Theoretical tsom xam ntawm casting txoj kev xws li hlau castings

Txoj kev xav ntawm kev tsim casting: Hlau ua kua yog feem ntau hu ua casting, thiab casting txoj kev siv tshuab muaj keeb kwm ntev. Thaum ntxov li 5,000 xyoo dhau los, peb cov poj koob yawm txwv tuaj yeem ua cov khoom siv tooj liab liab thiab tooj liab. Casting yog txoj kev siv hlau ua kua ntau tshaj plaws. Nws yog ib txoj hauv kev ntawm cov kua hlau tso rau hauv cov pwm kab noj hniav, thiab tom qab ntawd tau txais qee yam duab ntawm qhov khoob khoob los yog qhov chaw tom qab txias thiab khov. Qhov kev faib ua feem ntawm cov kua forming castings nyob rau hauv machinery thiab cov cuab yeej yog loj, thiab cov kua tsim qhov chaw account rau 70% mus rau 9{13}}% ntawm tag nrho cov hnyav nyob rau hauv lub tshuab cuab yeej, internal combustion engine, mining machinery thiab tshuab hnyav. 50% ~ 70% hauv tsheb thiab tsheb laij teb; Nws suav txog 40% txog 70% ntawm cov tshuab ua liaj ua teb. Cov txheej txheem ua kua tuaj yeem siv dav vim tias nws muaj cov txiaj ntsig zoo hauv qab no: nws tuaj yeem tsim cov castings dawb nrog cov kab noj hniav nyuaj heev. Xws li ntau lub thawv castings, tshuab cuab yeej castings, lub tog raj kheej castings, lub tog raj kheej taub hau castings, thiab lwm yam.; Casting txheej txheem yooj, dav adaptability. Qhov loj ntawm cov kua tsim castings yog yuav luag tsis txwv, nws qhov hnyav tuaj yeem yog los ntawm ob peb grams mus rau ntau pua tons, thiab nws cov phab ntsa tuab tuaj yeem yog los ntawm 0.5mm txog 1m. Txhua yam khoom siv hlau uas tuaj yeem yaj ua kua hauv kev lag luam tuaj yeem siv los ua kua. Rau cam khwb cia hlau nrog cov yas tsis zoo, ua kua yog qhov zoo tshaj plaws los tsim nws qhov khoob lossis qhov chaw. (3) Tus nqi ntawm cov khoom ua kua yog tsawg. Kev tsim cov kua dej tuaj yeem siv ncaj qha siv cov khoom pov tseg thiab cov chips, thiab cov khoom siv raug nqi tsawg. Nyob rau tib lub sijhawm, kev ua haujlwm pub dawb ntawm cov kua ua cov castings yog me me, txuag hlau. Txawm li cas los xij, cov txheej txheem ntawm cov hlau ua kua yog ntau, thiab nws yog ib qho nyuaj rau kev tswj kom raug, uas ua rau qhov zoo ntawm casting tsis ruaj khov txaus. Piv nrog rau cov wrought qhov chaw ntawm tib cov khoom, qhov tsis xws luag xws li shrinkage qhov, porosity thiab porosity yog ib qho yooj yim tshwm sim nyob rau hauv vim lub xoob qauv thiab coarse grain ntawm kua tsim. Nws cov khoom siv kho tshuab muaj tsawg. Tsis tas li ntawd, kev siv zog ua haujlwm loj thiab cov xwm txheej tsis zoo. Casting muaj cov khoom siv zoo heev thiab lub cev, nws tuaj yeem muaj ntau yam sib txawv ntawm lub zog, hardness, toughness nrog kev ua tau zoo, tab sis kuj tuaj yeem muaj ib lossis ntau yam khoom tshwj xeeb, xws li hnav tsis kam, siab thiab kub tsis kam, corrosion kuj. Qhov hnyav thiab qhov loj ntawm cov castings yog qhov dav heev, qhov hnyav tsuas yog ob peb grams, qhov hnyav tuaj yeem ncav cuag 400 tons, phab ntsa thickness tsuas yog 0.5 hli, thickness tuaj yeem tshaj 1 meter, thiab qhov ntev tuaj yeem yog los ntawm ob peb millimeters. mus rau ntau tshaj 10 meters, uas muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm txawv industrial sectors.

Pebhnub nyoog

Kev siv cov castings yog dav heev, tau siv nyob rau hauv kho vajtse thiab tag nrho cov tshuab thiab hluav taws xob kev lag luam, thiab nws siv tau dhau los ua ib qho kev nthuav dav. Tshwj xeeb yog siv rau hauv kev tsim kho, kho vajtse, khoom siv, kev tsim kho tshuab thiab lwm yam khoom siv loj, cov cuab yeej siv tshuab, nkoj, aerospace, tsheb, locomotives, electronics, computers, khoom siv hluav taws xob, teeb thiab lwm yam lag luam, ntau yam yog tib neeg txhua hnub kev sib cuag, tab sis ua tsis nkag siab txog cov khoom siv hlau.

Peb lub Hoobkas tsuas yog tsim txhua yam ntawm nodular castings, grey hlau castings, alloy castings, twj plhaub, impeller skeleton thiab lwm yam castings.
