Flow distribution device for light alloy casting and rolling

Abstract

The invention discloses a flow distribution device for light alloy casting and rolling, which belongs to the field of light alloy casting. Aiming at the shunt block widely used in the current distribution system of metal melt in the existing casting and rolling process, its shape has a great influence on the flow of the melt. As a result, the melt distribution in the cavity is uneven, and the melt is mostly in a turbulent state. Defects such as pores are prone to occur during the casting and rolling process, which seriously affects the performance of the casting. Both sides of the molten metal tank in the present invention are provided with symmetrical slot holes, and when the melt liquid level reaches the positions of the slot holes on both sides of the molten metal tank, the molten metal will be inclined from both sides of the molten metal tank. The holes flow out at the same time and are evenly distributed on the surfaces of the left roll and the right roll respectively to realize symmetrical casting and rolling. In addition, the rising speed of the metal melt supporting plate guide column fixed connecting plate is precisely controlled by the motor, which can effectively prevent the influence of speed fluctuation on the quality of cast and rolled parts. The device has a simple structure, can effectively realize uniform distribution of liquid flow, and can reduce turbulent flow as much as possible.

Description

technical field [0001] The invention belongs to the field of light alloy casting, and in particular relates to a flow distribution device for light alloy casting and rolling.

Problems solved by technology

Although the diverter block widely used in the existing flow distribution system can improve the flow of the molten metal in the cavity, the flow behavior of the melt is greatly affected by the shape of the diverter block, resulting in uneven distribution of the molten metal in the cavity It still exists, and affected by the shunt block, the melt mostly presents a turbulent flow state, and defects such as pores are prone to appear during the casting and rolling process, which seriously affects the performance of the casting
