Rolling zeb: keeb kwm thiab niaj hnub faib

Ib tug dov zeb raws li ib tug ntaus ntawv rau cov zauv co thiab lwm yam ntaub ntawv ob peb yam siab yob yog thawj hais nyob rau hauv tej hauj lwm ntawm Leonardo da Vinci. Lub hiob mechanism piav los ntawm tus poj tswv nyob rau hauv 1495, npaj rau cov kev kho mob ntawm tin. Rolling pab kiag li lawm twb tau lug siv nyob rau hauv lub xyoo pua 17th, nyob qhov twg lawv ua hauj lwm nyob rau hauv lub hauv paus ntawm phau ntawv actuators, uas tom qab hloov los ntawm dej (dej log), thiab ces mus rau zog. Niaj hnub no, koj qev los cov khoom nrog ib tug phau ntawv tsav yog feem ntau siv rau handicraft ua hauj lwm.

Ib tug dov zeb raws li ib feem ntawm cov khoom muaj ib tug cev lub ntsiab (ua hauj lwm muag zaub, uas yuav yog los ntawm ob tug mus rau ob peb yob, fais fab thiab pab kiag li lawm, lub hwj chim kis tau tus mob mus rau lub chais ntawm lub engine) thiab koom haum pab (khoom kev tsiv workpieces, lawv txiav, wires, tilting, etc. ) .. Tus tsim ntawm tej khoom txuas rau cov khoom yam, uas nws tso tawm.

Kuav los tiag khoom, nyob ntawm seb lub hom ntoo khaub lig-section yog muab faib ua ob peb pab pawg, xws li:

- ib cov yeeb nkab (seamless los yog ua los ntawm vuam);

- dov daim ntawv (nyias daim ntawv los yog dov phaj (4 mm));

- kuav los tiag (dawb los yog zoo li tus);

- tshwj xeeb dov (angular C-zoo li tus, nrog ib tug kuj tsis paub meej profile, etc.).

Lub dov zeb raws li hom khoom yuav raug muab tso rau ib qho ntawm cov nram qab no pawg: pipelines, lento-, zhesteprokatnye, tshwj xeeb, daim ntawv, hlau, shtripsovye, broadband, high-zoo, crimping (mas blooming), billet, dov zeb. Khoom ntawm no hom yog tua. Piv txwv li, tsuas yog rau ib tug me me zeb yuav muaj ib tug kaum tsib meters ntev, thiab qhov loj tshaj plaws rau hnub tim daim qauv ntawm qhov ntev occupies 5,500 meters (muaj los ntawm "Anshen Andes Hlau Steel Group").

Ib suam ntawm mills rau tsim nta raws li nram no:

- ib tug single- (lawv muaj pes tsawg leeg yog crate, augmented, piv txwv li, rau hluav taws xob motors, lub tsib clutches, plaub Gearboxes peb sawv loj iav thiab ob tug koob);

- Tawm dov zeb (stand cov txheej txheem ntawm ib tug tom qab lwm, tej zaum nyob rau hauv ntau yam kab, cov khoom ua nyob rau hauv ib tug kev taw qhia);

- serial (ob peb leeg-stand mills txheej txheem sequentially los yog nyob rau hauv ib tug txawv kev txiav txim);

- tas mus li (billet ua ib txhij nyob rau hauv ib tug xov tooj ntawm lub tawb);

- semi-nruam (muaj tas mus li seem thiab linear kho vajtse Cheebtsam).

Yuav ua li cas puas muaj tus zeb? Ua ntej, cov hlau ingot yog rhuab nyob rau hauv tshwj xeeb qhov dej (kub txog 1800 C), whereupon nws muab lub fais tsheb mus rau lub thawj ua (nyob rau hauv blooming los yog slabbing) nyob rau lub ingot yog tau los ntawm cov tuav. Tom ntej no, ib tug nyob rau lwm cov khoom hom dov hlau los xij npaj los yog tiav lawm khoom ib tug predetermined zoo, xws li ib tug kev tsheb nqaj hlau, thiab lwm tus neeg. Niaj hnub nimno khoom feem ntau yog ib tug casting-dov mills uas yuav ua lub workpiece nyob rau hauv sawv ntawm ib tug ceev ntawm txog 300 km ib teev.

Qhuav ntawm dov mills yog ib tug complex thiab kim txheej txheem, tsis tau niaj hnub no muaj tuam txhab uas muag nyob rau hauv Russia uas tsim tej khoom. Nyob rau hauv tas li ntawd mus rau lub ntsiab thiab koom haum pab khoom rau cov muaj kev vam meej cov lag luam ntawm lub complex yuav tsum tau high-precision khoom, lubrication cov khoom, raws li zoo raws li muab hluav taws xob rau mills nrog ib tug tag nrho lub peev xwm ntawm 200-300 MW.
