1.Ramming mass Description

Ramming material refers to the unshaped refractory that is constructed by the ramming method and hardened under heating above normal temperature. It is made by mixing refractory aggregates, powders, binders, admixtures with a certain level of water or other liquids. It is used to fill the gap between the furnace cooling equipment and the masonry or the filler for the masonry leveling layer.
