Gunning Material for Converter
1.Based on high pure magnesia, as the main raw material;
2.adding various compound anchoring agent, ;
3.By mixing and refining.
1.High refractoriness ,excellent resistance for spall , high tap density
2.Easy to spray and sinter, Adhesive rate reach 94% , low rebounding ;
3.Long service life ,once can last 10-24 hours ;
Construction method :
1.using quantity:for 30 tons converter, one ton /time
2.Using method : to fill Gunning Mass into the spraying tank (compressed air without water under 2.2-0.4pa ); and then spray to the part need to be repair .
3.After spraying , there will be 20 minutes for sintering ;
4.Note: if somewhere occur weak situation,must stick the brick firstly ,and then spray again .
Application:BOF impact ,hot patching repairing .
