Optimization and Analysis of Aluminum Alloy Ignition Seat Casting Process Based on Orthogonal Experiment

The pouring temperature, pouring speed and mold preheating temperature of the aluminum alloy ignition seat were optimized by using the Anycasting software and the orthogonal casting method. The filling and solidification under different conditions were analyzed, and the position and size of the casting shrinkage cavity and porosity positions were predicted. The results show that when the pouring temperature is 630℃, the pouring speed is 40 mm/s, the mold preheating temperature is 220℃, the shrinkage and shrinkage defects of aluminum alloy ignition seat are the least.
