Ibicuruzwa biranga Carbide ya sima

Carbide ya sima ni ifu ya metallurgie yifu ivuye mubukomere bukabije, ifu yicyuma ivanze (nka WC, TiC, TaC, NbC nizindi karbide yubushyuhe bwo hejuru) hamwe nicyuma (Co, Mo, Ni, nibindi).Nkuko ibigize Carbide ya Cement irimo karbide nyinshi zifite aho zishonga cyane, ubukana bwinshi hamwe n’imiti myiza ihamye, ubukana, kwihanganira kwambara no kurwanya ubushyuhe bwa Carbide ya Cement iri hejuru cyane.Ubushyuhe bwo mucyumba ubukana bwa Carbide ya sima muri rusange ni 89 ~ 93HRA, bingana na 78 ~ 82HRC, kandi ubushyuhe bwo gutemwa bwemewe bureshya na 800 ℃ ~ 1000 ℃, kandi ubukana bwabwo buracyakomeza 77 ~ 85HRA ndetse no kuri 540 ℃, aribyo bihwanye nubushyuhe bwicyumba ubukana bwibyuma byihuta.

Kubwibyo, gukata imikorere ya Cemented Carbide irarenze cyane irya HSS, mugihe kimwe, umuvuduko wo kugabanya Carbide ya Cemented yemerewe kuba inshuro 4 kugeza 10 kurenza iyo HSS, kandi umuvuduko wo guca ushobora kugera kurenza 100m / min, kandi irashobora guca ubwoko bwose bwibikoresho bigoye-imashini, nkibyuma bikomeye, bidashobora gutemwa nibikoresho byo gukata HSS.Nyamara, kubera imbaraga nke zunamye (hafi 1/2 ~ 1/4 cya HSS), ubukana bwingaruka (hafi (1/8 ~ 1/30) za HSS) hamwe nubukorikori bubi, kubwubu, ibikoresho bya Carbide ya sima ni cyane ikoreshwa mugukora ibikoresho bidatinze gukata no gutunganya ibikoresho bifite imiterere yoroshye kandi nta ngaruka.Iyo karbide irimo karbide ya sima iba myinshi, ubukana buri hejuru, ariko imbaraga za flexural ni nkeya;iyo ibirimo binder biri hejuru, imbaraga za flexural ni nyinshi kandi ubukana buri hasi.ISO izaba igabanijwemo P, K na M ibyiciro bitatu bya karbide ya sima, igice cyingenzi cyibyiciro bitatu bya karbide ya sima ni WC, hamwe rero bizwi nka WC ishingiye kuri karbide.

Icyiciro cya K gihwanye nu Bushinwa bwa tungsten-cobalt ciment cbide, izina rya code YG, rigizwe ahanini na WC na Co.

Ubwoko bwa YG bwa sima ya karbide igoramye hamwe ningaruka zikomeye nibyiza, bikwiranye no gutunganya ibikoresho byoroshye, birashobora gukoreshwa mubyuma bikozwe mucyuma, ibyuma bidafite fer hamwe na alloys hamwe nibikoresho bitari ibyuma.YG ubwoko bwa karbide ya sima hamwe no kwiyongera kwa cobalt. ibirimo, ubukana bwayo buragabanuka, mugihe imbaraga zunama ziyongera, ubushobozi bwo guhangana ningaruka zo kuzamura ububi, bubereye gutunganya.Ibinyuranye, gukomera, kwambara no kurwanya ubushyuhe biriyongera, bikwiranye no kurangiza.

Icyiciro cya P gihwanye na tungsten yo mu Bushinwa, cobalt na titanium ciment ya karbide, izina rya code YT, ibiyigize usibye WC na Co, ariko kandi birimo 5% ~ 30% bya TiC, kubera ko gukomera no gushonga bya TiC birenze WC .Hamwe no kwiyongera kwa TiC, ubukana, kurwanya ubushyuhe hamwe no kwambara birwanya ibintu biragenda neza kandi byiza, mugihe imbaraga zo kugunama hamwe ningaruka zikomeye bigabanuka.

Ubwoko bwa YT bwa sima ya sima irashobora gukoreshwa mugukata byihuse ibyuma.

Icyiciro cya M gihwanye nu Bushinwa tungsten-titanium-tantalum (niobium) cobalt ciment ya karbide, yiswe YW class, yongeweho ibintu bimwe na bimwe bya TaC cyangwa NbC mubigize karbide yavuzwe haruguru kugirango hongerwe ubukana bwubushyuhe bwo hejuru, imbaraga zubushyuhe bwo hejuru hamwe no kurwanya abrasion yibikoresho bya sima ya sima.

Icyiciro cya YW kirangwa na: imikorere myiza muri rusange, uburyo bwinshi bwo gukoresha, irashobora gukoreshwa muburyo bwose bwibyuma, ibyuma, ibyuma bidafite ingese hamwe nubushyuhe bwo hejuru butunganya.

Hamwe nogukomeza kugaragara kwinshi kwa ultra-nziza nziza ya sima ya karbide hamwe nibikoresho bya karbide isize sima, imikorere yibikoresho bya karbide ya sima yaratejwe imbere cyane, kandi imbaraga za flexural, ubukana bwingaruka no kwambara karbide ya sima zateye imbere cyane, na karbide ya sima. yatangiye kandi gukoreshwa ku bwinshi mu rwego rw’ibikoresho bigoye byo gutema, nk'imyitozo, reamers, robine, imashini isya, hobs, na broach, nibindi, byose byatangiye gukorwa hamwe nibikoresho byinshi bya karbide ya sima. .

Isosiyete yacu ikora cyane cyane Carbide Rotary File, Carbide inkoni, Carbide Scraper Blade, Carbide Corrugated Slitter Knife, Carbide Woodworking Replaceable Blade nibindi bicuruzwa bya sima ya Carbide.
