Lub tshuab dov ua cov khoom siv rau kev ua cov hlau thiab lwm yam khoom siv los ntawm lub siab ntawm ob peb rotating rolls yog thawj zaug hais txog kev ua haujlwm ntawm Leonardo da Vinci. Cov txheej txheem qub tshaj plaws, piav qhia los ntawm tus tswv zoo hauv xyoo 1495, tau npaj rau kev ua cov tin. Rolling li twb tau siv dav heev nyob rau hauv lub xyoo pua 17th, qhov chaw uas lawv ua hauj lwm raws li phau ntawv tsav tsheb, uas tom qab hloov los ntawm dej (dej log), thiab ces los ntawm chav. Niaj hnub no, cov cuab yeej siv tes ua lag luam feem ntau yog siv los ua cov khoom siv tes ua haujlwm.

Lub tshuab dov ua ib feem ntawm nws cov cuab yeej muaj qhov tseem ceeb (kev ua haujlwm sawv ntsug, uas tuaj yeem ua tau los ntawm ob mus rau ob peb yob, hluav taws xob lub cev muaj zog thiab cov khoom siv uas xa lub zog rau cov yob los ntawm lub cav) thiab pab (cov khoom siv rau kev txav mus los. daim ntawv, txiav lawv, kho, edging, thiab lwm yam). Kev tsim cov khoom siv tshwj xeeb yog khi rau hom khoom nws tsim.

Rental khoomraws li hom ntoo khaub lig tau muab faib ua ob peb pawg, suav nrog:

- cov kav dej (seamless lossis welded);

- cov khoom siv (cov ntawv nyias lossis cov ntawv tuab (ntau dua 4 hli));

- cov khoom ntev (puab lossis tiaj);

- cov khoom tshwj xeeb dov (kaum, C-puab, sib txawv profile, thiab lwm yam).

Rolling zeb los ntawm cov khoom lag luam tuaj yeem muab rau ib pawg hauv qab no: yeeb nkab, daim kab xev, tin dov, tshwj xeeb, ntawv, hlau, sawb, broadband, ntu, swaging (tsuas yog tawg), billet, rail thiab beam mills. Hom khoom siv no loj. Piv txwv li, ib lub zeb suav tias me me yuav ntev li kaum tsib meters, thaum lub zeb loj tshaj plaws rau hnub tim yog 5,500 meters ntev (muaj los ntawm Anshen Iron Thiab Steel Group).

Kev faib tawm ntawm dov mills los ntawm cov qauv tsim yog raws li hauv qab no:

- ib lub tawb (lawv suav nrog lub tawb, ntxiv rau, piv txwv li, nrog rau lub tshuab hluav taws xob, tsib clutches, plaub lub thawv, peb lub tawb iav thiab ob lub ntxaiv);

- linear mills (stands nyob ib leeg, qee zaum hauv ob peb kab, cov khoom raug ua tiav hauv ib qho kev taw qhia);

- sequential (ntau lub mills ib leeg nyob ib ntus lossis sib txawv);

- nruam (lub workpiece yog ua tiav ib txhij nyob rau hauv ib tug xov tooj ntawm stands);

- ib nrab txuas ntxiv(muaj cov ntu tas mus li thiab cov khoom siv linear).

Lub tshuab dov ua haujlwm li cas? Ua ntej, cov hlau ingot yog rhuab nyob rau hauv tshwj xeeb qhov dej (kub yog hais txog 1800 C), tom qab uas lub fais tsheb muab nws rau thawj ua (rau slabbing los yog tawg), qhov twg tuav tau los ntawm lub ingot. Tsis tas li ntawd, cov ntawv hlau lossis cov khoom tiav ntawm cov duab muab, xws li cov ntsia hlau, thiab lwm yam, tau txais los ntawm lawv ntawm lwm cov khoom siv dov. Cov cuab yeej siv niaj hnub no, raws li txoj cai, yog foundry thiab dov mills uas tuaj yeem ua cov khoom siv hluav taws xob nyob rau ntawm qhov ceev ntawm txog 300 km ib teev.

Kev tsim cov dov mills yog txheej txheem nyuaj thiab kim, txawm li cas los xij, niaj hnub no hauv Russia muaj cov tuam txhab tsim cov khoom zoo li no. Ntxiv nrog rau cov khoom siv tseem ceeb thiab pabcuam, kev ua haujlwm tiav ntawm txoj haujlwm yuav tsum muaj kev ua haujlwm siab, cov khoom siv lubrication, nrog rau kev muab cov mills nrog hluav taws xob nrog tag nrho cov peev txheej txog li 200-300 megawatts..
