Abstract

PURPOSE:To regulate and cool satisfactorily a spiral coil of a rolled wire rod and to make the heat-treated structure thereof uniform by holding the respective loop parts of said coil in a spaced state and conveying the coil in a duct in which cold air flows and water mist is sprayed. CONSTITUTION:A rolled wire rod is formed to a spriral coil 12 and discharged from a looper 11 and is conveyed at a prescribed pitch by a conveyor 16. Bars 36 of a holding conveyor 23 which is cyclically turned above enter between the adjacent loop parts 12a of the coil 12 when the loop parts 12a incline gradually while the coil is conveyed, thereby receiving the loop parts in the mid-way of inclination. The loop parts 12a are thus held in the spaced state at a prescribed distance without being overlapped on each other and are conveyed into a duct 46 where the coil is regulated and cooled by the cold air in the direction opposite from the conveying direction from a fan and the water mist sprayed from a water mist generator 55.

Then, each loop portion (XZa) of the discharged spiral coil (12) is transferred to the fifth loop portion (XZa) on the conveyor Q81.
As shown in the figure, it gradually tilts, but at this time, the holding conveyor (four bars) (three bars are adjacent to each other in the loop part (12a
) and catch each loop part (12a) in the middle of tilting, thereby allowing the adjacent loop part (12a)
2a) do not overlap and are spaced apart by a predetermined distance, each loop portion (12a) is securely held in a predetermined forward tilted posture (approximately 45 degrees in the example) by the bar, and in this state, the spiral The shaped coil Q21 is conveyed at a predetermined pitch by a conveyor (16).

In the above case, within the duct 146), each loop part (iza) is held in a predetermined forward tilted posture by the bar (30) with the adjacent loop parts (12a) not overlapping but separated by a predetermined distance. So a spiral coil!
+21 can be cooled more uniformly than by cooling air and water, and the heat treatment structure of the spiral coil (12) can be made uniform.

In addition, each blower sends cooling air from the rear of the duct (46) to the front in the opposite direction to the conveying direction of the spiral coil 02). The contact time of the cooling air with the helical coil 021 is much longer than in the past, resulting in high cooling efficiency.

Furthermore, since each loop part (12a) in the duct (461) is held in a predetermined forward tilted posture, each loop part (12a)
tries to bend forward and diagonally downward, but as mentioned above, since the cooling air is being sent in the opposite direction to the conveying direction of the spiral coil, the cooling air is deflected at each loop part (
12a) can be suitably prevented from bending, and a heat-treated structure with little deformation can be obtained.

In addition, in the above case, the cooling air is sent in a turbulent state from each blower (through the air blower) to the blower duct (inside the air duct), and then to the duct ( 4!, and in the duct of Kazedo Bogie Co., Ltd., each loop part (12a) receives approximately equal wind pressure from the cooling air, so the temperature of the spiral coil (121) changes. By placing the position in the temperature zone within the duct (N) of the wind platform vehicle □□□, it is possible to extremely suitably prevent the bending of each loop portion (12a) of the spiral coil (121) due to softening near the transformation point. Furthermore, a heat-treated structure with less deformation can be obtained.

In addition, a conduit is provided at an appropriate location in the duct (a), and the heat treatment temperature of the helical coil (121) is controlled by spraying water mist from the spraying part of the conduit onto the helical coil ab. Because of this, together with the cooling caused by the cooling air,
It is possible to cool the helical coil σ in a well controlled manner, and to obtain a desired uniform heat-treated structure with little deformation.

On both the left and right sides of the wind exhaust truck C, there are a suction pipe (exhaust pipe (c) 9), a suction pipe that communicates with the inside of the duct (4 (2) and its side), and a discharge pipe (
A pair of air vents are arranged in a communicating manner, and the exhaust system is movable, and the cooling air that passes through the duct OQ is transferred to the suction tube

As detailed above, according to the present invention, in a duct through which cooling air passes and water mist is sprayed, each loop portion of a helical coil is arranged in front of a predetermined distance at a predetermined distance from an adjacent loop portion. Since the helical coil is held in an inclined position by the holding conveyor, the helical coil can be cooled uniformly, and the heat treatment structure of the helical coil can be made uniform.

In addition, since the blower sends the cooling air in the direction opposite to the direction in which the spiral coil is conveyed, the contact time of the cooling air sent by each blower with the spiral coil is longer than before.
Not only is the cooling efficiency high, but also the wind pressure of the cooling air can suitably prevent the forward and downward deflection of each loop portion, making it possible to obtain a heat-treated structure with little deformation.

Furthermore, the water mist generator sprays water mist onto the spiral coil inside the duct to control the heat treatment temperature of the spiral coil. It is possible to achieve well-controlled cooling and to obtain a desired uniform heat-treated structure with little deformation.

本発明は上記各種の利点を有し、実益大である。The present invention has the above-mentioned various advantages and is of great practical benefit.
