1. Classification by chemical properties Acidic refractory: fait généralement référence à un réfractaire avec une teneur en SiO2 supérieure à 93%. Sa principale caractéristique est qu'il peut résister à l'érosion des scories acides à haute température., mais il est facile de réagir avec les scories alcalines. Réfractaire alcalin: fait généralement référence aux réfractaires avec de l'oxyde de magnésium comme composant principal. […]
The silicon carbide rod begins to oxidize when used in the air to 800℃. When the temperature reaches 1000-1200℃, a protective silicon dioxide film is formed on the surface of the heating part. At 1200℃, cristobalite is formed. When the temperature rises above 1527℃, the protective film will be damaged and the oxidation rate will […]
Overview of ceramic fiber products First, the raw materials and basic production technology of ceramic fiber products The raw materials of ceramic fiber products are mostly high purity clay clinker, poudre d'oxyde d'aluminium, poudre de silice, sable de chrome-quartz et ainsi de suite. Prenons l'exemple de la production de coton en fibre céramique, these raw materials are fused […]
Dans les applications industrielles, la fibre céramique et la fibre de verre sont des matériaux d'isolation thermique et d'isolation importants, chacun avec des propriétés et des utilisations uniques. Ce qui suit est une comparaison simple et claire entre les deux: Material composition Heat resistance Insulation performance Chemical stability Application areas Ceramic fiber Mainly made of inorganic materials such as bauxite and silicate, with […]
Aluminum soil, also known as aluminum ore, is an important industrial ore. Its main component is alumina (Al2O3), and it also contains certain impurities. The use ofbauxiteis very wide, mainly including: 1.bauxite is one of the main raw materials for production of aluminum. Through high temperature smelting, bauxite can be converted into metal aluminum. Aluminum […]
1.Classification of refractory materials for torpedo tanks (1)Refractory materials for working layer: mainly aluminum carbide silicon carbon bricks are used. This material has good thermal shock stability and can adapt to the temperature difference of up to 800℃ in the torpedo tank. It also has high strength, good mechanical erosion resistance and wear resistance, as […]
As a high-performance refractory material, magnesia-alumina spinel bricks have broad application prospects in cement kilns, steel smelting and other fields due to their excellent thermal shock stability, improved load softening temperature, strong erosion resistance, excellent physical properties, good thermal insulation performance, excellent wear resistance and erosion resistance, as well as environmental protection and sustainable development. […]
Many ceramic and metal materials will be damaged if they are in high temperature, reduction, oxidation and other environments for a long time. Such problems can be solved by coating the surface of the material with a compound coating material that can remain stable in the use environment. Mullite has stable chemical properties, good corrosion […]
1.Construction: Castables are usually used for pouring concrete. Par exemple, in foundation engineering, castables can fill the foundation, enhance the bearing capacity of the foundation, and make the building more stable. In underground pipeline construction, castables can also be used to fill the gaps around the pipeline to enhance the structural strength of the pipeline […]
High-alumina anchors refer to high-alumina refractory bricks with a specific shape that are installed on the steel structure of the industrial kiln shell or supporting the furnace lining and embedded in the refractory lining to serve as anchors and links. Anchor bricks are generally used in furnaces, also called hanging bricks. They are a new […]
