Gunning Material for Converter Production Technics: 1.Based on high pure magnesia, as the main raw material; 2.adding various compound anchoring agent, ; 3.By mixing and refining. Production Features: 1.High refractoriness ,excellent resistance for spall , high tap density 2.Easy to spry and sinter, Adhesive rate reach 94% , low rebounding ; 3.Long service life ,once can last 10-24 hours ; 4.Minimum pollutants 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 . Quality Table:
