Description of the Prior Art Cooling water stays on the inner surface of the H-section steel at the time of manufacturing the H-section steel, and the cooling water flows on the upper surface of the web to non-uniformly cool the web, which causes a temperature difference in the longitudinal direction of the H-section steel. This causes a temperature difference between the flange and the web, which causes problems such as poor shape due to thermal stress and uneven performance due to uneven cooling.

が記載されている。Japanese Examined Patent Publication (Kokoku) No. 5-73806 discloses a method for controlling the cooling water on the upper inner surface of the H-section steel by an apparatus as shown in FIG. That is, it is described that the member 30 having a large number of holes 90 is arranged on the inner surface of the H-section steel upper portion, and the cooling water on the inner surface of the H-section steel upper portion is blocked by blowing out air from the holes 90.

吹かざるを得ず。空気量等に無駄が多くなる。However, in the apparatus shown in FIG. 4, the air blowing mechanism of the web portion and the flange portion are not independent, and the air blowing from the hole 90 is not independently supplied and controlled. In order to completely block the cooling water on the upper surface of the H-section steel, air must be supplied to each nozzle and blown at a large pressure and flow rate as compared with the case where air is controlled. There is much waste in the air volume.

吹かざるを得ず、ますます空気量等に無駄が多くなる。Although it is not mentioned in Japanese Examined Patent Publication No. 5-73806, it is practically difficult for the cooling water control device having the structure shown in FIG. In order to prevent the cooling water from leaking out from a portion where the air is weakly blown, a larger pressure and flow rate must be blown, and the amount of air and the like becomes more and more wasteful.

全に行うことができる。In the cooling water control device of the present invention, the nozzles for injecting the cooling water control fluid are independently provided on the flange side and the web side, respectively, and the flow rate and pressure of each nozzle are independently controlled. By making it controllable, the fluid can be ejected under the condition suitable for the situation of each part. Further, by making the main body into a box shape and arranging it in proximity to the H-shaped steel web and the flange, the flow of cooling water can be blocked by the cooling water control device itself, and the cooling water will try to leak out. The flow passage can be narrowed to facilitate control of the cooling water, and the cooling water control fluid can completely eliminate the cooling water leaking from the cooling water control device. Therefore, the cooling water can be completely blocked in the region partitioned by the pair of cooling water control units of the cooling water control device, and the cooling water control of the upper inner surface of the H-section steel can be performed completely.

除去される。The cooling of the inner surface of the upper portion of the H-section steel in the region between the pair of cooling water control parts of this cooling water control device is, so to speak, the cooling in the longitudinal direction, the web and the flange at the same time, so that the cooling unevenness occurs. Without, uniform cooling is possible. As a result, it is possible to achieve uniform heat treatment and high performance such as high strength. The cooling water blocked by the cooling water control device is removed by overflowing from the upper part of the flange.

ジ、ウェブ間隔によって異なる。As shown in FIGS. 2 and 3, the blowing angle θ of the fluid blown out from the cooling water control device causes leakage at the flange and the web so as to give momentum against the cooling water which is about to leak. It is desirable that the direction is 90 ° or more and 150 ° or less with respect to the flow direction of the cooling water that is about to come out. However, the optimum value of this setting varies depending on the type, pressure, flow rate, etc. of the fluid blown out from the cooling water control device, the nozzle shape of the cooling water control device, the cooling water control device, the flange, and the web spacing.

Fixing and cooling the H-section steel while moving the cooling water control device, or cooling the H-section steel while moving both the H-section steel and the cooling water control device pair in the same direction or opposite directions. However, it goes without saying that the same effect can be obtained.

ある。Further, by changing the fluid used in this cooling water control device to water, air, etc., an optimal combination can be obtained according to the position setting of the cooling water control device and available utilities. It is possible to control the cooling water. Further, the cooling capacity control by this cooling water control device can also be realized. That is, for example, when the web is overcooled with respect to the flange, water is used as the fluid ejected from the nozzle portion on the flange side, and air is used as the fluid ejected from the nozzle portion on the web side. It is possible to improve the performance and control the temperature more strictly.

要になることは言うまでもない。By controlling the cooling water by the cooling water control device according to the present invention, the conventional problem of H
Since it becomes possible to uniformly cool the inner surface of the shaped steel, by using the cooling water control device according to the present invention,
Regarding the cooling of the outer surface of the H-section steel and the lower surface of the H-section steel, it is possible to perform sufficiently uniform cooling by cooling with a known spray nozzle or the like. Regarding the cooling of the outer surface of the H-section steel, the outer surface of the H-section steel is cooled by a known spray nozzle or the like at an intermediate position between the pair of cooling water control units in the cooling water control device according to the present invention, so that the flange outer surface can be cooled. There is no problem of splashing of cooling water from the spray nozzle or the like. Further, regarding the cooling of the lower surface of the H-section steel, all the cooling water splashes downward so that the cooling does not become uneven. However, it goes without saying that it is necessary to set conditions such as the flow rate and the injection angle for cooling the outer surface of the H-section steel and the lower surface of the H-section steel in accordance with the conditions such as the dimensions of the H-section steel.

It is possible to control by flow rate and pressure. As a result, the cooling water on the upper surface of the H-section steel is completely restricted to a specific place, and strict uniform cooling can be performed in the longitudinal direction of the H-section steel, so that a homogeneous and high-performance H-section steel can be manufactured.

When it is desired to improve the cooling capacity in this way, it may be possible to respond by blowing water from each nozzle. However, when injecting water, it is necessary to adjust the injection angle θ of the nozzle so that the injected water does not leak from the cooling water control device.
