induction Ukufudumeza uxinzelelo kuxinzelelo

Induction Ukufudumeza uxinzelelo Kwisinyithi esenziwe kubanda, senziwe, senziwe ngomatshini, sadityaniswa, okanye sanqunyulwa, kungafuneka ukuba kwenziwe umsebenzi wokunciphisa uxinzelelo ukunciphisa uxinzelelo olwenziwe ngexesha lenkqubo yokuqamba.

Induction Ukufudumeza uxinzelelo Sisebenza kuzo zombini ii-alloys ezine-ayoni kunye nezinga-ayoni kwaye senzelwe ukususa uxinzelelo lwentsalela yangaphakathi eveliswa ziinkqubo zangaphambili zokuvelisa ezinje ngomatshini, ukuqengqeleka okubandayo kunye nokudibanisa iwelding. Ngaphandle kwayo, ukwenziwa okulandelayo kunokubangela ukuphazamiseka okungamkelekanga kunye / okanye izinto ezinokubakho kwiingxaki zenkonzo ezinje ngokuqhekeka koxinzelelo. T Unyango alujoliswanga ekuveliseni utshintsho olubonakalayo kulwakhiwo lwezixhobo okanye iipropathi zoomatshini, kwaye ke ngesiqhelo kuthintelwe kubushushu obuphantsi.

Kwisinyithi esenziwe kubanda, senziwe, senziwe ngomatshini, sadityaniswa, okanye sanqunyulwa, kungafuneka ukuba kwenziwe umsebenzi wokunciphisa uxinzelelo ukunciphisa uxinzelelo olwenziwe ngexesha lenkqubo yokuqamba.

Uxinzelelo kwisinyithi njengesiphumo sokuqamba kungabangela utshintsho lobungakanani obungafunekiyo, ukugqwetha, ukusilela ngaphambi kwexesha okanye ukubola koxinzelelo lwenxalenye xa kukhutshwa uxinzelelo. Amacandelo aneemfuno eziqinileyo zokufuna uxinzelelo ngaphambi kokuba kwenziwe eminye imisebenzi. Amacandelo ane-welding angenziwa ngaphandle koxinzelelo kunye nomsebenzi wokufudumeza uxinzelelo.

Uxinzelelo loxinzelelo inokwenziwa kwigumbi lomoya elilawulwayo okanye vacuum ukunciphisa igcwala.

Iicarbon steels kunye nealloy steels zinokunikwa ngeendlela ezimbini zokuphelisa uxinzelelo:
Unyango ngo-1-150 ° C luthomalalisa uxinzelelo oluphezulu emva kokuqina ngaphandle kokunciphisa kakhulu ubunzima (umz. Izinto ezilukhuni, iibheringi, njl.
2. Unyango ngo-600-680 ° C (umz. Emva kokuwelda, ukutyabeka njalo njalo) kubonelela ngoxinzelelo olupheleleyo.

Iialloys ezingenazintsimbi luxinzelelo oluhlaziyiweyo kumaqondo ahlukeneyo amaqondo obushushu ahambelana nohlobo lwengxubevange kunye nemeko. Iialloys eziqiniswe bubudala zithintelwe kuxinzelelo lokukhulula amaqondo obushushu angaphantsi kobushushu obugugayo.
I-Austenitic steels ezingenazintsimbi zixinzelelekile zingaphantsi kwe-480 ° C okanye ngaphezulu kwe-900 ° C, amaqondo obushushu phakathi kokunciphisa ukumelana nokubola kumabakala angaqinisekanga okanye aphantsi kwekhabhoni. Unyango olungaphezulu kwe-900 ° C zihlala zizisombululo ezizeleyo.

Ukwenza ulungelelwaniso kusetyenziselwe ezinye, kodwa ayizizo zonke, iinyithi zobunjineli, ukumisa okuqhelekileyo kunokuthambisa, kuqinise okanye kuxinzelelo kunciphise into, kuxhomekeke kwimeko yayo yokuqala. Injongo yonyango kukuchasana nefuthe leenkqubo zangaphambili, njengokuphosa, ukubumba okanye ukuqengqa, ngokucokisa ulwakhiwo olungalinganiyo lube lolunye olonyusa ukungabinakho ukusebenza / ukwenzeka okanye, kwiifom ezithile zeemveliso, luhlangabezana neemfuno zokugqibela zepropathi.

Injongo ephambili kukumisa isinyithi ukuze, emva kokubumba okulandelayo, icandelo liphendule ngokwanelisayo ekusebenzeni okomeleleyo (umz. Ukunceda uzinzo lobukhulu). Ukulungelelanisa kubandakanya ukufudumeza isinyithi esifanelekileyo kubushushu obuqhelekileyo kuluhlu lwe-830-950 ° C (phezulu okanye ngaphezulu kobushushu obomeleleyo bezinyithi ezomeleleyo, okanye ngaphezulu kobushushu be-carburising bee-carburising steels) emva koko zipholise emoyeni. Ukufudumeza kuhlala kuqhutywa emoyeni, ke ukwenziwa koomatshini okulandelayo okanye ukugqitywa komphezulu kuyafuneka ukuze kususwe isikali okanye umaleko otyhafileyo.

Izinyithi ezomisa umoya (umz. Ezinye izitishi zegiya elibizwa ngokuba yi-automotive gear) zihlala “ziqhutywa ngumsindo” (zihlonyelwe ngokwemiqathango) emva kokuqhela ukuthomalalisa ulwakhiwo kunye / okanye ukukhuthaza ukusetyenziswa kwamandla. Ukucaciswa kweenqwelomoya ezininzi kukwafuna olu dibaniso lonyango. Iintsimbi ezingaqhelekanga ngesiqhelo zezo zinokuba lukhuni kakhulu ngexesha lokupholisa umoya (umzekelo, izixhobo ezininzi zentsimbi), okanye ezo zingafumani nzuzo kulwakhiwo okanye zivelise izakhiwo ezingafanelekanga okanye iipropathi zoomatshini (umz. Iintsimbi ezingenasici).

Induction ukutshisa umatshini wePWHT Isetyenziswa ngokubanzi kumbhobho / ityhubhu ye-weld peheat kunye ne-pwht, uxinzelelo oluphindaphindiweyo njalo njalo.

I-Welding yenye yeenkqubo ezibaluleke kakhulu ekwenziweni kweenqanawa zoxinzelelo ezifana nebhoyila yesityalo samandla ashushu. Iqondo lobushushu ledama elinyibilikisiweyo le-weld ngexesha lenkqubo likuluhlu lwe-2000 deg C. Ukonyuka kobushushu kuyakhawuleza kwaye kwangoko. Xa esi siqwengana sedama linyibilikileyo lipholile isinciphiso sibangela uxinzelelo lwe-thermal oluvaleleke ngaphakathi kwisinyithi. Oku kunokutshintsha ubume bentsimbi.

I-PWHT ishenxisa ezi ziphumo ngokushushubeza, ukufunxa, nokupholisa indawo ye-weld ngendlela elawulwayo ukuya kumaqondo obushushu angaphantsi kwenqaku lokuqala lenguqu, inika ubume be-macro ixesha elaneleyo lokuhlengahlengisa imeko yentsusa nokususa uxinzelelo olushiyekileyo.

I-PWHT ibandakanya ukufudumeza isinyithi emva kwenkqubo ye-welding ngendlela elawulwayo ukuya kwiqondo lobushushu elingaphantsi kwenqaku lokuqala lenguqu, ukufunxa kobo bushushu ixesha elide ngokwaneleyo, kunye nokupholisa kumazinga alawulwayo.

Ukutshisa ukutshisa yenye yeendlela ezifumana ukuthandwa nangona iindleko ziphezulu. Le yinkqubo enobushushu ngakumbi kwiwelder. Ngokungafaniyo ukufudumeza ukuxhathisa kuphela kumbhobho oshushu. Iigradients zobushushu ziyafana kubukhulu.

Amandla okufudumeza avela kwi-10KW ~ 120KW

Umzekelo: 10KW, 20KW, 40KW, 60KW, 80KW, 120KW njalo njalo.
