Muaj cov teb chaws tsim, xws li Tebchaws Meskas, Nyiv, Lub Tebchaws Yelemees thiab lwm yam, muaj ntau cov khoom siv niaj hnub kub dov cov yeeb nkab, feem ntau tsis siv neeg cov yeeb nkab dov tshuab thiab cov yeeb nkab dov tshuab, kev tsim cov yeeb nkab steel suav txog 92 feem pua. ntiaj teb kub dov yeeb nkab tso zis, qhov loj hlob ntawm steel yeeb nkab 7.5 feem pua. Lawv tsim txog 15 feem pua ntawm lub ntiaj teb cov hlau hauv cov raj kub dov.
Nyob rau hauv xyoo tas los no, billet nruam casting tau ua tiav zoo thiab maj mam hloov cov dov billet. Yog li ntawd cov hlau yield tus nqi nce 10 feem pua -15 feem pua, cov nqi hluav taws xob txuag tau ntau dua 40 feem pua, tus nqi txo qis heev. Txij li thaum xyoo 1980s, lub conical yob nkag mus rau qhov system, txwv kev txav mandrel nruam dov cov yeeb nkab teeb thiab lwm yam khoom siv tau zoo heev tau siv dav. Kev txwv txav mandrel nruam dov tshuab tuaj yeem tsim cov raj steel nrog txoj kab uas hla mus txog 426mm thiab ntev txog 50m. Kev ua haujlwm siab ntau lawm, qhov siab tshaj plaws ntawm ib lub tshuab tuaj yeem ncav cuag 800, 000 rau 1, 000, 000 T /a; Cov khoom lag luam zoo yog qhov zoo, sab nraud txoj kab uas hla tuaj yeem ncav cuag ± 0.2 feem pua -0.4 feem pua, phab ntsa thickness sib txawv nyob rau hauv thaj tsam ntawm ± 03 feem pua -6.5 feem pua. Nyob rau hauv lub hauv paus ntawm ob - siab txwv txav mandrel nruam dov tshuab, peb - siab adjustable txwv txav mandrel nruam dov tshuab tau tsim tawm txawv teb chaws.
Nyob rau hauv xyoo tas los no, welded yeeb nkab tso zis ntawm txhua lub teb chaws tsim steel ntau tshaj seamless yeeb nkab tso zis, xws li Nyiv welded yeeb nkab hauv xyoo 1973 tau suav txog 80 feem pua ntawm cov yeeb nkab steel tso tawm. Nrog rau txoj kev loj hlob ntawm txoj kev tsheb thauj mus los ntev, qhov kev faib ua feem ntawm txoj kab uas hla loj welded yeeb nkab yog nce. Nyob rau xyoo 1970, qhov siab tshaj plaws sab nrauv ntawm txawv teb chaws UO txoj kev welded yeeb nkab tau nce mus rau 1626mm, o-hom xovxwm yog mus txog 6000MN, thiab lub siab tshaj plaws phab ntsa thickness tau nce mus rau 40mm. Lub peev xwm tsim tau txhua xyoo ntawm UO tsim cov yeeb nkab vuam tshuab yog 1.1 lab tons.
Cov kauv vuam yeeb nkab siv lub tshuab tsim kom pom cov hlua khi tam sim tom qab tsim, thiab tom qab ntawd nws raug xa mus rau ntau lub tshuab vuam rau ob sab vuam tom qab nws raug txiav rau qee qhov loj, kom lub tshuab tsim siv rau. ob peb.
Vim tias qhov kev thov nce ntxiv rau qhov tseeb, cov phab ntsa nyias thiab lub zog siab tshwj xeeb steel yeeb nkab, kev tsim cov yeeb nkab txias thiab cov yeeb nkab txias rub tawm sai heev.
Muaj ntau lub sijhawm, ntau-yob, ntsug, planetary thiab txuas txuas cov yeeb nkab dov tshuab. Lub caij txias tube dov tshuab yog siv dav tshaj plaws. Kev kos duab txias yog txoj hauv kev tseem ceeb ntawm kev tsim cov yeeb nkab steel yeeb nkab. Muaj peb hom tshuab kos duab txias: hom pendulum, hom teb thiab nruas hom. Nruas hom raj tshuab kos duab nyob hauv thaj chaw me me, kev nqus nrawm yog siab, tau nrov thiab siv.
