Continuous casting steel ladle no-drainage casting device

Abstract

The invention relates to a continuous casting steel ladle no-drainage casting device. The continuous casting steel ladle no-drainage casting device comprises an upper water port mechanism and a lower water port mechanism; the upper water port mechanism is fixed at the bottom of a steel ladle, and has an upper water port connected with the steel ladle; the lower water port mechanism is correspondingly arranged below the upper water port mechanism; the lower water port mechanism has a lower water port and an argon blowing port; and the lower water port mechanism can transversely move corresponding to the upper water port mechanism to realize alternative communication between the lower water port or the argon blowing port and the upper water port. The continuous casting steel ladle no-drainage casting device facilitates increment of the self-open rate of continuous casting ladles, wherein a novel argon blowing slide plate for continuous casting steel ladles can realize a no-drainage sand casting process, so that the secondary pollution of molten steel is reduced.

Description

technical field [0001] The invention relates to a pouring device for a ladle, in particular to a pouring device for a continuous casting ladle without drainage. Background technique [0002] With the rapid development of my country's economy, industries such as automobiles, petroleum, and machinery manufacturing have higher and higher requirements for steel materials. How to smelt ultra-pure steel is a process of continuous innovation. At present, the continuous casting production mainly adopts the ladle plus drainage sand drainage and pouring process. When the ladle is continuously cast, the drainage sand will enter the tundish, which will pollute the quality of molten steel to a certain extent. [0003] Oxygen burning operation is required when the ladle is not self-opening. Oxygen burning seriously affects the quality of molten steel and increases the workload of continuous casting operators, and the quality of drainage sand is an important factor affecting the self-openi...

At present, the continuous casting production mainly adopts the ladle plus drainage sand drainage and pouring process. When the ladle is continuous casting, the drainage sand will enter the tundish, which will pollute the quality of molten steel to a certain extent.

[0003] Oxygen burning operation is required when the ladle is not self-opening. Oxygen burning seriously affects the quality of molten steel and increases the workload of continuous casting operators, and the quality of drainage sand is an important factor affecting the self-opening rate of continuous casting ladles. One, how to ensure the quality of continuous casting molten steel, avoid secondary pollution as much as possible and improve the self-opening rate of continuous casting ladles are difficult problems for metallurgical workers
