Abstract

The invention discloses a vertical semi-solid state cast rolling device and method and relates to aluminum alloy cast rolling equipment and the technical field of manufacturing in order to solve the technical problems that an existing cast rolling method is low in production efficiency, a casting nozzle is prone to blockage, and serious macro segregation and micro segregation defects exist. The vertical semi-solid state cast rolling device comprises a platform, and a launder is arranged at the upper end of the platform; the lower end of the platform is provided with a casting nozzle which is communicated with the launder; the outlet position of the casting nozzle is horizontally and symmetrically provided with a left cast rolling roller and a right cast rolling roller; an outlet of the casting nozzle is higher than a center line of the left cast rolling roller and the right cast rolling roller; a flow dividing block is arranged in the casting nozzle in the width direction; and cooling water is introduced in a roller sleeve of the left cast rolling roller and a roller sleeve of the right cast rolling roller.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting and rolling equipment and manufacturing, in particular to a vertical semi-solid casting and rolling device and a casting and rolling method. Background technique [0002] At present, the feeding methods of high-quality aluminum alloy plates and strips for industrial use mainly include direct cooling casting, casting and rolling, and continuous casting and rolling. Among them, the process of the direct cooling casting method mainly includes: semi-continuous ingot casting, head cutting, face milling, heating, hot rolling, intermediate annealing, cold rolling, heat treatment, etc. There are many production processes, and multiple heatings lead to high energy consumption. The cycle is long, the efficiency is low, and the equipment investment is large; Intermediate annealing and other processes, a processing technology in which liquid metal is directly poured into the gap between two ro...
