Kev xeem
(1) Hydraulic xeem
Cov yeeb nkab steel yuav tsum tau kuaj hydraulically ib los ntawm ib qho.
(2) Kaj ntsuam xyuas
Cov kab hlau hlau nrog cov cheeb tsam sab nraud ntau dua 22 hli rau 400mm thiab ib phab ntsa tuab ntawm tsis ntau tshaj 10 hli yuav raug rau kev ntsuas siab.
(3) crimping xeem
Qeb 10 kauj tsheb hlau yuav raug rau kev kuaj mob crimping.
(4) Flaring xeem
Cov yeeb nkab steel nrog lub phab ntsa tuab ntawm tsis ntau tshaj 8 mm tuaj yeem raug rau kev ntsuas qhov muag nrog 30 degree, 45 degree lossis 60 degree.
(5) Kev twv dabtsi yog khoov
Cov hlau loj kav hlau nrog txoj kab uas hla ntawm tsis ntau tshaj li 22 hli yuav raug rau qhov kev xeem dabtsi
(6) Kev kuaj tsis muaj kev puas tsuaj
Raws li cov cai yuav tsum tau ntawm tus neeg yuav khoom, cov yeeb nkab steel yuav raug ultrasonically ntsuas ib los ntawm ib.
Nto Zoo
Sab hauv thiab sab nraud ntawm cov yeeb nkab steel tsis muaj cov tawg, quav, crusting lossis sib cais yuav tsum tau muab tshem tawm kiag li. Qhov tob tob tob yuav tsis pub dhau qhov kev sib txawv ntawm cov nominal phab ntsa tuab, thiab phab ntsa tiag tiag phab ntsa tuab ntawm lub tsev tu khoom yuav tsum tsis tsawg tshaj li qhov tsawg tshaj li qhov kev tso cai tsawg tshaj plaws ntawm phab ntsa.
Cov txheej txheem kev ua tau zoo
(1) Forging thiab dov
GB 3087 qib 10 steel muaj kev ua haujlwm siab zoo. Qhov pib dov kub yog 1200-1280 degree, thiab qhov kawg dov kub yog 800-850 degree, uas tuaj yeem txias los ntawm huab cua tom qab dov (forging).
(2) Ua Haujlwm Txias
GB 3087 Qeb 10 Steel muaj zoo heev zoo, uas tuaj yeem rub tau zoo, punched, punically chim siab thiab nthuav dav nyob rau hauv lub xeev txias.
(3) Kev kho cua sov
GB 3087 qib 10 seamless steel yeeb nkab feem ntau yog siv nyob rau hauv kub dov lub xeev, thiab txias drawn (dov) steel yeeb nkab yog siv nyob rau hauv kev kho cua sov lub xeev. Kev kho cua sov feem ntau yog siv, thiab qhov normalizing kub yog 900-940 degree .
(4) vuam
Lub Heldability ntawm GB 3087 Qeb 10 steel yog qhov zoo, thiab feem ntau muaj tsis muaj kev ua kom tawv. Thaum nws tsim nyog rau vuam thiab tsim cov khoom cua kub boiler cua sov qhov chaw los ntawm ntau hom vuam siv lossis cov pa thaiv cov vuam thiab lwm txoj kev vuam. E4303 (J422) thiab E4315 feem ntau siv rau kev siv ntaub vuam. Tsis muaj preheating ua ntej vuam thiab tsis muaj kev kho cua sov tom qab vuam.
