Melting ntawm malleable steel yeeb nkab fittings thiab castings

Smelting yog ib qho tseem ceeb ntawm kev tsim cov hlau castings. Qhov zoo ntawm cov hlau castings nyob ntawm qhov loj ntawm qhov zoo ntawm cov hlau molten. High-quality molten hlau yuav tsum ua raws li cov hauv qab no

Cov cai hauv qab no:

(1) Cov tshuaj muaj pes tsawg leeg ua tau raws li qhov yuav tsum tau ua thiab cov khoom muaj nyob ruaj khov;

(2) Qhov kub thiab txias txias yog qhov tsim nyog;

(3) Cov ntsiab lus ntawm cov pa oxygen, nitrogen, hydrogen thiab qee cov khoom siv microscopic yog nyob rau hauv kev tswj xyuas; .

(4) Cov ntsiab lus tsawg ntawm qhov nyuaj rau kev sib cais thiab kev suav nrog theem nrab.

Cam khwb cia hlau smelting tsis yog tsuas yog ib txoj kev melting xwb. Cov txheej txheem no muaj qee qhov kev cuam tshuam metallurgical thiab cuam tshuam los ntawm ntau yam hauv ob qho tib si metallurgical thermodynamics thiab kinetics. Yog li ntawd, peb yuav tsum sim siv ntau yam txuj ci los tswj kev cuam tshuam ntawm ntau yam metallurgical yam thiab ua rau lawv lub zog tsav rau kev tsim cov hlau molten zoo.

Kev siv ntawm malleable steel yeeb nkab fittings rau casting loj

Cov castings uas tsim los ntawm qhov tsis zoo siab cov khoom casting tsis txwv los ntawm qhov loj ntawm cov hlau nplaum sib nqus zoo li cov hlau nplaum casting. Ntev npaum li qhov loj ntawm tus ncej hlau nplaum yog tsau, qhov loj ntawm lub thawv xuab zeb tseem raug kho. Nws yog yuav luag tsis yooj yim sua rau cam khwb cia castings uas tshaj qhov loj ntawm lub thawv xuab zeb. Yog, nws yog feem ntau tsuas yog haum rau pouring me me pieces ntawm ib puas thiab kaum kilograms. Tsis zoo-siab cov khoom indium casting yog ntau ntxiv rau qhov loj ntawm castings. Cov thawv xuab zeb ntawm ntau qhov sib txawv tuaj yeem muab tso rau ntawm tib lub rooj vibrating, yog li castings ntawm ntau qhov ntau thiab tsawg tuaj yeem tsim tau yooj yim heev.

Txawm li cas los xij, vim qhov tsis tshua muaj zog ntawm cov qauv yas ua npuas ncauj thiab qhov tseeb tias cov khoom ntim tsis tuaj yeem tsis sib xws thaum lub sijhawm ua haujlwm, cov qauv yooj yim deformed, uas ua rau muaj qee yam teeb meem rau casting loj, nqaim thiab nyias. Yog li ntawd, xav txog qhov yooj yim ntawm kev lag luam thiab cov thev naus laus zis uas twb muaj lawm, qhov tsis zoo siab compact casting yog tsim rau castings nrog castings hauv qab 2t (tshwj xeeb tshaj yog 500kg) thiab nrog phab ntsa thickness ntau dua 4 hli.

Kev ua haujlwm thiab cov qauv dav dav ntawm lub cev valve ntawm malleable steel yeeb nkab fittings

Lub cev valve yog qhov tseem ceeb tshaj plaws uas ua rau lub siab, kub, yaig thiab corrosion ntawm qhov nruab nrab ua haujlwm. Nyob rau tib lub sijhawm, kev thauj khoom ntxiv xws li deformation thiab kev co ntawm cov kav dej vim thermal expansion thiab contraction yuav cuam tshuam rau kev nyab xeeb ntawm lub cev valve. Yog li ntawd, qhov tsim ntawm lub valve lub cev yuav tsum ua raws li cov hauv qab no:

(1) Txiav txim siab cov khoom tsim nyog raws li qhov ua haujlwm nruab nrab kom ntseeg tau tias cov khoom muaj kev tiv thaiv corrosion zoo thiab muaj qee lub zog thiab toughness;

(2) Txiav txim siab txoj kev tsim khoom thiab cov qauv tsim ntawm lub valve lub cev raws li kev tsim tag nrho, kev xav tau ntawm cov khoom siv thiab kev ua haujlwm ntawm lub valve;

(3) Muab xam thiab txiav txim siab qhov tsawg kawg nkaus phab ntsa thickness ntawm lub valve lub cev, thiab coj mus rau hauv tus account cov txheej txheem tsim yuav tsum tau ntawm lub valve lub cev thiab qhov tsim nyog corrosion pub, thiab thaum kawg txiav txim siab ib tug tsim nyog valve lub cev loj.

Stainless hlau valve lub cev-phom muaj ntau yam txheej txheem xws li casting qauv, forging qauv, cam khwb cia-welding qauv, forging-welding qauv thiab yeeb-vuam qauv.

Cov yam ntxwv ntawm cov qauv casting yog cov qauv tsim nyog, kev hloov pauv ntawm qhov ntws ntws, cov kua dej me me, cov khoom siv siab siv, thiab tsawg dua machining workload. Txawm li cas los xij, qhov zoo ntawm qhov chaw yog ntxhib, uas ua rau muaj teeb meem sab hauv zoo, yog li nws feem ntau haum rau cov txheej txheem dav dav ntawm cov kav dej nruab nrab thiab qis.

Qhov kom zoo dua ntawm cov qauv forged yog tias nws tsis txwv los ntawm kev ua haujlwm siab, thiab cov kab noj hniav sab hauv thiab kev ncig ntawm lub valve yog tag nrho ua tiav los ntawm kev ua haujlwm, yog li qhov zoo ntawm qhov chaw yog qhov zoo tagnrho, thiab nws tau siv dav hauv cov kav dej siab, cov khoom siv hluav taws xob qub thiab ntau lub zog. Nws qhov tsis zoo yog qhov poob ntawm cov hlau loj, thiab cov khoom siv machining yog qhov loj.
