Screw Production Process
First, the purpose is to heat the wire to a proper temperature, keep it for a certain time, then cool it slowly, so as to adjust the crystalline structure, reduce the hardness and improve the processability of the wire at room temperature. _2. Work flow:
(1) Feeding: The products that need to be treated should be hoisted in the furnace, and the cover of the furnace should be tightened. Generally, 7 volumes (about 1.2 tons/volume) can be processed simultaneously in one furnace. A kind of
(2) Warming up: Slowly raise the temperature in the furnace (about 3-4 hours) to the specified temperature. Chinese style
Thirdly, heat preservation: material 1018 and 1022 wires are kept for 4-6 hours at 680-715, material 10B21, 1039, CH38F wires are kept for 5.5-7.5 h at 740-760. A kind of
(4) Cooling: Slow down the temperature in the furnace (about 3-4 hours) to below 550 (?) C, then cool down with the furnace to normal temperature. Quality control:
1. Hardness: The hardness of 1018 and 1022 wire is HV120-170 after annealing, and that of medium carbon wire is HV120-180 after annealing. A kind of
2. Appearance: No oxide film and decarbonization are allowed on the surface.
