A flow control device for the front box of a gate-type magnesium alloy casting and rolling mill

Abstract

The invention provides a flow control device for the front box of a gate-type magnesium alloy casting and rolling machine, which belongs to the field of magnesium alloy casting and rolling, and mainly includes a transmission device, a transmission locking mechanism, a detachable gate flow control valve and a sealing device; the transmission device and the detachable gate The gate of the flow control valve is connected to drive the gate to move up and down. The transmission device is connected in series with the transmission locking mechanism and placed on the outer surface of the front box. The sealing device is set on the gate connecting rod of the detachable gate flow control valve; through the transmission device Pull the gate to slide up and down, and the transmission locking mechanism is connected in series with the transmission device to ensure accurate control of the flow at the valve port. The improved detachable gate flow control valve solves the stuck problem after the valve is thermally deformed, and is easy to replace, reducing the The labor intensity of the workers improves the production efficiency, and the overall structure of the flow control device provides a good way for a simple, safe and reliable sealing method. The present invention has outstanding advantages in flow control precision and integral sealing performance of the structure under high temperature environment.

Description

technical field [0001] The invention relates to the field of magnesium alloy casting and rolling, in particular to a flow control device for a front box of a gate-type magnesium alloy casting and rolling machine. Background technique [0002] High-performance wrought magnesium alloy sheets are urgently needed basic materials in industries such as aviation, aerospace, automobiles, high-speed rail, and 3C electronic products, and are the future development direction of magnesium alloys. However, the domestic production process and technology are still immature, and the magnesium alloy sheet is still heavily dependent on imports from Japan, Europe and the United States and other countries. However, the preparation of magnesium alloy sheet urgently needs the support of relevant advanced forming process theory and equipment technology. With the advantages of high yield and low cost, it has become an advanced preparation technology with the most potential and application prospect...
