I-Cemented Carbide ingumkhiqizo we-metallurgy oyimpushana oxutshwe ngobulukhuni obuphezulu, i-refractory metal compound powder (njenge-WC, i-TiC, i-TaC, i-NbC namanye ama-carbides ashisa kakhulu) kanye ne-metal binder (Co, Mo, Ni, njll.).Njengoba ukwakheka kwe-Cemented Carbide kuqukethe inani elikhulu lama-carbides anephuzu eliphakeme lokuncibilika, ubulukhuni obuphezulu kanye nokuzinza okuhle kwamakhemikhali, ukuqina, ukumelana nokugqoka kanye nokumelana nokushisa kwe-Cemented Carbide kuphezulu kakhulu.Ubulukhuni bezinga lokushisa legumbi le-Cemented Carbide ngokuvamile bungu-89 ~ 93HRA, okulingana no-78~82HRC, futhi izinga lokushisa elivumelekile lokusika liphezulu njengo-800 ℃ ~ 1000 ℃, futhi ubulukhuni bayo busahlala bu-77 ~ 85HRA ngisho naku-540 ℃, okuyinto ilingana nobulukhuni bezinga lokushisa kwegumbi lensimbi enesivinini esikhulu.
Ngakho-ke, ukusebenza kokusika kwe-Cemented Carbide kuphakeme kakhulu kune-HSS, ngaphansi kokuqina okufanayo, ijubane lokusika le-Cemented Carbide livunyelwe ukuba libe izikhathi ezingu-4 kuya kwezingu-10 ngaphezu kwe-HSS, futhi isivinini sokusika singafinyelela ngaphezu kwalokho. 100m/min, futhi ingasika zonke izinhlobo zezinto ezisebenza kanzima emshinini, njengensimbi eqinile, engakwazi ukusikwa ngamathuluzi okusika e-HSS.Kodwa-ke, ngenxa yamandla ayo okugoba aphansi (cishe i-1/2~1/4 ye-HSS), ukuqina komthelela (cishe (1/8~1/30) we-HSS) nokungasebenzi kahle, ngakho-ke, okwamanje, izinto ze-Cemented Carbide ikakhulukazi asetshenziswa ekukhiqizeni amathuluzi okusika kanye nama-machining angahlali ngezikhathi ezithile anomumo olula wonqenqema futhi awukho umthelela.Lapho okuqukethwe kwe-carbide ku-carbide enosimende kuphezulu, ubulukhuni buphezulu, kodwa amandla okuguquguquka aphansi kakhulu;lapho okuqukethwe kwe-binder kuphezulu, amandla okuguquguquka aphezulu futhi ubulukhuni buphansi.I-ISO izohlukaniswa ibe yi-P, K kanye ne-M izigaba ezintathu ze-carbide enosimende, ingxenye eyinhloko yezigaba ezintathu ze-carbide enosimende yi-WC, eyaziwa ngokuthi yi-WC-based cemented carbide.
I-K class ilingana ne-tungsten-cobalt cemented carbide yaseChina, igama lekhodi elithi YG, elakhiwe ikakhulukazi i-WC ne-Co.
Uhlobo lwe-YG lwamandla okugoba e-carbide kasimende kanye nokuqina komthelela zingcono, zilungele ukucubungula izinto eziphukayo, zingasetshenziselwa insimbi ecijile, izinsimbi ezingezona ezoni kanye nama-alloys azo kanye nokucubungula izinto ezingezona ezensimbi.Uhlobo lwe-YG lwe-carbide enosimende ngokukhuphuka kwe-cobalt okuqukethwe, ubulukhuni bayo buyehla, kuyilapho amandla okugoba ekhula, ikhono lokumelana nomthelela wokuthuthukiswa kokumaholosha, okulungele ukukhanda amakhanda.Ngokuphambene nalokho, ubunzima, ukumelana nokugqoka kanye nokumelana nokushisa kwanda, okulungele ukuqeda.
Ikilasi le-P lilingana ne-tungsten yaseChina, i-cobalt ne-titanium cemented carbide, igama lekhodi engu-YT, ukwakheka kwayo ngaphezu kwe-WC ne-Co, kodwa futhi iqukethe u-5% ~ 30% we-TiC, ngenxa yokuthi ukuqina nendawo yokuncibilika kwe-TiC kungaphezu kwe-WC. , ngakho-ke ukuqina, ukumelana nokugqoka kanye nokumelana nokushisa kwama-carbides kasimende anjalo kuphakeme kunesigaba se-YG, futhi amandla okugoba kanye nokuqina komthelela kuphansi kancane.Ngokukhula kokuqukethwe kwe-TiC, ubulukhuni, ukumelana nokushisa nokumelana nokugqokwa kwezinto ezibonakalayo kuba ngcono futhi kuba ngcono, kuyilapho amandla okugoba nokuqina komthelela kuncipha.
Uhlobo lwe-YT lwe-carbide enosimende ngokuvamile lungasetshenziselwa ukusika insimbi ngesivinini esikhulu.
I-M class ilingana ne-tungsten-titanium-tantalum (niobium) yaseChina i-cobalt cemented carbide, isigaba esinekhodi ye-YW, enezelwa okuqukethwe okuthile kwe-TaC noma i-NbC ekwakhekeni kwe-carbide enosimende engenhla ukuze kuthuthukiswe ubulukhuni bezinga lokushisa eliphezulu, Amandla okushisa aphezulu kanye nokumelana nokuhuzuka kwe-carbide ehlanganisiwe.
Isigaba se-YW sibonakala ngokuthi: ukusebenza kahle okuphelele, uhla olubanzi lwezinhlelo zokusebenza, lungasetshenziselwa zonke izinhlobo zensimbi ekhonjiwe, insimbi, insimbi engagqwali kanye nokucubungula okuphezulu kwe-alloy.
Ngokuvela okuqhubekayo kwezinhlobonhlobo ze-carbide zikasimende ezisanhlamvu ezinhle kakhulu kanye nezinto ze-carbide zikasimende zenziwe ngcono kakhulu, futhi amandla aguquguqukayo, ukuqina komthelela kanye nokumelana nokugqokwa kwe-carbide enosimende kuye kwathuthukiswa kakhulu, kanye ne-carbide enosimende. isiqalile futhi ukusetshenziswa ngobuningi emkhakheni wamathuluzi okusika ayinkimbinkimbi, njengama-drill, ama-reamers, ompompi, ama-milling cutters, ama-hobs, nama-broaches, njll., wonke aseqalile ukwakhiwa ngenani elikhulu lezinto ze-carbide zikasimende. .
Inkampani yethu ikhiqiza ikakhulukazi iCarbide Rotary File, Carbide rods, Carbide Scraper Blade,Carbide Corrugated Slitter Knife,Carbide Woodworking Replaceable Blade neminye imikhiqizo ye-Cemented Carbide.
