Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the examples.

[0023] The invention discloses a control method for automatic ladle casting of a continuous casting machine. The opening control principle of the sliding nozzle is the same as the closing control principle, that is, it is opened or closed for a fixed time, and then the next opening or closing action is performed until the sliding nozzle is satisfied. The sliding nozzle closing or opening condition; then the sliding nozzle is closed or opened for a fixed time, and then the next closing or opening action is performed until the sliding nozzle opening or closing condition is met, and so on.

[0024] The specific process is:

[0025] S1. According to the size of the tundish’s own capacity, when the net weight of the tundish reaches a certain weight, press the automatic casting button of the large ladle sliding nozzle. At this time, the automatic pouring of the large ladle slid...

Abstract

The invention relates to a control method for automatic ladle casting of a continuous casting machine. The control process is as follows: the opening control principle of the sliding nozzle is the same as the closing control principle, that is, it is opened or closed for a fixed time first, and then the next opening or closing action is performed. , until the closing or opening condition of the sliding gate is satisfied; then the sliding gate is closed or opened for a fixed time, and then the next closing or opening action is performed until the opening or closing condition of the sliding gate is met, and so on. The method can realize the automatic control of the ladle sliding nozzle of the continuous casting machine, maintain the stability of the tundish liquid level, solve the problem of large fluctuations in the tundish liquid level when the sliding nozzle is manually operated, and effectively reduce labor costs at the same time.

Description

technical field [0001] This patent application belongs to the technical field of automatic casting control, and more specifically relates to a control method for automatic casting of large ladles in continuous casting machines. Background technique [0002] Continuous casting, that is, continuous casting of steel, compared with the traditional die casting method, continuous casting technology has significant advantages such as greatly increasing the metal yield and saving energy. [0003] The process flow of continuous casting is as follows: the ladle molten steel is injected into the tundish through the ladle nozzle, and then the tundish distributes the molten steel to each crystallizer through the ladle nozzle. Under the joint action of slag lubrication, tension leveler and crystallization vibration device, the cast slab in the mold is pulled out, and the cast slab is forced and uniformly cooled within the length interval from the mold outlet to the tension leveler, that i...
