They are composed essentially of CaO-Al2O3-SiO2 with addition of fluxing agents and carbon.Mold fluxes have different functions:to provide chemical protection of liquid steel from oxidation;to provide thermal insulation preventing solidification of steel surface;to lubricate the strand to the mould to provide uniform heat transfer between the strand and the mould wall.In order to maintain such highly specific and critical technological properties in SINTHESIS series itâs necessary to strictly monitor raw materials, production operations and final products by means of efficient Q&C procedures.Section:(120-200mm)Ãmm)Casting speed:0.8-1.5m/minApplicable steel:201,J1,J3 etc
