Kev Tshuaj Xyuas: Feem ntau, cov kav hlau rau kev thauj mus los ntawm cov kua dej yuav tsum tau dhau los ntawm kev tshuaj xyuas cov tshuaj lom neeg, kev sim tensile, kev sim flattening thiab kev sim siab dej. Ntxiv rau qhov kev sim uas yuav tsum tau ua rau cov kav hlau rau kev thauj mus los ntawm cov kua dej, cov kav hlau ntawm GB5310, GB6479 thiab GB9948 kuj yuav tsum tau dhau los ntawm kev sim nthuav dav thiab kev sim cuam tshuam; cov kev cai tshuaj xyuas kev tsim khoom rau peb cov kav hlau no yog qhov nruj heev. GB6479 tus qauv kuj ua rau muaj kev cai tshwj xeeb rau qhov kub qis cuam tshuam ntawm cov ntaub ntawv. Ntxiv rau qhov kev cai kuaj dav dav rau cov kav hlau rau kev thauj mus los ntawm cov kua dej, cov kav hlau ntawm GB3087 tus qauv kuj yuav tsum tau dhau los ntawm kev sim khoov txias. Ntxiv rau qhov kev cai kuaj dav dav rau cov kav hlau rau kev thauj mus los ntawm cov kua dej, cov kav hlau ntawm GB/T8163 tus qauv yuav tsum tau dhau los ntawm kev sim nthuav dav thiab kev sim khoov txias raws li daim ntawv cog lus. Cov kev cai tsim khoom rau ob lub kav dej no tsis nruj npaum li peb thawj zaug. Kev Tsim Khoom: Cov kav hlau ntawm GB/T/8163 thiab GB3087 tus qauv feem ntau yog smelted los ntawm lub qhov cub qhib-hearth lossis converter, thiab lawv cov khoom tsis huv thiab cov qhov tsis zoo sab hauv yog qhov ntau dua. GB9948 feem ntau yog siv hluav taws xob los ua kom sov. Feem ntau ntawm lawv tau ntxiv cov txheej txheem ua kom sov sab nraum lub cub tawg, thiab cov khoom sib xyaw thiab cov qhov tsis zoo sab hauv tsawg dua. GB6479 thiab GB5310 cov qauv lawv tus kheej teev cov kev cai rau kev ua kom sov sab nraum lub cub tawg, nrog rau cov khoom tsis huv thiab cov qhov tsis zoo sab hauv tsawg tshaj plaws, thiab cov khoom zoo tshaj plaws. Cov qib zoo ntawm cov yeeb nkab hlau saum toj no yog raws li qhov kev txiav txim los ntawm qis mus rau siab: GB/T8163
(II) Cov kav hlau tsis muaj hlau sib xyaw ua ke Hauv cov khoom siv petrochemical, cov qauv yeeb nkab hlau tsis muaj hlau chromium-molybdenum thiab chromium-molybdenum-vanadium feem ntau siv yog GB9948 "Cov kav hlau tsis muaj hlau rau kev tawg roj av" GB6479 "Cov kav hlau tsis muaj hlau siab rau cov khoom siv chiv" GB/T5310 "Cov kav hlau tsis muaj hlau rau cov boilers siab" GB9948 muaj cov khoom siv hlau chromium-molybdenum qib: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, thiab lwm yam. GB6479 muaj cov khoom siv hlau chromium-molybdenum qib: 12CrMo, 15CrMo, 1Cr5Mo, thiab lwm yam. GB/T5310 muaj cov hlau chromium-molybdenum thiab cov khoom siv hlau chromium-molybdenum-vanadium qib: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, thiab lwm yam. Ntawm lawv, GB9948 feem ntau siv, thiab cov xwm txheej xaiv yog raws li saum toj no.
