Cov laj thawj rau kev tawg ntev ntawm cov kav dej tuab-walled seamless steel kav yog los ntawm ntau yam, nrog rau cov yam ntxwv ntawm raw cov ntaub ntawv thiab cov yam ntxwv ntawm kev siv tshuab. Yog hais tias cov tuab-walled seamless steel yeeb nkab nws tus kheej muaj cov yas deformation tsis zoo los yog tsis zoo quenching, qhov tshwm sim ntawm cov kab nrib pleb ntev yuav nce, tab sis qhov ua rau ncaj qha nyob ntawm qhov kev ntxhov siab ntawm cov yeeb nkab tuab-walled seamless steel yeeb nkab tom qab txias txias.
Los ntawm qhov kev xav ntawm cov txheej txheem kev sib tsoo, qhov tawg ntawm prefabricated Cheebtsam yog vim kev hloov pauv thiab nthuav dav ntawm cov micro-cracks. Longitudinal cracking ntawm tuab-walled seamless steel yeeb nkab yog cais raws li ductile cracking, thiab nws cov kab nrib pleb yog qhib hom.
Nyob rau hauv ib txwm muaj xwm txheej, lub hav zoov ntawm me me thiab nruab nrab-qhov tawg tawg nyob rau hauv cov ntaub ntawv hlau yog yam tsis muaj kev zam, tab sis raws li tib cov qauv raw khoom, seb cov kab nrib pleb yuav tshwm sim nyob ntawm qhov tshwm sim ntawm qhov kev nyuab siab tensile ntawm cov khoom prefabricated. Qhov tseeb cov nyhuv ntawm tensile kev nyuaj siab ntawm lub prefabricated lub sij hawm yog li ntawd yuav tsum tau ntxiv loaded, thiab nws muaj peev xwm kuj muaj residual nyob rau hauv-situ kev nyuaj siab nyob rau hauv nws tus kheej.
Thick-walled seamless steel yeeb nkab muaj qhov seem nyob hauv-situ kev nyuaj siab tom qab kos duab txias, tshwj xeeb tshaj yog tom qab khoob. Tus nqi siab tshaj tuaj yeem ncav cuag. Raws li cov saum toj no tensile cracking lub hauv paus ntsiab lus, nws muaj peev xwm txiav txim siab hais tias lub radial residual av kev nyuaj siab uas twb muaj lawm nyob ib sab mus rau sab nrauv ntawm cov tuab-walled seamless steel yeeb nkab muaj ib tug tseem ceeb heev tswv yim zoo ntawm lub longitudinal cracking ntawm tuab-walled seamless steel yeeb nkab.
Yog tias cov yeeb nkab tuab-walled seamless steel yeeb nkab yog qhov siab dua qhov yuav tsum tau ua kom huv, ntau dua ultrasonic siv los ntxuav nws:
Lub hauv paus ntsiab lus ntawm kev tu ultrasonic: Qhov kev hloov loj ntawm lub suab siv thaum lub ultrasonic yoj ntawm cov tuab-walled seamless steel yeeb nkab kis tau nyob rau hauv cov kua hauv lub xeev ua rau cov kua ua kom pom tseeb gas tej yam kev mob, ua rau tsheej lab ntawm cov me me cavitation npuas txhua ob. Raws li cov nyhuv muaj zog, nws tuaj yeem ua rau tawg ntau ntawm kev kub ceev, thiab nws tsis txuas ntxiv mus rau qhov hnyav, ua rau muaj kev cuam tshuam rau lub zog thiab tsis zoo siab adsorption quab yuam, uas yog txaus kom tshem tawm qhov nyuaj-rau. - tshem tawm stains.
Yog hais tias lub tuab-walled seamless steel yeeb nkab yog ntev ntev thiab nws muaj stainless hlau dab dej, koj muaj peev xwm yuav ib tug ultrasonic vibration phaj thiab nqis peev nyob rau hauv dej mus nqa tawm ultrasonic tu. Yog tias nws tsis ntev dhau lawm, koj tuaj yeem siv tus pas ntsuas ultrasonic los ntxig rau hauv lub raj xa dej los ntxuav. Lub ultrasonically detached pov tseg yog ces ntxuav tawm nrog ib tug kwj dej.
