Ukukhishwa Kwesivinini

Ukukhishwa Kwesivinini kuyinqubo yokushisa elandelwa ukupholisa ngokuvamile ngokushesha ukuze kwandiswe ubulukhuni namandla omshini wensimbi.

Kuze kube manje, insimbi ishiselwa ezingeni lokushisa elingaphezudlwana kwesilinganiso esiphezulu (phakathi kuka-850-900ºC) bese ipholiswa ngokushesha noma kancane (kuye ngezici zensimbi) endaweni efana nowoyela, umoya, amanzi, amanzi. kuhlanganiswe nama-polymers ancibilikayo, njll.

Kunezindlela ezahlukene zokushisisa ezifana nohhavini kagesi, umpheki wegesi, usawoti, ilangabi, induction, njll.

Izinsimbi ezivame ukusetshenziswa ekuqiniseni induction ziqukethe kusuka ku-0.3% kuya ku-0.7% carbon (ama-hypoeutectic steels).

Ukushisa ukushisa izinzuzo:

• Iphatha ingxenye ethile yesiqephu (iphrofayili eqinile)
• Ukulawula Imvamisa kanye nezikhathi zokushisisa
• Ukulawula ukupholisa
• Ukonga Amandla
• Akukho ukuthintana ngokomzimba
• Lawula futhi ubeke ukushisa
• Ingahlanganiswa emigqeni yokukhiqiza
• Khulisa ukusebenza futhi konga isikhala

Ukuqina kwe-induction kungenziwa ngezindlela ezimbili ezihlukene:

• Okumile: kuhlanganisa ukusetha ingxenye phambi kwe-inductor nokwenza umsebenzi ngaphandle kokuhambisa ingxenye noma i-inductor. Lolu hlobo lokusebenza lushesha kakhulu, ludinga kuphela ama-mechanics alula futhi luvumela ukwenziwa kwasendaweni okunembe kakhulu kwendawo ephathwayo, ngisho nezingxenye ezinejometri eyinkimbinkimbi.

• Okuqhubekayo (ngokuskena): kuhlanganisa ukweqa ingxenye ngokusebenza okuqhubekayo, ukuhambisa ingxenye noma i-inductor. Lolu hlobo lokusebenza lusho ukuthi izingxenye ezinezindawo ezinkulu nosayizi abakhulu zingelashwa.

Ohlotsheni olufanayo lwengxenye yokwelashwa kokuskena kudinga amandla amancane anesikhathi eside sokwelashwa uma kuqhathaniswa nokwelashwa okumile.

I-Induction Tempering

I-Induction Tempering kuyinkqubo ekwazi ukunciphisa ubulukhuni, amandla futhi ikhulise ukuqina kwezinsimbi eziqinile, kuyilapho isusa ukungezwani okudalwe ethempelini, ishiya insimbi ngobulukhuni obudingekayo.

Isistimu yokushisa evamile iqukethe ukushisisa izingxenye emazingeni okushisa aphansi kakhulu (kusuka ku-150ºC kuya ku-500°C, njalo ngaphansi komugqaAC1) okwesikhashana bese uziyeka ziphole kancane.

Izinzuzo zokushisa kokungeniswa:

• Izikhathi ezimfushane kunqubo
• Ukulawula ukushisa
• Ukuhlanganiswa emigqeni yokukhiqiza
• Ukonga Amandla
• Ukutholakala ngokushesha kwezingxenye
• Ilondoloza indawo yaphansi
• Izimo zemvelo ezithuthukisiwe

Inqubo yokuqina nokushisa iwukwelashwa kwezingxenye ezihlukahlukene emikhakheni eminingi yezimboni.
