发明名称 METHOD OF CONSUMABLE ELECTRODE PRODUCTION FROM METAL CHIPS
摘要 FIELD: metallurgical processing of wastes, mainly, in the form of chips from titanium alloys to produce consumable electrodes in production of secondary titanium alloys and in steel alloying. SUBSTANCE: method includes crushing and cleaning of chips, vacuum thermal degassing at 550-650 C with holding ay said temperature for 1-2 h. Chip briquettes are pressed and loaded into mold with clearance. Mold before filling with the same alloy is heated up to 400-450 C. Invention provides for utilization of 100% of ships in production of casting alloys, exclusion of expensive titanium sponge from process of manufacture of consumable electrodes, increased mechanical strength of electrodes and improved quality of secondary alloys due to reduction of impurities content. EFFECT: higher efficiency. 5 cl, 2 tbl, ex
