Refractory gunning castable is used high purity raw materials and additives as the main material, and made of under superfine powder adding technology.
The material has excellent structural stability and air tightness, and has high physical and chemical properties, also has a fine working ability.
As the professional refractory castable manufacturer in China, we supply an extensive range gunning castable, that are suitable to be used in furnace bottom & hot stove and copper furnaces. Manufactured using quality material, these also find extensive application for laying magnesite bricks. Our range is stringently tested to match with the international industrial standards.
This gunning refractory castable have the characteristics as below
Does not moisten the dregs, the iron.
The surface is smooth.
Easy to demolish.
Have the high intensity.
Can bear the washout and corrosion.
Reduce the construction time and worker labor intensity long the service life and so on.
Reduces the consumption of refractory materials,reduce production cost, reduces labor strength and improves working environment.
Applications of gunning castable:
Refractory gunning castable is designed for refractory lining of blast furnace iron and slag runners, skimmers and so on.
They can be used in troughs of small and mid size BFs and in all positions of the troughs where fast tapping is required.
The Throughput Can Be Over 15,000 Tons Depending on The BF Size and Operation.
