Wollastonite For Welding Electrode

Wollastonite is used as electrode coating ingredient, which can play the role of melting aid and slagging additive, inhibit welding discharge, reduce splashing, improve the fluidity of slag, make the weld Forming neat and beautiful, enhance mechanical strength.General requirements for wollastonite in welding rod :SiO245%~55%,CaO35%~45%,MgO less than or equal to 0.8%,S less than or equal 0.03, P is less than003%.
