Chrome Corundum Castable

Chromium-corundum castable refractory belongs to the composite corundum castable series. It is formulated using high-strength refractory raw materials such as corundum and chromium oxide as aggregates and fine powders, combined with micro-powders, binders, and additives. This material can be formed by casting. During construction, the binder, setting accelerator, and an appropriate amount of water are added and mixed to obtain a mixture with good fluidity. The ratio of aggregates, powders, and binders can be adjusted as needed. Commonly used binders include pure calcium aluminate cement, phosphoric acid, or aluminum dihydrogen phosphate.

一.Physical And Chemical Indicators of Chrome Corundum Castable

二.Chromium corundum castable is a high-temperature refractory material with the following characteristics:

1. High-temperature stability: Chromium corundum castable can withstand extremely high temperatures without softening or melting, maintaining stable physical and chemical properties.

2. Wear resistance: Chromium corundum castable resists wear, abrasive impact, and abrasive erosion, making it suitable for harsh working environments with severe wear.

3. Corrosion resistance: It resists corrosion from acids, alkalis, and other corrosive media, allowing for long-term use in corrosive environments without damage.

4. High strength: It can withstand heavy loads and impacts without cracking or deformation.

5. Low thermal expansion coefficient: Chromium corundum castable has a low thermal expansion coefficient, reducing thermal stress caused by temperature changes and extending the service life of the refractory material.

6. Good thermal conductivity: It has high thermal conductivity, allowing for rapid heat transfer and maintaining a stable temperature on the castable surface, preventing thermal stress and thermal shock.

7. Easy processability: It can be molded as needed, facilitating pouring and installation.

8. Slag resistance: Chromium corundum castable effectively resists erosion from molten slag and molten metal, preventing slagging and condensation, and maintaining the stable performance of the castable.

三.The characteristics of chromium corundum castable make it widely used in high-temperature industrial fields, such as iron and steel metallurgy, refractory material manufacturing, power generation, and chemical industries. It can be used as the lining and insulation layer for high-temperature equipment such as blast furnaces, steelmaking furnaces, electric furnaces, converters, and glass kilns, effectively improving equipment service life and production efficiency.
