Monolithic refractories
“Monolithic refractories” is a general term for refractories of granular material and clay type.
There are castable refractory materials, gunning materials, patching materials, and others which can be used in various ways depending on the particular purpose.
-
Gunning materials
Gunning materials are mainly used to make repairs. They are mixed with water and sprayed on the walls of converters, electric furnaces, AOD furnaces, etc. using compressed air. -
Castables
Castables are powdered refractories that are mixed with refractory aggregate and alumina cement, etc. They have hydrating chemical bonding properties and used for castings, etc.
They are also used widely in manufacturing ladles and tandishes. -
Acid proof castables
Acid proof castables are one type of castables using silicate or other acid-resistant bonds. They have acid resistance and is used for lining chimneys, etc. -
Ramming material
An amorphous refractory material that is designed to be hit and fixed in place using an air rammer. Used in ladle and furnace manufacture. -
Patching materials
Patching materials are monolithic refractories which are used to make partial repairs. They are kneaded by adding water, etc. to plastic materials, and then pressed in place using the hands or trowels. -
Coating materials
Coating materials are refractory materials which are applied to the surface of objects by troweling or spraying in order to form a fireproof coating. -
Fireproof mortars
Fireproof mortars are joint materials used in the laying refractory bricks. There are three types: heat-setting, air-setting and hydraulic types. -
Magnesia clinker
The main component of Magnesia clinker is MgO. This is also used as refractory raw materials. There are naturally and artificially (seawater magnesia) derived, and it is used for furnace bottom stamping with the addition of water and bitterns. -
Dolomite clinker
Dolomite clinker is a clinker made by mixing additives into dolomite, as needed, and is used for the bottom electrode area of electric furnaces.
