Feem ntau siv cov blanks rau kev siv tshuab xws li castings, forgings, profiles, thiab welded qhov chaw. Qhov sib txawv ntawm cov blanks thiab qhov tseeb, roughness, thiab hardness ntawm cov blanks muaj qhov cuam tshuam ncaj qha rau cov txheej txheem kev siv tshuab.
Thaum xaiv valve blanks, cov hauv qab no yuav tsum tau xav txog:
(1) Cov khoom siv ntawm cov khoom thiab cov kev xav tau rau cov khoom siv thiab kev ua haujlwm: Cov khoom siv tau teev nyob rau ntawm daim duab tsim feem ntau txiav txim siab seb hom khoob. Piv txwv li, yog hais tias cov khoom tivthaiv yog cam khwb cia hlau, txoj kev casting yuav tsum tau siv los tsim cov dawb paug. Rau cov khoom steel, cov khoom siv kho tshuab yuav tsum tau xav txog thaum xaiv qhov khoob. Piv txwv li, qhov chaw rau kev tsim cov siab siab li qub feem ntau yuav tsum tau ua los ntawm forgings lossis welded qhov chaw kom ntau li ntau tau los xyuas kom meej tias cov khoom muaj cov khoom zoo.
⑵ Cov qauv tsim thiab qhov loj me ntawm qhov chaw: Cov qauv ntawm cov khoom yog qhov tseem ceeb cuam tshuam rau kev xaiv ntawm qhov khoob. Piv txwv li, rau lub cev lub cev nrog cov qauv txheej txheem nyuaj, castings yuav tsum tau xaiv ntau li ntau tau. Lub cev lub cev loj tuaj yeem muab pov rau hauv cov xuab zeb pwm; Rau qhov me me, peev casting yog siv.
⑶ Qhov loj ntawm qhov kev pab cuam ntau lawm: Qhov loj dua qhov kev tsim khoom ntawm cov khoom, qhov zoo dua ntawm kev lag luam ntawm kev siv high-precision thiab high-efficiency blank manufacturing txoj kev.
(4) Cov xwm txheej rau kev tsim khoom dawb: Kev xaiv ntawm qhov khoob yuav tsum ua raws li cov khoom siv ntawm qhov chaw thiab cov txheej txheem, thiab qhov kev cia siab yuav tsum raug txiav txim siab. Advanced blank manufacturing txoj kev yuav tsum maj mam saws
