2022 njerwa yatsopano ya chrome corundum

Ubwino wazogulitsa: kutsika kochepa, kachulukidwe kakang’ono, mphamvu yayikulu, kutentha kwabwino kutentha, kukana kuzizira kwambiri ndi kutentha kwakukulu, kukana kwabwino kwa slag, ndi kukhazikika kwabwino.

Mafotokozedwe Akatundu

Njerwa za Chromium corundum zopangira zimapangidwa kuchokera ku Al2O3 yoyera komanso Cr2O3 ngati zida zopangira zazikulu. Poyerekeza ndi njerwa zoyera za corundum, ili ndi zinthu zabwino, monga Refractoriness, kutentha kwa mapindikidwe pansi pa katundu, mphamvu zosinthasintha, kutentha kwambiri, kutentha kwambiri kwa voliyumu Kutsutsana ndi kukana kutentha kwa slag.

Njerwa za Chrome corundum ndi njerwa za corundum zokhala ndi Cr2O3. Kutentha kwambiri, Cr2O3 ndi Al2O3 zimapanga yankho lolimba. Chifukwa chake, kutentha kwambiri kwa njerwa za chromium corundum ndibwino kuposa njerwa zoyera za corundum. Njerwa za chromium corundum zomwe zimagwiritsidwa ntchito mu ng’anjo ya gasification ya mafakitale a petrochemical ziyenera kukhala zotsika kwambiri, chitsulo chotsika, alkali yotsika, chiyero chokwanira, komanso kukhala ndi mphamvu komanso mphamvu. Njerwa za Chrome corundum zimagwiritsidwa ntchito kwambiri, ndipo zomwe zili mu Cr2O3 zimakhala pakati pa 9% mpaka 15%.

Njerwa za chrome corundum zimatchedwanso kuti chromium corundum yogwira njerwa. Ndi mankhwala apamwamba omwe amalimbikitsidwa pamsika mzaka zaposachedwa. Amapangidwa kuchokera ku aluminium yoyera Al2O3 ndi chromium oxide Cr2O3 ngati zida zazikulu zopangira. Poyerekeza ndi njerwa zoyera za corundum, ili ndi zinthu zabwino, monga Refractoriness, kutentha kutentha, Flexural mphamvu, kutentha kwambiri, kutentha kwambiri kwa voliyumu komanso kukana kwa slag. Njerwa za Chrome corundum ndi mtundu wa zinthu zosanja zotsika kwambiri, ndipo moyo wake wautumiki umatha kufikira miyezi 10 mpaka 18 anthu ambiri atagwiritsa ntchito mphero.

Kuyeserera kwawonetsa kuti kugwiritsa ntchito njerwa za chromium corundum zogwiritsira ntchito kwambiri panjira yolumikizira ng’anjo yotentha yotenthetsera ma billet akuluakulu, mikangano yayikulu pagawo lililonse komanso kutulutsa kwakukulu, sikuti kungangowonjezera moyo wautumiki wa kugogoda njira ndikuchepetsa kutseka kwa ng’anjo Nthawi, kuonjezera kupanga, kuchepetsa kugwiritsanso ntchito ndalama ndikukonzanso ndalama, komanso kuchepetsa kuchuluka kwa kuzirala kwachangu ndi kutentha komwe kumachitika chifukwa chatsekedwa m’ng’anjo kuti isungidwe, kuti moyo wonse wa ng’anjoyo ukhale wabwino, ndipo phindu lodziwika bwino lachuma lingapezeke.

Zizindikiro zakuthupi ndi zamankhwala
