Corundum Bricks-Hengli

Hengli Corundum Bricks yog tsim los ntawm high purity tabular alumina, fused alumina, sintered nyob rau hauv kub shuttle kiln. Cov cib muaj cov cim ntawm kev kub siab, siab purity, tsis muaj porosity, thiab zoo thermal poob siab tsis kam.
Hengli Corundum cib tuaj yeem tiv thaiv corrosion hauv oxidizing atmospheres thiab txo qis cua. Nws tuaj yeem tiv taus qhov kub siab hydrogen nres.
Hengli Corundum Brick muaj nyob rau hauv cov qauv cib qhov ntau thiab tsawg (ncaj, arches thiab wedges) nrog rau cov phiaj xwm kev cai thiab cov duab.

Nta

Corundum cib, tseem hu ua alumina cib, yog cov khoom siv siab alumina refractory nrog ntau yam tseem ceeb:

1. **High Purity: **Feem ntau yog tsim los ntawm ntau tshaj 90% alumina (Al2O3), kom ntseeg tau zoo heev refractory zog.

2. ** Siab kub ua haujlwm: **Muaj peev xwm tiv taus qhov kub thiab txias txog li 1900 ° C, ua rau lawv haum rau qhov xav tau tshaj plaws ntawm qhov kub thiab txias.

3. ** Mechanical Strength: **Corundum bricks muaj lub zog siab compressive thiab hnav tsis kam, ua rau lawv tuaj yeem ua haujlwm hnyav thiab ua haujlwm hnyav.

4. ** Corrosion Resistance: **Lawv tiv thaiv corrosion los ntawm slags, acids, alkalis, thiab lwm yam tshuaj, ncua lawv lifespan nyob rau hauv hnyav ib puag ncig.

5. ** Tsawg Porosity: **Tsawg porosity pab tiv thaiv cov infiltration ntawm cov ntaub ntawv molten thiab gases, txhim kho durability thiab thermal rwb thaiv tsev zog.

6. ** Thermal Stability: **Lawv pom zoo thermal stability thiab tsis kam mus rau thermal poob siab, uas yog ib qho tseem ceeb rau cov txheej txheem cuam tshuam nrog ceev kub hloov.

7. ** Dimensional Stability: **Cov ntsiab lus alumina siab ua kom cov cib tuav lawv cov duab thiab ntim ntawm qhov kub thiab txias, tiv thaiv kev ua haujlwm tsis zoo.

Cov yam ntxwv no ua rau corundum cib zoo tagnrho rau siv nyob rau hauv ntau yam kev siv kub, nrog rau cov cua kub cua sov, qhov cub kub kub, steel ladles, thiab lwm yam muaj cua sov thiab kilns.
