Corundum Bricks-Hengli
Features
Corundum zvidhinha, inozivikanwawo sealumina zvidhinha, ndeye yakakwirira-alumina refractory zvigadzirwa zvine akati wandei akakosha maficha:
1. **Kuchena Kwepamusoro: **Kazhinji inoumbwa neanopfuura 90% alumina (Al2O3), ichivimbisa yakanakisa refractory zvivakwa.
2. **Kuramba Kupisa Kwepamusoro: **Inokwanisa kutsungirira tembiricha inosvika 1900 ° C, ichiita kuti ive yakakodzera kune yakanyanya kudiwa nzvimbo dzekupisa.
3. **Mechanical Simba: **Zvidhinha zveCorundum zvine simba rakanyanya rekumanikidza uye zvakanaka kupfeka kuramba, zvichivagonesa kubata mitoro inorema uye abrasive mamiriro.
4. **Kuramba Corrosion: **Vanodzivisa kuora kubva kune slags, acids, alkalis, uye mamwe makemikari, vachiwedzera hupenyu hwavo munzvimbo dzakaoma.
5. **Low Porosity: **Low porosity inobatsira kudzivirira kupinda kwezvinhu zvakanyungudutswa uye magasi, kuwedzera kusimba uye kupisa kwemafuta ekudzivirira.
6. **Thermal Stability: **Ivo vanoratidza yakanakisa kugadzikana kwemafuta uye kuramba kuvhunduka kwekupisa, uko kwakakosha kune maitiro anosanganisira nekukurumidza kuchinja kwekushisa.
7. **Dimensional Kugadzikana: **High alumina content inovimbisa kuti zvidhinha zvinochengetedza chimiro chavo uye huwandu pakupisa kwakanyanya, kudzivirira kukanganisa kwemaitiro.
Aya maficha anoita kuti zvidhinha zvecorundum zvive zvakanaka kuti zvishandiswe mumhando dzakasiyana-siyana dzekupisa kupisa, zvinosanganisira kuputika kwemoto, hot blast stoves, simbi ladles, uye mamwe maindasitiri emoto uye honi.
Typical Application
Inoshandiswa zvakanyanya mumaindasitiri akadai sefetiraiza, electro ceramics, petrochemical, simbi, foundry, alloy simbi, refractories, etc. Yakajairika application yakadai seyechipiri reformer uye gasi jenareta lining, catalyst bed support, channel induction furnace, reheating furnace hearth, etc.
