Copper Clad Steel Wire Annealing Furnace
This copper clad steel wire annealing furnace is divided into intelligent temperature control, technology can be traced, aluminum silicate fiber furnace lining, silicone rubber sealed and water circulation cooling, efficient and energy saving. Widely used in non-oxidative decarburization annealing of spring steel, tool steel, bearing steel strip and wire
Heat treatment process designed in copper clad steel field:
Plated copper grounding flat wire and round wire will undergo heat treatment, that is to say, the internal structure of steel wire will change essentially through the temperature change, and the steel wire with different components will have different critical points of optimal structure at different temperatures. Upgrade copper clad steel products to heat treatment process, mainly including 1. Medium temperature tempering 2. Annealing 3. Pipe annealing
1. Medium temperature tempering: heating time is 1.5-2.5 hours, holding time is 3-5 hours, and temperature is 400-550 degrees. This heat treatment is used for drawing high-strength copper clad steel.
2. Annealing: the constant temperature is 700-800 degrees, the time is 6-10 hours, and the furnace can be cooled for 12 hours. The furnace can be discharged when the temperature is below 300 degrees, and the cooling time can also be extended. The purpose of extending the cooling time is to make the structure better fused and extend better.
3. Pipe annealing: 790-500 degree pipe temperature decreasing zone, 200 degree drying at the outlet, used for continuous annealing of copper clad steel fine wire, the pipe annealing equipment is generally designed with online hot dip tinning process at the same time.
