Description

Wire coiling unit and wire manufacturing apparatus having the same

The present invention relates to a wire rod winding unit and a wire rod manufacturing apparatus comprising the same.

In general, the wire rod is heated to a billet material made in a steelmaking process or a steel sheet process in a state where hot rolling is possible, and through a series of rolling processes, its cross section gradually decreases to obtain a wire coil having a desired dimension. Say fair.

The wire rod made in the process of wire rod rolling has a total length of about 500m to 10km and cannot be stored in a straight line, so products are obtained in the form of coils wound in a circle, and this is called winding.

The winding process is a process of winding the wire coil in a cylindrical facility called a reeler, and is composed of a drum part that forms the outer diameter of the reeler and a fork pin that forms the inner diameter, and wires in the space between them. The coil enters and winds up.

In addition, in order to wind the wire coil, the reel is rotated. At this time, the fork pin portion, which is coupled to the lower portion of the drum and extends upward, is eccentrically rotated by the shaking of the upper end, which is a free end. Accordingly, the fork pin portion causes friction with the wire coil, thereby causing problems such as scratching on the wire coil.

In addition, the reeler convects the upper portion of the drum portion where the upper end is opened because the leading end portion of the wire coil entering the beginning of the winding process is laid under the drum portion, while the rear end portion of the wire coil entering the late winding process is wound above the drum portion. Due to heat loss, a temperature difference occurs between the upper side and the lower side of the wire coil.

However, due to the difference in the cooling rate for each position of the wire coil due to the difference in the amount of heat loss in the inside of the reeler, a problem arises in that the material tensile strength and the microstructure quality of the wire coil are different.
