Development of flux-cored wire of Fe – C – Si – Mn – Cr – W – V system with additives of carbon-fluorine-containing material and titanium

The paper considers research of quality the electric arc coating obtained using flux-cored wire Fe – C Si Mn Cr W V system with additives carbon-fluorine-containing material and titanium. formation an was carried out automatic welding machine ASAW-1250 a new chromium-containing on plates made St3 steel. To exclude mixing deposited metal substrate steel, multilayer surfacing conducted. mode calculated refined experimentally. authors studied composition properties surface after surfacing. As substitute for amorphous carbon they used (dust gas purification aluminum production). Surfacing under flux from slag produced by silicomanganese high content sulfur. A regression analysis influence layer’s chemical its hardness wear rate mathematical models investigated performance characteristics were obtained. With increase in chromium, tungsten, silicon, resistance to abrasive increase. results conducted make it possible develop measures ensuring required level can be forecast layer when changes, predict operational rolling rolls wires PP-Np-35V9Kh3SF type. Mathematical help clarify mechanism hardening protective layers means coatings wires.
