Problems solved by technology

[0004] Although the above-mentioned device can reduce the nitrogen absorption of molten steel in the tundish and reduce the non-metallic inclusions flowing into the mold, it is difficult to salvage the impurities in the face of the presence of non-metallic inclusions in the tundish, causing the impurities to be damaged. The impact of molten steel is b

Abstract

The invention provides a steel pouring tundish which comprises a tundish body. A lining, a submerged nozzle, a stopper rod, an impact groove, a long nozzle, a lifting mechanism, a retaining dam, a retaining wall and a tundish cover are arranged on the tundish body, wherein the lining is arranged on the inner surface of the tundish body; the tundish cover is movably installed at the upper end of the tundish body; the submerged nozzle is arranged in the middle of one side of the outer surface of the lower end of the tundish body, and the stopper rod penetrates into the submerged nozzle, and penetrates into the tundish body from one side of the outer surface of the upper end of the tundish cover, and the impact groove is formed in the middle of the other side of the inner surface of the lowerend of the tundish body; and the long nozzle penetrates into the tundish body from one side of the outer surface of the upper end of the tundish cover. According to the steel pouring tundish, floating non-metal impurities can be fished, and the cleanliness of molten steel is improved; the steel pouring tundish facilitates removal of fished impurities, and removal of air in the tundish is faciliated; the impact resistance of the tundish to the molten steel is improved; and the service life of the tundish is prolonged.

Description

technical field [0001] The invention relates to the technical field of iron and steel pouring, in particular to a steel pouring tundish. Background technique [0002] The tundish is a refractory container used in short-process steelmaking. It first receives the molten steel poured from the ladle, and then distributes it to each crystallizer from the tundish nozzle. As an important basic raw material, steel is widely used in the world play a pivotal role in the economic development of various countries; [0003] Chinese patent discloses a new type of continuous casting tundish, the patent application number is CN201020567353.7, which includes a tundish container, a liquid inlet pipe placed on the top surface of the tundish container and an outflow pipe arranged at the other end of the bottom of the tundish container. The tundish container also includes a bubble generator arranged between the outlet pipe and the liquid inlet pipe, and the bubbles generated by the bubble gener...
