Dab tsi yog boiler steel yeeb nkab?
Boiler steel raj xa mus rau cov khoom siv hlau uas qhib rau ntawm ob qho kawg thiab muaj cov seem hollow nrog qhov ntev ntev txheeb ze rau thaj tsam ib puag ncig. Raws li txoj kev tsim khoom, lawv tuaj yeem muab faib ua seamless steel kav thiab welded steel kav. Cov kev qhia tshwj xeeb ntawm cov kav dej steel yog txiav txim siab los ntawm qhov ntev ntawm sab nraud (xws li sab nraud lossis sab ntev) thiab phab ntsa tuab yog qhia ntau qhov ntau thiab tsawg, los ntawm cov hlab capillary nrog cov kab me me mus rau cov kab loj loj nrog txoj kab uas hla ntawm ob peb meters. Cov kav hlau hlau tuaj yeem siv rau hauv cov kav dej, cov khoom siv thermal, kev lag luam machinery, roj av geological tshawb nrhiav, ntim, kev lag luam tshuaj, thiab cov hom phiaj tshwj xeeb.

Kev siv ntawm boiler steel kav:
Cov kav dej siv hauv kev lag luam boilers feem ntau yog seamless steel kav vim qhov ntsuas kev ua tau zoo ntawm seamless steel kav tuaj yeem ua tau raws li qhov xav tau ntawm kev siv boiler. Txawm hais tias tus nqi siab, lawv txoj kev nyab xeeb thiab kev ntseeg siab yog siab. Welded steel kav feem ntau yog siv los ua cov kav dej uas tsis tshua muaj siab hauv 2Mpa. Cov khoom siv kub thiab kub siab xws li kev lag luam boilers yuav tsum siv seamless steel kav, thiab lub thickness ntawm cov yeeb nkab phab ntsa yog correspondingly thickened. Welded steel kav tam sim no kuj tau siv nyob rau hauv nruab nrab thiab qis-siab boilers, ua tsaug rau kev txhim kho sai ntawm vuam tshuab. Piv txwv li, thaum cov kav dej yog pob tw-welded rau kev sib txhuam-welded steel kav, microstructure ntawm cov pob qij txha tsis txawv. Ntxiv mus, tom qab cov yeeb nkab seams remelted los ntawm pob qij txha thiab kaum pob qij txha, nws yog ib qho nyuaj rau soj ntsuam cov seam marks nrog lub qhov muag liab qab. Lub microstructure ntawm nws qhov chaw tau dhau los ua tib yam li kev sib txhuam-welded steel kav. Nws zoo ib yam li ntawm seam.
