Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding machine which prevents the temperature of a hot strip from decreasing during winding by providing a heatable attachment on the outer periphery of a segment.

The hot strip rolled in a hot strip mill is wound into a winder at a high temperature, but heat transfer occurs between the reel part of the winder and the hot strip. As a result, the hot strip is cooled in the reel section, and the reel section is heated more than necessary. Cooling of the hot strip during winding is extremely inconvenient for the hot strip as the internal structure changes depending on the temperature, so the cooled part must be cut off or removed before proceeding to the next process. There are some types of steel that require reheating to adjust their internal structure. In particular, when cutting and removing, the cooling portion extends from the beginning to more than ten turns, resulting in extremely poor yield.

The present invention was made with the aim of solving such problems, improving yields, and simplifying the process.The present invention was created with the aim of improving yield and simplifying the process by attaching an arc-shaped attachment to the reel segment and installing a device that heats the outer periphery of the attachment. The present invention relates to a hot strip winding machine, which is characterized in that it is built into an attachment.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows a part of the reel of the hot strip winding machine according to the present invention, in which an attachment 3 is provided on the outer periphery of a heat insulating material 2 such as asbestos, which is formed to a radius that allows it to come into close contact with the outer periphery of a segment 1. The material 2 and the attachment 3 form an arc-shaped part divided into the same number as the number of segments 1, and the attachment 3
A groove 4 extending in the axial direction of the reel is provided on the outer periphery of the reel, and a heating element 5 such as an electric heater is installed in the groove 4.
The upper surface of the groove 4 is closed with a lid 6 so as to have the same radius as the outer circumference of the attachment 3, and the attachment 3 is fixed to the segment 1 with a bolt 7.

When the heating element 5 is an electric heater, a known slip ring is attached to the required position of the reel,
Power can be supplied to the heater from the outside via the slip ring. Further, instead of an electric heater, steam may be used as the heating element and the steam may be flowed into the groove 5 to perform heating.

The hot strip is wound around the outer circumference of the attachment by the rotation of the winding machine, but since the attachment 3 is heated by the heating element 5, the hot strip is wound without being cooled. Since the heat insulating material 2 is provided on the inner periphery, less heat escapes from the segment 1 to the reel side.

FIG. 2 shows another embodiment of the hot strip winding machine according to the present invention, in which the insulation material is eliminated and the attachment 3 is directly attached to the outer circumference of the segment 1. An air layer 8 is provided on the circumferential side to minimize the area in which the attachment 3 contacts the segment 1 and to prevent heat from being transmitted to the segment 1.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

According to the hot strip winding machine of the present invention,
Since the temperature drop of the hot strip can be prevented, the internal structure of the hot strip will not change, which can improve the yield, and since the process of reheating the hot strip is no longer necessary, the process can be simplified. Various excellent effects can be achieved.
