Acid Resistant Castable

Acid resistant castable can be directly put into use in projects without sintering. Moreover, the fluidity of acid resistant refractory castable is better and the construction is convenient. It is easier to achieve the ideal construction results by using it. Its maximum operating temperature is 1000℃(1832℃).

Usage Advantages of Acid Resistant Refractory Castable

Energy saving: eliminate the high energy consumption firing process, only need to shape, dry and bake. Energy consumption is 5% – 6% of sintered refractory bricks.

Simple manufacturing process: the production efficiency of acid resistant castable is 4 to 9 times that of refractory bricks.

High construction efficiency: the construction efficiency of refractory castables is 6 to 15 times that of bricklaying. It can make integral special-shaped furnace linings. It can also be used to quickly repair kilns and improve their life and operating rate.

Suitable for all kinds of high-temperature projects: Kerui uses masonry materials prepared with special high-quality materials. It has good thermal shock resistance and spalling resistance. In addition, it resists the erosion of harmful gases and slag.

Can be shaped arbitrarily: it can also make various irregular refractory precast for use. Reasonable use can give full play to the performance of acid-resistant castables.

Precautions for Acid Resistant Castable

You must pay attention to these during use and try to give full play to the greater characteristics of acid-resistant castables and refractory ramming mass.

  • During the use of acid-resistant castables, you should pay attention to not using them for a short time or in an environment with a large temperature difference.
  • You should also not construct them in a humid environment.
  • Moreover, acid resistant refractory castables should not be constructed under high temperatures. This will destroy its performance and reduce the strength of the acid-resistant castables.
