Chrome corundum (inozivikanwawo sepink corundum) inogadzirwa nekemikari reaction ye metallurgical chrome-girini uye maindasitiri alumina pakupisa kwepamusoro pamusoro pe2000 degrees.Imwe huwandu hwechromium oxide inowedzerwa panguva yekunyungudika, inova yepepuru yakareruka kana yakasimuka.
Chromium corundum inokunda mukushanda kwakazara kunosanganisira kuoma kwepamusoro, kusimba kwepamusoro, kuchena kwepamusoro, kuzvirodza kwakanakisa, kugona kwakasimba kwekugaya, kugadzirwa kwakaderera, kushanda kwakanyanya, asidhi uye alkali kuramba, kupisa kwekushisa, uye kugadzikana kwakanaka kwekupisa.
Kuwedzerwa kwemakemikari chinhu Cr mu chrome corundum inovandudza kuoma kwezvishandiso zvayo zvinoputika.Iyo yakafanana newhite corundum mukuoma asi yakakwirira mukuoma.Zvishandiso zveAbrasive zvakagadzirwa nechrome corundum zvine kusimba kwakanaka uye kupedzisa kwepamusoro.Inoshandiswa zvakanyanya mukukwesha, kugaya, kupurisa, kunyatsokanda jecha, kupfapfaidza zvinhu, kemikari inotakura inotakura, yakakosha ceramics uye zvichingodaro.Minda inoshandisika inosanganisira: maturusi ekuyeresa, maturusi emuchina, maturusi emidziyo, kunyatsokuya mukugadzirwa kweshinda uye modhi.
Iyo chrome corundum ine yakakwira viscosity uye yakanaka permeability nekuda kweiyo chromium oxide-ine girazi chikamu, iyo inogona zvakanyanya kudzivirira kukukurwa uye kupinda kweyakanyungudutswa slag.Inoshandiswawo zvakanyanya muminda yekupisa yakanyanya ine hutsinye nharaunda, kusanganisira isina-ferrous metallurgy mavira, magirazi ekunyungudutsa mavira, carbon black reactors, marara incinerators uye refractory castables.
