Product Feature

The basic characteristic of steel ladle castable is that the temperature used is generally not more than 1400℃, the lining must have higher strength, better erosion resistance, good thermal shock resistance. Adding a certain amount of silicon carbide can not only improve the wear resistance and erosion resistance, but also reduce some low melting point materials.

1. The amount of added water shall not exceed 5.3%;
2. More than 35 times of thermal shock;
3. The change of post-firing line was 0.3% ~ 0.8, and the change of re-firing line was 0 ~ 0.2%.

 

The characteristics of steel ladle castable are as follows:

1. high fire resistance, high temperature performance, long service life;
2. anti-erosion, anti-stripping, corrosion resistance, wear resistance;
3. the construction process is simple, fast, low labor intensity;
4. the use of non-sticky slag, the package wall smooth.
