Types and advantages of castables for aluminum melting furnaces and refractory castables for kilns. Aluminum melting furnace castables generally use high-aluminum refractory castables. High-aluminum refractory castables are a common type of refractory castables and are graded according to aluminum content. Usually the aluminum (AL2O3) content is ≥42%. It is a refractory castable made of high-aluminum … Read more
Anchor bricks refer to high-alumina refractory bricks with specific shapes that are installed on the steel structure of industrial kiln shells or supporting furnace linings and embedded in the refractory lining to serve as anchors and connections. Furnace top anchor bricks are also called hanging bricks. Anchor bricks are usually used inside walls, furnace tops, … Read more
A hydrogen sulfide incinerator is a professional incinerator for treating hydrogen sulfide tail gas. The working conditions are very harsh, and the inside of the furnace is filled with acid gas, which can easily cause serious erosion to the furnace lining material. When designing refractory materials for furnace linings, the common factors of high-temperature environments … Read more
99 alumina ceramic ball is a high-performance wear-resistant ceramic ball. Its main component is alumina (Al2O3), which is a very hard ceramic material. Alumina ceramic balls have good stability and corrosion resistance at high temperatures. Therefore, it is widely used in abrasives, abrasives, and catalyst carriers in chemistry, mining, metallurgy, electric power, and other industries. … Read more
Low thermal conductivity mullite multi-layer composite bricks are designed with a multi-layer composite structure. Using bauxite as the main raw material, natural bauxite clinker is used as the main raw material instead of traditional silicon carbide mullite bricks. Sintered mullite is the main phase, which reduces the overall thermal conductivity of mullite bricks and effectively … Read more
Lightweight mullite bricks are also called mullite insulation bricks. Lightweight mullite insulation bricks are heat-insulating refractory materials with mullite as the main crystal phase and binding phase. High-alumina clinker is used as the main raw material, and high-quality and high-purity refractory powder is added. According to the required proportion of the product, organic composite fillers … Read more
High aluminum castable refractory is a commonly used refractory castable material. Due to its simple construction and low cost, it is used as a refractory lining material for many high-temperature industrial furnaces. In actual use, the advantages of high aluminum castable are obvious. However, its shortcomings cannot be ignored. Advantages of high aluminum refractory castable. … Read more
Sillimanite bricks for glass kilns are refractory bricks made of sillimanite minerals. Sillimanite is converted into mullite and free silica after high-temperature calcination. Generally, it is produced by the high-temperature firing method and mud casting method. Its physical and chemical properties are better than high alumina bricks, with a refractoriness of 1770~1830℃ and a softening … Read more
The corrosion resistance of refractory bricks is divided into two types: alkaline and acidic, and it is also the corrosion of both acid and alkali. Therefore, it is necessary to understand the performance of refractory bricks of different materials in order to better choose them. The types of refractory bricks are divided into silicon aluminum … Read more
Different waste incinerators, different use parts, use different temperatures. Waste incinerators need to choose refractory materials according to the operating temperature. The service temperature of the roof, side wall, and burner of the combustion chamber is 1000-1400°C. High-alumina bricks and clay bricks with a refractoriness of 1750-1790°C can be selected, and plastic refractory materials with … Read more
