Xikongomelo xa on-line bright heat treatment ya ti stainless steel welded pipes: xin’wana i ku herisa masalela ya ntshikelelo lowu endliwaka hi nkarhi wa cold working process ya ku rhendzeleka ka stainless steel strip eka xivumbeko xa tubular na hi nkarhi wa welding process;I endlelo ra nkoka kutiyisisa matirhelo ya ti stainless steel welded pipes kuya eka solid solution kuya eka austenite kutani hiku hatlisa yi hola ku sivela austenite kuva yinga khuluki kumbe ku cinca ka phase hinkarhi wa maendlelo yo kufumela.
Swilo Leswi Khumbaka Vutshunguri Bya Ku Hisa Hi Ku Vonakala ka On-Line
1. Nkucetelo wa mahiselo ya vutshunguri bya ku hisa
Vutshunguri bya solution i endlelo ro olovisa leri tirhaka swinene eka austenitic stainless steel.Phayiphi leyi weldiweke endzhaku ka vutshunguri bya solution yinga kuma ku tiya lokunene ka corrosion, matimba yale hansi xikan’we na plasticity yo antswa.Hi ndlela leyi ntsena yinga fikelela swilaveko swa tiphayiphi ta ti indasitiri tofana na tiphayiphi ta condenser na tiphayiphi ta tikhemikhali.
Kuya hi swilaveko swa standard swa tiphayiphi ta stainless steel eka ti condensers, mahiselo ya vutshunguri bya kuhisa ya ti austenitic stainless steel welded pipes yafanele kufika eka 1050 ~ 1150 °C.Hi nkarhi walowo, switlhela swilaveka leswaku swiphemu swale ndzeni nale handle swa tiphayiphi leti weldiweke endzhaku ka ku basisiwa hi kuhisa swiva swobasa naswona swi olova, kungari na muhlovo wa oxidation.Hikokwalaho, swilaveka kuva yiri strict hinkarhi wa ku hisa naku kufumetiwa ka tiphayiphi leti weldiweke.Ku lawula ku cinca ka mahiselo (eka miri wa furnace), phayiphi ya nsimbi yifanele kuva eka ndzhawu ya kahle yo sirhelela, naswona ndlela ya ndzhavuko yo tima mati ayi tirhisiwi ku sivela phayiphi ya nsimbi ya mahiselo yale henhla kuva yi bola na oxygen naku oxidizing ehenhla ka phayiphi .Hi ntolovelo, mahiselo ya vutshunguri bya solution ya austenitic stainless steel i 1050 ~ 1150 °C.Loko mahiselo lawa yanga fikeleriwi, xivumbeko xale ndzeni xa austenitic stainless steel axi tshamisekangi, naswona ti carbides tita khuluka, leswinga endla leswaku vuandlalo bya phayiphi ya nsimbi byinga fikeleli muhlovo wo vangama, naswona vuandlalo bya phayiphi byita vonaka byi ri bya ntima.
2. Nkucetelo wa gasi yo sirhelela
Ku hisiwa ka stainless steel welded pipe swi amukela furnace yo hisa leyi yaka emahlweni leyi nga riki na oxidation leyi nga na gasi yo sirhelela, leyi nga kumaka ndzhawu yo vangama handle ka oxidation, xisweswo yi herisa endlelo ra ndhavuko ra pickling.Tigasi to sirhelela letinga tirhisiwaka i hydrogen ya vutengi byale henhla, ammonia leyi boleke na tigasi tin’wana to sirhelela.Leswi phayiphi leyi weldiweke hi nsimbi leyi nga riki na swilo yi nga ni chromium, a swi koteki ku endla vutshunguri byo hisa lebyi vangamaka eka gasi leyi tolovelekeke yo sirhelela (yo tanihi gasi leyi bolaka ya hydrocarbon, ni swin’wana), naswona swa antswa ku yi endla eka ndhawu leyi nga riki na nchumu.Kambe eka ku hisa ka tiphayiphi leti weldiweke hi nsimbi leyi nga riki na swilo leswi nga riki na swilo leswi nga ni layini, ndhawu leyi nga ni vacuum a yi nge tirhisiwi, naswona gasi leyi nga tirhiki (yo tanihi argon) yi nga tirhisiwa.Hambi leswi ku tirhisiwa ka gasi leyi nga tirhiki tani hi gasi yo sirhelela eka ku hisa ka tiphayiphi ta austenitic stainless steel welded swina swihlawulekisi swaku ka swinga hlanganyeli eka ti khemikhali, matirhelo yo olova, ya hlayiseka naswona ya tshembheka, kambe ayi na swivumbeko swo hunguta, leswaku mbuyelo wa vutshunguri bya kuhisa a yi nge swi koti ku fikelela swilaveko swa khwalithi ya vutshunguri bya ku hisa byo vangama lebyinene.Muhlovo wa grey wa silivhere.Kuya emahlweni, ntsengo wa gasi leyinga tirhiki wule henhla naswona ayi ringanelanga eka vuhumelerisi lebyikulu.Hi ku ya hi ndzavisiso wa endlelo ro basisa hi ku hisa ni nxopaxopo ni ku kamberiwa loku phindha-phindhiweke eka khwalithi ya phayiphi leyi weldiweke hi nsimbi leyi nga riki na swilo endzhaku ka ku basisiwa hi ku hisa lokukulu, ndlela yo rhanga hi ku tirhisa gasi leyi nga tirhiki ku basisa moya eka furniture yo basisa hi ku hisa, ivi ku siviwa gasi leyi nga tirhiki leyi nga ni hayidirojeni, yi kombise leswaku ku fikeleriwa vutshunguri byo hisa lebyi vangamaka.Swilaveko swa khwalithi. Hangao Tech (Michini ya SEKO) . ku hlayisa ku hisa ku vangama annealing ku hisa ku tshungula muchini i xitirhisiwa xa muxaka wa inthanete, lexi endleriweke hi ku hlawuleka tilayini ta vuhumelerisi bya tiphayiphi leti weldiweke hi nsimbi leyi nga riki na swilo.
3. Nkucetelo wa mahiselo yo kufumela
Endzhaku ko hisa phayiphi leyi weldiweke ya stainless steel kuya eka 1050 ~ 1150 °C, phayiphi leyi weldiweke yifanele ku hatlisa ku titimela.yifanele ku hungutiwa kuya eka mahiselo lawa yanga oxidize.Hikokwalaho, mahiselo yo kufumela yana nkoka swinene, naswona ndzhawu ya mahiselo yifanele ku lawuriwa swinene.

4. Nkucetelo wa vuandlalo bya tiphayiphi leti weldiweke
Xiyimo xa vuandlalo bya stainless steel welded pipe loko yinga se nghena eka furnace xina nkucetelo lowukulu eka vutshunguri byo hisa byo vangama.Loko vuandlalo bya phayiphi leyi weldiweke byi thyakisiwe hi ndzhongho, mafurha na thyaka rin’wana eka furniture, muhlovo wa rihlaza ro vonikela ra oxide wuta humelela ehenhla ka phayiphi leyi weldiweke endzhaku ka ku lulamisiwa hi kuhisa lokukulu.Hikokwalaho, loko unga se nghena eka furniture yo basisa kuhisa, vuandlalo bya stainless steel welded pipe byifanele kuva byi basile swinene, naswona vuandlalo bya phayiphi leyi welded abyi fanelanga ku pfumeleriwa kuva na ndzhongho.Loko swilaveka, yinga omisiwa eka dryer kusungula, kutani yi cheriwa eka furniture.
5. Nkucetelo wa Ku Pfala Furnace ya Vutshunguri byo Hisisa
Furnace yo basisa kuhisa yifanele ku pfariwa naswona yi hambanisiwa na moya wale handle.Ngopfu ngopfu ndzhawu leyi phayiphi leyi weldiweke yi nghenaka eka miri wa furniture xikan’we na ndzhawu leyi phayiphi leyi weldiweke yi huma eka miri wa furniture, ring yo pfalela eka tindzhawu leti ya olova swinene ku ambala, hikokwalaho yifanele ku kamberiwa nkarhi na nkarhi naswona yi cinciwa hi nkarhi.Leswaku ku sivela micro-leakage, gasi yo sirhelela eka furnace yifanele ku hlayisa ntshikelelo wokarhi wa kahle.Loko kuri gasi leyi sirhelelaka hayidirojeni, hi ntolovelo yi laveka kuva yikulu kutlula ntshikelelo wa xibakabaka lowu tolovelekeke.
6. Nkucetelo wa swilo swin’wana eka vutshunguri bya ku hisa loku vangamaka
Hi nkarhi wa maendlelo yo tirha, swa laveka ku tiyisisa leswaku welding yi ya emahlweni naswona yi tshamisekile.Loko kuri na makhumbi kumbe swirhabyani eka phayiphi leyi weldiweke, ntirho wa furniture yo basisa kuhisa wufanele ku yimisiwa, handle ka sweswo phayiphi leyi weldiweke yinga pfurha eka furniture.Ku engetela kwalano, mbuyelo wa welding awuri kahle, naswona moya kumbe ndzhongho lowu fafazeriweke kusuka eka hole ya welding swita onha xibakabaka xo sirhelela eka furnace naswona swita khumba mbuyelo wo vangama wa vutshunguri bya kuhisa.
