Product Description

ramming mixing for refractory Materials

ramming mixing for refractory Materialsramming mixing for refractory Materials

 

Refractory Ramming is unshaped refractory materials that don’t need firing and features fluidness after adding water. It is mixed with grain, fines and binder in fixed proportion. It can replace special shaped refractory materials, and can be used directly without firing, easy to construct and has a high utilization rate and high cold crushing strength.

They are widely used in the glass industry, etc. It is easy use for construction, convenient and efficient, high intensity, labor saving and the whole construction completion period will be shortened.
