1. Vim li cas cov ntsiab lus qis carbon zoo dua rau vuam?
Cov hlau me me muaj cov pa roj carbon tsawg, txhais tau tias nws tsis tshua muaj peev xwm tsim cov qauv martensitic nyuaj thiab nkig thaum txias tom qab vuam. Qhov no txo qhov kev pheej hmoo ntawm kev tawg thiab ua rau nws zoo tagnrho rauERW (Electric Resistance Welded) kav, automotive ncej, thiabcov khoom seem.
2. Cov pa roj carbon monoxide cuam tshuam li cas rau cov cua sov thiab cua txias?
Cov pa roj carbon-nplua nuj steels yuav tsum tau ceev faj tswjpreheat thiab interpass kubtiv thaiv hardening nyob ze ntawm qhov chaw weld. Cov hlau me me tuaj yeem welded ntawm chav tsev kub yam tsis muaj kev ceev faj tshwj xeeb, txuag lub sijhawm thiab nqi.
3. Puas muaj kev lag luam -Tawm ntawm Weldability thiab Strength?
Yog lawm. Cov pa roj carbon ntau dua muaj zog dua tab sis nyuaj rau vuam. Cov hlau me me yog yooj yim rau kev koom nrog tab sis muaj zog tensile qis. Yog vim li casERW me me steel kavyog nrov nyob rau hauvkev tsim kho thiab kev xa dej, qhov twg weldability yog qhov tseem ceeb tshaj qhov muaj zog heev.
Yuav ua li cas vuam kev ua tau zoo sib txawv ntawm me me thiab carbon hlau?
Vuam tus cwj pwm yog ib qho tseem ceeb tshaj plaws thaum xaiv cov khoom siv rau kev tsim khoom lossis kev sib koom ua ke. Cia peb tshawb nrhiav cov laj thawj mechanical thiab metallurgical tom qab qhov sib txawv no.
1. Vim li cas Mild Steel tso cai rau fusion yooj yim dua?
Vim nws cov ferritic microstructure, me me hlau melts tusyees nyob rau hauv arc los yog kuj kub. Qhov no ua rau cov hlaws du weld nrog tsawg porosity lossis tawg. Nyob rau hauv sib piv, carbon steel qhov nyuaj microstructure yuav ua rau lub zos melting, distortion, los yog tsis tiav fusion.
2. Txoj kev vuam twg yog qhov zoo tshaj plaws rau txhua hom?
| Hom hlau | Pom zoo Vuam txoj kev | Cov kev ceev faj |
|---|---|---|
| Mild Steel | ERW, MIG, TIG, welding | Tsawg kawg yuav tsum tau preheat |
| Nruab nrab Carbon Steel | SMAW, TIG | Preheat rau 150-250 degree |
| High Carbon Steel | TIG, Oxy-fuel | Preheat thiab tom qab-kub tseem ceeb |
3. Cov Hlau Me Me puas tuaj yeem tuav rov qab vuam thiab kho dua?
Yog lawm. Cov hlau me me zam ntau lub voj voog vuam thiab rov ua haujlwm dua, ua rau nws zoo meej rau cov qauv loj thiab cov kav dej uas yuav tsum tau sib dhos ntawm qhov chaw - qhov laj thawj tseem ceebHuayang steel yeeb nkabua hauj lwmERW thiab SAWL cov txheej txheemrau qhov sib xws, txhim khu kev qha weld pob qij txha.
Vim li cas Mild Steel yooj yim rau kev tsim thiab khoov?
1. Ductility cuam tshuam li cas rau kev tsim?
Cov hlau me mecov pa roj carbon tsawgthiabsiab ductilitycia nws deform plastically yam tsis muaj cracking. Qhov no ua rau nws zoo tagnrho raucev dov, txias tsim, thiabkhoovkev ua haujlwm - cov kauj ruam tseem ceeb hauv kev tsim khoomERW steel kavthiabstructural profiles.
| Tsim Khoom | Mild Steel | Carbon Steel |
|---|---|---|
| Elongation (%) | 25–30 | 10–15 |
| Yam tsawg kawg nkaus Khoov Radius | Me me | Loj dua |
| Ua Haujlwm Hardening | qeeb | Ceev ceev |
