Explanation
unshaped refractory constructed by mechanical spraying with pneumatic tools. Composed of refractory aggregate, powder, and binder (or with additives). As the materials composed of cement and aggregate are repeatedly and continuously impacted during the spraying process to promote the compaction of the sprayed materials, the spraying layer has good efficiency of spare filling and mechanical strength.
