Composition, structure and surface inspection method of process copper ingot
1. The chemical composition of copper ingot was determined by imported spectrometer.
2. Cut a copper ingot, polish the set process section and conduct visual inspection.
3. High ammonium sulfate solution was prepared according to the formula to detect the microstructure of copper ingot.
4. Take the copper solution from the smelting process for cup-shaped detection of the surface of the copper ingot.
