Kev siv tshuab keeb kwm yav dhau los:
Kev lag luam tsheb thoob ntiaj teb tab tom txhim kho mus rau qhov hnyav sib dua, ceev dua, muaj kev nyab xeeb dua, txuag hluav taws xob dua, xis nyob dua thiab ua rau muaj kuab paug rau ib puag ncig. Yog li ntawd, kev siv cov khoom siv txhuas hauv tsheb nce ntxiv. Ua ib qho tseem ceeb ntawm lub kaw lus tsav tsheb, lub log hub kuj yog ib hom kev ruaj ntseg uas xav tau siab. Nws tsis tsuas yog dais qhov hnyav ntawm lub tsheb xwb, tab sis kuj qhia txog qhov zoo li ntawm lub tsheb. Hauv 10 xyoo dhau los, qhov nruab nrab txhua xyoo ntawm kev tsim khoom siv txhuas thoob ntiaj teb tau txog 7.6%.
Tam sim no, cov txheej txheem tsim cov log tsheb aluminium alloy hauv tsev thiab txawv teb chaws feem ntau muab faib ua ob pawg: ib qho yog forging, thiab lwm qhov yog casting. Txawm li cas los xij, qhov tsis zoo xws li qhov shrinkage, cov qauv xoob thiab cov qhov hauv cov khoom casting yog qhov loj heev, lub zog kho tshuab qis, thiab cov txiaj ntsig qis, uas tau dhau los ua qhov sib txawv ntawm kev tshem tawm.
Cov pwm forging ib txwm siv cov qauv sib xyaw, thiab txhua hom lub log hub yuav tsum sib xws rau ib khub pwm, yog li qhov chaw cia pwm, kev tswj hwm, kev saib xyuas thiab cov nqi tsim khoom loj heev, thiab cov pwm uas tau muab tso rau lub sijhawm ntev yooj yim heev rau kev puas tsuaj.
Thaum cov pwm qauv tag nrho raug puas tsuaj tom qab nias, cov pwm sab saud thiab qis dua yuav tsum tau hloov tag nrho, thiab tus nqi hloov pauv kuj loj heev, uas siv sijhawm ntau, siv sijhawm ntau thiab siv khoom ntau, uas ua rau tus nqi tsim khoom ntawm cov log tsheb aluminium alloy nce ntxiv thiab ua rau muaj kev pov tseg ntau ntawm cov peev txheej.
