipbuilding, and cement is a thermal insulation material for boiler bodies and industrial kilns. According to the usage requirements, the HCS-20 type calcium silicate board can withstand a high temperature of 1000, and the HCS-25 type can withstand a high temperature of 1100.

In the industrial context of cement production, core equipment such as rotary kilns, preheaters, and grate coolers are like beating hearts, continuously enduring thousands of degrees of high temperature quenching. The performance of its internal insulation lining directly determines the energy consumption level, operational safety, and equipment lifespan. Choosing a reliable internal insulation material is crucial in the face of harsh working conditions. Rosewool Insulation Refractory Co.,Ltd is a 1050 ℃ high-temperature resistant calcium silicate board specially designed for the cement industry. With its excellent comprehensive performance, it has become a strong shield lining to protect high-temperature equipment in cement plants.

The 2025 China (Chengdu) Steel Casting and Metallurgical Materials Enterprise Supply and Demand Negotiation Summit has begun. As a representative of the strength in the field of insulation and refractory materials, Rosewool Insulation Refractory Co.,Ltd. has been invited to participate in this industry event with customized high-temperature solutions, bringing new choices for cost reduction and efficiency improvement to steel and metallurgical enterprises.
