Thaum tshav kub kub tooj: nws yog ib tug steel smelting rauv naj npawb ntawm lub sij hawm nrog tshwj xeeb, traceability.Cov mills sib txawv muaj cov lej sib txawv, tab sis txhua qhov cub hlau yuav tsum yog tus lej.

Thaum tshav kub kub yog muab faib ua rauv tooj thiab batch tooj, lub cub tawg "txhais tau hais tias lub cub tawg qhov twg cov txheej txheem steel;"batch" yog hais txog lub cub tawg nrog tib qhov loj ntawm lub phaj.

Hlau yeeb nkab kub toojyog tus kheej.Rauv steelmaking furnace tank tooj yog hais txog tus naj npawb ntawm txhua qhov kev tshuaj ntsuam yuav tsum ua lub cub tawg, lub cub tawg steel yug tus lej yog qhov zoo.Batch tooj yog kev kho cua sov ntawm steel daim ntawv lo.Mechanical tsom xam ntawm txhua batch ntawm cov khoom yuav tsum tau ua, txheej txheem kev ua tau zoo tours.batch yog pov thawj steel kev loj hlob.

Lub cub tawg tuaj yeem muab faib ua ob peb pawg, tib tus naj npawb ntawm tib lub batch ntawm steel rauv tuaj yeem sib txawv qhov ntau thiab tsawg, tab sis cov khoom siv tsis yog tib theem yuav tsum yog tib lub phaj.Cov khoom sib txawv ntawm tib lub tshav kub daim hlau tuaj yeem sib txawv qhov ntau thiab tsawg, tab sis cov khoom siv tsis yog tib theem yuav tsum yog tib yam batch tooj phaj yog yooj yim heev, xws li API 5L Gr.b, ntau lub tuam txhab muaj cov khoom siv no, yeej muaj ntau. ntawm kev tsim tawm ntawm qhov cub, thiab tom qab ntawd xa khoom thaum tsim nyog xa los ntawm cov khoom siv, txhua batch yuav muaj tus lej rog.Yog li ntawd, tib batch tooj, sib txawv ntawm cov cua sov yuav zoo li, tab sis yog tias muaj teeb meem zoo, koj tuaj yeem muab tso rau ntawd los xyuas qhov teeb meem ntawm qhov cub.Ib yam li cov khoom siv hluav taws xob, txhua qhov cub hauv cov txheej txheem, qhov kev tso cai yuav muaj qee qhov sib txawv me me tuaj yeem muaj lub tshuab hluav taws xob, nrog rau kev kho cua sov kom zoo: kev kho cua sov nrog rau tus lej suav.Quenched: Txhua pab pawg neeg ua haujlwm (ib pawg ntawm ntau tshaj ib qho kev txiav tuaj yeem txiav txim siab).
