A control system and control method for an aluminum ingot casting device

Abstract

The invention relates to the field of control over an aluminum ingot casting device, in particular to a control system and method of the aluminum ingot casting device. A sensor and a limiting switch for metering are respectively arranged under a molten aluminum distributor and a casting bag, a casting disc is provided with a stopping limiting switch, and each casting mould is provided with a limiting plate. The sensor is arranged under the distributor, the distributor is installed on a distributor rotary center, the distributor rotary center is connected with a driving device, and a PLC is respectively connected with a left disc control system, a right disc control system, the sensor of the distributor, a limiting switch of the distributor and an executive component of the distributor, is used for receiving the signals input by each switch, and sends control commands to each executive component. When yield needs to be increased, another casting disc is started. By means of the control system and method of the aluminum ingot casting device, the stopping position of the casting mould is accurate, casting is carried out conveniently, the weights of all the aluminum ingot are the same, the labor intensity for operating staff is relieved, working efficiency is improved, and operation and the system are safer and more reliable.

Description

technical field [0001] The invention relates to the control field of aluminum ingot casting devices, in particular to a control system and a control method for producing large aluminum ingot casting devices. Background technique [0002] In recent years, my country's electrolytic aluminum industry has developed very rapidly and has become the world's largest producer of primary aluminum. The 400kA large prebaked electrolytic cell has become the main cell type of my country's electrolytic aluminum industry, and the 500kA large prebaked electrolytic cell has been successfully developed. The matching molten aluminum casting production line is also required to meet the needs of large-scale production. Due to the low production capacity of casting small aluminum ingots, the consumption of primary aluminum is higher than that of large aluminum ingots; small aluminum ingots need to be packaged during transportation, which takes up a lot of space and high cost, so it is imperative to...

Due to the low production capacity of casting small aluminum ingots, the consumption of primary aluminum is higher than that of large aluminum ingots; small aluminum ingots need to be packaged during transportation, which takes up a lot of space and high cost, so it is imperative to study large aluminum ingot casting production lines

Most of the casting machines for large aluminum ingots adopt a disc structure. During casting, it is necessary to stop at each casting mold position for casting. When the casting machine has 20 casting molds, the disc needs to be stopped once every 18° rotation. Due to processing and installation errors, it is difficult Ensure that each mold is on the 18° index line, which affects the casting process
