Fired Refractory Products
Fired refractory products are refractory materials obtained by kneading, molding, drying, and high-temperature firing of granular and powdery refractory raw materials and binders.
Non-Fired Refractory Products
Non-fired refractory products are refractory materials that are made of granular, powdered refractory materials and suitable binders but are directly used without being fired.
Special Refractory
Special refractory is a kind of refractory material with special properties made of one or more high melting point oxides, refractory non-oxides, and carbon.
Monolithic Refractory (Bulk Refractory Or Refractory Concrete)
Monolithic refractories refer to refractory materials with a reasonable gradation of granular, powdery refractory raw materials, binders, and various admixtures that are not fired at high temperatures and are used directly after mixing molding, and grilling material.
Functional Refractory Materials
Functional refractory materials are fired or non-fired refractory materials that are mixed with granulated and powdered refractory raw materials and binders to form a certain shape and have specific smelting applications.
Clay Bricks
Clay bricks are aluminum silicate refractory materials composed of mullite, glass phase, and cristobalite with an Al2O3 content of 30% to 48%.
Applications of Clay Bricks
Clay bricks are a widely used refractory material. They are often used in masonry blast furnaces, hot blast stoves, glass kilns, rotary kilns, etc.
High Alumina Bricks
High alumina bricks refer to refractory materials with an Al2O3 content of more than 48%, mainly composed of corundum, mullite, and glass.
Applications of High Alumina Bricks
It is mainly used in the metallurgy industry to build the plug and nozzle of a blast furnace, hot air furnace, electric furnace roof, steel drum, pouring system, etc.
Magnesium Bricks
Magnesium bricks are alkaline refractory materials made from sintered magnesia or fused magnesia as raw materials, which are press-molded and sintered.
Applications of Magnesium Bricks
Magnesium bricks are mainly used in open-hearth furnaces, electric furnaces, and mixed iron furnaces.
Corundum Bricks
Corundum brick refers to refractory with alumina content ≥90% and corundum as the main phase.
Applications of Corundum Bricks
Corundum bricks are mainly used in blast furnaces, hot blast stoves, refining outside the furnace, and sliding nozzles.
Ramming Material
The ramming material refers to a bulk material formed by a strong ramming method, which is composed of a certain size of refractory material, a binder, and an additive.
Applications of Ramming Material
The ramming material is mainly used for the overall lining of various industrial furnaces, such as open-hearth furnace bottoms, electric furnace bottoms, induction furnace lining, ladle linings, tapping troughs, etc.
Plastic Refractory
Plastic refractories are amorphous refractory materials that have good plasticity over a long period of time. It is composed of a certain grade of refractory, binder, plasticizer, water, and admixture.
Applications of Plastic Refractory
It can be used in various heating furnaces, soaking furnaces, annealing furnaces, and sintering furnaces.
Casting Material
The casting material is a kind of refractory with good fluidity, suitable for pouring molding. It is a mixture of aggregate, powder, cement, admixture, and so on.
Applications of Casting Material
The casting material is mostly used in various industrial furnaces. It is the most widely used monolithic refractory material.
