Problems solved by technology

[0009] Practice has proved that using an external electromagnetic field to promote the molten steel in the tundish to obtain a swirling flow field can indeed play a significant role in improving the quality of molten steel, but it significantly increases equipment investment and operating costs, which is not conducive to the widespread use in continuous casting production in steel mills.

Embodiment 1

[0038] key size

[0039] The tundish is used for experimental research, at a flow rate of 1.5-3.5m 3 Under the condition of / h, the rotation speed of molten steel is 10-100rpm. Through numerical simulation and experimental determination, it can be judged that the tundish has good functions of controlling flow and removing inclusions.

Embodiment 2

[0041]

[0042] The tundish is used for steelmaking and continuous casting production, at a flow rate of 15-35m 3 Under the condition of / h, the obtained rotational speed is 5~60rpm. The use of this tundish is expected to reduce inclusions by 10%, thus playing a good function of removing inclusions.

Embodiment 3

[0044] key size

[0045] Using the molten steel spin-type continuous casting tundish of this embodiment, at a flow rate of 1.5 to 3.5m 3 Under the condition of / h, the rotation speed of molten steel is 10-100rpm. Through numerical simulation and experimental determination, it can be judged that the tundish has good functions of controlling flow and removing inclusions.

Abstract

A molten steel spinning type conticasting tundish able to effectively separate non-metal impurities and prevent secondary oxidizing and slag collection is composed of main body, long sprue, retaining wall, retaining dam, immersible sprue, cyclone chamber and circular tangent inlet of molten steel.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to an intermediate device in steelmaking and continuous casting production. Background technique [0002] The tundish is a kind of intermediate equipment required in the production process of steelmaking and continuous casting, and it is the connection point from batch operation to continuous operation in steelmaking production. It is one of the important equipment to improve steel output, quality and production efficiency. [0003] In the 1950s, continuous casting technology developed as a landmark achievement in the iron and steel industry, which is characterized by fast process speed and concentrated investment. In 1970, the continuous casting ratio in the world was only 5.6%, but by 1990, the continuous casting ratio in the world had reached 62.4%, and the continuous casting ratio in some developed countries exceeded 95%. In 1994, the continuous casting ratio in the world w...
