Embodiment 1
[0030] Set the tubular furnace annealing region 6-1, the buffer 6-2 and the compensation zone 6-3 temperature are 750 ° C, 500 ° C, and 300 ° C, each region is heated, and a thermocouple is provided in each region. Temperature measurement. When the heating is started, when the temperature reaches the set temperature, then after 20 min, the motor 5 is activated, and the set roller is set to 0.38 mm / min, so that the motor 5 is idled for 2min, and the diameter φ is 3.5 mm TC4 disc The wire is passed through the roller 3, and the tube furnace 6 is sent to each heating zone by the tubular furnace, and then exit the tube furnace 6 after the lower section is fed into the tank, finally grind, polished to the finished product. The finished product refers to the GB / T 228.1-2010 to perform a room temperature tensile test and record the elongation, and the tensile test gauge is selected from 100 mm. The results show that after an annealing of the present method and the device, the silk ma...
Embodiment 2
[0032] Set the tube furnace annealing region 6-1, the buffer 6-2 and the compensation area 6-3 temperature are 650 ° C, 450 ° C and 200 ° C, start heating, when the temperature of each zone reaches the set temperature, continues to heat the insulation 20min, start The motor 5 simultaneously sets the roller 3 revolution of 0.38 mm / min to cause the motor 5 to pass through 2min, pass the disk roll TA3 wire of the diameter φ of 3.5 mm through the roller, and feed the tubular furnace 6 to pass the tube. The furnace has a heating zone, and then exit the tubular furnace 6 will be fed into the receiving tank, and finally grind, polished to the finished product. The finished product reference GB / T 228.1-2010 is a room temperature tensile test, and the tensile test gauge is selected to be 100mm. The results show that after an annealing of the online annealing, the wire is increased from 7.0% to 10% compared to the conventional online annealing mode. In the present embodiment, the appara...
Embodiment 3
[0034]The tubular furnace annealing region 6-1 is provided, and the buffer 6-2 and the compensation zone 6-3 are 800 ° C, 500 ° C, and 300 ° C, start heating. When the temperature of each region reaches the set temperature, it continues to heat insulation for 20 minutes. The motor 5 is activated, and the roller 3 rotation speed is set to 0.38 mm / min, so that the motor 5 is idled by 2min, passing the TC4 disc of a diameter φ of 2 mm through the roller 3, and feeds the tube furnace 6 to pass in turn The tube furnace is heated, and then the tube furnace 6 will be sent to the tank, finally grind, and polished to the finished product. The finished product refers to the GB / T228.1-2010 to perform a room temperature tensile test, and the tensile test gauge is selected from 100 mm. The results show that after the online annealing is used to use the method and the device, the silk material elongation is increased from 4.0% to 8% compared to the conventional online annealing mode, and th...
