Seamless steel kav dej siv dav hauv ntau cov tshuab kev tsim kho tshuab, yog li cas lawv tsim? Hnub no yuav coj koj mus kom nkag siab txog cov txheej txheem ntau lawm ntawm cov yeeb nkab seamless steel.
1. Txo cov dov thiab sizing dov
Txawm hais tias tsis muaj kev txhim kho txuj ci tsim nyog ntawm kev taw qhia tshwj xeeb hauv kev txo cov ntxuag thiab sizing dov rau kev kho zaum kawg ntawm sab hauv lub cheeb, ntau lub taub loj sizing tshuab kuj siv peb-yob sizing tshuab. Qhov tsis zoo ntawm kev siv peb yob yog tias lub yob yob tsis tuaj yeem hloov pauv tau, yog li muaj ntau yam racks, tab sis tsis ntev los no tseem muaj qhov sib txawv txav yob suab yob yob, thiab lub tswv yim ntawm plaub-yob reducer tau npaj siab. Nyob rau hauv lub neej yav tom ntej, kev siv tshuab ncaj qha ntawm lub tshuab mandrel seamless tube dov lub cav, lub tshuab sizing thiab lub nro rub tawm tseem yuav nyiam cov neeg' s mloog. Kev txhim kho ntawm qhov hais los saum toj-qib high-alloy tho me me hauv cov teb ntawm cov kav hlau thiab txoj kev txhim kho ntawm mandrel phau ntawv qhia kev sib tsoo thiab billet tshuab roj muaj feem cuam tshuam nrog kev tsim thev naus laus zis. Nws cia siab tias lub thev naus laus zis technology yuav raug tsim kho ntxiv.
2. Ncab ncaj
Lub mandrel-hom seamless raj dov zeb tau raug tsim nyob rau hauv cov kev coj ntawm loj-loj thiab compact. Tus naj npawb ntawm sawv ntsug yog txo los ntawm 7-9 poob mus rau 4-5 pawg, thiab lub zog noj ntawm cov tho qhov tshuab thiab mandrel seamless steel yeeb nkab dov tuaj yeem raug txo li 20%. Hauv lub mandrel seamless tube rolling zeb tswj kev siv tshuab, txhawm rau kom txo qhov txiav txuas ntawm lub raj kawg phab ntsa tuab hauv qhov nro reducer, lub raj kawg ua ntej-thinning txoj kev tsim tshuab tau tsim, uas yog, lub mandrel seamless tube dov zeb tube kawg uantej-thinning txoj kev siv tshuab thev naus laus zis, cov hlau yeeb yob rolling zeb adopts roj siab txo cov ntaus ntawv thawj zaug.
3. Stamping thiab dov
PPM (siab yob punching tshuab) uas siv cov ntawv xov xwm square tau hloov los ntawm kab pheeb ces kaum yob xuas nrig ntaus tshuab uas siv ntau daim billets. Qhov kom zoo dua ntawm lub tshuab conical tho lub cav yog tias nws muaj qhov sib txuam forging, muaj peev xwm tshem tawm cov txheej txheem tsis muaj txheej txheem shear, thiab yog li tuaj yeem tshem qhov tsis xws luag ntawm sab hauv ntawm cov yeeb nkab steel, thiab tuaj yeem siv rau cov khoom siv rau cov txheej txheem nyuaj, tshwj xeeb reaming thiab nyias-phab ntsa tho. Thaum siv cov tho qhov zoo tib yam ntawm lub tshuab, qhov txwv ntawm phab ntsa / qhov taub ntawm qhov sib piv sib piv (T / D) yog kwv yees li 6%, thaum siv lub tshuab conical tho kev siv tshuab, thin-walled hlab nrog T / D ntawm 3.2% tuaj yeem raug chob Cov.
