There are many factors to test the quality of refractory bricks, including density, porosity, etc. In fact, corrosion resistance is also an important factor in determining its quality, which may affect the use of refractory bricks during use. So what are the factors that affect its corrosion resistance?
The bulk density, apparent porosity, thermal shock resistance, oxidation resistance, and high temperature volume stability of refractory bricks have varying degrees of influence on its corrosion resistance. Dense materials with high bulk density and low porosity are relatively loose materials with better corrosion resistance;
When a material with poor thermal shock resistance is subjected to thermal shock, cracks or cracks and peeling will appear, which will cause the corrosive medium to enter the material and reduce its corrosion resistance;
Carbon-containing refractory bricks with poor oxidation resistance will form a decarburized layer after oxidation on the surface. The structure is loose and easy to fall off, which reduces the corrosion resistance;
Materials with poor volume stability at high temperatures will generally have poorer corrosion resistance.
The factors that affect the corrosion resistance of refractory bricks have been introduced for your reference only. Our factory produces and sells refractory brick products of various specifications and models, with stable and reliable quality and affordable prices.
