Flux-cored wire for surfacing parts subject to high abrasive wear

摘要

The utility model relates to the field of electric arc surfacing with flux-cored wire of parts subject to high abrasive wear under moderate shock loads, for example, blades and rolls of grinding mills, working surfaces of exhausters, chutes, protective plates forming the surfaces of bowls and cones of blast furnaces and other parts operating under temperatures up to 300 ° C. The utility model can be used in metallurgy and other industries. The technical problem to be solved by this utility model is to increase the operational properties of the deposited metal, in particular, wear resistance by optimizing the chemical composition of the powder filler. abrasive wear, consists of a steel shell and a powdery filler containing the following ratio of components, wt. %: carbon 0.5-1.5; manganese 0.5-2.0; silicon ≤1.2; phosphorus ≤ 0.025; sulfur ≤0.025; chromium 13.0-23.0; titanium 0.1-0.6; boron 2.2-3.6; iron and impurities are the rest. 1 s.p. f-ly, 2 tab.
