I-Chrome corundum

I-Chrome corundum (eyaziwa nangokuthi i-pink corundum) yenziwe nge-metallurgical grade chrome eluhlaza kanye ne-alumina yezimboni njengezisetshenziswa zokusetshenziswa, futhi isabela ngokwekhemikhali ezingeni lokushisa eliphezulu elingaphezu kwama-degree angu-2000.Inani elithile le-chromium oxide liyengezwa phakathi nenqubo yokuncibilika, okunsomi ngokukhanyayo noma i-rose.

Ukusebenza okuphelele kwemikhiqizo ye-chromium corundum kunezici zokuqina okuphezulu, ukuqina okuphezulu, ukuhlanzeka okuphezulu, ukuzilola okuhle kakhulu, ikhono eliqinile lokugaya, ukukhiqiza ukushisa okuphansi, ukusebenza kahle okuphezulu, ukumelana ne-asidi ne-alkali, ukumelana nokushisa okuphezulu, nokuzinza okuhle kokushisa.

Ku-chromium corundum, ukwethulwa kwe-elementi ye-Cr kuthuthukisa ukuqina kwe-abrasive.Ukuqina kufana nokwe-corundum emhlophe, futhi ukuqina kuphakeme kunokwe-corundum emhlophe.Amathuluzi abrasive akhiqizwa yiyo anokuqina okuhle nokuqeda okuphezulu.Kusetshenziswa kakhulu kuma-abrasives, ukugaya, izinto zokupholisha, isihlabathi sokupholisha ngokunemba, izinto zokufafaza, izithwali zekhemikhali ze-catalyst, izitsha zobumba ezikhethekile, njll. Izinkambu ezisebenzayo zibandakanya: ukugaya okunembayo kwamathuluzi okulinganisa, ama-spindle amathuluzi omshini, izingxenye zamathuluzi, ama-workpieces anentambo, nokugaya imodeli. .

I-chromium corundum ine-viscosity ephezulu kanye nokumelana okuhle kokungena ngenxa yengxenye yengilazi equkethe i-chromium oxide, engavimbela kakhulu ukuguguleka nokungena kwe-slag encibilikisiwe.Ibuye isetshenziswe kabanzi ezindaweni zokushisa eziphakeme ezinemvelo enokhahlo, okuhlanganisa izithando zensimbi ezingenayo i-ferrous, izibani ezincibilikisa ingilazi, ama-carbon black reactors, izishisi zikadoti, izinsimbi eziphikisayo kanye nokunye ukumelana nokushisa okuphezulu nokuvikelwa kokugqwala.
