Hais txog Steel Rolling Mill

A steel dov zeb yog cov cuab yeej siv tshuab siv los ua kom tiav cov txheej txheem hlau dov. Nws yog hais txog cov khoom siv uas ua tiav tag nrho cov txheej txheem ntawm dov ntau lawm, suav nrog cov cuab yeej tseem ceeb, cov cuab yeej pabcuam, nqa thiab thauj khoom, thiab cov cuab yeej pabcuam. Tab sis feem ntau hais lus, lub tshuab dov tsuas yog hais txog cov khoom siv tseem ceeb.

Nws yog hais tias muaj dov mills nyob rau hauv cov teb chaws Europe nyob rau hauv lub xyoo pua 14th, tab sis nws tau sau tseg tias Leonardo da Vinci, ib tug Italian, tsim ib tug kos duab ntawm lub dov zeb nyob rau hauv 1480. Nyob rau hauv 1553, tus Frenchman Brulier dov kub thiab nyiaj daim hlau los ua. npib. Tom qab ntawd, dov mills tau tshwm sim nyob rau hauv Spain, Belgium, thiab United Kingdom. Lub rolling zeb tsim nyob rau hauv 1728 rau kev tsim round tuav yog ib tug tsim nyob rau hauv lub UK rau tsim round tuav nyob rau hauv 1728. Nyob rau hauv 1766, teb chaws Aas Kiv muaj ib tug series hom me me dov zeb. Nyob rau hauv nruab nrab xyoo pua -19th xyoo, thawj daim ntawv hlau dov zeb tau muab tso rau hauv kev ua haujlwm hauv tebchaws Askiv thiab lub nkoj hlau phaj tau dov. Xyoo 1848, Lub Tebchaws Yelemees tau tsim lub ntiaj teb dov zeb, thiab xyoo 1853, Tebchaws Meskas tau pib siv peb lub yob profile dov zeb (raws li pom los ntawm sab saib ntawm thawj peb yob dov zeb hauv daim duab 2), uas tau siv tshuab siv lub tshuab nqus tsev. engine tsav lifting platform. Tom qab ntawd, Tebchaws Meskas tau qhia txog Lauter mill. Thawj qhov nruam dov zeb yog tsim nyob rau hauv 1859. Lub universal profile dov zeb tshwm sim nyob rau hauv 1872; nyob rau hauv thaum ntxov xyoo pua 20th, nws tau ua rau ib tug semi nruam sawb dov zeb uas muaj ob peb yob roughing mills thiab tsib plaub yob xov mills.

Xyoo 1871, Tuam Tshoj tau pib siv cov dov mills ntawm cov nroj tsuag rub hlau (steel dov cog) nyob rau hauv Fuzhou Shipbuilding Bureau los yob hlau daim hlau nrog lub thickness tsawg dua 15 hli thiab square thiab round steel nrog thickness ntawm 6-120 hli. Xyoo 1890, Hanyang Iron Plant ntawm Hanyeping Tuam Txhab tau nruab nrog kab rov tav ob chav sawv ntsug 2450mm ob yob nruab nrab phaj dov zeb uas tau tsav los ntawm lub tshuab nqus tsev vacuum, peb sawv ntsug kab rov tav ob lub yob rail nqaj dov zeb uas tau tsav los ntawm lub tshuab nqus tsev, thiab 350 / 300mm me me dov zeb. Nrog rau txoj kev loj hlob ntawm metallurgical kev lag luam, tam sim no muaj ntau hom dov mills. Cov cuab yeej tseem ceeb ntawm cov dov zeb suav nrog lub hauv paus ua haujlwm thiab cov khoom sib kis.
