Nyias Phaj Rolling Mill Rau Industrial Production
| Khoom npe | Nyias phaj dov zeb | Yam uas muaj feem | Machinery, kev lag luam ntau lawm |
| Qeb | Tshuab | Kawm paub | Metallurgical engineering |
| Hom | Runxiang | Qhov chaw ntawm keeb kwm | Guangxi, Suav teb |
| Cov teb uas muaj feem | Rolling zeb txheej txheem | Seb kev cai | Yog lawm |
Nyias phaj zebyog lub dov (0.3 ~ 4.0) hli × (600 ~ 1000) hli nyias phaj dov zeb.Tus txheej txheem xa khoom loj ntawm daim ntawv kub dov tiav yog (0.5 ~ 2.0) × 1000 × 2000mm (thickness × dav × ntev), uas yog dov los ntawm cov lus qhia tshwj xeeb slab siv 1200 daim ntawv zeb.Raws li qhov tshwm sim ntawm high-kub cua sov ntawm slab nyob rau hauv multi-pass dov.Tom qab qhov loj deformation, cov npoo tsis ncaj, yog li plaub sab raug txiav.Yuav kom ua tiav tus txheej txheem xa khoom loj, qhov tseeb dov tawm ntawm qhov tsim nyog.
Feem ntau qhov loj ntawm lub rooj tsavxwm ntxhib tom qab dov yog hais txog 1040 × 2320mm (dav × ntev), thiab qhov zoo ntawm 1000 × 2000mm yog txiav los ntawm chav tsev disc, tus nqi shear (shear rate) ntawm lub rooj tsavxwm ntxhib tom qab shearing yog: 1000 × 2000 / 1040 × 2320 = 82.89% Qhov poob los ntawm kev txiav ntug thiab lub taub hau nce mus txog 17.11%, uas dhau los ua lub hauv paus tseem ceeb hauv kev txhim kho tus nqi.Kev siv cov txheej txheem ob-loj ntau lawm tuaj yeem txo qhov txiav lub taub hau poob.
Rolling txoj cai
Lub hauv paus ntsiab lus ntawm ob-ntug dov yog tias ob pawg ntawm cov khoom tiav tau txais tom qab shearing ob-ntug ntev ntawm cov laug cam ib zaug.Qhov kom zoo dua yog tias ob pawg ntawm daim hlau yuav tsum tau txiav ob lub taub hau thiab cov tails, tag nrho ntawm plaub daim, thaum ob-fold rolling system tsuas yog yuav tsum tau txiav ib txheej ntawm lub taub hau thiab tails, piv nrog qhov txo qis ntawm ib txheej. taub hau thiab tails, yog li txhim kho cov tawm los.
Lub shear tus nqi tuaj yeem suav tau raws li hauv qab no: (1000 × 2000) × 2 / 1040 × 4500 = 85.47%, yog li nws tuaj yeem pom tias qhov sib tsoo tuaj yeem nce los ntawm 2.58 feem pua ntawm cov ntsiab lus piv nrog ib zaug dov los ntawm kev siv ob npaug. quav dov.
Cua sov system
Qhov siab tshaj plaws kev nyuaj siab yuav tsum tsis txhob ntau tshaj 35%, vim hais tias ob-fold dov tshaj ib-fold dov feem ntau nce 2 mus rau 3 lub sij hawm, ua rau lub tshav kub dissipation cheeb tsam thiab tshav kub dissipation lub sij hawm nce, thiaj li yuav xyuas kom meej qhov kawg dov kub, lub dav qhib. Qhov kub ntawm tib qhov tshwj xeeb tshaj li ib zaug dov nce los ntawm 30 txog 50 ℃.
