Khoom Taw qhia ntawm Tuag Castings
Tuag castings yog cov khoom hlau tsim los ntawm kev siv cov txheej txheem siab casting. Kuj tseem hu ua tuag- nrum qhov chaw lossis siab castings, lawv feem ntau yog tsim los ntawm cov khoom siv xws li tooj liab, zinc, txhuas, thiab txhuas alloys. Cov txheej txheem no siv lub zog siab los txhaj cov hlau molten rau hauv pwm kom nrawm nrawm, ua rau muaj kev ua haujlwm siab, zoo nto tiav, thiab cov nyiaj siv me me. Tus tsim yuav tsum xav txog yam xws li phab ntsa thickness, casting fillets, thiab cov kaum sab xis.
Raws li cov khoom siv, cov tshuab tuag casting tuaj yeem muab faib ua cov tshuab kub kub tuag casting tshuab (tsim rau zinc thiab magnesium alloys) thiab txias chamber tuag casting tshuab (tsim rau txhuas thiab tooj liab alloys). Nyob rau hauv kub chamber tuag casting tshuab, lub txhaj tshuaj yog immersed nyob rau hauv molten hlau.
Tuag castings yog dav siv nyob rau hauv automotive qhov chaw, cav kav, motor kawg caps, thiab lwm yam teb. High- tshuab nqus tsev tuag casting tshuab tuaj yeem txo qhov porosity thiab txhim kho weldability thiab kev kho cua sov, ua lub luag haujlwm tseem ceeb hauv kev sib xyaw tuag casting ntawm lub zog tshiab.
Kev kub siab casting siv 15-100MPa siab los txhaj rau hauv pwm, thiab thinnest aluminium alloy phab ntsa tuaj yeem ua nyias li 0.5mm, uas yog tsim rau cov khoom xws li lub tog raj kheej cav; lub tshuab nqus tsev tuag casting txhim kho qhov ntom ntom los ntawm kev tshem tawm cov huab cua los ntawm cov kab noj hniav, thiab txawm hais tias cov khoom siv raug nqi ntau dua, cov txiaj ntsig ntev yog qhov tseem ceeb.
