Castable, refractory castable

In the metallurgical industry, refractory castables are used in metallurgical furnaces and thermal equipment in almost every production link, from iron ore sintering, coking, iron smelting, steel making, external refining, continuous casting to steel rolling production.The inner side of the large blast furnace shell is sprayed with refractory paint, the special part of the bottom of the furnace is rammed with refractory, and the repair is made with refractory gunning and injection.From using alumina - silicon carbide refractory ramming material to using refractory castable material, the quantity of iron flowing through iron ditch of large blast furnace was increased significantly.

 

In addition, blast furnace gunmud is all using amorphous refractories.Refractory castable is widely used in the lining of hot air valve of hot air blast furnace, and most of the lining of hot air pipe of hot air blast furnace and blast furnace are made of refractory castable.Lining of point furnaces, heat preservation furnaces and large chimney for iron ore sintering is made of refractory plastics, refractory castable and refractory spray paint.

 

The application of refractory gunning and filling in steelmaking is more and more, and the application of amorphous refractory material in the lining of shengsteel drum is also increased obviously, which gradually becomes the key point of development and application.In the field of continuous casting, it is used as the lining of continuous casting tundish and slag retaining weir plate.Non - shaped refractory materials are used in the dip pipe, integral spray gun and vacuum degassing device.The amorphous refractories used in soaking pit and heating furnace for steel rolling production are widely used and have the most remarkable effects.In coking the main use of refractory mud, in addition, also used for dry quenching furnace lining and coke oven door, flue, resistance wall and other parts.

 

In the nonferrous metallurgy industry, amorphous refractories are mainly used in electrolyzer, lead and zinc airtight blast furnace, aluminum reflective furnace, copper smelting frequency induction furnace, copper smelting flash furnace, anode furnace, electrode furnace, converter and other important equipment.

Other industries

Amorphous refractories are used in induction furnace, salt bath furnace, heat treatment furnace lining and so on.In the field of energy and chemical industry, it is used in gas generator, shale retort, pressurized atmospheric pressure furnace, vacuum heating furnace, first and second stage reformer of ammonia plant and exhaust cylinder.In addition, it is also used for lining of boilers in general industrial boilers and power plants.In the building material industry, it is mainly used in the lining of cement rotary kiln and some parts of glass melting kiln.
