Product Description

Product Description

 

Refractory ramming mass is made up of refractory aggregate and powder,binder and additive proportionally,using ramming method during construction.
1.Refractory aggregate:fire clay based,high alumina based,mullite-corundum based,silica based,magnesia based,carborundum based etc
2.Binder:phosphoric acid and phosphates, sodium silicate, aluminum sulfate,binding clay and  organic binder etc.

Product Specifications

 

Feature of Our ramming mass:

1. High refractoriness and excellent mechanical strength.
2.High density,not easy leakage,
3.Excellent thermal shock resistance stability,
