Txias-dov yeeb cov yeeb nkab tsis xws luag thiab kev tiv thaiv

Lub ntsiab ua tau zoo tsis xws luag ntawm cov kav dej txias-rolled steel suav nrog: Thaj av tsis sib xws, sab nraud ntawm cov kab nrib pleb, qhov chaw saum npoo av, wrinkles, thiab lwm yam.

Txhim kho cov phab ntsa tuab yog ntawm lub raj dawb yog ib qho tseem ceeb ntawm cov phab ntsa tuab ntawm cov kav hlau txias-dov steel kav.

② Ua kom ntseeg lub phab ntsa tuab thiab khaws cov raj uas tsis muaj peev xwm tseem ceeb rau kev txhim kho phab ntsa tuab ntawm cov raj txias. Dhau-apling los yog hauv qab-pickling ntawm lub raj raj dawb yuav tsum tiv thaiv, thiab cov npoo ntawm lub raj dawb yuav tsum tau tiv thaiv los ntawm kev sib tw dhau los lossis tsis muaj menyuam. Yog tias pitting lossis residual hlau oxide cov nplai yog tsim, ntxiv dag zog rau cov cable cov cuab yeej xim av thiab tshuaj xyuas kom sai ntawm cov pas nrig mandrel thiab dov zawj cov blocks.

③ Txhua qhov kev ntsuas kom txo tau lub zog dov yog pab kom cov raj tawg, txo cov tshuab raj uas muaj zog thiab tshuaj txhuam cov khaub noom thiab tshuaj tiv thaiv cov yeeb nkab dov cov cuab yeej. Thaum cov yeeb nkab dov cov cuab yeej tau pom tias yog hnav kom hnyav, lawv yuav tsum tau hloov nyob rau lub sijhawm kom tiv thaiv cov hlab hlau sab nraud ntawm cov hlau sib txuas los ntawm kev ua siab ntev.

Cov kab nrib pleb ntawm saum npoo ntawm cov kav hlau steel tsim tawm thaum lub sij hawm txias dauv txias yog tshwm sim los ntawm cov hlau tsis sib xws ntawm cov hlau. Txhawm rau tiv thaiv qhov chaw tawg nyob hauv cov yeeb nkab steel nyob rau lub sijhawm txias, lub raj dawb paug yuav tsum tau tshem tawm cov hlau ua haujlwm ntawm cov hlau thiab txhim kho cov hlau.

⑤ Tus nqi ntawm cov rolling deformation muaj qhov tseem ceeb uas muaj kev cuam tshuam rau cov nrib pleb ntawm cov kav hlau txias-rolled steel kav. Kev txo cov kev tiv thaiv uas tsim nyog yog ib txoj kev ua tau zoo heev los txo cov kab nrib pleb stackes.

Txhim kho saum npoo av ua tiav dov cov cuab yeej thiab cov roj ua kom tsis txhob muaj cov kab xev uas nquag los tiv thaiv cov kab tawg hauv cov kav hlau steel.

⑦ Los ntawm annealing thiab kho cua sov kho lub raj dawb paug los txo cov khoom siv deformation, thiab lubrication los txo cov kab yeeb nkab yob thiab kos cov khoom tsis xws luag.
