Description of core equipment of automobile aluminum wheel production line
Smelting and casting stage
1. liquid aluminum smelting equipment
electromagnetic induction melting furnace : high efficiency melting aluminum ingot (containing silicon, magnesium and other alloys), equipped with degasing refining device (argon impurity removal) to ensure the purity of liquid metal.
low pressure casting machine : the liquid aluminum is injected into the mold through the pressure, forming the wheel hub blank (mainstream process), the mold life of more than 100,000 times, support multi-cavity synchronous casting.
2, heat treatment equipment
solution treatment furnace : the blank is heated to 500°C and then cooled by water to improve the strength of the material.
aging furnace : Low temperature tempering (150-200°C) stabilizes material microstructure.
2. Technology trends
digital twin : virtual debugging of production line, process optimization efficiency increased by 30%.
green manufacturing : smelting waste heat recovery, water-based paint instead of solvent paint (VOC emission reduction of 90%).
AI quality inspection : deep learning to identify defects, missed detection rate < 0.1%.
First, mechanical processing
