Abstract

PURPOSE:To enable the use of a large amount of coolant and also the fine control of the flow rate of coolant, by providing 4 steps of cooling headers to the passage of coolant. CONSTITUTION:A coolant is supplied to a piping 32 of an upper frame through a coolant supplying piping, and is successively sent to upper cooling headers 22, 23 from the piping 32 to be jetted onto the surface of a thick steel plate 1 through nozzles 26. Further, the control of flow rate of the coolant is performed by providing flow-regulating valves to e.g. supplying ports of cooling headers 22, 23, 24, and providing further a flow regulating valve to each nozzle 26. That is, in a case of a plate having comparatively thin thickness, the flow rate of coolant can be made small, then the coolant is jetted only from the headers 22, 24 without supplying the coolant to the headers 23, 25 to perform a temper cooling, or the flow rate is controlled by the flow regulating valve attached to each nozzle 26 for the purpose of giving a crown to the flow rate.

Thus, according to the above-mentioned prior art! The descending part is installed inside the gate-shaped stand consisting of the support column 9 and the fixed beam 0, and the supply piping to the cooling rudder is taken into all the cooling headers, 2 from the left and right, so there is only 1. The structure is extremely complex, and not only does it have difficulties in maintainability, but the four pieces of equipment also tend to be tall and wide (which tends to increase the area of landslides within the factory). Recently, the development of new products (small) has become active, and the capacity of the cooling medium injected onto the surface of thick steel plates has become larger than before, and delicate controls have been developed.
However, it is becoming difficult to respond using conventional technologies such as child chains.

, (I'C shows that the edge portion 1c of the thick steel plate shown in FIG. 8 tends to have a faster cooling rate than the center portion 1a, but -
In order to make the material uniform in the width direction, as shown in Figure 8, it is necessary to make the cooling medium fan two crowns in the width direction of the plate to make the cooling rate uniform. Due to the increase in the width from the thin plate thickness area to the thick plate thickness area, and the increase in the speed of one plate pass, it is impossible to control the flow Jffl in a wide range from small capacity to large capacity with a single pair of cooling headers. This allows for delicate control of fluid flow (the cooling header can be placed 2 times each on the top and bottom).
