Txoj kev dov composite yog tam sim no cov txheej txheem feem ntau siv rau kev tsim khoomstainless hlau clad phajhauv tsev thiab txawv teb chaws. Cov txheej txheem sib xyaw yog: nyob rau hauv qhov kev txiav txim ntawm lub zog siab ntawm lub dov zeb, ib tug loj yas deformation tshwm sim nyob rau hauv lub composite interface, uas ua rau cov hlau oxide txheej ntawm lub interface mus rupture thiab nthuav tawm cov dej tshiab. Nyob rau hauv cov txheej txheem hlau activated, ib qho kev sib cog lus ua ntej atomic yog tsim los ntawm ob lub hlau, thiab qhov chaw sib txuas txuas ntxiv nthuav dav thaum cov txheej txheem kho cua sov tom ntej los ua ib daim ntawv cog lus ruaj khov.
Txoj kev dov composite feem ntau muab faib ua ob pawg: kub dov thiab txias dov sib xyaw.
Kub dov compound txoj kev. Cov txheej txheem kub dov sib xyaw yog txheej txheem txheej txheem uas npaj cov pob zeb sib xyaw ua kom sov rau qee qhov kub los yog siab dua, thiab dov los ntawm cov kub txuas ntxiv dov los yog lub cub tawg coil dov zeb los tsim ib daim ntawv cog lus tiaj tus. Cov txheej txheem txheej txheem xws li kev kho deg zoo ua ntej dov, tsim nyog cov cua sov (qhov kub thiab txias, tuav lub sij hawm), thiab kev txo qis thawj zaug yog qhov tseem ceeb uas cuam tshuam rau lub zog sib txuas ntawm cov ntawv kub dov. Cov khoom lag luam tshwj xeeb tsim los ntawm cov txheej txheem kub-dov sib xyaw yog dav, qhov dav tuaj yeem ncav cuag 2800mm, cov khoom siv sib xyaw yog (1 ~ 4) hli, thiab cov thickness ntawm cov khoom siv feem ntau yog ntau tshaj 3 npaug ntawm cov hlau tsis muaj steel. . Raws li cov txheej txheem sib txawv, cov txheej txheem kub dov sib xyaw tuaj yeem muab faib ua ncaj qha kub dov, tawg vuam sib xyaw billet kub dov, brazing composite billet kub dov, thiab lub tshuab nqus tsev sib xyaw billet kub dov.
① Direct kub dov thiab cladding: Nws yog ib txoj kev ncaj qha kub dov cov ntaub ntawv clad thiab lub hauv paus cov ntaub ntawv tom qab tsim cov billet kom paub qhov metallurgical ua ke ntawm ob hlau. Txoj kev no feem ntau tuaj yeem siv cov khoom siv dov zeb uas twb muaj lawm, yog qhov yooj yim thiab siv tau yooj yim, tuaj yeem tsim cov phaj dav dav, tuaj yeem sib xyaw ua kom tuab tuab, thiab tuaj yeem paub qhov loj, kev kub ceev, thiab kev tsim khoom tas mus li. Lub ntsiab tsis zoo ntawm cov txheej txheem no yog: thaum lub pob zeb sib xyaw ua ke ncaj qha dov, muaj qee qhov huab cua ntawm qhov sib txuas, uas yooj yim rau kev tsim oxides nrog cov hlau ntsiab lus ntawm lub interface, uas cuam tshuam rau kev sib txuas zoo ntawm lub interface.
②Explosive welding kub-kuav los tiag cladding: Cov pob zeb sib xyaw ua los ntawm cov vuam tawg yog kub dov thiab clad rau ntawm lub tshuab dov, uas tuaj yeem txo qee qhov tsis xws luag los ntawm kev tawg ncaj qha. Nws coj los ua ke qhov zoo ntawm ob txoj kev npaj ib leeg, uas tuaj yeem tsis tsuas yog txhim kho cov khoom siv sib xyaw ntawm cov phaj sib xyaw, tab sis kuj tseem txhim kho lub zog ntawm kev sib txuas sib txuas. Piv nrog rau cov hlau nplaum tawg, lub phaj clad nrog lub ntsej muag zoo dua thiab cov phaj nyias nyias tuaj yeem npaj tau, thiab tib lub sijhawm, nws tsis raug raws li qhov yuav tsum tau muaj ntawm cov muaj pes tsawg leeg thiab qhov loj ntawm txoj kev ncaj qha kub dov. Tau kawg, txoj kev no tseem khaws cov teeb meem xws li cov khoom siv hluav taws xob tsawg ntawm cov txheej txheem tawg, ib puag ncig ua haujlwm tsis zoo, lub voj voog ntev ntau lawm, thiab qhov tseeb ntawm qhov tsawg;
③Brazing kub dov composite: Ntxiv cov brazing muab tub lim ntawm cov khoom siv hauv paus thiab cov khoom sib xyaw. Nyob rau ntawm qhov tsim nyog brazing kub, lub brazing muab tub lim hlau mus txog lub xeev molten, thiab ib qho kev siab yog siv rau ntawm qhov chaw ntawm cov pob zeb sib xyaw ua kom lub brazing muab tub lim hlau moist ntawm cov hlau tsis muaj steel thiab carbon hlau. Kev ntub dej, sib kis, ua kom tiav cov txheej txheem brazing, thiab paub txog qhov pib recombination ntawm ob hlau. Cov txheej txheem tom qab kub dov ua rau cov hlau atoms nyob rau hauv cov khoom siv brazing txheej tsim hlau bonds nrog Fe, Cr, Ni, thiab lwm yam atoms tom qab absorbing lub zog deformation, thiab thaum kawg, ua tiav firmness. metallurgical kev sib txuas. Kev xaiv ntawm brazing muab tub lim hlau, brazing kub, lub sij hawm brazing, thov siab, kub dov cua sov kub, txo qhov piv, thiab lwm yam txheej txheem tsis yog lub ntsiab tseem ceeb los txiav txim siab lub zog sib txuas ntawm cov khoom sib txuas hauv tag nrho cov txheej txheem sib xyaw. Piv nrog rau txoj kev tawg welding, qhov zoo tshaj plaws ntawm txoj kev brazing dov yog tias nws tuaj yeem paub qhov loj thiab batch ntau lawm, lub voj voog ntau lawm kuj luv, thiab cov khoom specification hloov pauv hloov tau. Qhov tsis zoo yog vim qhov kev txwv ntawm cov khoom siv ntau lawm thaum lub thickness ntawm clad phaj siab tshaj 30 hli thiab clad txheej tshaj 3 hli, lub interfacial shear zog ntawm cov khoom yuav tsis tau guaranteed los ntawm lub brazing kub dov txoj kev; thiab cov khoom sib xyaw ua ke uas tsim los ntawm txoj kev no yog cuam tshuam los ntawm brazing muab tub lim hlau. Cov khoom siv kho tshuab tsis zoo me ntsis, thiab nws tsis tiv taus qhov kub thiab txias.
④ Lub tshuab nqus tsev kub dov sib xyaw: Cov cua uas muaj nyob rau hauv cov khoom sib xyaw ntawm cov khoom siv hauv paus thiab cov khoom sib xyaw raug tshem tawm los ntawm lub tshuab nqus tsev ntim khoom kom nws tuaj yeem ua kom sov thiab dov hauv lub tshuab nqus tsev, kom tsis txhob muaj kev cuam tshuam ntawm oxides ntawm lub tshuab nqus tsev. composite interface, thiaj li mus cuag kev kawm siab ntawm dissimilar hlau. Kev sib xyaw zoo. Qhov no yog qhov siv ntau tshaj plaws, feem ntau tshawb nrhiav, thiab kev txhawj xeeb tshaj plaws kev sib xyaw ua ke.
Cov saum toj no yog cov lus qhia ntxaws ntxaws rau cov txheej txheem kub dov cladding hauv dov cladding txoj kev. Raws li tus kws tshaj lijhlau clad phaj Hoobkas, Baoji Taicheng Hlau Co., Ltd tsis tau tsuas yog teb cov lus nug txog cov khoom tab sis kuj muab koj nrogcustomized stainless hlau claddaim hlau, tsim nyog manufacturers tsim cov khoom tsim nyog, txais tos sab laj!
