Dab tsi yog cov txheej txheem tseem ceeb ntws ntawm seamless steel yeeb nkab ntau lawm?
Cov txheej txheem ntau lawm ntawm Seamless Steel Kave suav nrog:
Hloov BItet npaj npaj: Xaiv cov khoom siv hlau zoo dua (txuas ntxiv ua haujlwm lossis cov nqi ntim nyiaj) kom ntseeg tau tias cov kev sib xyaw ua ke.
Cov cua sov: cua sov txog 1200 ~ 1300 degree hauv lub nplhaib rhuab lossis cov txheej txheem rolling).
Pictoration: Siv tus perforator rau perforator rau perforator rau perforate ib lub zog hloov billet rau hauv lub raj uas muaj hollow hlau (Mannesmann Puloration Manquerman zoo nkauj yog hom).
Dov
Xov: Ncaj, txiav cov hau thiab tw, qhov kom pom tseeb, kev sim dej siab, thiab lwm yam.
Cov Ntsiab Lus Tseem Ceeb: Kub Rolling yog qhov tsim nyog rau loj-ntsa tuab-walled Hlav
Yuav ua li cas cov txheej txheem perforation ua tiav "khoom mus rau hollow"? Dab tsi yog cov kev nyuaj ua haujlwm?
Pleforation qauv:
Oblique dov perforation (Mannesmann Hom): Lub yob yog tilted kom ua rau lub billet tig thiab txav mus rau pem hauv ntej, thiab lub taub hau nkag mus ua lub raj hollow.
Siab Tho: Siv ib qho punch rau cov kav dej ncaj qha (siv rau cov kav hlau tuab).
Kev nyuaj:
Sab hauv phab ntsa zoo: nquag mus rau sab hauv folding thiab tawg (yuav tsum tswj kom cua sov thiab cov duab ntawm lub taub hau).
Phab ntsa thickness uniformity: kev hloov kho cov menyuam raug hloov kho yuav ua rau eccentricity.
Dab tsi yog qhov sib txawv ntawm kub dov thiab dov cov txheej txheem txias thiab dab tsi yog qhov kev siv tau tshwm sim?
Kev sib piv cov khoom kub dov txias dov \/ lub cev
Kub siab kub (saum toj recrystallization kub) ib txwm kub los yog tsawg kub
Qhov Raug Loj Loj Ntev Rau Kev Zam Txim (± 1% ~ 2%) Siab Precision (0. 1 hli)
Saum npoo muaj cov nplai oxide, yuav tsum tau ua kom du, tuaj yeem siv ncaj qha
Cov Khoom Siv Roj Them, Yeeb Yam Tsim Yeeb (Kab Hlau Loj) Hydraulic Lub Tog Raj Kheej (Kev Ntsuas Kom Zoo)
Yuav ua li cas tswj qhov tseeb qhov tseeb thiab qhov chaw zoo ntawm Seamless Steel kav?
Dimension tswj
Kub Dov
Txias kev cai: Daim pwm txhais tau txiav txim siab qhov loj me, thiab ntau daim duab hla tau maj mam tsim.
Nto Kho:
Kub-Rolled Tube: Pickling tshem oxide nplai, sandblasting los txhim kho tiav.
Txias-dov raj: polishing lossis txheej (xws li chrome plating) los tiv thaiv cov xeb.
Dab tsi yog qhov tseem ceeb txuas rau kev soj ntsuam zoo nyob rau hauv seamless steel yeeb nkab ntau lawm?
Kev kuaj xyuas qhov tsis yog: Ultrasonic Qhov Ntsuas Kom Paub Tias (UT) los xyuas sab hauv kev puas tsuaj.
Tom qab Pictoration: EDDY tam sim no kev sim (li) lossis endoscope kom kuaj cov phab ntsa sab hauv.
Cov khoom siv khoom tiav:
Tsis yog-kev sim ua phem: Ultrasonic (UT), RT) los kuaj cov kab nrib pleb thiab pores.
Kev Kuaj Me: Tensile thiab Kev Ntsuas Ntsuas kom paub tseeb lub zog.
Kev Kuaj Siab: Kev ntsuas dej siab kom paub tseeb qhov kev ntsuas lub peev xwm (xws li API tus qauv yuav tsum tau 1.5 zaug ua haujlwm siab).
