Light alloy cast-rolling flow distribution device

Abstract

The invention discloses a light alloy cast-rolling flow distribution device, and belongs to the field of light alloy casting. The defects that the shape of a flow distribution block widely adopted ina metal melt flow distribution system in an existing cast-rolling process greatly influences melt flow, so that melt distribution in a cavity is not uniform, most melts are in a turbulent flow state,air holes are extremely prone to occurring in the cast-rolling process, and casting performance is severely influenced are overcome. Symmetrical slotted holes are formed in the two sides of a metal melt groove, when the liquid level of a melt reaches the slotted holes in the two sides of the metal melt groove, the metal melt flows out of the inclined slotted holes in the two sides of the metal melt groove at the same time and is evenly poured on the surface of a left roller and the surface of a right roller, and symmetrical cast rolling is achieved. In addition, the rising speed of a metal melt supporting plate guide column fixing connecting plate is accurately controlled by a motor, and therefore the influence of speed fluctuation on the quality of cast-rolled pieces can be effectively prevented. The device is simple in structure, uniform distribution of liquid flow can be effectively achieved, and the turbulence phenomenon can be reduced 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. Background technique [0002] At present, the main development direction of the metal processing field at home and abroad is low energy consumption, low cost, high efficiency and short process. Due to the remarkable characteristics of high specific strength and specific stiffness, light metal materials have broad prospects in the fields of automobiles, rail transit, and aerospace.

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
