Izintambo ezingezona ezejwayelekile Ezifaka impahla

1. Izinto ezihamba nge-ferrule ne-rolling (1) i-chromium ephezulu ye-carbon esebenza ngensimbi Iningi lamanzi okuthela kanye nomzimba ohambayo linemibala ekhethekile

Ukwakhiwa kwezinto ezivuthayo nezigubha ezine-carbon ephezulu ye-carbon (i-GCr15 ne-GCr15SiMn ne-ZGCr15 ne-ZGCr15SiMn) ngobunzima kanje:

I-Ferrule ne-rollers eyenziwe nge-GCr15 ne-ZGCr15 yi-HRc61 ~ 65 no-HRc62 ~ 66

I-ferrule ne-roller eyenziwe nge-GCr15SiMn ne-ZGCr15SiMn izinto zokwakha HRc60 ~ 64, ibhola lensimbi HRc60 ~ 66

Izindleko ezenziwe nge-high-carbon steel chrome ezithwala insimbi ngokuvamile zifanelekile ukushisa amazinga okushisa -40 ° C kuya ku-130 Â ° ububanzi. Amafutha namafutha ajwayelekile

Ungahlangabezana nezidingo zemishini jikelele

I-high-carbon chromium ethwala izingxenye zensimbi ngemva kokushisa okuphezulu kuphuma emlilweni, ukulungiswa kokushisa okusebenzayo kufika kuma-degree angu-250

Ngokuqhubeka kwentuthuko ye-smelting, i-high-carbon chromium ethwala insimbi ingasebenzisa izindlela ezihlukahlukene zokufumbaza, njengokwenza ubuchwepheshe be-vacuum smelting kungathuthukisa kakhulu izinga elibonakalayo lensimbi, ikakhulukazi okwakhiwa kwe-oksijini yensimbi nokwakhiwa kwezingxube ezingekho metallic Ukunciphisa okukhulu

Ngalokhu i-chromium ephezulu ekhanda enezinsimbi zensimbi, impilo yokukhathala ingaba kabili

Ngokuya kwenani elikhulu lemininingwane yokuqhathaniswa kokuhlola kubonisa ukuthi izindlela ezahlukene zokunuka zithole i-GCr15, i-GCr15SiMn, i-ZGCr15, i-ZGCr15SiMn ethwala izinsimbi zensimbi

(2) i-carburizing enezinsimbi ezithwala izinsimbi kanye nezinye izindandatho zokukhiqiza kanye nomzimba okhulayo, ubunzima: amasongo nomzimba ohambayo we-HRC60 ~ 64, ngokuvamile ufanelekile ukushisa okusebenzayo -40 kuya ku-140 degrees Celsius, i-oil Nokugcoba ukugcoba okuvamile , ingasetshenziselwa izimo ezinkulu zokucindezela, njengama-locomotives nama-rolling kills bearings, njll, kodwa inqubo yokwelashwa yensimbi iyinkimbinkimbi kakhulu

(3) insimbi yokwenza ukushisa okungenakushisa okwenziwe nge-ring-resistant ring rolling ring, ubunzima: amasongo nama rollers akwa-HRc60 ~ 64, ibhola le-HRc61 ~ 65, uma kwenzeka kusetshenziswe ukugcoba okuvamile, okufanelekile emsebenzini Ukushisa 120 kuya ku-250 degrees Celsius, njengezindiza zezindiza, ama-turbines kagesi kanye nezinye izimo zokusebenza

(4) ukushisa okungahambisani nokushisa okunamandla okwakhiwa kwamakhilogremu okukhiqizwa kwensimbi nokugubha umzimba, ubunzima: izindandatho nomzimba wokugcoba akufanele kube ngaphansi kuka-HRc58, amanzi, i-nitric acid, ama-chemical reactants nezinye izingosi zokulimaza, ama-253 ~ 350 degrees I-Celsius

2. I-Cage material (1) Iningi lamabherethini lenziwe ngensimbi yensimbi, esetshenziswa kabanzi kakhulu yi-low-carbon steel plate stamping wave shape, ibhasikidi, isikhala esenziwe ngebhokisi, i-carbon-high chromium ensimbi. imvelo

Ama-cylinders ayenziwe nge-plate carbon engenalutho engenalutho afanelekile ekubhekaneni nezimo kanye nemvelo ye-steel bearing resistant-resistant
