Difference between refractory castable and lightweight castable
2021 11 02
What is the difference between refractory castable and lightweight castable? Refractory castable is a general term of castable. According to the pore density of castable, it is divided into light refractory castable and heavy refractory castable. Generally speaking, the refractory castable refers to heavy refractory castable in a broad sense. What is the difference between heavy refractory castable and light castable? The main differences are as follows: Volume density of castable; Bulk dens...

The lining of high-temperature kiln is built with refractory materials. As the lining of kiln, refractory materials are eroded by gas and liquid in the long-term high-temperature environment, resulting in the destruction of kiln lining. Therefore, it is necessary to use high-quality refractory materials to repair the kiln. What are the repair refractory materials? Furnace repair refers to the furnace shutdown or non shutdown repair operation for the regular or sudden local damage or easily da...

What if the high alumina castable solidifies too fast?
What if the high alumina castable solidifies too fast?
2021 10 25
When high alumina castable is constructed in summer, it is damp when the temperature is high. During construction, it will condense too fast, so that it will be impossible to construct. What’s going on? There are several reasons. First, the high alumina castable and high alumina cement are added too much, which will cause the setting speed to be too fast, and the initial setting can not be constructed at all. This will result in low strength in the later stage and can no longer be const...
