  What is the difference between insulation brick and refractory brick? The main function of insulation bricks is to keep heat and reduce heat loss. Insulation bricks are generally not in direct contact with the flame, and refractory bricks are in direct contact with the flame. High temperature bricks are mainly used for flame burning. It is usually divided into two types: amorphous refractories and shaped refractories. Amorphous refractory materials, also called castables, refer to mixed particles composed of various aggregates or aggregates and one or more binders, which must be uniformly mixed with one or more liquids with strong fluidity. Fixed refractory materials: ordinary refractory bricks have standard shape rules and can be temporarily cut as needed. The main differences between insulation bricks and refractory bricks are as follows: 1. Thermal insulation performance. The thermal conductivity is generally between 0.2-0.4 (average temperature 350±25°C), and the ...

  What is bauxite used for? Bauxite is a kind of bauxite which is made of bauxite as raw material, sintered at 1500 ℃ to form a block, ground, bagged and processed by a crusher. The sieve fineness of bauxite is about 325 mesh. It is usually used in precision casting. Yyrefractory is a professional manufacturer of all kinds of refractory grade bauxite. 1. Aluminum industry. It is used in the fields of national defense, aviation, automobile, electrical appliance, chemical industry, daily necessities and so on. Precision casting. The bauxite clinker is processed into fine powder and made into a precision casting mold. Suitable for military, aerospace, communications, instrumentation, machinery and medical equipment and other sectors. 3. Refractory products. The refractoriness of bauxite clinker is as high as 1780℃, with strong chemical stability and good physical properties. 4. Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature ...

  What is refractory ? Refractory refers to the temperature in degrees Celsius at which a conical specimen of refractory material can withstand the action of high temperatures without softening and melting under no load. However, refractories cannot be completely described by the definition of refractoriness, and 1580°C is not absolute. Yyrefractory refractory raw materials are a class of inorganic non-metallic materials whose refractoriness is not lower than 1580℃. Materials now defined whose physical and chemical properties allow their use in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, electric power and other industrial fields. They are used the most in the metallurgical industry, accounting for 50%-60% of total production. The workability of refractory materials includes consistency, slump, fluidity, plasticity, cohesion, resilience, co...
