Cov txheej txheem ntau lawm ntawm seamless steel kav yog cumbersome thiab nruj. Tom qab cov yeeb nkab seamless steel tsim, qee qhov kev sim yuav tsum tau ua. Koj puas paub txoj kev ntsuas flattening thiab cov kauj ruam ntawm seamless steel yeeb nkab?

1) Flatten tus qauv:

1. Cov qauv yog txiav los ntawm ib feem ntawm cov seamless steel yeeb nkab uas tau dhau qhov kev kuaj pom, thiab cov qauv yuav tsum yog tag nrho lub ntsej muag cov yeeb nkab seem ntawm cov khoom siv yeeb nkab.
2. Qhov ntev ntawm cov qauv yuav tsum tsis pub tsawg tshaj 10mm, tab sis tsis ntau tshaj 100mm. Cov npoo ntawm cov qauv tuaj yeem sib npaug los yog chamfered los ntawm kev ua ntaub ntawv lossis lwm txoj hauv kev. Nco tseg: Yog tias qhov ntsuas tau ua tau raws li qhov yuav tsum tau ua, cov npoo ntawm cov qauv yuav tsis raug muab sib dhos lossis chamfered.
3. Yog hais tias nws yuav tsum tau nqa tawm nyob rau hauv lub kawg ntawm ib tug puv-ntev raj. Thaum lub sij hawm xeem, qhov kev txiav yuav tsum tau ua perpendicular mus rau lub longitudinal axis ntawm cov yeeb nkab ntawm qhov ntev ntawm tus qauv los ntawm lub kawg ntawm lub ntsej muag ntawm cov yeeb nkab, thiab txiav qhov tob yuav tsum yog tsawg kawg yog 80% ntawm lub sab nraud txoj kab uas hla.

2) Cov khoom siv kuaj:

Qhov kev ntsuam xyuas tuaj yeem ua tiav ntawm lub tshuab ntsuas universal lossis lub tshuab ntsuas siab. Lub tshuab kuaj xyuas yuav tsum tau nruab nrog ob sab saum toj thiab qis qis sib npaug platens, thiab qhov dav ntawm qhov sib npaug platens yuav tsum tshaj qhov dav ntawm cov qauv flattened, uas yog, tsawg kawg yog 1.6D. Qhov ntev ntawm lub phaj nias yog tsis tsawg tshaj qhov ntev ntawm tus qauv. Lub tshuab kuaj muaj peev xwm ua kom cov qauv ua kom haum rau tus nqi siab. Lub platen yuav tsum muaj qhov nruj txaus thiab muaj peev xwm tswj tau qhov ceev ntau yam uas yuav tsum tau ua rau kev sim.

3) Cov xwm txheej xeem thiab cov txheej txheem ua haujlwm:

1. Feem ntau qhov kev xeem yuav tsum tau ua nyob rau hauv chav tsev kub ntawm 10 ° C ~ 35 ° C. Rau kev ntsuam xyuas uas yuav tsum tau tswj xyuas, qhov ntsuas kub yuav tsum yog 23 ° C ± 5 ° C. Lub flattening ceev ntawm tus qauv tuaj yeem ua tau
20-50mm / min. Thaum muaj kev tsis sib haum xeeb, qhov txav ceev ntawm lub platen yuav tsum tsis pub tshaj 25mm / min.

2. Raws li cov qauv tsim, lossis kev pom zoo ntawm ob tog, qhov kev ncua deb H ntawm lub platen yuav tsum tau txiav txim siab.

3. Muab cov qauv ntawm ob lub phaj sib luag. Cov welds ntawm welded kav yuav tsum tau muab tso rau hauv txoj hauj lwm teev nyob rau hauv cov khoom thiab cov qauv. Siv lub tshuab xovxwm lossis lub tshuab ntsuas kom siv lub zog hauv qhov kev taw qhia radial, thiab ntawm qhov ceev tsis tshaj 50mm / min, tusyees nias rau lub tiaj tiaj H, tshem tawm cov load, tshem tawm cov qauv, thiab pom qhov muag ntawm qhov khoov. ntawm tus qauv.

Cov kev ceev faj:

Thaum lub sij hawm flattening xeem, lub flattening nrug H yuav tsum tau ntsuas nyob rau hauv load. Nyob rau hauv cov ntaub ntawv ntawm kaw flattening, qhov dav ntawm kev sib cuag ntawm lub puab nto ntawm tus qauv yuav tsum yog tsawg kawg yog 1/2 ntawm lub puab dav b ntawm tus qauv qauv tom qab flattening.

Kev ntsuas kev ua tau zoo ntawm seamless steel yeeb nkab plays lub luag haujlwm tseem ceeb hauv hardness, melting point, corrosion resistance thiab siab ntawm seamless steel yeeb nkab, thiab qhov kev sim no yuav tsum ua kom zoo.
