Bubble Alumina Refractory Bricks yeIndustrial Furnace
Features
Bubble alumina zvidhinha zvine akati wandei akasarudzika maficha:
1. **High Thermal Insulation**:Kudzikira kwavo kwekupisa kwekushisa kunoita kuti ive yakanakisa insulators, kuderedza kurasikirwa kwekupisa munzvimbo dzakanyanya kupisa.
2. **Kuchena Kwepamusoro**:Yakagadzirwa kubva ku-high-purity alumina, izvi zvidhinha zvinopa kushanda kwepamusoro mumamiriro ezvinhu akanyanyisa.
3. **Chiremu**:Kubatanidzwa kwealumina bubbles kunoderedza kuwanda kwese, zvichiita kuti zvidhinha zvive nyore uye zviri nyore kubata nekuisa.
4. **Kuramba Kupisa Kwepamusoro **:Dzinogona kumira kutonhora kwakanyanya, kazhinji pamusoro pe1800 ° C, zvichiita kuti dzive dzakakodzera kushandiswa mumavira ekupisa uye honi.
5. **Corrosion Resistance**:Vane kumira kwakanaka kukurwisa kwemakemikari, kunyanya kubva kune slags uye simbi dzakanyungudutswa.
6. **Kuwedzera Kwekupisa Kwepasi**:Iyi ficha inobatsira kuchengetedza kurongeka kwechimiro uye inoderedza njodzi yekutsemuka pasi pekupisa bhasikoro.
7. **Mechanical Simba**:Pasinei nekureruka, vanopa simba rakanaka remagetsi uye kusimba pasi pemamiriro ekushanda.
Aya maficha anoita bubble alumina zvidhinha zvakanyanya kubatsira mumaindasitiri akaita sesimbi, ceramics, uye kugadzira magirazi.
Typical Application
Inoshandiswa zvakanyanya mumaindasitiri akadai semetallurgical, refractories, ceramics, petrochemical, girazi, magetsi, etc. Yayo inogona kushandiswa seyakapisa face refractory lining ye pyrolizer, inopisa blast furnace, moto unopisa, tunnel kil, pushed slab kiln, crucible furnace. , choto chemagetsi, nezvimwewo.
