Embodiment Construction
[0021] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.
[0022] Please refer to Figure 1 to Figure 2 , Figure 1 to Figure 2 It is a flowchart of a control method for improving the metallographic structure of a heat-treated steel wire according to an embodiment of the present invention. A control method for improving the metallographic structure of heat-treated steel wire according to the present invention comprises the following steps:
[0023] S1. The first steel wire is drawn for the first time to obtain the second steel wire. Preferably, the first drawing is rough drawn by dry drawing. In practical application, the diameter of the first material steel wire can be 5.5 mm, and the diameter of the second material steel wire obtained through the first drawing can be 2.8 mm.
[0024] S2. Carrying out the first heat treatme...
