Indlela yokuphepha iiNdaba kwiiMveliso ze-Cemented Carbide Extrusion

Kuqhelekile ukusebenzisa iteknoloji ye-powder extrusion ukuvelisa iimveliso ze-tungsten carbide kunye neentonga ze-carbide ekuveliseni iimveliso ze-tungsten carbide. I-samente ye-carbide extrusion yinto enokwenzeka yokwenza itekhnoloji kwimveliso ye-carbide yanamhlanje. Nangona kunjalo, iimveliso ze-extrusion zinokubonakala ziqhekekile ngexesha lenkqubo yokuvelisa. Eli nqaku liza kuthetha ngendlela yokuphepha iintanda kwi-cemented carbide extrusion molding.

Indlela ye-extrusion inokwahluka kwayo xa kuthelekiswa neteknoloji yokubumba yendabuko kunye neteknoloji yokucinezela isotactic. Inkqubo yemveliso yesamente yokubumba i-carbide extrusion ibandakanya la manyathelo alandelayo: ukudibanisa umgubo kunye ne-ejenti yokubumba → ukubunjwa kwe-extrusion → ukulungiswa kokutshisa → i-vacuum sintering → ukupakishwa kwemveliso egqityiweyo → imveliso egqityiweyo. Inkqubo yemveliso ibonakala ilula ngokwenene, kodwa kulula kakhulu ukuvelisa iimveliso zenkunkuma eziqhekekileyo ukuba kukho ukungakhathali ngexesha lemveliso.

Kukho izizathu ezininzi zokuqhekeka, njengemimiselo yesakhiwo esingenangqiqo se-extrusion die, i-ejenti yokubumba enganelisiyo, ukusebenza kakubi kokubumba umxube, inkqubo engafanelekanga yokukhupha, inkqubo ye-sintering yangaphambili, kunye nenkqubo ye-sintering, njl.

Isiphumo se-arhente yokubumba i-extrusion kwiintanda:

Ukuba usebenzisa iparafini okanye i-arhente yokubumba yohlobo lwe-A phantsi kweemeko ezifanayo zokuxovula, ukongeza kakhulu okanye kungonelanga i-arhente yokubumba iya kubangela zombini iintanda kwiimveliso, Ngokuqhelekileyo, izinga lokuqhekeka kweparafini liphezulu kunolo lwe-arhente yokubumba yohlobo lwe-A. Ngoko ke, kwinkqubo yokuveliswa kweemveliso ze-carbide extrusion, ukukhethwa kwe-arhente yokwenza kunye nobungakanani bokulawulwa kwee-arhente zokubumba kubaluleke kakhulu.

Isiphumo sesantya sokufudumeza sangaphambili:

Ukuqhekeka kwemveliso ye-semi-finished ihambelana nomlinganiselo wokufudumeza. Ngokukhawuleza kwezinga lokufudumeza, ukunyuka kwanda. Ukunciphisa iintanda kwimveliso, eyona ndlela ilungileyo kukusebenzisa amaxabiso ahlukeneyo okufudumeza kwangaphambi kwe-sintering kubungakanani obuhlukeneyo beemveliso ezigqityiweyo.

Ukudibanisa, ukwenzela ukunciphisa i-phenomenon yokuqhekeka kweemveliso ze-carbide ze-cemented extrusion, kubalulekile ukuba uqaphele la manqaku alandelayo. Inkqubo yokuveliswa kweemveliso ze-carbide extrusion kufuneka ilawulwe ngokungqongqo. I-agent eyenza uhlobo lwe-A lunempembelelo engcono ekuthinteleni iintanda kwiimveliso. Ukongeza, isantya sokufudumeza sangaphambi kwe-sintering yeemveliso ezikhutshiweyo zihambelana ngokuthe ngqo kwisehlo semveliso yenkunkuma eqhekekileyo. Ukusebenzisa isantya sokufudumeza esicothayo kwiimveliso ezinkulu kunye nokusebenzisa isantya sokufudumeza ngokukhawuleza kwiimveliso ezincinci zikwayindlela esebenzayo yokuphepha inkunkuma ye-carbide extrusion crack.

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