Pay attention to the following points when using refractory materials:
1)After pouring, if it is not fully cured, the lining body is often damaged before sintering due to its low early strength and loose structure. The lining body will heat up suddenly and sometimes burst.
2)The thickness of the lining body is thin, the pouring space is small, and t...

The main reference indexes of refractory bricks are the following three points:
1. Refractoriness
The refractoriness of high alumina bricks is higher than that of clay refractory bricks and semi-silica bricks, reaching 1750~1790℃, which is a high-grade refractory material.
2. Load softening temperature
Because high-alumina products have high Al2O3, ...

High alumina bricks are differentiated based on the amount of aluminum oxide (Al2O3) content. Currently, 48%, 55%, 60%, 65%, 73%, 75% content are often used, and of course there are higher content. The above is attributed to corundum.
According to the content of 55 or less, it is called clay brick, which is a neutral refractory material, which is ma...
