THE INFLUENCE OF THE INTRODUCTION OF THE CHARGE FOR THE PRODUCTION FLUX-CORED WIRE SYSTEM WITH C – Si – Мn – Сr – V – Mo CARBON-FLUORINE-CONTAINING ADDITIVES AND NICKEL

Abstract

The paper presents experimental studies of the introduction influence of a fl ux-cored wire of PP-H-25H5FMS carbon-fluorine-containing fluoride supplements (metallurgical wastes) and powdered nickel. The introduction of the C-wire system C – Si – Мn – Сr – V – Mo carbon-fluorine-containing additives and nickel can reduce signifi cant-ly the level of contamination of non-metallic oxide inclusions of weld metal, grinding grain; and it also reduces the volume fraction of retained austenite in the weld layer and the formation of small dispersed carbides. The results predict the increase of thermal stability of mill rolls when using the produced wire.
