What is a blast furnace ceramic cup?

Blast furnace ceramic cup is a special ceramic container used in the blast furnace smelting process. It is usually made of heat-resistant and corrosion-resistant ceramic materials and has good high temperature resistance and chemical stability. Blast furnace ceramic cups are mainly used to collect waste materials such as slag and metal decarburization at the blast furnace outlet.

The blast furnace ceramic cup is usually located under the taphole of the blast furnace, which is called the hearth. It is similar to the shape of a large bowl or cup, with a larger diameter and a slightly raised bottom to facilitate the collection of slag and metal decarburization materials. During the operation of the blast furnace, slag and metal decarburization materials will flow into the ceramic cup through the tap hole, and will be processed and recycled through pipes or conveyor belts.

The main features of blast furnace ceramic cups include high temperature resistance, corrosion resistance and wear resistance. It needs to be able to withstand the impact and erosion of high-temperature gases and slag during blast furnace operation, and maintain structural integrity and stability during repeated use and cleaning.

The use and maintenance of blast furnace ceramic cups require compliance with relevant operating procedures and safety measures. Regularly check and maintain the structural integrity of the ceramic cup, the protective coating on the inner surface, the fastening and sealing of the joints, etc., and carry out cleaning, drying and repair according to the actual situation to ensure the normal operation and extension of the blast furnace ceramic cup service life.
