◆ Carbide inserts yog tsau nyob rau hauv ib tug nickel-raws li binder theem uas muaj cam khwb cia WC hais, txhim kho cov khoom ntawm corrosion kuj;
◆ Zoo tag nrho ua ke cov hnav tsis kam ntawm carbide nrog lub toughness ntawm hlau;
◆ Cov npoo ntawm cov dej ntws tau tshwj xeeb ntxiv los txhim kho lub zog sib txuas thiab tawv, tiv thaiv nkig chipping thiab spalling ntawm txheej hardened;
◆ Cov txheej txheem kev npaj kub qis khaws cia cov khoom siv zoo heev ntawm cov hlau kho cua sov;
◆ Cov xov tsis lo;
◆ High bonding zog ntawm txheej txheej tawv thiab steel substrate;
◆ Tshwj xeeb tsim carbide blocks muaj siab hnav tsis kam thiab tawg toughness;
◆ Zoo heev cuam tshuam thiab yaig tsis kam;
◆ Muaj peev xwm thauj khoom siab;
◆ Lub neej ua haujlwm ntev dua li cov txheej txheem sintering thiab coated khoom;
◆ Reusable;
◆ Tus nqi qis dua rau kev ua haujlwm drilling;
◆ Tswj kev ua tau zoo tsis tu ncua hauv txhua qhov kev ua haujlwm hnyav;
◆ Tsawg hloov zaus thiab txo cov khoom yuav tsum tau ua;
◆ Muab koj cov cuab yeej drilling nrog kev ntseeg siab thiab kev sib tw siab.
Cov xwm txheej ua haujlwm:
Qhov chaw: Texas, USA
Khoom: Tsawg radial bearing
Kev sib hloov ceev: 400-450 r / min
Slurry concentration: 5-6%
Teeb meem:
* Ntau cov cemented carbide blocks yog tev tawm.
* Ntau qhov tawg ntawm cov cemented carbide nto.
* Cov xov yog ntes, ua rau disassembly nyuaj.
* Cov khoom siv hauv paus yog deformed, ua rau cov khoom siv tsis tau. * Microcracks ntawm cemented carbide nto.
* Tsis muaj cemented carbide thaiv tev tawm.
* Cov xov tsis yog seizing, disassembly yog du.
* Tseem rov siv tau.
Kev daws:
◆ Cov cemented carbide inserts yog tsau nyob rau hauv ib tug nickel-raws li binder theem uas muaj cam khwb cia WC hais.
◆ Qhov no zoo kawg nkaus ua ke nrog kev hnav tsis kam ntawm cemented carbide nrog lub toughness ntawm hlau.
