【考案の詳細な説明】 本考案は、鋼板冷却装置に関するものである。[Detailed explanation of the idea] The present invention relates to a steel plate cooling device.
従来の鋼板冷却装置は、たとえば第1図に示す

板aは材質によつては空冷する場合がある。この
時は、この装置を通過させる。 In a conventional steel plate cooling system, for example, as shown in Fig. 1, a red-hot steel plate a is placed on a roll b supported by a bearing c, and when the moving steel plate is water-cooled, high-pressure water sent from a pump h is used. is injected from the nozzle d from the main water supply pipe g through the water supply pipe e. Depending on the material, the steel plate a may be air-cooled. At this time, it passes through this device.
この際、給水遮断弁を閉止してノズルdへの給

い。 At this time, close the water supply cutoff valve to stop the water supply to the nozzle d, open the water drain valve i of the water drain device, drain the water from the nozzle d through the water drain pipe j, and wait until the water drains (stop the water supply). However, in the final stages of water draining, the force that allows the residual water in the pipe to fall weakens, prolonging the water draining time. In addition, if the water supply cutoff valve f is used for a long time, the valve seat etc. may wear out and foreign objects may become trapped.
Gradually, watertightness becomes insufficient and a small amount of leakage occurs. The remaining water in these nozzles d drips from the nozzles d by the piping drive and falls on the red-hot steel plate a, creating a pattern called a flower pattern and spoiling the appearance. Therefore, the operator of the apparatus waits for the water to drain completely before starting the next operation, which significantly reduces the production efficiency of the apparatus and causes great fatigue for the operator.
本考案は、水切れ時間が大幅に短縮されるとと
もに、給水遮断弁のリークを吸収することがで
き、かつ、運転管理の容易な鋼板冷却装置を提供
することを目的とするものである。 An object of the present invention is to provide a steel plate cooling device that can significantly shorten the water drain time, absorb leaks from a water supply cutoff valve, and is easy to operate and manage.
このため、本考案の構成は、移動する鋼板より

ことを特徴としている。 For this reason, the configuration of the present invention is such that, in a cooling device having a nozzle provided above a moving steel plate and a water draining device for removing water from this nozzle, a water supply cutoff valve provided in a water supply pipe to the nozzle is provided. It is characterized by being equipped with a compressed air blowing device installed at a portion not higher than the highest water level of residual water in the closed state.
