Chidziwitso china chofunikira chokhudza Cemented Carbide -Matanthauzo a Zinthu Zathupi

*Kuvuta

Kuuma kwa zinthu kumatanthauzidwa ngati kuthekera kolimbana ndi zolimba Kuponderezedwa pamwamba pa chinthucho.Mainly pogwiritsa ntchito miyeso ya Rockwell ndi vickers.Monga mfundo za mayeso a Vickers ndi Rockwell ndizosiyana, chisamaliro chiyenera kutengedwa pamene mutembenuka kuchoka ku dongosolo lina kupita ku lina.

*Kulimba M'munda Wokakamiza

Mphamvu yokakamiza ndi muyeso wa maginito otsalira mu hysteresis loop pamene cobalt (Co) binder mu giredi ya simenti carbide ndi maginito kenako demagnetized.Ikhoza kugwiritsidwa ntchito poyesa momwe bungwe la alloy likuyendera .Kukula kwake kwa tirigu wa gawo la carbide ndipamwamba kwambiri kudzakhala mphamvu yokakamiza.

* Magnetic Saturation

Maginito Saturation: ndi chiŵerengero cha mphamvu maginito kuti khalidwe.Miyezo ya Magnetic Saturation pa gawo la cobalt (Co) binder mu carbide yoyimitsidwa imagwiritsidwa ntchito ndi mafakitale kuti awunike kapangidwe kake.Makhalidwe otsika a maginito a Saturation akuwonetsa kutsika kwa mpweya komanso kupezeka kwa Eta-phase carbide.machulukitsidwe apamwamba a maginito akuwonetsa kukhalapo kwa "carbon yaulere" kapena Graphite.

*Kuchulukana

Kachulukidwe (kukokera kwina) kwa chinthu ndi kuchuluka kwa voliyumu yake .Imayezedwa pogwiritsa ntchito njira yosamutsira madzi.Kuchulukirachulukira kwa carbide kumachepa motsatana ndi kuchuluka kwa cobalt pamagiredi a Wc-Co.

* Transverse Kuphulika Mphamvu

Transverse Rupture Strength (TRS) ndi kuthekera kwazinthu kukana kupindika.

*Kusanthula kwa Metallographic

Cobalt Lakes adzakhala mgwirizano pambuyo sintering , owonjezera cobalt angakhalepo m'dera lina la kapangidwe.kupanga dziwe cobalt, ngati kugwirizana gawo ndi incompletely zomatira, padzakhala ena pores otsala, maiwe a Cobalt ndi porosity akhoza kuzindikiridwa pogwiritsa ntchito microscope metallographic.

Chiyambi cha Carbide Rods Processing

1: Kudula

Kuwonjezera muyezo kutalika kwa 310 kapena 330 mm, tikhoza kupereka carbide ndodo kudula utumiki uliwonse muyezo kutalika kapena wapadera kutalika.

2: Kulekerera

Kulekerera kwabwino kwa kugaya kumatha kukhazikika mpaka h5 / h6 kulolerana, zofunikira zina zabwino zogaya zitha kukonzedwa molingana ndi zojambula zanu.

3: Chifu

Itha kukupatsirani ntchito yopangira simenti ya carbide kuti muwongolere bwino ntchito yanu
