Annealing Wire Process

Working of Annealing Wire Process 

 a. Two hours heating to 650°C-700°C

 b. Keeping Temperature 650°C-700°Cfor 2 hours

 c. Keep the tube in the furnace, cooling for 4 hours till the temperature is about 300°C

 d. Taking out of the tube put another one in

 e. When the tube temperature is below 170°C, take the wire out
