1. Clasificación por propiedades químicas Refractario ácido.: generalmente se refiere a refractarios con contenido de SiO2 mayor que 93%. Su característica principal es que puede resistir la erosión de escoria ácida a alta temperatura., pero es fácil reaccionar con escoria alcalina. refractario alcalino: generalmente se refiere a refractario con óxido de magnesio como componente principal. […]
The silicon carbide rod begins to oxidize when used in the air to 800℃. Cuando la temperatura alcanza los 1000-1200 ℃, Se forma una película protectora de dióxido de silicio en la superficie de la parte calefactora.. A 1200 ℃, se forma cristobalita. Cuando la temperatura sube por encima de 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, aluminum oxide powder, polvo de sílice, chromium-quartz sand and so on. Taking the production of ceramic fiber cotton as an example, these raw materials are fused […]
In industrial applications, ceramic fiber and glass fiber are important thermal insulation and insulation materials, each with unique properties and uses. The following is a simple and clear comparison between the two: 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.Clasificación de materiales refractarios para tanques de torpedos. (1)Materiales refractarios para capa de trabajo.: mainly aluminum carbide silicon carbon bricks are used. Este material tiene buena estabilidad al choque térmico y puede adaptarse a la diferencia de temperatura de hasta 800 ℃ en el tanque de torpedos.. También tiene alta resistencia, buena resistencia a la erosión mecánica y resistencia al desgaste, 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.Construcción: Castables are usually used for pouring concrete. Por ejemplo, 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 […]
