1.Dab tsi yog qhov kev siv ntawm txias-rolled coils? Qhov dav cuam tshuam li cas?
Kev siv tus nqi ntawm qhov txias- dov coils feem ntau yog hais txog qhov feem pua ntawm tag nrho cheeb tsam ntawm qhov kawg ua tiav rau tag nrho cheeb tsam ntawm qhov txias - dov coil noj. Dav yog ib qho tseem ceeb tshaj plaws geometric tsis cuam tshuam rau kev siv tus nqi, feem ntau los ntawm cov txheej txheem hauv qab no:
Ntug Tshem Tawm Poob: Txias- dov coils muaj ob ntug (feem ntau 5-20mm txhua). Cov npoo no, vim ntug tawg los yog tsis sib xws, yuav tsum tau muab tshem tawm thaum slitting los yog shearing, ua seem. Yog hais tias qhov yuav tsum tau ua tiav cov khoom dav tuaj yeem siv tag nrho qhov nruab nrab tshem tawm, pov tseg yog txo qis.
Layout Economy: Thaum lub sij hawm blanking (stamping lossis slitting), ntau qhov chaw yuav tsum tau teem caij hla qhov dav ntawm lub kauj. Yog tias qhov dav tso cai rau kev teeb tsa ntawm cov khoom hauv ntau qhov sib txawv ntawm qhov sib txawv me me, qhov kev siv tus nqi yog siab; conversely, yog hais tias qhov dav tshwm sim nyob rau hauv ib tug dav, unusable strip ntawm cov khoom tom qab kev npaj, qhov kev siv tus nqi txo.
2.Vim li cas "dav cov khoom siv ntau dhau" suav tias yog tus pab cuam loj tshaj plaws rau kev siv poob?
Tsau Loss: Piv txwv tias ib feem yuav tsum yog 100mm dav, tso ob ntawm lawv yuav xav tau 200mm. Ntxiv shearing clearance thiab ntug trimming, ib tug 215mm wide steel kauj yuav xav tau. Qhov ntxiv 15mm yog qhov dav dav (nrog rau cov ntug trimmings).
Marginal Poob: Rau qhov nqaim strips, txhua 1 hli nce hauv qhov dav tuaj yeem txhais tau tias yog ib qho khoom seem ntxiv. Hauv kev tsim khoom loj, txawm tias ob peb millimeters pov tseg hauv qhov dav tuaj yeem sib sau mus rau ob peb tons lossis txawm tias kaum tawm tons ntawm cov khoom poob txhua xyoo. Yog li ntawd, thaum xaiv qhov dav, nws yuav tsum tau xaiv kom haum raws nraim qhov ntau ntawm qhov dav, zam ib nrab -ntev qhov sib txawv.
3.Los ntawm qhov kev xav ntawm txias- dov coil ntau lawm, puas muaj kev sib raug zoo ntawm qhov dav thiab tawm los (siv)?
Ntug Crack Tshem Tawm: Thaum lub sij hawm kub thiab txias dov, microcracks tuaj yeem txhim kho ntawm cov npoo ntawm cov sawb vim muaj kev ntxhov siab. Steel mills yuav tsum tshem tawm cov npoo tawg no thaum lub sij hawm tiav cov khoom shearing (ntug trimming). Rau qhov nqaim specifications, tus nqi trimming tso nyiaj rau qhov feem ntau ntawm tag nrho qhov dav; yog li ntawd, nqaim txias- dov coils feem ntau muaj qhov tawm los me ntsis qis dua qhov dav dua.
Daim ntawv cog lus Batching: Txhawm rau txhim kho kev ua tau zoo, steel mills nyiam ua pab pawg xaj nrog qhov dav zoo sib xws ua ke rau kev tsim khoom. Yog tias tus neeg siv khoom xaj qhov dav uas yog qhov tshwj xeeb dhau los yog nqaim dhau, nws tuaj yeem ua rau muaj teeb meem ntawm kev teem caij thiab tej zaum yuav xav tau kev sib cais, yog li cuam tshuam rau tag nrho cov kub kub -them nqi thiab tawm los ntawm batch.
4.Rau cov neeg siv qis qis (xws li cov nroj tsuag stamping), yuav ua li cas xaiv qhov dav kom siv tau ntau tshaj plaws?
** Layout Optimization:** Thaum tsim pwm los yog shearing schemes, siv computer -pab layout kom pom qhov zoo coil dav uas faib ib feem ntawm qhov dav, txo qhov dav seem.
**Multi-Part Mixed Layout:** Yog tias ib feem tsis tuaj yeem ua tiav nrog qhov chaw, sim tso lwm qhov ntawm qhov dav zoo sib xws rau tib lub strip rau cov txheej txheem sib xyaw (ntau ntawm cov kab blanking). Qhov no siv cov khoom siv ntau dhau thiab txhim kho qhov kev siv cov coil tag nrho.
**Kev zam qhov "Dab ntxiab dav:** Qee zaum, qhov muag tsis pom qhov dav dua (xav tias cov khoom siv ntau dua zoo dua) tuaj yeem cuam tshuam. Piv txwv li, yog tias 1000mm dav coil tuaj yeem txiav ob qhov zoo kawg nkaus, siv 1500mm dav coil tuaj yeem tso cai rau peb. Txawm li cas los xij, yog txiav peb qhov yuav tsum tau 1500mm, tab sis tsuas yog tom qab peb 140mm trimming, qhov tseeb tsuas yog 140mm. qhov chaw rau peb qhov chaw lossis cov khoom loj ntawm cov khoom siv ntau ntxiv tom qab txiav peb, thaum kawg txo kev siv.
5.Thaum kev txiav txim tiag tiag, koj yuav tsum xaiv tus qauv dav lossis qhov dav? Qhov no yuav cuam tshuam li cas rau kev siv?
Standard Width (feem ntau siv dav):
Qhov zoo: Steel mills tswj cov khoom lag luam tsis tu ncua, ua kom ruaj khov; tus nqi feem ntau qis dua, thiab lub sijhawm xa khoom luv dua.
Qhov tsis zoo: Cov neeg siv yuav tsum tau kho lawv cov txheej txheem kom haum raws li tus qauv dav, uas ua rau muaj kev siv qis me ntsis.
Txhua qhov dav (Daim ntawv cog lus dav):
Qhov zoo: Qhov dav tuaj yeem hloov kho rau tus neeg siv qhov kev pom zoo tsim, theoretically maximizing siv thiab txo qis ntug pov tseg.
Disadvantages: Qhov no yog ib yam khoom uas tsis yog -tus qauv; steel mills tej zaum yuav xav tau tshwj xeeb yob nws, ua rau cov nqi siab dua (cov cim ntxiv), qhov loj dua qhov kev txiav txim kom tsawg, thiab lub sijhawm xa khoom ntev dua.
