Chithandizo cha kutentha kwambiri chimagawidwa m'magulu awiri: imodzi imatha kutentha ndi kusanza kutentha, ndipo inayo ndi mankhwala kutentha kwa mankhwala. Njira yoyesera yoyeserera ndi motere:
1.
Pamtunda Kukhazikika ndi kusandutsa kutentha kutentha nthawi zambiri kumachitika ndi kuwotcha kotentha kapena lawi. Magawo apamwamba aluso amakhala owuma, kuuma kwanuko komanso kugwira ntchito mozama. Ma vackers hardness tester kapena woyeserera wolimba mtima amatha kugwiritsidwa ntchito poyesa kuwuma. Kuyesa Kusankha Kusankhidwa kumakhudzana ndi kuya kwa kuya kwa ntchito yolimba komanso kuuma kwa malo ogwirira ntchito. Pali makina atatu olimbana apa.
. Itha kugwiritsa ntchito mphamvu yoyesera ya 0,5-100kg kuti iyesetse mphamvu yolimba ngati 0,05mmm yayikulu. Kulondola kwake kumakhala kokwera ndipo kumatha kusiyanitsa makona ogwiritsira ntchito kutentha. Kusiyana pang'ono kovuta, kuphatikiza apo, kuya kwa mphamvu yolimba kumapezekanso kwa okhazikika, motero ndikofunikira kukonzekeretsa kwambiri mayunitsi omwe amathandizira kutentha kapena kugwiritsa ntchito zinthu zambiri zopangira chithandizo chotentha.
. Pali masikelo atatu a mawonekedwe owoneka bwino ofuna kusankha. Imatha kuyesa mbali zosiyanasiyana zomangira zomwe zimapangitsa kuti ogwira ntchito mozama amapitilira 0.1mm. Ngakhale kulondola kwa wowongolera wowoneka bwino kwambiri chifukwa cha zomwe zimapangitsa kuti zikhale zovuta, zimatha kukwaniritsa zofunikirazo ngati njira yodziwika bwino yoyang'anira mankhwala othandizira kutentha. .Bsides, imakhalanso ndi machitidwe ochita opaleshoni, kugwiritsa ntchito mosavuta, mtengo wotsika mtengo, muyeso wachangu, komanso kuwerenga mwachindunji mfundo zolimba. Woyendetsa modekha wolimba mtima amatha kugwiritsidwa ntchito mwachangu komanso osakhala ndi zowononga mabizinesi othamanga omwe ali ndi imodzi. Ndizofunikira kwambiri pakukonzekera zitsulo ndi makina opanga mafakitale. Pamene kutentha kwa kutentha kwa osanjikiza ndi wandiweyani. Pamene kutentha kwa kutentha kwabwino kusanjikiza ndi 0,4-0.8mm, kukula kwa HRA kungagwiritsidwe ntchito. Kuzama kwa ulusi wouma pomwe umapitilira 0,8mm, kukula kwa HRC kungagwiritsidwe ntchito. Vickers, Rockwerth ndi Surnard Rominal Makhalidwe oyendayenda mosavuta akhoza kusinthidwa mosavuta, zojambula kapena mikhalidwe yolumikizira yofunikira ndi ogwiritsa ntchito apadziko lonse lapansi. American Interm ndi Standar Standard GB / T yaperekedwa.
. Mukayeza, chidwi chiyenera kulipidwa pamtunda kumapeto ndi makulidwe athunthu ogwirira ntchito. Njira yoyesererayi ilibe phockers ndipo oyendetsa zolimbitsa thupi ndi olondola, koma ndizoyenera muyeso wamasamba mufakitale.
2. Mankhwala oteteza mankhwala
Kutentha kwa mankhwala kutenthetsani kulowera pamalopo a matomu amodzi kapena angapo akusintha kapangidwe kake, kapangidwe ndi magwiridwe antchito. Pambuyo pakuwumitsa ndi kutentha pang'ono kutentha, mawonekedwe a ntchitoyo amakhala ndi mawongoletsedwe. Ndipo kulumikizana ndi kutopa, ndipo maziko a ntchitoyo ali ndi mphamvu yayikulu komanso kuuma. Zolinga zazikulu zaukadaulo za mankhwala kutentha kutentha kwa mankhwala ndi kuya kwa mphamvu yolimba ndi kuuma kwake. Mtunda womwe kuuma kumatsikira mpaka 50hrc ndiye wogwira ntchito mozama. Kuyesa kwamphamvu kwambiri kwa kutentha kwamitundu kumafanana ndi kuyesedwa kwamphamvu kwamoto kumapangitsa kuti kutentha kunachitidwa ntchito. Ma Tracers Hardness TESers, pamtambo wolimbanakulu kwambiri kapena oyang'anira masewera olimbitsa thupi amatha kugwiritsidwa ntchito. Kupanga kolimba kuti mudziwe, kokha makulidwe a nitricker okha ndiocheperako, osaposa 0.7mm, ndiye
3.. Chithandizo cha kutentha
Ngati magawo othandizira kutentha amafunikira kuvuta kwa kutentha kwambiri, magawo owuma kwambiri amachitika pogwiritsa ntchito njira yotenthetsera, etc. Kuyeserera kwapadera kwa zojambulazo, ndipo kuyesedwa kolimba kumayenera kugwiritsa ntchito testicle yolimba kuti ayesere mtengo wa HRC. Ngati kutentha chithandizo chowuma ndi osaya, wonani kuti wolimbitsa thupi wolimba mtima akhoza kugwiritsidwa ntchito kuyesa mtengo wa HRN haminess.
