Abstract

The invention relates to a crystallizer model for flow field research in a crystallizer and a crystallizer flow field simulation method, and belongs to the technical field of continuous steel casting.The crystallizer model for flow field research in the crystallizer provided by the invention comprises a crystallizer body, wherein an immersion type nozzle is formed in the top of the crystallizer body; the immersion type nozzle is connected with a water inlet pipe; a water outlet is formed in the bottom of the crystallizer body; a flow distributor is arranged inside the crystallizer body. According to the invention, the flow distributor is added to the crystallizer model to avoid influence of vortex generated at an outlet of the model on a flow field in the crystallizer, so that the flow field in the crystallizer is more accurate. Then, a finite element software package ANSYS is adopted to establish a molten steel flow model in the crystallizer for simulating the flow field of molten steel in the crystallizer under various process conditions; water simulation experiment results are verified and compared; finally, the water simulation experiment results and numerical calculation results are combined with an actual site to perform optimized design on process operation parameters.

Description

technical field

[0001] The invention relates to a mold model and a mold flow field simulation method for the study of the flow field in the mold considering the eddy current behavior, which is mainly used in the research of the flow field in the mold and the optimization of process operation parameters in the field of continuous steel casting technology. It is suitable for continuous casting of billets, slabs, round billets and all other types, especially in the field of continuous casting of ultra-thin special-shaped billets. Background technique

[0002] The continuous casting process is the solidification and forming process of liquid metal including complex phenomena such as flow, mass transfer and heat transfer. Especially for the mold section of the continuous casting machine, the flow, mass transfer and heat transfer processes interact and affect each other. Research is very difficult, almost impossible. If the flow field in the mold is not properly controlled, the s...
