Tundish Board for Continuous Casting Manufacturers

A tundish board, also known as a tundish cover or tundish refractory board, is a crucial component in the continuous casting process of molten metal, primarily used in steel production. This board is typically made from a refractory material, such as ceramic fiber, which can withstand the high temperatures and harsh conditions of the casting environment.

The tundish board is positioned on top of the tundish, a vessel that holds the molten metal before it is poured into the casting mold.The main purpose of the tundish board is to regulate the flow of molten metal from the tundish into the mold.

High-quality refractory raw materials are chosen for the tundish board manufacturing process. These materials often include ceramic fibers, binders, fillers, and additives that contribute to the board’s thermal stability, mechanical strength, and resistance to thermal shock.

The formulated mixture is shaped into the desired dimensions of the tundish board. This can be done using various techniques, such as casting, pressing, extrusion, or vacuum forming. The shaping process ensures that the refractory material is evenly distributed and compacted to create a uniform structure.

The dried tundish boards are fired in kilns at high temperatures. The firing process, also known as sintering, involves heating the boards to temperatures that cause the raw materials to chemically react and form a solid, coherent structure. This process enhances the mechanical strength and thermal stability of the boards.
