Anti-corrosive property means the ability to resist various kinds of corrosive medium under high temperature, such as slag, fuel, glass melting liquid, acid, alkali, electrolyte liquid and gaseous substances. Anti-corrosive property is a very important index to measure the chemical corrosion and mechanical wear of fused cast azs block.

However, what are the factors that can affect the Anti-corrosive property of fused cast azs block? The following several aspects are for your reference.

1. The chemical and mineral composition: refractory bricks with different chemical composition have different ability of anti-corrosive, generally speaking, acid resistant brick has good corrosion resistance to acid corrosion medium, and alkaline refractory brick is very weak to against acidic corrosive medium corrosion. The refractory brick is a group of multi-gathering which is composed of main crystal phase and matrix. Main crystal phase with high refractoriness, large grains, and less grain boundaries has relatively better corrosion resistance. Matrix with high impurity content is easy to form a liquid phase, if the liquid phase viscosity is low, the corrosion resistance is poor.

2. The bulk density, apparent porosity, thermal shock resistance, oxidation resistance: refractory brick of high bulk density and low porosity is more corrosive than relatively loose brick; A refractory brick with bad thermal shock resistance will appear crack, so that the corrosion medium will get into the interior of the refractory brick and result in the corrosion resistance drop. Carbon refractory brick with poor antioxidant will loose its layout and fall easy after the surface being oxidation, and then corrosion resistance will decrease.

3. Application conditions: Mainly contain temperature and shake situation, pressure, atmosphere, touching moment and area. The temperature is high, the shake is big, the pressure is big, the air is corrosive, the touch is long and the area is big, the corrosion of the material is more severe.

In a word, the factors affecting the corrosion resistance of fused cast azs block are complicated.
