By means of the testing device for simulating the flow field in the continuous casting crystallizer, the liquid level of the crystallizer model can be accurately controlled, and the width of an inner cavity of the crystallizer model and the taper of an inner billet shell of the crystallizer model can be adjusted.

Description

technical field [0001] The invention relates to the field of slab continuous casting, in particular to a test device for simulating the flow field of a continuous casting crystallizer. Background technique [0002] The continuous casting mold is the most important part of the continuous casting process, known as the "heart" of the continuous casting equipment. The molten steel in the tundish is injected into the mold through the submerged nozzle, and cooled in the mold to form a billet with a certain shell thickness. The solidification of the molten steel in the mold includes heat transfer, mass transfer, phase change, and multiphase flow. etc., is a complex dynamic process. The flow field in the mold is very important to the final quality of the slab, but the flow field in the mold cannot be measured in actual production. Therefore, the flow field in the mold can be studied by using the mold water simulation system, which can be simulated and displayed Liquid flow state i...

Problems solved by technology

The flow field in the mold is very important to the final quality of the slab, but the flow field in the mold cannot be measured in actual production. Therefore, the flow field in the mold can be studied by using the mold water simulation system, which can be simulated and displayed Liquid flow state in the crystallizer

[0003] The control of the crystallizer liquid level in the traditional crystallizer water simulation system is realized by adjusting the inlet flow and outlet flow of the crystallizer. The width of the inner cavity cannot be adjusted online, nor can it simulate the process parameters such as the taper of the billet shell in the mold and the thickness of the solidified layer of the cast billet
