Cemented Carbide ihupfu simbi yakagadzirwa nesimbi yakaomeswa kubva mukuoma kwepamusoro, refractory simbi musanganiswa upfu (seWC, TiC, TaC, NbC uye mamwe epamusoro-tembiricha carbides) uye simbi binder (Co, Mo, Ni, nezvimwewo).Sezvo kuumbwa kweCemented Carbide kuine huwandu hukuru hwema carbides ane yakakwira kunyungudika, kuomarara kwepamusoro uye kugadzikana kwakanaka kwemakemikari, kuomarara, kupfeka kuramba uye kupisa kupisa kweCemented Carbide kwakakwira zvakanyanya.Kuoma kwekushisa kwekamuri yeCemented Carbide inowanzoita 89 ~ 93HRA, iyo yakaenzana ne78 ~ 82HRC, uye tembiricha yekucheka inobvumidzwa yakakwira kusvika 800 ℃ ~ 1000 ℃, uye kuoma kwayo kuchiri 77 ~ 85HRA kunyangwe pa540 ℃, iyo yakaenzana nekuoma kwekushisa kwekamuri kwesimbi yakakwirira-kumhanya.
Naizvozvo, kuita kwekucheka kweCemented Carbide kwakakwira zvakanyanya kupfuura iyo yeHSS, pasi pekusimba kwakafanana, kumhanya kwekucheka kweCemented Carbide kunobvumidzwa kuva 4 nguva kusvika 10 yakakwira kupfuura iyo yeHSS, uye kumhanya kwekucheka kunogona kusvika kupfuura. 100m/min, uye inogona kucheka marudzi ese emhando dzakaoma-kune-muchina, senge simbi yakaoma, isingagoni kutemwa neHSS yekucheka maturusi.Nekudaro, nekuda kwesimba rayo rekukotama rakaderera (rinenge 1/2 ~ 1/4 yeHSS), kuoma kwesimba (inenge (1/8 ~ 1/30) yeHSS) uye kusashanda zvakanaka, saka, parizvino, Cemented Carbide zvinhu zviri. inonyanya kushandiswa mukugadzirwa kweasina-inopindirana yekucheka uye machining maturusi ane nyore kumucheto chimiro uye pasina kukanganisa.Kana iyo carbide yemukati mune simende carbide yakakwira, kuomarara kwakakwira, asi iyo flexural simba yakaderera;kana iyo binder yemukati yakakwira, iyo flexural simba yakakwira uye kuoma kwakaderera.ISO ichakamurwa kuita P, K uye M mapoka matatu ecemented carbide, chikamu chikuru chezvikamu zvitatu zvecemented carbide iWC, saka pamwe chete inozivikanwa seWC-based cemented carbide.
K kirasi yakaenzana neChina tungsten-cobalt simende carbide, kodhi zita YG, inonyanya kuumbwa neWC uye Co.
YG mhando ye simende carbide kupeta simba uye kusimba kwekuita zviri nani, inokodzera brittle zvinhu kugadzirisa, inogona kushandiswa simbi yakakandwa, isiri-ferrous simbi uye alloys ayo uye isiri-metallic materials processing.YG rudzi rwesimende carbide nekuwedzera kwecobalt zvemukati, kuomarara kwayo kunodzikira, uku simba rekukotama richiwedzera, kugona kutsungirira kukanganisa kwekusimudzira kweiyo roughing, inokodzera hutsinye machining.Pane zvinopesana, kuoma, kupfeka kusagadzikana uye kupisa kupisa kunowedzera, kwakakodzera kupedzisa.
P kirasi yakaenzana neChina tungsten, cobalt uye titanium simende carbide, kodhi zita YT, kuumbwa kwayo kuwedzera kune WC uye Co, asi zvakare ine 5% ~ 30% yeTiC, nekuti kuoma uye kunyungudika kweTiC kwakakwira kupfuura WC. , saka kuoma, kupfeka kuramba uye kupisa kupisa kweiyo simende carbides kwakakwira kupfuura YG kirasi, uye simba rekukotama uye kusimba kwekuita kwakadzikira zvishoma.Nekuwedzera kweTiC zvemukati, kuoma, kupisa kupisa uye kupfeka kuramba kwechinhu kuri kuita zvirinani uye zvirinani, ukuwo simba rekukotama uye kuoma kwesimba kuchideredzwa.
YT mhando yecemented carbide inogona kazhinji kushandiswa kukwira-kumhanya kucheka kwesimbi.
M kirasi yakaenzana neChina's tungsten-titanium-tantalum (niobium) cobalt cemented carbide, codenamed YW kirasi, iyo inowedzerwa imwe yemukati yeTaC kana NbC mukuumbwa kweiyo simende carbide iri pamusoro kuitira kuvandudza kuomarara kwepamusoro-tembiricha, kusimba kwepamusoro-tembiricha uye abrasion kuramba yecemented carbide zvinhu.
YW kirasi inoratidzirwa ne: kuita kwakanaka kwese kwese, kwakasiyana siyana kwekushandisa, inogona kushandiswa kune ese marudzi esimbi yakakandwa, simbi, simbi isina tsvina uye yakakwirira tembiricha alloy processing.
Nekuramba kuri kubuda kweakasiyana-siyana emhando yezviyo yakasimwa carbide uye yakavharwa simende zvinhu zvecarbide, kuita kwecemented carbide zvinhu kwakavandudzwa zvakanyanya, uye kusimba kwekushanduka, kusimba kwekuita uye kupfeka kuramba kwecemented carbide kwakagadziridzwa zvakanyanya, uye simende carbide. yakatangawo kushandiswa muhuwandu hwakakura mumunda wemidziyo yakaoma yekucheka, senge madrill, reamers, tepi, milling cutters, hobs, uye broaches, nezvimwewo, izvo zvese zvakatanga kugadzirwa nehuwandu hukuru hwecemented carbide zvinhu. .
Kambani yedu inonyanya kugadzira Carbide Rotary File, Carbide rods, Carbide Scraper Blade,Carbide Corrugated Slitter Knife,Carbide Woodworking Replaceable Blade uye zvimwe zvigadzirwa zveCemented Carbide.
