Embodiment 1
[0008] Specifications: thickness 0.45mm radio frequency cable tape, processing technology adopts:
[0009] 1. Melting and casting: choose high-purity cathode copper with trimmed edges, and make ingredients according to weight ratio. The sum of each component is 100%. Put it into a cored melting furnace for melting. Melting temperature: 1160°C-1250°C, metal liquid level in the furnace Charcoal is used for covering protection; the casting method adopts semi-continuous casting to form ingots; the smelted metal solution is transferred to the holding furnace of the casting equipment for heat preservation, and protective gas is used for protection and covering protection in the furnace, and the crystallizer is covered and protected by gas. Temperature: 1100°C-1180°C;
[0010] 2. Heating: Use a heating furnace to heat the ingot, heating temperature: 830°C-920°C, heating time: 2h-4h;
[0011] 3. Hot rolling: use hot rolling mills for hot rolling blanking, hot rolling processing rate:...
