Q & A

Refractory materials perform crucial roles in ladles and tundishes by providing high temperature resistance, thermal insulation, and chemical stability. They withstand extreme temperatures and harsh conditions, protecting the ladles and tundishes from erosion, corrosion, and thermal shock. Additionally, refractory materials help maintain consistent temperature distribution, prevent heat loss, and ensure the quality of molten metal during the casting process.

Refractory materials resist the attack of molten slags due to their high melting points, chemical inertness, and ability to form a protective layer or slag film on their surface. This protective layer acts as a barrier, preventing the molten slag from penetrating and eroding the refractory material. Additionally, their dense and non-porous structure helps to minimize the infiltration of molten slag, thus enhancing their resistance against slag attack.

There are several types of refractory coatings that are used for corrosion resistance. Some common types include ceramic coatings, polymer coatings, metallic coatings, and composite coatings. Ceramic coatings, such as alumina or zirconia, provide excellent resistance to high temperatures and corrosive environments. Polymer coatings, such as epoxy or polyurethane, offer good chemical resistance and can be easily applied. Metallic coatings, such as zinc or aluminum, provide sacrificial protection by corroding in place of the underlying substrate. Composite coatings combine different materials to create a coating with enhanced corrosion resistance properties. Each type of coating has its own advantages and is chosen based on the specific application requirements and conditions.
