Description of Refractory LZ-48 LZ-55 LZ-65 LZ-75 High Alumina Anchor Brick High Alumina Refractory Brick For Heating Furnace
Anchor fire brick is a new type of non-combustible refractory materials,which is made of refractory aggregate,refractory fines,binders and other additives. In construction, mix binders and matrix evenly(aggregates and fines) and add water(or other liquid)to make mortar by agitating,then it can be used for casting.this product is widely used in heat-treatment furance,soacking furance and petro-chemical installation as the foundation of thermal equipments and industrial furanaces.
