I-Tungsten Carbide VS HSS (1)

I-HSS (ifushane ngensimbi enesivinini esikhulu) kwakuyinto evamile yamathuluzi okusika insimbi esikhathini esidlule. Lapho kwakhiwa i-tungsten carbide, yayibhekwa njengokuthatha indawo eqondile yensimbi enesivinini esikhulu enokuqina okuhle, ukumelana nokugqokwa okuhle kakhulu, nobulukhuni obuphezulu kakhulu. I-carbide enosimende ivame ukuqhathaniswa nensimbi enesivinini esikhulu ngenxa yokusetshenziswa okufanayo nobulukhuni obuphezulu.

Ukusebenza kwe-tungsten carbide

I-Tungsten carbide iyimpushana yensimbi elingana ne-micron okunzima ukuyincibilika futhi inobulukhuni obuphezulu. I-binder yenziwe nge-cobalt, i-molybdenum, i-nickel, njll. Ifakwe emazingeni okushisa aphezulu kanye nezingcindezi eziphezulu. I-Tungsten carbide inokuqukethwe okuphezulu kwe-carbide enezinga lokushisa eliphezulu kunensimbi enesivinini esikhulu. Ine-HRC 75-80 kanye nokumelana nokugqokwa okuhle kakhulu.

Izinzuzo ze-tungsten carbide

1. Ubulukhuni obubomvu be-tungsten carbide bungafinyelela ku-800-1000°C.

2. Ijubane lokusika le-carbide liphindwe izikhathi ezingu-4 kuya kwezingu-7 kune-high-speed steel. Ukusebenza kahle kokusika kuphezulu.

3. Impilo yesevisi yesikhunta, amathuluzi okulinganisa, namathuluzi okusika enziwe nge-tungsten carbide izikhathi ezingu-20 kuya kweziyi-150 kuneyensimbi ye-alloy alloy.

4. I-Carbide ingasika impahla ngobulukhuni be-50 HRC.

Ukungalungi kwe-tungsten carbide

Inamandla okugoba aphansi, ukuqina okungekuhle, i-brittleness ephezulu, kanye nokumelana nomthelela ophansi.

Ukusebenza kwe-HSS

I-HSS iyinsimbi ephezulu ye-carbon high alloy, okuyinsimbi eyithuluzi enokuqina okuphezulu, ukumelana nokugqokwa okuphezulu, nokumelana nezinga lokushisa eliphezulu. Esimeni sokucisha, insimbi, i-chromium, i-tungsten eyingxenye, kanye nekhabhoni ensimbi enesivinini esikhulu kwakha i-carbide eqine kakhulu, ethuthukisa ukumelana nokugqokwa kwensimbi. Enye ingxenye ye-tungsten incibilika ku-matrix, ikhulise ubulukhuni bensimbi bufinyelele ku-650°C.

Izinzuzo ze-HSS

1. Ukuqina okuhle, ukuqina okuhle kakhulu, ukusika okubukhali.

2. Ikhwalithi engaguquki, evame ukusetshenziselwa ukwenza amathuluzi amancane amile.

Ukungalungi kwe-HSS

Ukuqina, impilo yesevisi kanye ne-HRC kuphansi kakhulu kune-tungsten carbide. Ekushiseni okuphezulu kuka-600 ° C noma ngaphezulu kuka-600 ° C, ubulukhuni bensimbi yesivinini esikhulu buzoncishiswa kakhulu futhi bungasetshenziswa.
