In recent years, the global high-temperature industry has been developing towards high-efficiency energy saving, green environmental protection and material upgrading, and traditional materials are facing performance bottlenecks. Chrome corundum, as a high-performance material that combines the hardness of corundum with the chemical stability of chromium oxide, is gradually becoming a new favorite in the field of refractory materials and abrasives.

1. Performance advantages of chrome corundum

Chrome corundum is a composite refractory material made of high-purity aluminum oxide as the matrix, adding an appropriate amount of chromium oxide, melting in an electric arc furnace and then cooling. It has the following characteristics:

High hardness and good impact resistance: suitable for high-intensity grinding and sandblasting operations

Excellent thermal shock stability: maintain structural stability in high-temperature working conditions with frequent alternation of hot and cold

Excellent corrosion resistance: resistant to acid and alkali erosion, especially suitable for the chemical industry

Stable chemical properties: performs well in strong reducing or oxidizing atmospheres

2. Main application areas Domain

Currently, chrome corundum is widely used in the following industries:

Metallurgical furnace lining and slide bricks: extend the service life of the furnace body and reduce the maintenance frequency

Precision grinding tools and grinding wheels: used for efficient grinding of hard materials such as stainless steel and alloy steel

Ceramic kiln tools and heat treatment furnace structures: high temperature resistance and cracking resistance

Sandblasting and surface treatment media: suitable for aerospace, military industry, molds and other fields

3. International market demand trend

In Europe, the United States and Southeast Asian countries, due to the rising demand for industrial automation and high-end manufacturing, the import proportion of high-performance refractory materials has increased year by year. According to industry data:

The European market prefers chrome corundum with uniform particle size and stable color for industrial abrasives

Southeast Asia and the Middle East are more concerned about its thermal shock resistance in high-temperature kilns

North American manufacturers are concerned about its environmental protection attributes and reusability

With the global implementation of green manufacturing standards, chrome corundum is expected to become one of the key promotion materials in the next stage due to its controllable emissions and long life characteristics.
