Cov txheej txheem ntau lawm
Raw Khoom Npaj
1. Cov khoom yuav tsum tau xaiv
Raws li EN 10217, cov kav dej hlau yuav tsum yog cov qib tshwj xeeb ntawm cov hlau, xws li cov hlau me me, hlau lossis hlau s235jrh, s275j2h, thiab lwm yam). Cov khoom siv raw yuav tsum tau twv cov khoom siv tshuaj lom neeg tshuaj ntsuam thiab cov kws ua haujlwm ntsuas kev ntsuas kom ntseeg tau tias lawv ua tau raws li lub zog tshwj xeeb thiab kom muaj zog.
2. Pretreatment ntawm Billet
Txiav, txiav thiab ntxuav cov npoo ntawm cov hlau phaj lossis cov txaij tshem tawm impurities xws li oxide, roj, thiab npaj rau tom ntej molding thiab vuam.
Txoj kev sib txuas thiab vuam
1. Dov moulding
Tus txheej txheem stip yog ib tug neeg tsis muaj kev sib koom tes thiab xa mus rau txoj kev sib sau tshuab rau txuas ntxiv mus rau hauv lub tog raj kheej. Cov kauj ruam no yuav tsum tswj hwm lub ntsej muag molding thiab siab kom ntseeg tau tias qhov sib dhos ua yuam kev ntawm cov yeeb nkab yog nyob rau hauv cov qauv txheem.
2. VUAM Txheej Txheem
High-zaus Refinance vuam (HFW) lossis submerged arc vuam (muab cov weld txuas ntxiv, tso cov hws tsis tu ncua.
- Tom qab welding-welding kev kho mob: tshem tawm cov vuam slag thiab burr ntawm sab hauv thiab sab nraud thiab siv cov neeg kho kom huv si los xyuas kom muaj qhov chaw du ntawm Weld.
Kev Kho Cua Sov Thiab Ncaj Ncees
1. Cov txheej txheem kho cua sov
Nyob ntawm cov khoom siv thiab kev siv, cov yeeb nkab steel yuav tsum tau ua qhov qub, analealed lossis quenched + tempered. Piv txwv li, carbon steel feem ntau yog li qub kom tshem tawm cov kev ntxhov siab thiab txhim kho cov hlau ua kom nruj, lub sijhawm alloy hlau yuav xav tau cov txheej txheem kev kho mob kub ntau dua.
2. Ua ncaj thiab sizing
Qhov ncaj ntawm cov yeeb nkab steel yog kho los ntawm ntau txoj hlab strawb, thiab cov txheej txheej sab nraud yog tswj kom tau zoo los ntawm lub sizing pob zeb, nrog rau kev thev naus laus zis nyob rau hauv en 10217.
Nto Kho thiab tshuaj xyuas
1. Pickling thiab Txheej
Cov yeeb nkab steel yog pickled kom tshem tawm cov txheej oxide, thiab cov xeb tsis kam yog txhim kho los ntawm phosphatating, galvanizing lossis txau (nyob ntawm daim ntawv thov).
2. Cov kev sim ua txhaum cai (ndt)
- Kev tshawb nrhiav Ultrasonic (T): siv los tshawb xyuas sab hauv kev tsis xws hauv welds thiab cov khoom siv hauv paus.
- Eddy kev sim tam sim no (li): Tsim nyog rau kev ntsuam xyuas sai sai ntawm cov nrej tawg thiab pores.
- HYDRAULIC TEST: Kev ntsuas siab yog nqa tawm raws li cov qauv kev cai kom txheeb xyuas cov kabmob muaj peev xwm ua tau cov yeeb nkab.
Kev kuaj thiab cim ntawm cov khoom tiav
1. Cov khoom kuaj kawg
Suav nrog qhov ntev ntev, nto kom zoo, tshuaj lom neeg sib tw rov ua dua, tshuaj ntsuam, cuam tshuam), thiab lwm yam.
2. Kev Qhia Npe thiab Ntim
Raws li cov cai ntawm EN 10217, cov yeeb nkab steel yuav tsum tau cim tas mus li thiab lwm yam ntaub ntawv, thiab hnab ntawv yas lossis ntim khoom siv rau kev puas tsuaj.
Cov Lus Qhia Ntxiv
- EN 10217 muaj qhov yuav tsum ua kom nruj yuav tsum muaj vuam kev tshuaj xyuas (WPQR) thiab cov kws kho txuj ci tsim nyog, xav tau cov qauv pov thawj ua pov thawj.
- Tshwj xeeb tshwj xeeb steel kav dej (xws li qhov chaw qis lossis qhov chaw kub siab) yuav xav tau kev cuam tshuam ntxiv cov kev ntsuas nruj lossis kev ntsuas xim hlau.
