Cemented Carbide ndi ufa zitsulo zopangidwa sintered kuchokera kuuma mkulu, refractory zitsulo pawiri ufa (monga WC, TiC, TaC, NbC ndi zina mkulu-kutentha carbides) ndi zitsulo binder (Co, Mo, Ni, etc.).Popeza mapangidwe a Cemented Carbide ali ndi ma carbides ambiri okhala ndi malo osungunuka kwambiri, kuuma kwakukulu komanso kukhazikika kwamankhwala abwino, kulimba, kukana kuvala komanso kukana kutentha kwa Cemented Carbide ndizokwera kwambiri.Kutentha kwa chipinda cha Cemented Carbide nthawi zambiri ndi 89 ~ 93HRA, yomwe ndi yofanana ndi 78 ~ 82HRC, ndipo kutentha kovomerezeka kovomerezeka ndipamwamba kwambiri mpaka 800 ℃ ~ 1000 ℃, ndipo kuuma kwake kumakhalabe 77 ~ 85HRA ngakhale pa 540 ℃, yomwe ndizofanana ndi kuuma kwa kutentha kwa chipinda chachitsulo chothamanga kwambiri.
Choncho, ntchito yodula ya Cemented Carbide ndiyokwera kwambiri kuposa HSS, pansi pa kukhazikika komweko, kuthamanga kwa Cemented Carbide kumaloledwa kukhala nthawi 4 mpaka 10 kuposa HSS, ndipo kuthamanga kwachangu kumatha kufika kuposa. 100m / min, ndipo imatha kudula mitundu yonse ya zida zolimba ku makina, monga zitsulo zolimba, zomwe sizingadulidwe ndi zida za HSS.Komabe, chifukwa cha mphamvu yopindika yotsika (pafupifupi 1/2 ~ 1/4 ya HSS), kulimba kwamphamvu (pafupifupi (1/8~1/30) ya HSS) ndi kusapanga bwino, chifukwa chake, pakadali pano, zida za Cemented Carbide ndi zomwe zimagwiritsidwa ntchito kwambiri popanga zida zodulira nthawi zonse komanso zopangira makina okhala ndi mawonekedwe osavuta a m'mphepete komanso osakhudzidwa.Pamene carbide zili mu simenti carbide ndi mkulu, kuuma ndi mkulu, koma flexural mphamvu ndi otsika;pamene binder zili pamwamba, mphamvu flexural ndi mkulu ndipo kuuma ndi otsika.ISO idzagawidwa mu P, K ndi M magulu atatu a carbide cemented, chigawo chachikulu cha magulu atatu a carbide cemented ndi WC, omwe amadziwika kuti WC-based cemented carbide.
Kalasi ya K ndi yofanana ndi carbide yaku China yopangidwa ndi tungsten-cobalt, code name YG, yopangidwa makamaka ndi WC ndi Co.
YG mtundu wa cemented carbide kupinda mphamvu ndi kulimba zimakhudza bwino, oyenera Chimaona zinthu processing, angagwiritsidwe ntchito chitsulo choponyedwa, zitsulo sanali achitsulo ndi kasakaniza wazitsulo ndi sanali zitsulo zitsulo processing.YG mtundu wa simenti carbide ndi kuwonjezeka kwa cobalt okhutira, kuuma kwake kumachepa, pamene mphamvu yopindika imawonjezeka, kukhoza kupirira mphamvu ya kupititsa patsogolo kwa roughing, koyenera kuyika makina ovuta.M'malo mwake, kuuma, kuvala kukana ndi kukana kutentha kumawonjezeka, koyenera kumaliza.
Gulu la P ndilofanana ndi tungsten ya China, cobalt ndi titaniyamu cemented carbide, code name YT, kapangidwe kake kuwonjezera pa WC ndi Co, komanso ili ndi 5% ~ 30% ya TiC, chifukwa kuuma ndi kusungunuka kwa TiC ndikokwera kuposa WC. , kotero kuuma, kukana kuvala ndi kukana kutentha kwa ma carbides opangidwa ndi simenti ndi apamwamba kuposa gulu la YG, ndipo mphamvu yopindika ndi kulimba kwake ndizotsika pang'ono.Ndi kuchuluka kwa zinthu za TiC, kuuma, kukana kutentha ndi kukana kwa zinthuzo kukuyenda bwinoko, pomwe mphamvu yopindika ndi kulimba kwamphamvu kumachepetsedwa.
Mtundu wa YT wa carbide wopangidwa ndi simenti nthawi zambiri ukhoza kugwiritsidwa ntchito podula chitsulo chothamanga kwambiri.
M kalasi ndi lofanana ndi tungsten-titanium-tantalum (niobium) cobalt simenti carbide China, codenamed YW kalasi, amene anawonjezera zina zili TaC kapena NbC mu zikuchokera carbide simenti pamwamba kuti kusintha mkulu kutentha kuuma, Kutentha kwambiri kwamphamvu komanso kukana kwa abrasion kwa zinthu zokhala ndi simenti ya carbide.
Gulu la YW limadziwika ndi: ntchito yabwino yonse, ntchito zosiyanasiyana, zingagwiritsidwe ntchito pamitundu yonse yazitsulo, zitsulo, zitsulo zosapanga dzimbiri komanso kutentha kwa alloy processing.
Ndi kutuluka kosalekeza kwa mitundu yosiyanasiyana ya mbewu zabwino kwambiri zokhala ndi simenti ya carbide ndi zida zokutira zomata, magwiridwe antchito a simenti ya carbide akhala akuyenda bwino kwambiri, ndipo mphamvu yosunthika, kulimba kwamphamvu komanso kukana kuvala kwa simenti ya carbide yasinthidwa kwambiri, ndipo carbide yomata. wayambanso kugwiritsidwa ntchito mochulukira m'munda wa zida zovuta kudula, monga kubowola, reamers, matepi, mphero cutters, hobs, ndi broaches, etc., amene onse ayamba kupangidwa ndi unyinji wa simenti zipangizo carbide. .
Kampani yathu imapanga kwambiri Carbide Rotary File, Carbide rods, Carbide Scraper Blade,Carbide Corrugated Slitter Knife,Carbide Woodworking Replaceable Blade ndi zinthu zina za Cemented Carbide.
