Musiyano pakati peTungsten Carbide neHSS Kucheka Zvishandiso

Mukuwedzera kune tungsten carbide zvinhu, maturusi ekucheka anogona zvakare kugadzirwa neakakwira-kumhanya simbi zvinhu. Nekudaro, nekuda kweakasiyana maumbirwo emakemikari uye nzira dzekugadzira tungsten carbide uye yakakwirira-yesimbi simbi, mhando yezvigadzirwa zvekucheka zvakagadzirirwa zvakasiyanawo.

1. Chemical properties

Simbi inomhanya-mhanya, inozivikanwawo sesimbi yekumhanya-mhanya kana simbi yekumberi, inowanzonzi HSS, iyo huru yemakemikari zvikamu kabhoni, silicon, manganese, phosphorus, sarufa, chromium, molybdenum, nickel, uye tungsten. Kubatsira kwekuwedzera tungsten uye chromium kumberi simbi ndeyekusimudzira kupfava kwekupokana kwechigadzirwa kana kuchipisa, nekudaro ichiwedzera kukurumidza kwayo yekucheka.

Tungsten carbide, inozivikanwawo secemented carbide, ndeye alloy zvinhu zvakavakirwa pane refractory simbi yakaoma komisheni uye simbi sebhainda. Makomisheni akaomarara akajairika ndeye tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, nezvimwewo, uye zvakajairika zvinosungirirwa icobalt, nickel, iron, titanium, nezvimwe.

2. Zvinhu zvemuviri

Simba rekushanduka-shanduka-chinangwa chakakwira-kumhanya simbi ndeye 3.0-3.4 GPa, iko kuomarara kuri 0.18-0.32 MJ/m2, uye kuomarara kuri 62-65 HRC (kana tembiricha yakwira kusvika 600 ° C kuti kuoma kuchave. 48.5 HRC). Zvinogona kuonekwa kuti high-speed simbi ine hunhu hwesimba rakanaka, kunaka kupfeka kuramba, kushivirira kwepakati nekupisa, uye kuderera kwe thermoplasticity. Ehe, iwo chaiwo maratidziro ekuita e-high-speed simbi ane hukama nemakemikari ayo uye raw material ratio.

Simba rekumanikidza reinowanzo shandiswa tungsten carbide i6000 MPa uye kuoma kuri 69~81 HRC. Kana tembiricha yakwira kusvika 900 ~ 1000 ℃, kuomarara kuchiri kuchengetedzwa kunosvika makumi matanhatu HRC. Mukuwedzera, ine simba rakanaka, kuoma, kupfeka kuramba, kupisa kwekushisa, uye kusagadzikana kwemarara. Nekudaro, iwo chaiwo maratidziro ekuita ecemented carbide ane hukama zvakanyanya neayo makemikari kuumbwa uye raw material ratio.

3. Nzira yekugadzira

Maitiro ekugadzirwa kwesimbi inomhanya-mhanya kazhinji: kunyungudutswa kwechoto, kukwenenzverwa kwechoto, vacuum degassing, electro slag remelting, muchina unokurumidza kuumba, nyundo yekuumba, kunyatsovhara muchina, kupisa kunoputika muzvigadzirwa, ndiro element, uye kudhirowa. mune zvigadzirwa.

Maitiro ekugadzira tungsten carbide anowanzo: kusanganisa, kunyorova, kuomesa, kudzvanya, uye sintering.

4. Mashandisirwo

Simbi inomhanya zvakanyanya ndiyo inonyanya kushandiswa kugadzira maturusi ekucheka (akadai sezvibhorani, matepi, nemasaha) nematurusi chaiwo (senge hobho, magiya ekuumba, uye mabhuroche).

Kunze kwekucheka maturusi ayo tungsten carbide inoshandiswawo kugadzira migodhi, kuyera, kuumba, kusapfeka-kusapfeka, kutonhora kwakanyanya, nezvimwe zvishandiso zvakare.

Kunyanya pasi pemamiriro akafanana, kumhanya kwekucheka kwetungsten carbide midziyo ndeye 4 kusvika ku7 nguva yakakwirira kupfuura iyo yesimbi yepamusoro-soro, uye hupenyu huri 5 kusvika ku80 nguva yakakwirira.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
