Description

Integral tundish impact area prefabricated part

Technical Field

The utility model relates to a ferrous metallurgy equipment field especially relates to an integral tundish impact area prefab.

Background

The tundish is a refractory material container between the continuous casting ladle and the crystallizer, is a continuous metallurgical reactor and can further purify molten steel. Before molten steel enters the crystallizer through the tundish, nonmetallic inclusions in the molten steel must be removed in the tundish in a floating mode. In order to produce high-purity steel, measures such as barricading, dam adding, argon blowing, ceramic filter and the like are adopted in the tundish, so that non-metal inclusions in the steel can be greatly reduced.

The existing impact area is formed by splicing and installing a slag wall, an impact plate and a guard plate in a tundish by adopting daub or coating, and the existing impact area has the following defects: 1, in the installation process, the hoisting and splicing processes increase the labor intensity of operators; 2, because of the cement or the coating material joints between the slag-stopping wall and the protective plate and between the protective plate and the protective plate, in the using process, the joints are easy to crack, shift hidden troubles and safety risks.
