Quickly solve the problem of baking burst of refractory castable
Quickly solve the problem of baking burst of refractory castable
2021 12 31
At present, there are two main measures to improve the burst resistance of refractory castables, reasonable drying and heating system and the application of explosion-proof additives. Due to the different production conditions of various kilns, it is difficult to formulate a unified and reasonable drying and heating up system. Therefore, anti burst substances are often added to improve the burst resistance of refractory castables. The new high strength erosion resistant castable has excellent...

Difference between self flowing castable and high alumina castable
Difference between self flowing castable and high alumina castable
2021 12 28
There are differences between self flowing castable and high alumina castable, and the biggest difference is from process ratio and construction method. high alumina castable Self flowing castable is a new construction method based on the castable of low cement series. It is a material flowing and degassing by its own gravity. It is characterized by no vibration, no insertion and tamping, and no support of molds. Therefore, it reduces a lot of construction costs and labor intensity. Before th...

How to choose refractory castable under different conditions?
How to choose refractory castable under different conditions?
2021 12 10
Firstly, the kiln environment, service location, service temperature and erosion performance should be considered. In case of working layer, heavy refractory castable with high temperature resistance shall be selected. If the corrosivity is acidic and high-strength wear-resistant castable, the castable with acid resistance shall be selected. If the erosion is alkaline, the castable with alkali resistance shall be selected. Castable with strong slag erosion resistance shall be used at the par...

What are the reasons affecting the quality decline of refractory castable?
2021 12 08
Castable, also known as refractory castable, is a kind of granular and powdery material made of refractory material and binder. It has high fluidity and is formed by pouring. Compared with other amorphous refractories, the binder and moisture content are higher and the fluidity is better. Therefore, the castable has a wide range of applications. The materials and binder used can be selected according to the service conditions. It can not only be directly poured into lining, but also be made i...

How much water is added during the construction of refractory castable?
How much water is added during the construction of refractory castable?
2021 12 06
Refractory castable is an amorphous refractory made of refractory aggregate, powder, additives and binder according to the formula. A certain amount of water needs to be added during construction, and the amount of water has become a big problem during construction. When a small amount of water is added, the refractory castable can not be fully stirred, the amount of water is large, and the refractory castable is not easy to form, which affects the use and construction of refractory castable....
