Rolling

Rolling yog txheej txheem compression tsis ncaj, thiab cov yob tuaj yeem tsim radial siab ntawm cov hlau ua haujlwm. Cov txheej txheem no deforms cov hlau thiab rub nws los ntawm qhov sib txawv ntawm qhov yob kom txo nws cov tuab thiab ua kom nws mus rau hauv qhov kev xav tau, thiab dov yog cais raws li qhov kub ntawm cov hlau dov. Yog hais tias qhov kub ntawm cov hlau yog siab tshaj nws cov recrystallization kub, feem ntau nyob ib ncig ntawm 1200 degree, ces cov txheej txheem no hu ua kub dov. Yog hais tias qhov kub ntawm cov hlau yog qis dua nws qhov kub thiab txias recrystallization, cov txheej txheem yog hu ua txias dov, thiab qhov no ua rau nws lub zog los ntawm kev ua kom tawv nqaij, txog li 20%.

 

Kev piav qhia

 

Muaj ntau hom dov mills xws li ob- siab dov mills, peb - siab dov mills, plaub- siab dov mills, tandem rolling mills thiab pawg dov mills, thiab yob stands yog tsim los tuav nr. ntawm cov khub ntawm cov yob uas tuaj yeem ua cov hlau sai sai rau hauv cov qauv steel profiles xws li I-beams, lub kaum sab xis bar, channel seem thiab ntsia. Kub dov txheej txheem ntau dua tonnage dua lwm cov txheej txheem hlau, thiab tom qab cov hlau dov kub txias, nws yuav ntsws, ua rau tsawg qhov tseeb thiab qhov ntxhib nto tiav.

 

Cov txheej txheem dov sib txawv

 

Cov txheej txheem hlau dov kuj tuaj yeem raug cais los ntawm geometry ntawm cov khoom siv hlau, thiab lawv raug cais raws li hauv qab no:

 

• √Xov dov, nws yog txheej txheem txheej txheem txias uas siv cov tuag ntawm cov chais los ua cov xov ntawm cov ntsia hlau thiab bolts los yog tsim cov iav, thiab nws yog cov txheej txheem hlau uas tsim cov xov rau hauv daim iav duab ntawm cov menyuam tuag. Cov txheej txheem no tuaj yeem tsim siab - lub zog quab yuam lub cev hloov cov khoom ntawm cov khoom siv hlau ua kom lub hauv paus thiab cov xov sib zog thiab muaj zog dua.
•  
• √Phaj rolling, tseem hu ua yob dabtsi yog khoov, yog ib tug nruam dabtsi yog khoov ua hauj lwm uas ib tug ntev sawb ntawm hlau, feem ntau coiled steel, yog dhau los ntawm sib law liag ntawm yob los tsim ib tug nkhaus, xws li lub tog raj kheej los yog lwm yam nkhaus seem.
•  
• √Tube tho, nws yog cov txheej txheem kub dov siv los tsim seamless hollow raj xws lidej boiler tube. Ib lub cylindrical billet uas muaj cua sov yog noj ntawm ob lub convex-tapered yob thiab ib lub mandrel nyob ruaj ruaj, thiab cov rolls compress thiab tig lub billet, tsim kom muaj lub hollow tubing.

 

Rolling Mills Hom

 

Cov tshuab siv rau dov, hu ua dov zeb, los ntawm ntau yam kev teeb tsa nyob ntawm daim ntawv thov:

 

• √Ob- lub siab dov zeb, muaj ob lub yob rotating nyob rau hauv opposite lus qhia
• √Peb- lub siab dov zeb, muaj peb yob, nrog rau sab saum toj thiab hauv qab tig nyob rau hauv tib txoj kev thiab lub nruab nrab yob nyob rau hauv lub opposite kev taw qhia, tso cai rau dov nyob rau hauv ob qho tib si kev taw qhia yam tsis muaj reversing lub zeb.
• √Plaub -Rolling zeb siab, siv ob lub yob ua haujlwm me me hauv kev sib cuag nrog cov hlau thiab ob lub yob loj dua los tiv thaiv cov yob ua haujlwm los ntawm deflecting.
• √Multi- zeb zeb siab, tseem hu ua pawg zeb, nws cov qauv muaj ntau cov ntaub ntawv thaub qab uas txhawb nqa kev ua haujlwm yob, tso cai rau kev siv cov kev kub siab los yob cov ntaub ntawv nyuaj los yog nyias, xws li stainless hlau thiab tooj liab ntawv ci.
• √Universal dov zeb, nws yog siv rau kev tsim cov duab zoo li H-beams thiab kuv beams.

 

 

Nta ntawm Kub Rolling & Cold Rolling

 

Kub dov muaj ob qhov zoo thiab qhov tsis zoo, thiab lawv tau sau tseg raws li hauv qab no:

 

Qhov zoo:

• √Ntau dua deformation, nws tuaj yeem tso cai rau txo qhov loj ntawm cov khoom tuab hauv ib qho dhau los.
• √Tsawg tus nqi tsim khoom
• √Txo cov cuab yeej hnav

 

Qhov tsis zoo:

• √Tsawg qhov tseeb qhov tseeb, thaum cov hlau ua haujlwm txias, nws yuav ntsws. Yog li ntawd, rau qee qhov profile tshwj xeeb, kev ua haujlwm txias xws li kev kos duab txias yog xav tau los txhim kho qhov tseeb qhov tseeb.
• √Qhov chaw tsis zoo vim yog txheej txheej oxide lossis nplai uas yuav tsum tau muab cov txheej txheem tshem tawm cov nplai.
