Cov txheej txheem kev ua haujlwm ntawm cov hlau stainless hlau precision casting.

Cov khoom siv dag zog ntawm stainless hlau precision casting muaj ntau dua li cov hlau cam khwb cia, tiam sis nws qhov kev ua yeeb yam yog tsawg dua li ntawm cov hlau cam, uas belongs rau precision casting los yog precision casting. Nws lub txiaj ntsim zoo dua, cov kua hlau yog yooj yim rau oxidize, cov dej ntawm cov dej yog cov neeg pluag, shrinkage loj, cov hlau stainless precision casting tsis tsuas siv rau ntau hom, ntau yam alloy casting.

Txheeb xyuas cov yam ntxwv ntawm stainless hlau precision casting:

1, vim tias cov hlau tsis ruaj khov casting shrinkage considerably ntau tshaj hlau cam, tiv thaiv casting shrinkage kab noj hniav, shrinkage defects, siv riser thiab feem ntau ntawm casting txheej txheem, txias hlau thiab subsidies thiab lwm yam kev ntsuas, kom paub cov solidification sib lawv liag.

Kev tiv thaiv cov hlau tsis sib haum xeeb, ntsws kab ntswj, ntsws, porosity thiab tawg tsis xws li, yuav tsum ua kom nws lub cev tsis zoo, tsis txhob ntse pob thiab ncej, sawdust ntxiv rau pwm nrog xuab zeb, ntxiv coke mus rau tub ntxhais, thiab cov tub ntxhais hollow thiab xuab zeb core thiab thiaj li los txhim kho cov xuab zeb pwm los yog cov tub ntxhais kawm ntawm cov pa thiab rov qab.

2. Vim lub pluag liquidity ntawm cov kua hlau, lub phab ntsa ntawm cov hlau cam yuav tsum tsis pub tsawg dua 8 hli los tiv thaiv cov hlau casting ntawm txias thiab tsis txaus. Qhuav cam khwb cia lossis kub; Ntsig zuj zus ncuav kub, nruab nrab ntawm 1520 ° ~ 1600 ℃, vim yog lub siab kub hnyiab, ua kua ua kua, ua kom ntev, kua tau zoo dua. Txawm li cas los xij, qhov kub siab dhau lawm, uas tuaj yeem ua rau muaj qhov tsis xws luag xws li coarse grain, kub nplaum, stoma thiab xuab zeb. Yog li feem ntau me me, thin phab ntsa thiab cov duab zoo meej precision castings, lub thawv kub yog hais txog cov pa kub melting ntsuas kub ntawm + 150 ℃; Tus qauv ntawm cov txheej txheem pouring yog yooj yim thiab seem loj yog loj tshaj qhov uas raug pov tseg hlau. Loj, tuab phab ntsa casting pouring kub txog 100 ℃ siab tshaj qhov taw tes rau lub cev.
