Txias dov yog hais txog kev ua cov ntawv hlau lossis cov hlau nplaum rau hauv ntau yam khoom siv hlau los ntawm kev ua haujlwm txias xws li kos duab txias, txias khoov, thiab kub kub txias txias.
Carbon steel kavtau muab faib ua ob pawg: cov kav dej kub-kuav los tiag thiab txias-dov (kos) steel kav. Cov pa roj carbon steel yeeb nkab yog tsim los ntawm steel ingots los yog khoom billets los ntawm perforating lawv mus rau hauv capillary hlab, thiab ces kub dov, txias dov los yog txias txias. Cov pa roj carbon steel kav tuav ib txoj haujlwm tseem ceeb hauv kuv lub teb chaws txoj kev lag luam steel yeeb nkab.
Cold-rolled carbon steel kav yog txias-draw los yog txias-dov precision seamless steel kav nrog siab qhov tseeb thiab zoo nto tiav siv nyob rau hauv txhua yam qauv thiab hydraulic khoom. Ntxiv nrog rau cov kav hlau zoo tib yam, cov kav dej qis thiab nruab nrab siab boiler steel kav, siab siab boiler steel kav, alloy steel kav, stainless hlau kav, roj av cracking kav thiab lwm yam steel kav, txias-dov (kos) seamless kav kuj muaj xws li carbon nyias- phab ntsa steel kav. - Nyias-walled steel kav, alloy nyias-walled steel kav, stainless hlau nyias-walled steel kav, tshwj xeeb-zoo li tus steel kav. Sab nraud txoj kab uas hla ntawm cov kav dej kub dov seamless feem ntau yog ntau dua 32 hli, thiab phab ntsa thickness yog 2.{13}}mm. Txoj kab uas hla ntawm cov yeeb nkab txias-dov seamless tuaj yeem ncav cuag 6 hli thiab phab ntsa tuab tuaj yeem ncav cuag 0.25mm. Txias dov muaj qhov tseeb qhov tseeb dua li qhov kub dov.
Kub dov steel kav yog muab faib ua cov kav hlau dav dav, qis thiab nruab nrab siab boiler steel kav, siab siab boiler steel kav, alloy steel kav, stainless hlau kav, roj av tawg kav, geological steel kav thiab lwm yam steel kav.
Ordinary carbon steel kav: kub-dov los yog txias-dov los ntawm high-zoo carbon steels xws li 10, 20, 30, 35, 45, 16Mn, 5MnV thiab lwm yam uas tsis muaj alloy structural steels, los yog 40Cr, 30CrMnSi, 45Mn2, 40MnB thiab lwm yam hlau alloys. Cov kav dej seamless ua los ntawm cov hlau tsis tshua muaj xws li No. 10 thiab No. 20 feem ntau yog siv rau cov kav dej thauj mus los. Cov pa nruab nrab carbon steel seamless kav xws li 45 thiab 40Cr yog siv los tsim cov khoom siv kho tshuab, xws li cov kev ntxhov siab ntawm cov tsheb thiab tsheb laij teb. Carbon steel kav feem ntau yog siv los xyuas kom meej lub zog thiab flattening xeem. Kub dov steel kav yog xa mus rau hauv lub kub dov los yog kub-kho lub xeev; txias-kuav los tiag steel kav yog xa nyob rau hauv lub tshav kub-kho lub xeev.
Qhov txawv ntawm txias dov thiab kub dov:
1. Cold-rolled seem steel tso cai rau hauv zos buckling ntawm seem, kom cov kabmob muaj peev xwm ntawm cov khoom tom qab buckling tuaj yeem siv tag nrho; thaum kub-kuav los tiag seem steel tsis pub lub zos buckling ntawm seem.
2. Qhov ua rau muaj kev ntxhov siab nyob hauv cov phaj kub-kuav los tiag steel phaj thiab txias-kuav los tiag steel daim hlau yog txawv, yog li qhov kev faib tawm ntawm cov ntoo hlais kuj txawv heev. Qhov seem kev ntxhov siab faib rau ntawm qhov txias-tsim nyias-walled steel seem yog nkhaus, thaum seem kev ntxhov siab faib rau ntawm qhov kub-dov los yog welded steel seem yog zaj duab xis-zoo li.
3. Qhov dawb torsional nruj ntawm cov hlau kub dov yog siab dua li cov hlau txias-dov, yog li qhov kev ua haujlwm torsional ntawm cov hlau kub dov yog zoo dua li cov hlau txias.
