What are the advantages of using homogenized material for refractory castables as refractory raw materials? Refractory castable is an unshaped refractory material mixed with refractory aggregate, powder and additive binder. When selecting refractory raw materials for refractory castables, there are homogenized materials and non-homogeneous materials.

The homogenizing material is generally bauxite homogenizing material, which belongs to a new type of high-quality synthetic refractory material. It is a high-quality refractory raw material formed by crushing, purifying, batching, grinding, iron removal, molding, drying, high-temperature firing and other steps. Bauxite homogenizer is a synthetic raw material with high purity content, high bulk density, high temperature resistance, erosion resistance and higher use value.

Synthetic homogenizers or homogeneous materials often used in refractory castables are: spinel, mullite, etc. The main crystal phase of the bauxite homogenizing material formed by high temperature is α-Al2O3, the cross section is blue-black, the texture is dense, the grains are regularly developed, and the physical indicators all reach the level of the produced homogenizing material. It has stable physical and chemical indicators, uniform composition, large bulk density, excellent high temperature performance, no need for grading and sorting when using, and has the characteristics of low comprehensive cost and high cost performance.

Generally, refractory bricks and unshaped refractories can be produced when homogenized materials are used. The refractory castables include high-strength wear-resistant castables, corundum castables, plastics, spray coatings and other uncertain refractories; refractory bricks include heating furnace bricks, aluminum-magnesium refractories Carbon bricks, aluminum-magnesium spinel bricks and other shaped refractory materials, refractory materials and refractory prefabricated products produced with homogenized materials can be widely used in high-temperature furnaces in cement, steel, glass building materials and other industries.

The homogenized material has high density, and the homogenized material is used as the refractory raw material of the unshaped refractory material.
