Castings feem ntau muaj qhov tsis xws luag. Yuav ua li cas kom txo tau qhov poob?

Nyob rau hauv cov txheej txheem ntawm castings, vim muaj kev cuam tshuam ntawm ntau yam, qhov tsis xws luag xws li pores, pinholes, slag inclusions, tawg thiab pits feem ntau tshwm sim.

Lub sijhawm no, txhawm rau ua kom cov casting ua tau raws li tus qauv siv thiab txo qhov poob thiab pov tseg, qhov tsis xws luag feem ntau kho. Cov cuab yeej siv kho mob feem ntau yog argon arc vuam tshuab, tsis siv lub vuam tshuab, vuam tshuab txias, thiab lwm yam. Rau cov khoom siv hlau tsis zoo thiab cov yam ntxwv zoo, argon arc vuam tshuab thiab lwm yam vuam tshuab nrog cov cua sov tsim thiab kev kub ceev tuaj yeem siv rau. kho. Txawm li cas los xij, hauv kev kho qhov tsis xws luag ntawm precision castings, vim muaj kev cuam tshuam zoo ntawm argon vuam cua sov, qhov tsis xws luag xws li casting deformation, hardness txo, xuab zeb qhov, hauv zos annealing, tawg, pinhole, hnav, khawb, undercut, los yog tsis txaus. kev sib khi quab yuam thiab kev puas tsuaj sab hauv yuav tshwm sim thaum kho. Lub tshuab vuam txias tsuas yog kov yeej cov kev tsis zoo saum toj no. Nws qhov zoo yog feem ntau pom nyob rau hauv me me tshav kub cuam tshuam cheeb tsam, lub casting tsis xav tau preheating, thiab txias vuam kho ntawm ib txwm kub, yog li tsis muaj deformation, undercut thiab residual kev nyuaj siab, tsis muaj annealing hauv zos, thiab tsis muaj kev hloov nyob rau hauv cov hlau qauv. ntawm qhov casting.

Yog li ntawd, lub tshuab txias vuam yog tsim los kho qhov tsis xws luag ntawm precision castings. Kev kho qhov txias vuam yog: Φ 1. kho qhov tsis xws luag. Rau qhov tsis xws luag loj, daim ntawv thov kev sib xyaw ua ke ntawm cov txheej txheem vuam ib txwm siv thiab kev siv lub tshuab ua haujlwm tsis zoo raug pom zoo. Thaum xaiv lub tshuab vuam txias, nws tseem yuav tsum tau xaiv cov cuab yeej siv nrog qhov zoo ntawm kev ua haujlwm yooj yim, kev kho vuam zoo, siab ncej vuam lub zog, tua blasting tom qab vuam, thiab tsis poob tawm thaum lub sij hawm machining. Thaum xaiv lub tshuab txias txias no, tsis muaj qhov kho qhov yuav pom tom qab vuam, kho thiab polishing.
