Automatic flow control system for stationary type foundry furnace

Abstract

The invention provides an automatic flow control system for a stationary type foundry furnace. The system comprises rotary installation frame fixedly installed on the side wall of a furnace body, a sliding table device installed on the installation frame and driven by a motor, a traction arm connected with the sliding table device, a drill bit assembly which is fixed to the traction arm through alock catch, a detection device arranged on the installation frame and an electrical control system used for electrically controlling the detection device and the sliding table device. The complete high-precision closed-ring control system is formed, high-precision automatic flow control requirements are met, the control precision within the range of -1.5mm-1.5mm of th stationary furnace drainage flow groove liquid surface can be achieved, cast aluminum melt can be stably rotated through a flow groove, the slagging and oxidation air suction phenomena in the foundry process can be reduced, the high-quality foundry technology can be achieved in a matched mode, the highly-integrated device is achieved, installation is easy and convenient, manual and automatic operation is achieved, and the practical function is quite high.

Description

technical field [0001] The invention relates to the technical field of aluminum casting production equipment, in particular to an automatic flow control system for a stationary casting furnace. Background technique [0002] In the casting production process of the aluminum processing industry, various types of fixed holding furnaces are widely used for casting production. During the production process, the melt in the furnace flows out from the flow hole at the bottom of the furnace under the action of gravity, and its flow rate and flow rate are affected by the furnace. The influence of the inner melt depth is always changing. In order to achieve stable casting production, it is necessary to use the drill bit assembly and the flow eye to control the casting liquid level. [0003] At present, the drill bit components for flow control in the fixed furnace are basically controlled manually, which requires the operator to continuously adjust the position of the drill bit compon...

AI Technical Summary

Problems solved by technology

[0003] At present, the drill bit assembly for flow control of the fixed furnace is basically manually controlled, requiring the operator to continuously adjust the position of the drill bit assembly. The labor intensity is high, and the discharge control accuracy is poor, which will cause fluctuations in the level of the casting liquid, which will affect the casting process and the final product quality. Both bring adverse effects. Although the tilting casting furnace can solve the problem of casting liquid level fluctuations, the tilting casting furnace has a huge investment and is not suitable for the production process requirements of all alloy products. Therefore, the fixed furnace casting furnace is still the current choice. Aluminum Alloy Mainstream Casting Production Furnace

[0004] In the past few years, various types of automatic flow control devices have been studied in the industry, but generally speaking, they are all simple drill bit assembly controls, and the research on complex working conditions is insufficient, and the operation convenience is not enough. Therefore, they have not been obtained. Promote application
