Refractory gunning mass for blast furnace lining repair High strength refractory For Steel Making
The mixture ratio of blast furnace gunning mass needs to meet the following conditions:
It achieves the required strength, less rebound, less spray dust, good adhesion and no blockage of the conveying pipe, etc.
The blast furnace refractory gunning mass is divided into three types according to the order of adding water (or solution) and the amount of water used, such as wet method, semi-dry method and dry spray coating.
The series of gunning mass for blast furnace infrastructure produced by our company have the advantages of easy spraying construction, high strength and high refractoriness, which can significantly improve the service life of blast furnaces and are suitable for blast furnaces constructed by various mechanical spraying methods.
