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

1. High refractoriness and excellent mechanical strength.
2.High density,not easy leakage,
3.Excellent thermal shock resistance stability,
4.Good volume stability at high temperature,
5.Excellent erosion resistance,
6.Good slag resistance,
7.Longer and stable service life cycle to reach high efficiency.

Refractory dry ramming mix is used for the lining of smelting furnace etc thermal equipment such as ,Blast furnace iron runner and slag runner,Hot-blast cupola furnace,Lining of blast furnace,Molten steel ladle,Electric arc furnace(EAF),Matte smelting everberatory furnaces, Lining of inductionfurnace,Converter,Steel refining furnace,Rotary kiln etc.
