Raws li kev sib txuas tseem ceeb txuas hauv kev lag luam niaj hnub, cov txheej txheem ntau lawm ntawm cov tshuab kho tshuab tau nyiam ntau.
Qhov thib ib yog cov khoom xaiv thiab pretrastment theem. Raws li cov haujlwm ua haujlwm thiab kev ua tau zoo, muaj zog, muaj zog-resistant thiab corrosion-resistant steel lossis stainless hlau feem ntau raug xaiv. Tom qab xaiv cov khoom siv, cov txheej txheem kho cua sov xws li annealing thiab no yuav tsum tau nqa tawm los txhim kho cov qauv sab hauv ntawm cov khoom thiab txhim kho nws cov khoom siv tshuab thiab kev ua haujlwm.
Tom qab ntawd nkag mus rau cov txheej txheem moulding. Kev Foob cov txheej txheem tuaj yeem tshem tawm sab hauv kev puas zoo tsis xws luag thiab lub zog tswj, tab sis nws yuav tsum tau kho kom ntsuas qhov ntsuas kub xws li kub, siab thiab lub sijhawm. Cov txheej txheem casting yog haum rau huab hwm coj ntau lawm thiab tuaj yeem tsim cov tes tsho sib txawv ntawm ib lub sijhawm, tab sis nws yog qhov tsim nyog los tiv thaiv tsis xws li shrinkage qhov thiab cov kab nrib pleb.
Tom qab molding, lub tes tsho expansion yuav tsum yog lub ntsej muag zoo nkauj, suav nrog tig mus sab hauv thiab sab nraud ntawm lub ntsej muag, drilling thiab chamfering. Cov txheej txheem no yuav tsum siv cov cuab yeej siv tshuab siab thiab cov cuab yeej siv nruj thiab nruj tswj cov khoom tsis muaj tseeb kom paub tseeb tias qhov tsim nyog los ntawm tus qauv tsim tiav.
Txhawm rau txhim kho cov hnav tsis kam thiab corrosion tsis kam ntawm lub tes tsho expansion, kev kho deg thiab kev tiv thaiv. Cov kev sib xws muaj cov electroplating, txau thiab tshuaj plating. Cov ntawv thov tshwj xeeb kuj tseem xav tau kev kho cua sov, carburizing thiab lwm yam kev tiv thaiv.
Tom qab machining thiab nto kev kho mob, lub tes tsho extransion yog ntsuas kom pom tseeb thiab muab piv nrog cov qauv tsim, thiab hloov pauv hloov pauv hauv lub sijhawm.
Qhov no yog ua raws li kev sim tshuaj thiab pov thawj. Los ntawm cov kev ntsuam xyuas Tensile, cov kev kuaj compression, ntsuam xyuas siab, thiab lwm yam, kev ntseeg tau thiab ua tau zoo raws li cov kev ua haujlwm tiag tiag yog sim.
Thaum kawg, tom qab tag nrho cov txheej txheem thiab kev pom zoo ntawm kev tsim nyog, lub tes tsho extransion yuav tau ntim thiab xa cov ntawv pov thawj khoom thiab cov ntawv qhia cov khoom lag luam thiab phau ntawv qhia ntawv.
