Cov keeb kwm kev hloov kho thiab yav tom ntej saib xyuas ntawm cov zeb dov

Keeb kwm ntawm tib neeg hlau ua tuaj yeem tsim rov qab mus rau 4000 BC, tab sis cov xaim tshuab siv cov txheej txheem kev lag luam tau yug hauv lub xyoo pua 18th. Raws li cov khoom tseem ceeb ntawm cov txheej txheem hlau niaj hnub ntawm cov txheej txheem dov ntawm cov tshuab dov yog qhov xwm txheej me ntawm kev lag luam kev tswj. Kab lus no yuav rov xyuas cov thev naus laus zis ntau dhau ntawm cov tshuab hluav taws xob rau digital ntxaib thiab kev soj ntsuam qhov kev xav tsis thoob.
I. LUB TSWV YIM NTAWM COV KHIB KHIB (18th - 19 th tiam)
Nyob rau hauv 1766, British Engineer Henry Cort ua cov reciprocating dov lub tshuab, uas rau thawj zaug ua tiav rolling ntawm cov hlau daim hlau, nce ntau dua los ntawm 20 zaug. Xyoo 1783, thawj chav - powered Rolling tshuab tau yug los hauv lub zog kiv kev thiab dov thev naus laus zis. Cov thev naus laus zis thev naus laus zis lub sijhawm no tsom rau:
Cov khoom siv ntawm cov yob hloov zuj zus los ntawm cam khwb cia hlau kom siab - rabbon cam khwb cia hlau
Lub yob ceev nce ntxiv los ntawm 0.5m / min mus rau 5m / min
Lub thickness kam kam rau cov khoom tau tswj tsis pub dhau ± 0.5mm
Ii. Cov kiv puag ncig ntawm kev siv hluav taws xob thiab kev siv tshuab (thaum xyoo pua ntxov)
Xyoo 1926, Universal Rolling tshuab tsim los ntawm Krupp ntawm lub teb chaws Yelemees tau ua haujlwm txuas ntxiv ntawm Seem Steel. Thaum xyoo 1950, kev qhia ntawm lub koos pij tawj tswj cov hlua dov kom mus txog qib micrometer. Qhov tseem ceeb nce nce qib:
Qhov hloov ntawm cov pa hluav taws los ntawm DC Motors (1920)
Daim ntawv thov ntawm automatic Thickness tswj system (AGB) (1952)
Qhov tseeb ntawm qhov thib ob -}} plein hloov nyob rau hauv kub nrum rolling tshuab (1963)
III. Digital txawj ntse hloov pauv (txij li xyoo pua 21st)
Niaj hnub so machine tau sib xyaw ua ke ntawm cov khoom, cov ntaub ntawv loj, thiab cov thev naus laus zis txawj ntse. Xyoo 2023, baowu pawg "lub teeb lub teeb dub" tsim lub tshuab dov ua tiav:
Ib tuab tswj qhov raug ntawm 0.01mm
Ntse teem sijhawm txo cov hluav taws xob noj los ntawm 30%
Kev saib xyuas kev ua kwv yees txo qis qis los ntawm 70%
Tam sim no, ntse Rolling Machine siv 5G + Industrial Internet tau rov ua cov ciaj ciam ntawm kev ua hlau. Nrog kev nce qib ntawm cov ntaub ntawv science, cuam tshuam thev naus laus zis xws li chav tsev sov superconducting yob tau yav tom ntej, txuas ntxiv tsav cov kev txhim kho ntawm kev tsim khoom lag luam.
