Cov Yeeb Nkab Hlau Phab Ntsa tuab
Cov yeeb nkab hlau muaj ib ntu hollow thiab siv ntau heev ua cov kav dej rau kev xa cov kua, xws li cov kav dej rau kev xa roj, roj av, roj, dej thiab qee yam khoom khov. Piv nrog cov hlau khov xws li hlau puag ncig, cov yeeb nkab hlau alloy sib dua thaum lub zog khoov thiab torsion zoo ib yam. Cov yeeb nkab hlau alloy yog ib hom hlau hla ntu pheej yig, uas siv dav hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li cov yeeb nkab roj tho thiab kev sib kis tsheb. Cov axes, cov thav duab tsheb kauj vab thiab cov scaffolding hlau siv hauv kev tsim kho tsev, thiab lwm yam. Kev siv cov yeeb nkab hlau alloy los tsim cov khoom siv nplhaib tuaj yeem ua rau kom muaj kev siv cov khoom siv ntau dua, ua kom yooj yim rau cov txheej txheem tsim khoom, txuag cov khoom siv thiab cov sijhawm ua haujlwm, xws li cov nplhaib dov, cov tes tsho jack, thiab lwm yam, uas tau siv dav hauv kev tsim cov yeeb nkab hlau. Cov yeeb nkab hlau alloy kuj yog cov khoom siv tseem ceeb rau ntau yam riam phom ib txwm muaj. Cov thoob phom thiab cov thoob phom yog ua los ntawm cov yeeb nkab hlau. Cov yeeb nkab hlau alloy tuaj yeem faib ua cov yeeb nkab puag ncig thiab cov yeeb nkab zoo li tshwj xeeb raws li cov duab sib txawv ntawm thaj chaw hla ntu. Txij li thaj chaw voj voog yog qhov loj tshaj plaws hauv qhov xwm txheej ntawm qhov sib npaug, ntau cov kua tuaj yeem thauj los ntawm lub raj voj voog. Tsis tas li ntawd xwb, thaum lub nplhaib raug rau sab hauv lossis sab nraud radial siab, lub zog yog sib npaug zos. Yog li ntawd, feem ntau ntawm cov kav hlau yog cov kav puag ncig.
Kev faib tawm ntawm cov kav dej hlau tuab-phab ntsa
Qhov zoo tshaj plaws ntawm cov kav dej hlau tuab yog tias lawv tuaj yeem rov ua dua 100%, uas yog raws li lub teb chaws txoj kev tiv thaiv ib puag ncig, txuag hluav taws xob, thiab txuag cov peev txheej. Txoj cai hauv teb chaws txhawb kom nthuav dav ntawm thaj chaw siv ntawm cov kav dej hlau tuab.
Txheej txheem cej luam
Kub dov (extruded seamless steel tube): lub raj kheej kheej kheej → cua sov → tho → peb-yob hla dov, txuas ntxiv dov lossis extrusion → tshem tawm lub raj → sizing (lossis txo) → txias → lub raj kheej kheej kheej → ncaj → dej siab Sim (lossis qhov tsis zoo nrhiav) → cim → chaw cia khoom.
Cov yeeb nkab hlau tsis muaj qhov txuas: lub raj kheej kheej kheej → cua sov → tho → taub hau → annealing → pickling → oiling (tooj liab plating) → ntau-pass txias kos duab (txias dov) → raj billet → kho cua sov → ncaj → Kev sim siab dej (qhov tsis zoo nrhiav) → cim → chaw khaws khoom.
1XXX alloy series raws li txhuas ntshiab.
2XXX Txhuas hlau nrog tooj liab ua lub ntsiab alloying.
3XXX Aluminium alloy nrog manganese ua lub ntsiab alloying.
Kev siv cov raj titanium alloy: Cov raj titanium alloy feem ntau yog siv rau hauv kev tsav dav hlau. Nws yog ib hom raj alloy tshwj xeeb uas siv rau kev tsav dav hlau nrog kev tawv thiab kub siab.
4XXX Aluminium alloy nrog silicon ua lub ntsiab alloying.
5XXX Aluminium alloy nrog magnesium ua lub ntsiab alloying.
6XXX Aluminium alloy nrog magnesium thiab silicon ua cov ntsiab lus tseem ceeb ntawm alloying.
7XXX Aluminium alloy nrog zinc ua lub ntsiab alloying.
Cov qauv hnyav ntawm cov yeeb nkab hlau:[(Txoj kab uas hla sab nraud-qhov tuab ntawm phab ntsa)*qhov tuab ntawm phab ntsa]*0.02483=kg/m2 (qhov hnyav ib 'meter')
