Mavuto Wamba Ndi Kusanthula Chifukwa Chakukakamiza Kwa Simenti Ya Carbide

Cemented carbide ndi aloyi wopangidwa ndi chitsulo cholimba chachitsulo chosakanizira ndi zitsulo zomangira kudzera muzitsulo za ufa.Lili ndi katundu wa kuuma kwakukulu, kukana kuvala, mphamvu ndi kulimba.Chifukwa cha mawonekedwe ake apadera, nthawi zambiri amagwiritsidwa ntchito popanga zida zoboola miyala, zida zamigodi, zida zoboola, zida zoyezera ndi zina zotero.Amagwiritsidwa ntchito kwambiri mu mafuta ndi gasi, makampani opanga mankhwala, makina omanga, kulamulira madzimadzi ndi zina.Cemented carbide ndi chinthu choponderezedwa ndi zitsulo za ufa.Lero, Chuangrui akufotokozerani zovuta zazikulu zingapo zomwe timakumana nazo nthawi zambiri, ndikusanthula zifukwa zake.

1. Chomwe chimapangitsa kuti zinyalala zomwe zimakanikizidwa kwambiri pamakina osindikizira a carbide ndi delamination

Kuwonekera m'mphepete mwa chipika choponderezedwa, pa ngodya ina kupita kumtunda wapamwamba, kupanga mawonekedwe abwino kumatchedwa delamination.Zambiri mwazosanjikiza zimayambira pamakona ndikufikira ku compact.Chifukwa cha delamination ya yaying'ono ndi zotanuka mkati kupsyinjika kapena zotanuka nyonga mu yaying'ono.Mwachitsanzo, cobalt zomwe zili mu osakaniza ndizochepa, kuuma kwa carbide ndipamwamba, ufa kapena tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono, kapena kugawa sikufanana, kusakaniza kumakhala konyowa kwambiri kapena kouma kwambiri, kukakamiza kukanikiza ndi kwakukulu, kulemera kwa unit ndi kwakukulu kwambiri, ndipo mphamvu yokakamiza ndiyokwera kwambiri.Mawonekedwe a chipika ndi ovuta, kutsirizitsa kwa nkhungu kumakhala kosauka kwambiri, ndipo pamwamba pa tebulo ndi yosafanana, zomwe zingayambitse delamination.

Chifukwa chake, kuwongolera mphamvu ya chophatikizika ndikuchepetsa kupsinjika kwamkati ndi mluzu wammbuyo wa compact ndi njira yabwino yothetsera delamination.

2. Chodabwitsa cha uncompressed (kuwonetseredwa particles) zidzachitikanso pa kukanikiza ndondomeko simenti carbide.

Chifukwa kukula kwa ma pores a compact ndiakulu kwambiri, sikungatheke kwathunthu panthawi ya sintering, zomwe zimapangitsa kuti ma pores apadera azikhala otsalira mu thupi la sintered.Ma pellets ndi olimba kwambiri, ma pellets ndi ovuta kwambiri, ndipo zinthu zotayirira zimakhala zazikulu kwambiri;ma pellets otayirira amagawidwa mosagwirizana m'bowo, ndipo kulemera kwake kumakhala kochepa.zingayambitse uncompressed.

3. Chinthu china chodziwika bwino cha zinyalala pakukanikiza simenti ya carbide ndi ming'alu

Chochitika cha kuthyoka kwapang'onopang'ono kwapang'onopang'ono kumatchedwa crack.Chifukwa kupsinjika kwamphamvu mkati mwa compact ndikokulirapo kuposa mphamvu yolimba ya compact.Kupanikizika kwamkati kwa compact kumachokera ku zotanuka zamkati mkati.Zinthu zomwe zimakhudza delamination zimakhudzanso kusweka.Njira zotsatirazi zingatengedwe kuti muchepetse kuphulika kwa ming'alu: kutalikitsa nthawi yogwira kapena kukakamiza kangapo, kuchepetsa kupanikizika, kulemera kwa unit, kukonza mapangidwe a nkhungu ndikuwonjezera makulidwe a nkhungu moyenerera, kufulumizitsa kuthamanga, kuonjezera kuumba wothandizila, ndi kuonjezera chochuluka kachulukidwe zakuthupi.

Njira yonse yopangira simenti ya carbide ndiyofunikira kwambiri.Zhuzhou Chuangrui Cemented Carbide Co., Ltd. yakhazikika pakupanga simenti ya carbide kwa zaka 18.Ngati muli ndi mafunso okhudza kupanga simenti ya carbide, chonde tcherani khutu patsamba lovomerezeka la Chuangrui.
