Hauv ntau qhov xwm txheej siv. Tsis yog tsuas yog muaj qhov yuav tsum tau ua rau lub hniav rauj tsis kam hnav xwb, tab sis kuj tseem muaj qhov yuav tsum tau ua siab heev rau qhov cuam tshuam ntawm lub hniav rauj.
Yuav ua li cas thiaj ua tau ob qho tib si uas tiv taus kev hnav thiab tiv taus kev cuam tshuam? HMT lub hniav rauj tungsten carbide daws tau qhov teeb meem no zoo heev.
Raws li paub zoo, cov khoom tungsten carbide muaj qhov nyuaj siab. Ua tiav HRC72 ~ 75. Tungsten carbide rauj hniav hauv kev ua lag luam yav dhau los. Kev siv cov txheej txheem brazing lossis fiber vuam. Rauj hniav feem ntau yuav tawg thiab tawg ntawm cov hlau tawv hauv qab kev cuam tshuam siab. Muaj ntau daim rauj hniav hauv kev ua lag luam. Qhov teeb meem tsis yog tias txheej tiv taus hnav tsis yog hnav-resistant, tab sis tias txheej tiv taus hnav poob tawm hauv qab kev cuam tshuam siab.
HMT lub tshuab vuam siv tshuab fusion welding ua rau cov tungsten carbide me me sib xyaw nrog lub cev rauj, ua rau lawv sib txuas ua ke zoo. Cov tungsten carbide me me lawv tus kheej muaj kev tiv taus kev hnav thiab kev tawv. Nws zoo ib yam li muab cov cuab yeej zoo tshaj plaws rau ntawm lub cev rauj, uas txuas nrog cov ntshav thiab yuav tsis ua rau cov txheej tiv taus kev hnav poob.
HMT cov hniav rauj tungsten carbide yog cov cuab yeej ua rog uas muaj kev tiv taus kev cuam tshuam siab, tiv taus kev hnav, thiab tawv.
