Inkqubo yeMveliso kunye neNkqubo yokuFonda yeCemented carbide rod

Imivalo ye-carbide enesamente ziintonga ezingqukuva ze-carbide. I-carbide ene-cemented yi-composite material eyenziwe yi-compound ye-refractory metal (isigaba esinzima) kunye nentsimbi edibeneyo (isigaba sokudibanisa) esiveliswa ngumgubo wesinyithi.

Zimbini iindlela zokwenza iirodi ezingqukuva ze-carbide. Enye indlela kukwenza i-extrusion, eyindlela efanelekileyo yokuvelisa iintonga ezinde ezingqukuva. Olu hlobo lwe-carbide rods lunokunqunyulwa kuyo nayiphi na ubude obufunwa ngumsebenzisi ngexesha lenkqubo ye-extrusion. Nangona kunjalo, ubude bubonke abunakudlula i-350mm. Enye i-compression molding, yindlela efanelekileyo yokuvelisa ibha emfutshane. Njengoko igama lisitsho, i-carbide powder icinezelwe ibe ngumbumba.

I-alloy material yenziwe ngentsimbi ephikisayo kunye nentsimbi edibeneyo ngokusebenzisa inkqubo ye-metallurgy engumgubo. I-carbide enesamente inothotho lweempawu ezibalaseleyo ezinjengokuqina okuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina, ukuxhathisa ubushushu, kunye nokuxhathisa ukubola. ngakumbi ubunzima bayo obuphezulu kunye nokumelana nokunxiba, okuhlala kungatshintshi nakwiqondo lobushushu le-500 °C, kwaye kusenobunzima obuphezulu kwi-1000 °C. I-Carbide isetyenziswa ngokubanzi njengezixhobo zesixhobo, ezifana nezixhobo zokujika, abasiki bemilling, abacwangcisi, iidrili, izixhobo ezikruqulayo, njl. kwaye ingasetyenziselwa ukusika Ukusila okumanzi kwezixhobo ezinzima-ukusetyenzwa njengentsimbi ekwazi ukumelana nobushushu, insimbi engenasici, intsimbi ephezulu yemanganese, intsimbi yesixhobo (ilitye lokusila, ikhabhinethi yokomisa, i-Z-type mixer, igranulator)---cofa. (ngecala loxinzelelo lwehydraulic press okanye i-extruder)-- - I-Sintering (i-degreasing furnace, i-furnace edibeneyo okanye i-HIP yoxinzelelo oluphantsi lomlilo)

Izinto eziluhlaza zixutywe ngamanzi, zomisiwe, zixutywe kunye neglue emva kokulinganisa, emva koko zomiswe kwaye zinyanzeliswe uxinzelelo emva kokubunjwa okanye ukukhutshwa, kwaye i-alloy yokugqibela engenanto yenziwe ngokuchithwa kunye ne-sintering.

Ukungalungi kwemveliso ye-bar ejikelezayo ye-extrusion kukuba umjikelo wemveliso ude. Ukugqithiswa kwemivalo emincinci ejikelezayo ngaphantsi kwe-3mm, ukusika iziphelo zombini kuya kuchitha inani elithile lezinto. Ubude obude be-bar encinci ye-diameter ejikelezayo ye-carbide ene-cemented, imbi ngakumbi ukuthe tye kokungenanto. Ngokuqinisekileyo, iingxaki zokuthe tye kunye nokujikeleza zinokuphuculwa ngokugaya i-cylindrical kwinqanaba elilandelayo.

Enye i-compression molding, esetyenziselwa ukuvelisa imivalo emifutshane. Njengoko igama lisitsho, kukho isikhunta esicinezela i-carbide powder enesamente. Inzuzo yale ndlela yokwenza ibha ye-carbide ene-cemented: inokuqulunqwa ngexesha elinye kwaye inciphise inkunkuma. Yenza lula inkqubo yokusika ucingo kwaye ugcine umjikelo wezinto ezomileyo zendlela ye-extrusion. Eli xesha lifutshane lingasentla linokugcina iintsuku ezi-7-10 kubathengi.

Ukuthetha ngokuthe ngqo, ucinezelo lwe-isostatic lukwakokubumba. Ukucinezela kwe-Isostatic yeyona ndlela ifanelekileyo yokwenza imivalo emikhulu kunye nende ye-carbide. Ngokutywinwa kweepiston eziphezulu kunye nezantsi, ipompo yoxinzelelo ifaka i-liquid medium phakathi kwe-cylinder yoxinzelelo oluphezulu kunye ne-rubber egxininisiweyo, kwaye uxinzelelo luhanjiswa ngerubha edibeneyo ukwenza i-cemented carbide powder press-molded.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
