Alloy smelting yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev siab los yog inert gas (ar los yog ne) tiv thaiv. Cov crucibles siv rau smelting tag nrho siv dej txias tooj liab crucibles. Muaj peb txoj hauv kev tseem ceeb ntawm cov txheej txheem smelting tshwj xeeb:
(1) Tsis siv neeg electrode hluav taws xob arc rauv melting. Alloy melting yog nqa tawm nyob rau hauv lub tshuab nqus tsev los yog inert gas tiv thaiv. Cov txheej txheem no tsuas yog npaj cov electrodes los ntawm smelting consumable electrodes.
(2) Lub tshuab nqus tsev siv hluav taws xob hluav taws xob arc rauv smelting siv cov khoom siv hluav taws xob ua los ntawm titanium lossis titanium alloy ua cov cathode, thiab cov dej-txias tooj liab crucible li cov anode. Lub molten electrode nkag mus rau hauv lub crucible nyob rau hauv daim ntawv ntawm cov tee dej, tsim ib tug molten pas dej ua ke. Qhov saum npoo ntawm lub pas dej molten yog rhuab los ntawm arc thiab yog ib txwm nyob rau hauv lub xeev ua kua. Cov cheeb tsam ib puag ncig qhov twg hauv qab thiab cov crucible nyob rau hauv kev sib cuag raug yuam kom txias, ua rau hauv qab-up crystallization. Cov hlau molten nyob rau hauv lub pas dej molten solidifies rau hauv titanium ingots.
(3) Nqus consumable electrode plhaub tiv thaiv melting. Schematic ntawm lub melting ntaus ntawv. Lub tshuab hluav taws xob no yog tsim los ntawm lub tshuab nqus tsev siv hluav taws xob hluav taws xob hluav taws xob arc rauv. Nws yog hom rauv rau casting tshwj xeeb-puab qhov chaw uas sib txuas smelting thiab centrifugal pouring. Nws qhov tseem ceeb tshaj plaws yog tias muaj lub plhaub nyias ntawm titanium alloy ntawm cov dej-txias tooj liab crucible thiab cov hlau yaj, uas yog hu ua condensation plhaub. Cov txheej txheej ntawm lub plhaub ntawm cov khoom siv tib yam ua haujlwm li hauv ob sab phlu ntawm lub crucible los tsim ib lub pas dej molten los khaws cov kua titanium. , kom tsis txhob muaj kab mob ntawm cov titanium alloy kua los ntawm lub crucible. Tom qab pouring, ib txheej ntawm condensation plhaub sab laug nyob rau hauv lub poob yuav siv tau raws li ib tug crucible hauv ob sab phlu.
