Kev tsim thiab sizing ntawm seamless kav, qee qhov kev tsim thiab kev hloov kho yuav cuam tshuam ncaj qha rau qhov zoo, yog li peb yuav tsum tau ua tib zoo saib rau yim lub ntsiab lus hauv qab no thaum tuav txoj kev tsim cov kav dej seamless:

1. Ua ntej tsis muaj qhov perforation, lub qhov zoo ntawm txhua lub khib yuav tsum tau kho, thiab qhov loj ntawm txhua qhov hla yuav tsum tau ntsuas kom ntseeg tau tias cov yeeb nkab steel seamless nkag mus rau txhua lub khib nyiab. Hauv kev hloov kho, lub zog yuav tsum sib npaug, thiab nws yuav tsum tsis txhob raug yuam kom deform rau ntawm ib lub thav duab, thiaj li ua kom ruaj khov thiab zoo ib yam hloov ntawm lub kaum sab xis;

2. Cov txheej txheem yob txoj kev sib sau ua ke, nrog ib lub vojvoog, ob lub vojvoog, ntxiv rau ob, peb, plaub lossis tsib yob kneading yob, ob lossis plaub yob sizing los xyuas kom meej qhov zoo. Cov txheej txheem yob txoj kev siv tshuab no feem ntau yog siv rau cov raj raj nrog lub cheeb tsawg dua φ114mm;

3. Nyob rau hauv kev tsim cov kav dej seamless, tswj thiab kho cov khoom tsis raug ntawm kev tsim thiab sizing tshuab hauv paus thiab tus nqi ntawm cov yob thaws, yog li ntawd txawm tias cov laus-fashioned units tuaj yeem tsim cov kav hlau zoo zoo;

4. Roll forming kev txawj ntse ntawm Teb Chaws Asmeskas, CTA tsim kev txawj ntse ntawm voestalpine, FF los yog FFX saj zawg zog forming txuj ci ntawm Nakata, Nyiv, thiab lwm yam, tuaj yeem ua kom cov duab ntawm cov welded sib koom ua ke tom qab tsim thiab zoo li zoo, thiab yog haum rau tus qauv Ib qhov dav ntawm cov kav dej seamless;

5. Thaum lub sijhawm hloov kho ntawm chav tsev, ua ntej ntawm tag nrho cov, nws yuav tsum tau ua kom ntseeg tau tias txhua qhov kev hla ntawm txoj kab ntsug ntawm qhov chaw yog zoo ib yam, thiab qhov chaw nruab nrab yog siv los ua lub hauv paus axis los nrhiav qhov chaw teev thiab lub tes tsho hauv nruab nrab. ) yog ib txoj kab ncaj nraim, thiab tsis tuaj yeem qhia nkhaus ntaus;

6. Txhawm rau txo qis deformation, 2 mus rau 3 kis tau ntxiv rau kev ua deformation ntawm cov kav dej seamless dua li cov kav dej dav dav;

7. Nyob rau hauv cov qauv deformation, qhov pib deformation taw tes ntawm view yuav tsum tau txo kom ib tug ruaj khov tom, lub hauv paus nkhaus taw tes ntawm view yuav tsum tau tsim kom tsim nyog, thiab lub rear deformation yuav tsum tau txo kom tsim nyog. Ntxiv deformation dhau tsis tsuas yog txo cov deformation quab yuam, tab sis kuj ua rau lub sawb Muaj lub sijhawm los tso cov kev ntxhov siab saum npoo, kom cov gradient ntawm qhov kev ntxhov siab nce qeeb, uas tuaj yeem tiv thaiv cov yeeb nkab seamless los ntawm kev tawg;
8. Ntau yam txuj ci tsim muaj qhov sib txawv thiab qhov tsis zoo, thiab haum rau cov xwm txheej sib txawv. Raws li kev siv seamless carbon steel kav, yuav tsum tau ua tib zoo saib xyuas thaum xaiv cov cuab yeej, thiab cov txheej txheem sib txawv yuav tsum tau xaiv.
