Cemented Carbide yimveliso metallurgy umgubo sintered ukusuka ukuqina eliphezulu, refractory metal compound powder (ezifana WC, TiC, TaC, NbC kunye nezinye carbides eliphezulu lobushushu) kunye nebinder metal (Co, Mo, Ni, njl.).Njengoko ukubunjwa kweCemented Carbide kuqulethe inani elikhulu leekhabhidi ezinezinga eliphezulu lokunyibilika, ubunzima obuphezulu kunye nokuzinza kweekhemikhali ezilungileyo, ukuqina, ukuxhatshazwa kokugqoka kunye nokumelana nokushisa kweCemented Carbide kuphezulu kakhulu.Ubulukhuni beqondo lobushushu begumbi leCemented Carbide ngokuqhelekileyo yi-89 ~ 93HRA, elingana ne-78 ~ 82HRC, kwaye iqondo lokushisa elivumelekileyo lokusika liphezulu njenge-800 ℃ ~ 1000 ℃, kwaye ubulukhuni bayo buhlala bungama-77 ~ 85HRA nakwi-540 ℃, ilingana nobulukhuni beqondo lobushushu begumbi lentsimbi enesantya esiphezulu.
Ngoko ke, ukusebenza kokusika kwe-Cemented Carbide kuphezulu kakhulu kune-HSS, phantsi kokuqina okufanayo, isantya sokusika i-Cemented Carbide sivunyelwe ukuba sibe ngamaxesha angama-4 ukuya kumaxesha e-10 aphezulu kune-HSS, kwaye isantya sokusika sinokufikelela ngaphezu kwe. I-100m / min, kwaye inokunqumla zonke iintlobo zezinto ezinzima kumatshini, njengentsimbi eqinile, engenakunqunyulwa ngezixhobo zokusika ze-HSS.Nangona kunjalo, ngenxa yamandla aphantsi okugoba (malunga ne-1/2 ~ 1/4 ye-HSS), ukuqina kwempembelelo (malunga (malunga ne- (1/8 ~ 1/30) ye-HSS) kunye nokusebenza kakubi, ke ngoko, ngoku, izixhobo ze-Cemented Carbide ubukhulu becala isetyenziswa kwimveliso non-ikhefu ukusika kunye nezixhobo machining kunye imilo edge elula kwaye akukho mpembelelo.Xa umxholo we-carbide kwi-carbide ene-cemented iphezulu, ubunzima buphezulu, kodwa amandla e-flexural aphantsi;xa umxholo we-binder uphezulu, amandla e-flexural aphezulu kwaye ubunzima buphantsi.I-ISO iya kwahlulwa ibe yi-P, K kunye ne-M iindidi ezintathu ze-carbide ene-cemented, icandelo eliphambili leendidi ezintathu ze-cemented carbide yi-WC, eyaziwa ngokuba yi-WC-based cemented carbide.
Iklasi ye-K ilingana ne-tungsten-cobalt ye-cemented carbide yaseTshayina, igama lekhowudi engu-YG, ikakhulu liqulunqwe yi-WC kunye ne-Co.
Uhlobo lwe-YG lwamandla okugoba e-carbide kunye nokuqina kwempembelelo zingcono, zilungele ukusetyenzwa kwezinto ezinqabileyo, zingasetyenziselwa intsimbi ekhatywayo, isinyithi esingenasinyithi kunye ne-alloys yazo kunye ne-non-metallic materials processing.YG uhlobo lwe-carbide ene-cemented kunye nokwanda kwe-cobalt umxholo, ubulukhuni bayo buyancipha, ngelixa amandla okugoba enyuka, ukukwazi ukumelana nempembelelo yokuphucula ukugoba, okufanelekileyo kwi-machining rough.Ngokuchasene noko, ukuqina, ukunyanzeliswa kokugqoka kunye nokunyuka kokushisa ukunyuka, okufanelekileyo ukugqiba.
Iklasi ye-P ilingana ne-tungsten yaseChina, i-cobalt kunye ne-titanium cemented carbide, igama lekhowudi ye-YT, ukubunjwa kwayo ngaphezu kwe-WC kunye ne-Co, kodwa iqulethe i-5% ~ 30% ye-TiC, kuba ubunzima kunye nendawo yokunyibilika kwe-TiC iphezulu kune-WC. , ngoko ke ukuqina, ukuxhathisa ukunxiba kunye nokumelana nobushushu kwe-carbides enesamente ephezulu kuneklasi ye-YG, kwaye amandla okugoba kunye nokuqina kwempembelelo kuphantsi kancinci.Ngokunyuka komxholo we-TiC, ukuqina, ukumelana nobushushu kunye nokumelana nokunxiba kwezinto kuya kuba ngcono kwaye kube ngcono, ngelixa amandla okugoba kunye nokuqina kwempembelelo kuncipha.
Uhlobo lwe-YT ye-carbide ene-cemented ingasetyenziselwa ngokubanzi ukusika i-high-speed yentsimbi.
Iklasi ye-M ilingana ne-China ye-tungsten-titanium-tantalum (niobium) i-cobalt ye-cemented carbide, iklasi ye-YW enekhowudi, eyongezwa umxholo othile we-TaC okanye i-NbC ekubunjweni kwe-carbide enesamente engentla ukwenzela ukuphucula ukuqina kobushushu obuphezulu, amandla aphezulu obushushu kunye nokuxhatshazwa kwe-abrasion ye-cemented carbide material.
Iklasi ye-YW ibonakaliswe ngu: ukusebenza kakuhle ngokubanzi, uluhlu olubanzi lwezicelo, lunokusetyenziswa kuzo zonke iintlobo zentsimbi, intsimbi, insimbi engenasici kunye nokushisa okuphezulu kwe-alloy processing.
Ngokuqhubekayo kokuvela kwezinto ezahlukeneyo ze-ultra-fine ze-cemented cemented carbide kunye ne-cemented cemented carbide materials, ukusebenza kwe-cemented carbide kuye kwaphuculwa kakhulu, kwaye amandla okuguquguquka, ukuqina kwempembelelo kunye nokunganyangeki kwe-cemented carbide kuye kwaphuculwa kakhulu, kunye ne-cemented carbide. sele iqalile ukusetyenziswa ngobuninzi kwintsimi yezixhobo zokusika eziyinkimbinkimbi, ezifana ne-drill, i-reamers, iitephu, i-milling cutters, i-hobs, kunye ne-broaches, njl., zonke eziye zaqalwa ukwakhiwa ngobuninzi bezinto ze-carbide. .
Inkampani yethu ikakhulu ivelisa iFayile eRotayo yeCarbide, iintonga zeCarbide, iCarbide Scraper Blade, iCarbide Corrugated Slitter Knife, iCarbide Woodworking Replaceable Blade kunye nezinye iimveliso zeCarbide eziCetyiweyo.
