FLUX CORED WIRE Russian patent published in 2019 - IPC B23K35/36 B23K35/368 

FIELD: metallurgy.

SUBSTANCE: invention can be used for surfacing the working surfaces of parts of metallurgical equipment, which are subject to increased requirements for hardness and wear resistance. Charge of the flux cored wire contains the following components in the following ratio, wt. %: gas cleaning dust from production of ferrochromium 52–82 and dust of electrostatic precipitators of aluminium production 18–48. Introduction to composition of powder gas dust mixture of gas purification of ferrochrome production allows to carry out reduction of chromium from oxides contained in dust of gas purification of ferrochromium production, with carbon contained in dust of gas purification of aluminium production.

EFFECT: charge provides for obtaining deposited chromium-containing metal of high wear resistance and enables to recycle wastes with production of demanded material.
