the coil grout forms a smooth sliding surface on the inner surface of the coil, so that the lining can be expand and contract freely during the frequently thermal changes. It also can effectively prevent the transverse cracks and increase the safety of the furnace. and in a certain period of time the coil material can block the penetration of molten metal.
In order to obtain a long service life, high strength and low short circuit coil grout, it has to select suitable one depends on customer’s production situation, and meanwhile strictly control the installing and drying process, and proper maintenance is required.
Only high-purity, high-quality raw material can be used as coil grout. The material should be installed flat and smooth. If the furnace has push out block, it is necessary to make a taper shape.
SFR can provide customers with nearly ten kinds of coil grout, two colors (red and white), two kinds of construction methods (paste and cast), we can fulfill different requirements of customers.
