Abstract

A new type of continuous production technology of low pressure casting for magnesium alloy was developed. Using the duplex station design, the technology achieves the switch between two pieces of low pressure casting equipment of magnesium alloy at different stations through the furnace transportation vehicle's movements, ensuring the continuous production of magnesium alloy casting. A level suspension technology has been used in the pressure control system, which realizes the precise suspension control of metal level in riser tube orifice, reduces the oxide inclusion defects and improves the production efficiency. The developed fuzzy-PID hybrid control technology possesses high precision during the course of low pressure casting process for magnesium alloy. The pressure control error is less than 0.5 kPa.
