Constant Flow Automatic Pouring Control System Research And Design

Research and design a suit of servomechanism to realize accurate flux control is the key to resolve blight from technics parameter to the electromagnetic fast casting-rolling of aluminum strips. In this paper, some key technologies of the servomechanism are researched detailedly such as the flux model, the circuit construction, the computer control and so on.At first, the paper introduces the mode and actuality of molten aluminum's inpouring in the electromagnetic fast casting-rolling of aluminum strips, and the influence of flux to beaten aluminum is expounded. Analyzing the framework and working principle of inpouring system clears up the research direction and design approach. The flux model of the inpouring is founded firstly to find the relation between inpouring flux and electromotor's rotate speed. Based on the model, the timing of DC motor is regarded as the core of the controlling precept. Then, the rectification circuit, controlling circuit, control algorithm and software monitor are researched and designed in detail. The silicon controlled rectifier is the hardcore of actiyator which has reactive circuit, and the controller is based on the industrial control computer. The software monitor realizes the control algorithm and process monitoring.The research in this paper not only improves the test atmosphere of electromagnetic fast casting-rolling, but also advances the theory in this area and promotes the development of aluminum machining technology.
