Product Description

Long Service Life High Strength Anti-alkali Refractory Castable for Decomposing Furnace
The Description:
Alkali refractory castable is a refractory castable that can resist the erosion of metal oxides. It is mainly composed of a mixture of refractory aggregate, binder aggregate, binder and alkali resistant agent. If the porosity is divided, more than 45% is light alkali refractory castable, and less than 45% is heavy alkali refractory castable.

First, alkali refractory castable characteristics:

1, Good high temperature performance;

2. Strong alkali resistance and corrosion resistance;

3, Can resist the erosion of sodium salt melt;

Second, the scope of application of alkali refractory castable:

Alkali-resistant refractory castables are mainly used in industrial furnaces with alkali corrosion in steel, nonferrous, glass, machinery, petrochemical and other industries. Among them, the heavy alkali refractory castable is mainly used in the kiln tail, kiln head, preheater, discharge port, tuyere and other parts of the roasting alumina rotary kiln and cement rotary kiln. Light alkali refractory castable Zhu Yong is used for the preheater top cover, cylinder body and thermal insulation lining in the kiln.
