wb 8162thiab GB8163 yog ob qhov sib txawv tshwj xeeb rau seamless steel kav hauv Suav teb cov qauv. Lawv muaj qhov sib txawv tseem ceeb hauv kev siv, kev xav tau, kev soj ntsuam cov qauv, thiab lwm yam Cov hauv qab no yog cov ncauj lus kom ntxaws sib piv ntawm qhov sib txawv tseem ceeb:
1. Tus qauv lub npe thiab thaj tsam ntawm daim ntawv thov
Lub npe: "Seamless Steel Yeeb Nkab Rau Kev Siv"
Siv: Feem ntau yog siv rau hauv cov qauv dav dav, kev siv tshuab thiab lwm yam kev thauj mus los tsis yog kua, xws li kev txhawb nqa lub tsev, cov khoom siv tshuab, thiab lwm yam.
Cov xwm txheej siv tau: qee lub sijhawm nrog cov khoom zoo li qub lossis cov khoom siv kho tshuab, tsis haum rau kev thauj mus los ntawm cov dej siab lossis cov kua dej.
Lub npe: "Seamless Steel Yeeb Nkab rau Kev thauj mus los"
Siv: Tsim los rau kev xa cov kua dej (xws li dej, roj, roj, thiab lwm yam), feem ntau siv hauv cov kav dej siab xws li roj av, tshuaj, boilers, thiab lwm yam.
Cov xwm txheej siv tau: Yuav tsum tau tiv taus qee qhov kev kub ntxhov thiab kub, thiab muaj kev ruaj ntseg siab
2. Cov khoom siv thiab tshuaj lom neeg muaj pes tsawg leeg
GB8162:
Cov khoom siv:20#, 45 #, q345 ibthiab lwm yam zoo tib yam carbon steel los yog tsawg alloy steel.
Cov tshuaj muaj pes tsawg leeg yuav tsum tau xoob, tsom rau cov khoom siv kho tshuab (xws li lub zog tensile, yield zog).
GB8163:
Cov khoom siv: 20 #, 16Mn, Q345B, thiab lwm yam., weldability zoo thiab siab tsis kam yuav tsum tau lav.
Cov ntsiab lus ntawm cov khoom tsis zoo xws li sulfur (S) thiab phosphorus (P) yog tswj hwm nruj dua kom muaj kev nyab xeeb ntawm kev thauj mus los ntawm cov dej.
3. Mechanical Performance Requirements
GB8162:
Tsom ntsoov rau cov khoom siv kho tshuab xws li tensile lub zog thiab elongation kom tau raws li cov qauv kev thauj khoom-cov kabmob.
Kev cuam tshuam toughness lossis kev ntsuas kub ua haujlwm siab feem ntau tsis tas yuav tsum tau ua.
GB8163:
Ntxiv nrog rau lub zog tensile, kev ntsuas dej siab, kev ntsuas kev nthuav dav, kev ntsuam xyuas flattening, thiab lwm yam yuav tsum tau ua kom ntseeg tau tias cov yeeb nkab steel tsis muaj dej los yog deformation nyob rau hauv siab.
Qee qhov kev ua haujlwm yuav tsum tau ua kom muaj kev kub ntxhov ntxiv lossis ntsuas qhov ntsuas kub tsawg.
4. Kev ntsuas siab
GB8162:
Kev ntsuas hydraulic feem ntau tsis tas yuav tsum tau ua (tshwj tsis yog pom zoo hauv daim ntawv cog lus).
GB8163:
Hydraulic siab test (los yog tsis-destructive testing) yuav tsum tau ua los xyuas kom meej lub siab bearing muaj peev xwm.
5. Cov txheej txheem tsim khoom thiab tshuaj xyuas
GB8162:
Cov txheej txheem tsim khoom (kub dov, kos duab txias) tuaj yeem ua tau raws li cov qauv kev cai dav dav.
Muaj tsawg dua cov khoom soj ntsuam, feem ntau suav nrog qhov loj me, qhov zoo ntawm qhov chaw, thiab cov khoom siv kho tshuab.
GB8163:
Cov txheej txheem tsim khoom yuav tsum tau ua kom muaj kev sib txig sib luag thiab ntom ntom (xws li nruam casting lossis refining sab nraum lub cub tawg).
Kev tshuaj xyuas yog nruj dua, nrog rau kev kuaj tsis muaj kev puas tsuaj xws li kev ntsuas tam sim no thiab kuaj ultrasonic (nyob ntawm lub hom phiaj).
6. Kev kos npe thiab ntawv pov thawj
GB8162: Tus qauv naj npawb, khoom siv, specification, thiab lwm yam yuav tsum tau muab cim rau hauv lub cim, tab sis tsis muaj ntawv pov thawj tshwj xeeb.
GB8163: Daim ntawv pov thawj ntxiv rau cov kav xa dej siab (xws li daim ntawv tso cai khoom tshwj xeeb) yuav tsum tau.
Nco tseg:
Kev sib xyaw yog txwv nruj: GB8163 steel kav tuaj yeem siv rau kev tsim qauv (yuav tsum ua raws li GB8162 cov cai), tab sis GB8162 steel kav tsis tuaj yeem hloov GB8163 rau kev thauj mus los, txwv tsis pub yuav muaj kev nyab xeeb.
