Ubwino, kuipa, ndi kusiyana pakati pa chitsulo chothamanga kwambiri ndi simenti ya carbide

1. Chitsulo chothamanga kwambiri:

Chitsulo chothamanga kwambiri ndi chitsulo cha carbon ndi high-alloy steel. Malinga ndi kapangidwe ka mankhwala, akhoza kugawidwa mu tungsten mndandanda ndi molybdenum mndandanda zitsulo, ndipo malinga ndi ntchito kudula, akhoza kugawidwa mu zitsulo wamba mkulu-liwiro ndi mkulu-ntchito mkulu-liwiro zitsulo. Chitsulo chothamanga kwambiri chiyenera kulimbikitsidwa ndi chithandizo cha kutentha. M'malo ozimitsidwa, chitsulo, chromium, gawo la tungsten, ndi kaboni muzitsulo zothamanga kwambiri zimapanga carbides zolimba kwambiri, zomwe zingapangitse kukana kwachitsulo (kuuma kumatha kufika HRC64-68).

Mbali ina ya tungsten imasungunuka mu matrix ndikuwonjezera kuuma kofiira kwachitsulo. Kuuma kofiira kwachitsulo chothamanga kwambiri kumatha kufika madigiri 650. Chitsulo chothamanga kwambiri chimakhala ndi mphamvu zabwino komanso zolimba. Pambuyo pakunola, m'mphepete mwake mumakhala wakuthwa ndipo mtundu wake umakhala wokhazikika. Nthawi zambiri amagwiritsidwa ntchito popanga zida zazing'ono, zowoneka movutikira.

2. Carbide yopangidwa ndi simenti:

Cemented carbide ndi micron-order refractory high-hardness metal carbide powder, yomwe imapangidwa ndi kuwombera pa kutentha kwakukulu ndi kuthamanga kwambiri ndi cobalt, molybdenum, faifi tambala, ndi zina zotero monga binder. Zomwe zili mu carbide zotentha kwambiri mu carbide yopangidwa ndi simenti zimaposa zitsulo zothamanga kwambiri, zolimba kwambiri (HRC75-94) komanso kukana kuvala bwino.

Kuuma kofiira kolimba kumatha kufika madigiri 800-1000. Kuthamanga kwa simenti ya carbide ndi 4-7 nthawi zambiri kuposa chitsulo chothamanga kwambiri. Mkulu kudula bwino.

Carbide yokhala ndi simenti imakhala ndi kuuma kwambiri, mphamvu, kukana kuvala, komanso kukana dzimbiri, ndipo imadziwika kuti "mano ogulitsa". Amagwiritsidwa ntchito popanga zida zodulira, mipeni, zida za cobalt, ndi mbali zosagwira, ndipo amagwiritsidwa ntchito kwambiri m'magulu ankhondo, zakuthambo ndi ndege, Mechanical processing, metallurgy, pobowola mafuta, zida zamigodi, kulumikizana kwamagetsi, zomangamanga, ndi zina. ndi chitukuko cha mafakitale otsika, kufunikira kwa msika wa carbide simenti kukukulirakulira. Ndipo m'tsogolomu, kupanga zida zamakono ndi zipangizo zamakono, kupita patsogolo kwa sayansi ndi luso lamakono, komanso kukula kwachangu kwa mphamvu za nyukiliya kudzawonjezera kufunikira kwa zinthu zamtengo wapatali, komanso zokhazikika zokhazikika za carbide. .
