Nrog rau kev txhim kho kev lag luam tsim, Tuag castastings, raws li tseem ceeb cov khoom siv, tau txais nce ntxiv thiab thov. Txawm li cas los xij, yog tias cia thiab tu tsis yog tswj tau kom tsim nyog thaum lub sijhawm tuag casting ntau lawm txheej txheem, cov khoom lag luam tau yooj yim yooj yim. Yog li, yuav ua li cas yuav tuag casting casting?
1. Cia kub thiab av noo
Qhov chaw cia kub rau cov tuag castings yuav tsum yog nruab nrab ntawm 5℃thiab 35 degree, thiab cov av noo yuav tsum nyob nruab nrab ntawm 40% thiab 60%. Yog tias qhov ntsuas kub siab dhau, saum npoo ntawm cov tuag casting yog nquag mus rau oxidation thiab xeb, cuam tshuam rau cov khoom lag luam zoo; Yog tias qhov ntsuas kub tsawg dhau, nws tuaj yeem coj los deformation thiab tawv tawv. Yog hais tias cov av noo siab dhau, kev tuag casting yog qhov sib nqus noo noo noo noo noo thiab xeb, ua rau cov khawb npoo thiab passivation; Yog tias cov av noo qis dhau, saum npoo ntawm cov tuag casting yuav hmoov thiab tawg, cuam tshuam nws lub neej pabcuam.
2. Txwv kev ntsuas xeb
Thaum lub sijhawm cia, tuag castingings yuav tsum tau kho nrog xeb tiv thaiv kom ntseeg tau tias cov khoom lag luam zoo nkauj thiab nws lub neej pabcuam. Cov hau kev suav nrog txau cov roj, thov roj, thiab ntim khoom. Ntawm cov no, txau muaj kev tiv thaiv muaj xeb zoo tab sis ua rau ib puag ncig ib puag ncig kev muaj kuab paug; Ua ntawv thov cov roj tuaj yeem yooj yim tsim cov pos - zoo li cov tshuaj rau ntawm txheej, ua rau muaj qhov chaw tsis sib xws; thiab ntim khoom yuav tsum xaiv cov ntaub ntawv tiv thaiv uas tsim nyog thiab kev ua yeeb yam.
3. Zam kev ya raws
Tuag -}}}} nrum seem yog nquag rau xeb thaum lub sijhawm cia, cuam tshuam rau cov khoom lag luam zoo. Yog li ntawd, ib qhuav, zoo - cua tshuab cov chaw cia khoom yog qhov tsim nyog. Ua ntej cia, cov khoom lag luam nto yuav tsum tau muab ntxuav thiab cov ntaub so, nrog kev saib xyuas them rau cov dej noo thiab hmoov av. Yog tias nws tau txais cov ntxeem tau, nws yuav tsum tau ntxuav thiab ziab kom sai.
4. Zam kev kub thiab zaws
Tuag -}}}} nrum seem yuav tsum tseem muaj kev tiv thaiv los ntawm tshav kub thiab nias thaum lub sijhawm khaws cia. Lub sijhawm ntev tau ua rau muaj kev kub ntxhov yuav ua rau muaj kev cuam tshuam thiab kev sib cav sib ceg; Compression tuaj yeem ua rau cov khoom puas tsuaj rau cov khoom lag luam thiab qauv sab hauv, cuam tshuam rau kev ua tau zoo. Yog li ntawd, ib qho chaw cia khoom tiaj yuav tsum tau xaiv, zam kev compression thiab cuam tshuam kom ntau li ntau tau.
