Dab tsi yog cov khoom siv thev naus laus zis?
Tin Ingot ua thev naus laus zis hais txog cov txheej txheem kev ua tiav rau cov khoom qub Tawb los ua tiav cov khoom lag luam ntawm cov khoom lag luam tiav ntawm cov khoom lag luam ua tiav thiab cov duab. The tin ingot processing technology usually includes a series of process steps such as material preparation, smelting, casting, forging, rolling, stretching and annealing.

Ua ntej, npaj npaj yuav tsum tau xaiv cov hmoov nplej siab zoo ua kom ntseeg tau tias lawv muaj pes tsawg leeg thiab ua tau zoo raws li qhov yuav tsum tau ua. Tom qab ntawd cov txheej txheem smelting yog nqa tawm mus rau tshav kub thiab yaj tus thawj ingots kom tshem tawm impurities thiab oxides kom ntseeg tau qhov kev coj dawb huv thiab kev ua tau zoo ntawm molten tin.
Tom ntej no yog cov txheej txheem casting, uas cov molten tin kua yog hliv rau hauv cov pwm rau molding los ua cov khoom siv ntau yam thiab cov duab. Tom qab ntawd cov txheej txheem Forging yog nqa tawm los deform rau cov tin billet los ntawm kev siv tshuab thiab cuam tshuam yuam kom muaj zog thiab cov khoom siv kho txhua yam ntawm nws cov khoom.
Tom qab ntawd los cov txheej txheem dov, nyob rau hauv uas cov forged Tin billet yog dov qhov yuav tsum tau tuab thiab dav, thaum txhim kho nws lub ntsej muag tiav thiab tiaj. Tom qab ntawd los tus txheej txheem ncab, uas lub tin billet tau ua rau hauv ntau cov khoom lag luam, Tin cov xov hlau thiab cov duab los ntawm kev ncab quab yuam.
Thaum kawg, cov txheej txheem annealing yog nqa tawm mus rau anneal cov txheej txheem Tin daim hlau, Tin cov kav hlau thiab lwm yam khoom kom tau txais kev ntxhov siab thiab deformation ntawm cov khoom.
Feem ntau, cov txheej txheem ingot tin yog qhov ua kom muaj ntau cov txheej txheem thiab kev tswj hwm nruj ua tiav rau cov khoom tiav ntawm cov khoom tiav ntawm cov khoom tiav ntawm cov khoom lag luam ua tiav ntawm cov khoom lag luam ua tiav ntawm cov khoom tiav ntawm cov khoom tiav ntawm cov khoom lag luam ua tiav Cov khoom tiav tiav no tau siv dav hauv cov khoom siv hluav taws xob, tshuaj, kev tsim kho, kev tsim kho, thiab lwm daim teb thiab muaj cov nyiaj txiag tseem ceeb thiab muaj txiaj ntsig.
