Embodiment Construction
[0021] Taking quantitative casting control of copper anode plates as an example, the control process and beneficial technical effects of the present invention will be further described in conjunction with the accompanying drawings.
[0022] Before starting automatic quantitative casting, set the weight of the copper anode plate to be cast and the error amount of the anode plate.
[0023] set up figure 1 The pre-start voltage 1, the start voltage 2, the copper output voltage 3, the acceleration voltage 4, the buffer voltage 5, the constant speed voltage 6, the deceleration voltage 7, and the package voltage 8. After the casting starts, the casting ladle proportional valve drives the hydraulic cylinder according to the voltage at each stage, and at the same time the system detects the signal of the casting scale sensor, calculates the signal and automatically compares it with the set casting mathematical model, eliminating the interference of the casting ladle movement on the we...

The invention discloses a method for controlling the constant casting of an anode plate of a melt, which comprises the following steps that: the acquired weighing signals are analyzed by matching a preset casting control curve with a casting scale; after the obtained analysis results are calculated by a PLC program, voltages are output to the action of each stage of casting weighing so as to control the precise action of a proportional valve of a hydraulic cylinder of a ladle to carry out constant casting, wherein the output voltages comprise twelve stages: pre-starting voltage, starting voltage, copper-venting voltage, accelerating voltage, buffer voltage, uniform voltage, decelerating voltage, ladle-control voltage, copper-venting transient voltage, accelerating transient voltage, uniform transient voltage and decelerating transient voltage, the copper-venting transient voltage curve, the uniform transient voltage curve and the decelerating transient voltage curve refer to an exponential function y = ax; the accelerating transient voltage curve and an automatic adjusting voltage curve refer to a logarithmic function y = loga<X>, after the casting scale operates to this section along the curve, an instant voltage taken by the PLC and a preset voltage are performed weighted average so as to calculate the value of y as the output voltage, then the proportional valve is driven to accurately vent the melt. The invention efficiently solves the problem of large error existing in the casting of the anode plate of the melt.
Description
technical field [0001] The invention relates to a method for controlling quantitative casting of molten anode plates in the field of metallurgy. Background technique [0002] Copper fire refining is an important process in the copper production process. It needs to be equipped with a casting disc to cast the refined copper water into an anode plate for the electrolysis process. The casting process of existing domestic reverberatory furnaces mostly adopts the manual casting method in which the depth of the copper mold is equal to the thickness of the anode. The weight of the anode plate is completely controlled manually. The status has a direct relationship, and the scrap rate of the anode plate is higher. The purpose of this technology is to improve the degree of equipment automation and operational reliability, reduce the number of operating workers, reduce labor intensity and labor costs, effectively improve work efficiency, and improve the pass rate of anode plate castin...
