Refractory materials, as the name implies, are a kind of refractory materials. Strictly speaking, the application of refractory materials is very extensive, especially in the field of industrial production. At present, many industrial productions require high-temperature technology as support, which…
Clay bricks and high-alumina bricks are different in appearance. The former is rougher, while the latter is smoother. High-alumina bricks and clay bricks are not only different in alumina content. Their production processes are similar, but the clinker content in…
How strong are lightweight mullite insulation refractory bricks? Mullite insulation bricks can not only play the role of heat insulation, mullite insulation bricks JM-23, JM-26, JM-28, JM-30 series lightweight insulation refractory bricks are a kind of insulation refractory material, which…
During the operation of cement rotary kilns, refractory materials in the kiln are frequently subjected to thermal, chemical and mechanical stresses, which can cause different forms of damage. The consensus reached through the operation practice of cement kilns is that…
The temperature in the AOD furnace is about 1500-1800℃ during smelting. During actual smelting, due to the discontinuity of furnace operation, the temperature difference on the surface of the lining bricks is large, causing intermittent breakage of the lining surface,…
Common refractory materials used in glass melting furnaces are mainly divided into four categories: fused casting refractory materials, sintered refractory materials, amorphous refractory materials and thermal insulation refractory materials. Each type of material contains several types. The chemical composition, physical…
Kilns for metallurgy and other purposes operate continuously at high temperatures for a long time, and refractory materials work in poor conditions and are easily damaged. , but they can be summarized as follows. 1. Slag erosion Erosion caused by…
1. Product introduction of ceramic fiber blanket The tube-type heating furnace tubes in the petrochemical field usually need to be sealed and filled. The sealing method for the heating furnace tubes is usually to use ceramic fiber blankets or ceramic…
Participating in the 2025 Nanjing Lead and Zinc Industry Conference, old and new friends will attend the event together. We are committed to providing high-quality and reliable refractory products and technical services for the global non-ferrous metal smelting kilns and…
In the field of high-temperature industry, the choice of refractory materials for kilns and industrial furnaces directly affects the equipment life, energy consumption and production efficiency. High-alumina bricks have become the core lining material due to their excellent refractoriness, corrosion…
In the power industry, kilns are the key equipment to ensure the efficient operation of power generation and related links, and different types of kilns play an important role in their specific application scenarios. 1. Circulating fluidized bed boiler Circulating…
In the glass industry, the kiln is the key equipment for glass production, its variety, different types of kiln for different glass production process and scale, the following are several commonly used kiln: 1. Glass melting kiln Glass melting kiln…
