Yakakwira alumina simende inogadzirwa nekusanganisa yakasarudzika zvinhu muSpecial choto. Mushure mekutonhodza, clinker inogayiwa uchishandisa bhora. Izvo zvigadzirwa zveyakakwira alumina refractory simende CA-70 yakakwirira kuchena karusiyamu zvinhu uye yakakwirira yakachena alumina. Zvinhu zvakasvibirira zvinofanira kusanganiswa maererano nechiyero chakakodzera. Iyo mbishi inofanira kupiswa kuti isaite fuse. Zvinyorwa zveAl2O3 zvinowanzodzorwa mukati me68% kusvika 72%. Iwo makuru makomba ayo CA uye CA2.
1.Kuita kwakanaka kune kuvhunduka kwekupisa, ngura, kukukurwa uye abrasion kuramba,
2.High refractoriness uye yakanakisa mechanical simba,
3.Both intermittently uye inoramba ichishanda mode inogamuchirwa, inoderedza kutsemuka kwe lining,
4.Kureba uye kugadzikana kwehupenyu kutenderera kusvika kune yakakwira kunyatsoshanda,
5.Suit yemarudzi ose emhando dzesimbi, kuderedza zvakasara uye porosity yezvigadzirwa,
6.Kushanda uye kuchengetedza mari kuburikidza nekugadzirisa nekugadzirisa zviri nyore.

High alumina simenti inonyanya kushandiswa mune zvakakosha zvinodiwa zvekuvakwa kwekukurumidzira, kugadzirisa kwekukurumidzira, sulfate kuramba uye kuvaka kwechando. Uye yakakwira alumina refractory simende inonyanya kushandiswa mukukurumidzira mapurojekiti, senge kudzvanywa kudzivirira, mugwagwa uye yakakosha kugadzirisa zvirongwa. Zvakare yakakwirira alumina moto simende inoshandiswa munzvimbo inotevera:
RS refractory fekitori inyanzvi yakakwira alumina refractory simende mutengesi iyo yakavambwa mukutanga 90s yemakumi maviri emakore. RS refractory fekitori ine nyanzvi mune yakakwira alumina simende kweanopfuura makore makumi maviri. kana uine chimwe chinodiwa che high alumina refractory simenti, kana uine mibvunzo pa zircon mulite refractory bricabout zviratidzo zvemuviri nemakemikari, ndapota taura nesu mahara. uye Rs refractory fekitori senyanzvi zircon mulite refractory zvidhinha muchina, ine mamwe mabhenefiti emakwikwi seanotevera:
