Kev siv cov yeeb nkab hlau tuaj yeem muaj qee yam kev cuam tshuam yog tias lawv siv nyob rau hauv ib qho kev ncua deb, tab sis nyob rau hauv qee qhov chaw, nws tsis zoo siv rau qee yam tshwj xeeb, xws li hauv qee qhov chaw muaj tshuaj lom vim yog cov khoom siv raw. ntawm seamless steel kav, yog tias siv mus ntev, cov kav hlau kav hlau yuav yog vim corrosion.Yog tias cov kav hlau kav siv ib leeg, lawv yuav muaj teeb meem, tab sis cov kav hlau kav hlau yuav muaj qee qhov kev saib xyuas xwm txheej ceev.Tom qab no, peb yuav tsum tau meej heev.Txhawm rau tswj nws, nrog rau qhov nce ntawm hydrogen cov ntsiab lus ntawm billet, qhov tsim nyog tus nqi ntawm qhov tsis txaus ntseeg tau maj mam txo qis.Thaum cov ntsiab lus hydrogen nyob rau hauv lub billet ntau dua (4-5) × 10-6, tus nqi tsim nyog ntawm cov phaj hlau rau qhov tsis pom kev poob qis, thiab cov ntsiab lus hydrogen hauv lub billet tsawg dua Thaum (2～3) × 10-6, qhov tsim nyog tus nqi ntawm cov hlau phaj tsis pom kev yog 100%.Tshwj xeeb, nws tuaj yeem tsim qhov pores, ua rau cov kab nrib pleb ntau dua, thiab txo qis cov cuab yeej ntawm cov hlau xws li lub zog, plasticity, qaug zog lub neej thiab cuam tshuam toughness.
Kev tshawb fawb qhia tau hais tias ntev npaum li cov ntsiab lus hydrogen hauv cov hlau qis dua 2.0 × 10-6, yuav tsis muaj cov pob dawb, tab sis nrog kev poob qis ntawm cov ntsiab lus sulfur hauv cov hlau, lub tshuab ua ntej lub tshuab ntsuas hluav taws xob tau txais kev tiv thaiv. -electromagnetic cuam tshuam, plua plav-pov thawj, ultra-thin portable tsim, Kev ua haujlwm yooj yim, tsis yog cov kws tshaj lij tuaj yeem ua haujlwm tom qab kev cob qhia luv luv, thiab tuaj yeem txuas nrog lwm yam khoom siv hluav taws xob.Muaj ntau txoj kab kev tshawb nrhiav, thiab cov kab uas tsim nyog nrhiav tau raug xaiv rau cov hlau molten ntawm cov npe sib txawv thiab qhov xwm txheej tiag tiag ntawm cov hlau molten nyob rau hauv txhua lub Hoobkas, kom qhov kev tshawb pom muaj ntau qhov kev tshawb fawb thiab raug.
Cov kav hlau kav dej suav nrog ntau dua 80% ntawm Tuam Tshoj cov kav dej hauv nroog.Nyob rau hauv xyoo tas los no, cov kav dej grey cam khwb cia hlau tau maj mam tshuaj xyuas, thiab siv ntau cov kav hlau kav.Nyob rau hauv xyoo tas los no, cov khoom tsim tawm txhua xyoo thiab kev lag luam ntawm Tuam Tshoj cov kav hlau cam khwb cia yog li 3.5 lab tons, centrifugal grey cam khwb cia hlau cov kav dej yog li 800,000 tons, thiab ntau yam cam khwb cia hlau yeeb nkab fittings yog li 200,000 tons.
