DIN1629, EN10210, EN10216, A53 Cov Txheej Txheem QuavXa mus rau tubular cov khoom lag luam siv hauv kev tsim kho cov qauv kom dais loads thiab wigstand nias. Tiv rau lawv cov khoom lag luam zoo tshaj plaws - Cov kabmob muaj peev xwm thiab kev ruaj khov, cov kav dej tau siv nyob rau hauv ntau txoj haujlwm tsim kho thiab engineering.
Cov khoom siv thawj rau cov txheej txheem kev teeb tsa yog feem ntau hlau, uas undergoes tshwj xeeb ua thiab kho cov kev kho mob kom ua tiav thiab tensile lub zog. Qhov no ua rau lawv ua kom tau kev tawm tsam sab nraud, kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov tsev.
Dhau ntawm lawv cov load yooj yim - cov kabmob hlab kuj tseem ceeb ua kom zoo nkauj thiab weldability, muab siab rau kev tsim kho. Lawv tuaj yeem ua tau zoo li thiab txuas tau los rau ntau yam kev tsim qauv. Ib qho ntxiv, cov qauv hlab teeb tsa lub neej ntev ntev, kev ua kom muaj kev ua tau zoo txawm tias ib puag ncig hnyav, ua rau lawv tsis muaj cov khoom siv hauv kev tsim kho.

Txheej Txheem Txheej Txheem Txheej Txheem
I. Raw Khoom Batching
Cov Khoom Siv Hluav Taws Xob Hlau yog cov khoom lag luam tseem ceeb hauv kev lag luam steel, feem ntau ua los ntawm high- zoo} Cov hlau ua khoom zoo. Ua ntej, cov ntses tau pub rau hauv lub tshuab batching thiab sib xyaw nrog cov khoom nyoos xws li limestone, hlau oxide, thiab carbon rau hauv cov proportionic. Qhov sib tov yog tom qab ntawd thauj mus rau ib lub moj tej tawg rau cua sov kom sov, tsim tej tawg ntub cua thiab ntshiab hlau.
Ii. Dov
Lub moj tej tawg ua kom sov slag thiab ntshiab hlau yog ua ke thiab ntxiv ua kom zoo dua los tsim cov khoom lag luam hlau. Tom qab preheating, lub billets nkag rau rolling mills, uas lawv tau dov rau hauv tsim steel kav dej nyob rau hauv kub siab thiab siab. Tus yuam sij rau cov txheej txheem no nyob rau hauv qhov precision thiab tswj lub peev xwm ntawm Rolling million ntawm qib no tuaj yeem lav tau qhov zoo ntawm cov txheej txheem tom ntej.
III. Pickling
Tom qab dov mus rau hauv tsim cov kav dej, kev kho mob pickling yog ua. Cov kauj ruam no feem ntau tshem tawm saum npoo oxides thiab xeb kom ntseeg tau tias kev nce qib du hauv cov txheej txheem txias. Thaum lub sij hawm pickling, acids, alkalis, thiab lwm cov neeg ua kom huv yog siv los ua tiav qhov chaw ua kom tiav.
IV. Lub cev tsis huv
Tom qab pickling, cov pipes tsim nkag rau chav kuaj txias rau kev ua. Nyob rau hauv cov txheej txheem no, tshuab ncab cov hlau hais hauv cov yeeb nkab kom txo nws txoj kab uas hla thaum ua kom tiav cov khaub ncaws zoo ntau dua. Qhov tseem ceeb ntawm no yog nyob hauv lub tshuab kev ua haujlwm thiab kev ua haujlwm {{May} Mastery ntawm ua kom pom tseeb qhov tseeb thiab zoo hauv cov khoom kawg.
V. Kev Kho Tshav Kub Kub
Tom qab kos duab txias, cov kav dej tsim tawm hauv kev kho cua sov. Cov kauj ruam no ua rau kho qhov loj me thiab qauv ntawm cov hlau hlau sab hauv kom tau raws li kev ua kom tau raws li lub hardness, kev nruj, thiab lwm cov khoom siv mechanical, thiab lwm yam khoom siv mechanical, thiab lwm yam khoom siv mechanical, thiab lwm cov khoom siv mechanical, thiab lwm cov khoom siv mechanical, thiab lwm yam khoom siv mechanical, thiab lwm yam khoom siv neeg kho mob. Cov txheej txheem kev kho cua sov muaj xws li cua sov, so kom meej, thiab txias tswj tau qhov kub thiab txias, lub sijhawm, thiab lwm yam khoom siv kom ntseeg tau zoo.
