Thawj lub ntsej muag: zinc alloy tuag casting yog raws li cov hlau tshaj, uas tau teev tseg. Zinc yog cov hlau tseem ceeb, thiab tom qab ntawd ib qhov nqi ntawm aluminium, magnesium thiab tooj liab yog ntxiv rau smelt zinc alloy ingot xav tau rau kev tsim khoom, uas yog lub hauv paus ntawm tsim nyog zinc alloy tuag casting.
Qhov thib ob lub ntsej muag: thaum cov khoom siv raw ntawm zinc alloy tuag casting xa rov qab rau hauv qhov cub tawg, qhov sib piv ntawm cov khoom nyoos tshiab thiab qub yuav tsum yog 7: 3, uas yog qhov zoo tshaj plaws thiab tuaj yeem txo cov txhuas siv thaum lub sij hawm rov qab los ntawm zinc alloy Cov.
Qhov thib peb yam: tom qab cov khoom tsim tau tsim, qhov kub ntawm cov khoom siv yaj nozzle yuav tsum tswj hwm tsis pub dhau 430 ℃. Zam kom tsis txhob poob zoo ntawm cov hlau thaum kub. Tseem muaj cov tshuab electroplating tom qab kev tsim khoom uas tuaj yeem muab tso ua ke rau hauv qhov cub ua kom rov ua dua tshiab.
Qhov thib plaub yam: tag nrho cov tuag casting factories yuav tsum mloog zoo lawv cov kev ua haujlwm thiab yaj zinc alloy ingots hauv tib lub cub tawg. Nyob rau hauv txoj kev no, tsis tsuas yog tus nqi ntawm melting tuaj yeem txo, tab sis kuj tseem muaj qhov flux tuaj yeem siv rau qhov siab tshaj plaws los xyuas kom meej tias txhua txoj kev ua haujlwm tau raug.
Fifthly, tus nqi ntawm zinc alloy tuag-casting yuav tsum tsis txhob muab ntxiv. Peb yuav tsum xyuam xim khaws cia hauv cov khoom cua uas tsis muaj qhov cua, tsis noo, huv. Peb tseem yuav tsum nruj tswj hwm cov ntaub ntawv khaws cia hauv cov kab ntawv kom tiv thaiv impurities.
