Stopper device for magnesium alloy continuous casting stove

Abstract

The invention provides a stopper rod device for a magnesium alloy continuous casting furnace. The device comprises a graphite base and a graphite end, wherein the graphite end is connected with a stopper rod, the stopper rod is inserted in a crucible cover of the continuous casting furnace and a furnace cover of a furnace shell of the continuous casting furnace, and the other end of the stopper rod is connected with a cylinder controlled by a pneumatic controller; the stopper rod device is characterized in that the graphite base is a little higher than a magnesium fluid channel inlet on the bottom part of the crucible, and is bucket-shaped, the lower end of the graphite end is taper-shaped; the stopper rod device for the magnesium alloy continuous casting furnace can input technological parameters of the continuous casting furnace into the pneumatic controller to realize the control of the up-and-down movement of the cylinder, and makes, by the descent and ascent of the stopper rod, the graphite end leaves and get close to the graphite base to allow and block the magnesium fluid to flow in the fluid channel, thereby realizing the current limitation of the magnesium fluid; moreover, the device has the characteristics of automatic control, safety and effectiveness.

Description

Technical field [0001] The invention relates to an equipment in the technical field of alloys, in particular to a stopper rod device for a magnesium alloy continuous casting furnace. Background technique [0002] Continuous casting technology is a casting process that can realize continuous production of ingots, which can not only improve product quality, but also increase production efficiency. Because it is a continuous operation, it is necessary to consider that once a problem occurs in the continuous operation, the operation needs to be interrupted and a pre-plan or measure should be proposed. At present, in the metallurgical industry, there is no effective device for controlling the flow of high-temperature metal melt. The method of blocking the outlet is basically adopted, which is not effective enough. If it cannot be implemented when a large amount of melt leakage occurs, the cooling melt channel is generally used, and the solidified melt achieves the purpose of controll...
