Simulation and Implementation for the Speed Control System of Horizontal Continuous Casting Dragger for Copper

Abstract

The levels of continuous casting process of copper and copper alloy billet have many advantages, such as taking small footprint, low investment and the shorter flow. Recently, it develops very quickly all over the world. This article designs the dummy body drive control system based on the DSP digital signal processing chips, inverter and variable speed induction motor, and uses the unique process that space vector pulse width modulation strategy can achieve continuous casting horizontal tractor’s four beats to realize continuous casting process’ high-quality, stable and reliable implementation. Early in the 19th century, German Bismarck had proposed a continuous casting process in his patent. The development of this method in the copper industry began in 1940s, the type of equipment went through belt type, vibration mold, vertical traction type, tilt casting type and Horizontal traction type [1, 2]. Now, horizontal traction, as the most popular method abroad, because its products don’t need straightening, and consistency of properties along the length and high density of grain lead to the improvements of mechanical properties and electrical properties, its superiority in product quality and production efficiency is obvious. The design combined the modern AC variable speed control and advanced SCM control technology and traction continuous casting process to design a Speed controller of horizontal continuous casting of copper traction motor, its performance is similar with to dummy industrial control computer and AC servo motor drive control system, but the configuration of the hardware is less than half the price.
