Mona ke mehato e meng ea ho hlahisa lithupa tsa tungsten carbide.
1) Moralo oa Kereiti
Kereiti e entsoeng ke feme ea rona: SK10, SK30, SK35B, SK35, SK45 joalo-joalo.
Khothaletsa Kereiti e nepahetseng bakeng sa ts'ebeliso ea lithupa tsa tungsten carbide
2) RTP Ball Milling
Leloala le silang bolo le na le bokhoni ba ho etsa phofo ea boholo bofe kapa bofe ba lijo-thollo, ho kenyeletsoa phofo e ntle le e hloekileng haholo ho tsoa linthong tse kopaneng tsa phofo ea WC, phofo ea cobalt le lisebelisoa tsa doping.
Spray -Drying Process
E le ho netefatsa hore thepa e hloekile ka ho feletseng, tora ea prilling e fafatsoa ka ho omisa spray.
3) Extrusion kapa Tobetsa Tobetsa
Mekhoa e 2 e fapaneng ea ho hlahisa lithupa tsa carbide.
4)Mokhoa oa ho omisa
5)Sintering
Lehare le fumana kalafo ea mocheso ka mocheso oa likhato tse 1500 tsa Celsius ka nako ea lihora tse 15.

P: Na u khoebo ea k'hamphani kapa moetsi?
A: Re feme, ho tloha 2010.
P: Nako ea hau ea ho fana ka nako e kae?
A: Ka kakaretso ke matsatsi a 7-10 haeba thepa e le teng.kapa ke matsatsi a 15-20 haeba thepa e le sieo, ho latela bongata.
P: O fana ka mehlala?na ke mahala kapa ho feta?
A: E, re ka fana ka sampole mahala empa u se ke ua lefa litšenyehelo tsa thepa.
P: Na u fana ka litšebeletso tse tloaelehileng?
A: Ho joalo.Re tla etsa hlobo ho latela lits'oants'o tsa hau, 'me re ka romella sampole bakeng sa boleng ba tlhahlobo pele.
