About Tundish Boards
Tundish Boards are pre formed silica based refractory panels used as the inner working lining of a tundish during continuous casting of steel. A tundish is the intermediate vessel that holds molten steel before it flows into the moulds. Since molten steel reaches temperatures above 1500°C, the inner surface of the tundish must be capable of withstanding extreme heat, slag attack, and metal erosion. Tundish boards protect the permanent lining and improve the speed in steel plants.

What Are Tundish Boards?
Tundish boards are lightweight refractory boards installed on the side walls and bottom surface of a tundish. They form the working lining, meaning they are in direct contact with molten steel and slag during casting. These boards are replaced after every casting campaign, protecting the main structure of the tundish from damage. Unlike the traditional brick or castable linings, tundish boards are ready made and easy to install. This reduces installation time, simplifies maintenance, and improves turnaround time between casting operations.
Role of Tundish Boards in Continuous Casting?
During continuous casting, molten steel creates high thermal and mechanical stress inside the tundish. = Tundish boards act as a protective barrier between the molten metal and the permanent lining. Traditional brick or castable linings require long and controlled heating to remove moisture; they cannot be immediately heated because this will create steam and may lead to cracking. Tundish boards are manufactured in pre dried condition, allowing faster heating and reduced preparation time. They are light weight and low in free moisture so, tundish boards help avoid lengthy preheating cycles This shorter preheating process results in significant energy savings and improved operational efficiency in steel plants. A major advantage is easier de-skulling. De-skulling is the removal of solidified slag and metal deposits known as skulls formed inside the tundish after casting. When molten metal penetrates joints or lining materials, it becomes difficult to remove. Properly designed tundish boards limit penetration and allow easier removal of deposits, reducing maintenance time and improving turnaround between casting operations.
