Chidule cha Chithandizo cha Kutentha

Kuchiza kutentha ndi njira yomwe imagwiritsa ntchito kutentha koyendetsedwa ndi kuziziritsa kusintha mawonekedwe a kristalo azitsulo ndi zitsulo zazitsulo (monga zitsulo ndi aluminiyamu).M’kupita kwa nthaŵi, njira zambiri zosiyanasiyana zapangidwa.Kutengera zakuthupi ndi chithandizo, chithandizo cha kutentha chingapereke mapindu ambiri,kuphatikiza kuuma kowonjezereka, kukana kutentha kwabwino, kukulitsa ductility, ndi mphamvu zambiri zakuthupi.

Ngakhale kuti anthu ambiri sadziwa kuti chithandizo cha kutentha ndi chiyani, ndi gawo lofunika kwambiri pakupanga.Ikhoza kugwiritsidwa ntchito pazigawo zosiyanasiyana za kupanga kusintha zinthu zina zachitsulo kapena aloyi.Makampani ena odziwika omwe chithandizo cha kutentha chimakhala ndi gawo lofunikira ndikuphatikizapondege, magalimoto, hardware(monga macheka ndi nkhwangwa),makompyuta, ndege, asilikali, ndi makampani amafuta ndi gasi.

Kodi Chithandizo cha Kutentha Kumagwira Ntchito Motani?

Tchati cha Kuthamanga kwa Kutentha

Zinanenedwa kale kuti chithandizo cha kutentha kwenikweni ndicho kusintha kwa thupi lachitsulo mwa kutenthedwa kapena kuziziritsa molamulidwa, ndipo kwenikweni chithandizo cha kutentha chimagwira ntchito pa mfundo yosavuta imeneyo.Ngakhale pali mitundu yambiri ya chithandizo cha kutentha, amatsatira njira yofanana.Mwachidule,kutentha kutentha kumagwira ntchito potenthetsa chitsulo, kuchigwira pa kutentha kumeneko, ndiyeno kuziziritsanso.Chifukwa chomwe katundu wazitsulo amasintha panthawiyi ndikuti kutentha kwakukulu kumasintha microstructure yachitsulo, yomwe imakhala ndi gawo lofunika kwambiri pazitsulo zamakina.

Kutalika kwa nthawi yomwe zitsulo zimatenthedwa zimatchedwa "nthawi yopuma“.Kutalika kwa nthawi yothira kumagwira ntchito yofunika kwambiri pazitsulo zachitsulo, chifukwa microstructure yachitsulo yonyowa kwa nthawi yayitali imasintha mosiyana ndi chitsulo chonyowa kwa nthawi yochepa.Kumbali ina, kuzizira pambuyo pa nthawi yonyowa kumakhudzanso zotsatira zachitsulo.Chitsulocho chikhoza kuzirala mofulumira, chomwe chimatchedwa quenching, kapena chikhoza kukhazikika pang'onopang'ono mu ng'anjo kuti chitsimikizidwe kuti zotsatira zomwe zikufunidwa zikukwaniritsidwa.Kuphatikizika kwa kutentha konyowa, nthawi yonyowa, kutentha kozizira ndi nthawi yozizira zonse zimathandizira kupanga zinthu zomwe zimafunikira muzitsulo kapena aloyi.

Mwachidule, njira yochizira kutentha imafuna njira zitatu zofunika,kutenthetsa, kunyowetsa, ndi kuziziritsa.

Magawo a Kutentha

The microstructure wa aloyi amasintha pa kutentha kutentha ndondomeko.Kutentha kumatsatira mbiri yamafuta enaake.Panthawiyi chitsulo chikhoza kukhala m'madera atatu osiyana, osakaniza makina, njira yolimba, kapena kuphatikiza zonse ziwiri.Dziko lirilonse limabweretsa makhalidwe osiyanasiyana ndipo boma likhoza kusinthidwa ndi kutentha molingana ndi chithunzi cha gawo.

The Soaking Stage

Cholinga cha gawo lonyowa ndikusunga chitsulo pa kutentha koyenera mpaka mkati mwakufuna mkati.Kutalika kumatengera zofunikira.Mwachitsanzo, mtundu wa zinthu ndi kukula kwa gawolo, pamene kukula kwa gawo kuli kwakukulu, nthawi yochuluka imafunika.Pakatikati pa zigawo zambiri zimatenga nthawi yayitali kuti zifike kutentha komwe kumafunikira.

Gawo Loziziritsa

Panthawi yozizira, muyenera kuziziritsa zitsulo kuti zibwerere kutentha, koma pali njira zosiyanasiyana zochitira izi malinga ndi mtundu wachitsulo.Zingafune sing'anga yozizira, gasi, madzi, olimba kapena kuphatikiza kwa izo.Mlingo wa kuziziritsa kumadalira chitsulo chokha ndi sing'anga yozizira.Choncho, kusankha komwe mumapanga pozizira ndi chinthu chofunika kwambiri pa ntchito yofunidwa yachitsulo.

Njira Zochizira Kutentha Kwambiri ndi Zopindulitsa

Pali njira zambiri zothandizira kutentha zomwe mungasankhe.Aliyense wa iwo ali ndi makhalidwe enaake.Njira zodziwika bwino zochizira kutentha ndi:

Kuwumitsa

Chimodzi mwazofala kwambiri zochizira kutentha,izi zimawonjezera kuuma kwa chitsulo kapena aloyi ndikupangitsa kuti ductile ikhale yochepa.Nthawi zambiri, pakuumitsa kwapamtunda popanda kuumitsa kotsatira, komwe kumadziwikanso kuti nitriding, ndiko kufalikira kwa nayitrogeni pamwamba pazitsulo zapadera za alloy, zomwe zimapangitsa kuti pakhale malo olimba komanso ofewa popanda chithandizo china.

Kutentha

Kutentha ndi njira yochepetsera kuuma kwambiri komanso kuphulika komwe kumachitika panthawi yowumitsa.Zovuta zamkati zimatsitsimutsidwanso.Nthawi zambiri, kutenthetsa ndi gawo lomaliza la kuuma.Ndi njira yochizira kutentha yomwe imathandiza kuti zitsulo zikhale bwino.Ma aloyi opangidwa ndi chitsulo nthawi zambiri amakhala olimba, koma nthawi zambiri amakhala osasunthika kuti agwiritse ntchito.Kutentha kumathandiza kusintha kuuma, brittleness ndi ductility zitsulo.Izi ndikupangitsa kuti ntchitoyi ikhale yosavuta.

Annealing

Annealing amafewetsa chitsulo.Zimapangitsa chitsulo kukhala choyenera kugwira ntchito ndi kuzizira.Imawonjezeranso machinability, ductility ndi kulimba kwa metal.M'kati mwa annealing, zitsulo zimatenthedwa pamwamba pa kutentha kwapamwamba kwambiri ndikuzizizira pang'onopang'ono.

Normalizing

Normalizing ndi mtundu wina wa annealing.Amazolowerakuchepetsa nkhawa zamkati zomwe zimayambitsidwa ndi njira monga kuwotcherera, kuponyera kapena kuzimitsa. Chitsulo chokhazikika chimakhala cholimba komanso champhamvu kuposa chitsulo chosakanizika.Pochita izi, zitsulo zimatenthedwa kutentha kwa 40 ° C kuposa kutentha kwake kwapamwamba kwambiri.Pankhaniyi, zitsulo zimatenthedwa kufika 200 ° F, pamwamba pa kutentha kwa annealing.Katswiriyo amasunga zitsulo pa kutentha kwakukulu mpaka kusintha kuchitike.Njira yochizira kutenthayi imafuna kuziziritsa kwa mpweya mutatha kutentha.

Monga mtsogoleri pa chithandizo cha kutentha, ProLean Hub imapereka ntchito zosiyanasiyana zochizira kutentha.Malo athu amasamalira zigawo zamitundu yonse molingana ndi miyezo yoyenera ndipo amapereka zotsatira zodalirika, zobwerezabwereza.Ntchito zathu zochizira kutentha zimayendetsedwa ndi akatswiri ena odziwa bwino ntchito komanso odziwa bwino ntchito zamakampani, omwe ali ndi chidziwitso komanso ukadaulo wopereka chithandizo chofunikira komanso kumvetsetsa kowona kwa makasitomala athu.Mutha kuyendera wathuTsamba Lothandizira Kutenthakuti mudziwe zambiri, kapena mungathelankhulani mwachindunji ndi m'modzi mwa mainjiniya athu.
