JIS G3115 SPV490Q Siab Vessel Steel
SPV490 steel phaj yog Japanese tus qauv steel phaj rau cov hlab ntsha siab, uas yog cov hlau tsis tshua muaj siab zog steel. Cov hlau phaj muaj lub zog siab, zoo toughness, tsis tshua muaj vuam tawg rhiab heev thiab corrosion kuj. Nws yog tsuas yog siv rau kev tsim cov roj av cia tank. Vertical cia tso tsheb hlau luam yog cov thawv loj sib sau ua ke thiab welded rau ntawm qhov chaw, thiab qhov vuam zoo ntawm nws cov welds ncaj qha txiav txim siab qhov ua tau zoo thiab lub neej ntawm cov tso tsheb hlau luam, uas feem ntau welded siv high -kev siv tshuab vuam tshuab.

SPV490Q steel boiler phaj kub kho cov txheej txheem cuam tshuam
1, SPV490Q siab lub nkoj phaj tsim los ntawm cov txheej txheem quenching ncaj qha muaj lub zog zoo thiab qhov sib txuam, cov txheej txheem tuaj yeem hloov cov tsoos tawm - cov txheej txheem kev hloov kho, kom ua tiav lub zog txuag thiab txo cov nqi.
2, ncaj qha quenching ntawm steel phaj tempering lub zog poob yog me me, kev txhim kho toughness yog pom tseeb; reheat quenched steel phaj rau tempering, lub zog yuav poob ntau heev. Toughness thiab plasticity txhim kho, qhov qub tau zoo dua tempering tsis kam.
3, ncaj qha quenching kom tau lub siab dislocation ceev lath martensitic lub koom haum, nws martensitic lath zoo dabtsi yog khoov thiab hla ib leeg. Reheating quenched steel kom tau ib qho qis dislocation ceev martensite lub koom haum, martensite slats thicker.
4, nyob rau hauv tib lub tempering tej yam kev mob, ncaj qha quenched steel phaj nag lossis daus ntawm carbides me me thiab diffuse tis, thiab reheat quenched steel phaj nag lossis daus ntawm carbides ntau ntxhib.
