Abstract
The utility model discloses a medium plate cooling and spraying device, which comprises an upper spraying box. A plurality of upper headers are arranged on the upper spraying box communicated with a main header through a cooling water distribution pipe, and a regulating valve is arranged on the cooling water distribution pipe. Compared with the prior art, the medium plate cooling and spraying device has simple structure and low cost without complex water quality and water flow control, the upper spraying box has stable water level and convenient work process control, and cooling temperature is even, precision is high, short in system response time. In addition, the medium plate cooling and spraying device has even flow distribution in width direction, guarantees cooling evenness of steel plates in the width direction, cooling zone can realize extremely small segmentation, thereby favoring segmented control of steel plates, and guaranteeing the cooling evenness of steel plates in length direction, and energy consumption and maintenance cost are extremely low.
Description
Technical field
The utility model relates to a kind of cooling sprayer, especially a kind of cooling sprayer that is used for the medium plate production process.
Background technology
In the medium plate production process, cooling system has directly influenced the quality of the steel plate of being produced.Cut deal rolls back control cooling procedure, not only will guarantee the control accuracy of cooling velocity and final cooling temperature, also will guarantee the uniformity of steel billet temperature control.Simultaneously, the response of cooling system also has a significant impact control accuracy.Accelerate the response time of cooling system, can better guarantee control accuracy.The cooling system of existing medium plate, or on the cooling control accuracy, be difficult to reach higher level, otherwise complex structure, the cost height.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, cost is low, control is convenient, precision is high medium plate cooling sprayer.
In order to solve the problems of the technologies described above, the utility model provides a kind of medium plate cooling sprayer, comprises spraying box, and the described spraying box of going up is provided with many upper headers, and the described spraying box of going up is connected with main collector by cooling water pipe; Described cooling water pipe is provided with control valve.
Further, described upper header is connected to described top of going up spraying box, and the described top, spraying box side of going up is provided with overflow pipe, and the link position of described overflow pipe and last spraying box is lower than the link position of described upper header and last spraying box.
Further, described upper header is connected on the roof of described upward spraying box, and described upper header is inverted U-shaped, and its mouth spray is downward.
Further, described overflow pipe is provided with overflow valve.
Further, described control valve is a pneumatic control valve.
Further, described control valve one side is provided with bypass pipe, and described bypass pipe is provided with by-passing valve.
The utility model compared with prior art, it is simple in structure, cost is low, does not need the control of complicated water quality and current, last spraying box stable level, course of work control makes things convenient for; Chilling temperature is all spent, the precision height, and system response time is short.In addition, the utility model flow on width is evenly distributed, and has guaranteed the cooling uniformity on the steel plate width direction; Cooled region can be realized very little segmentation, is beneficial to steel plate segmentation control, guarantees the cooling uniformity on the steel plate length direction; Energy consumption and maintenance cost are also low.
Description of drawings
Fig. 1 is the structural representation of medium plate cooling sprayer of the present utility model;
Fig. 2 goes up the schematic diagram that the spraying box upper pipeline is arranged in the spray equipment of the present utility model.
Among the figure: 1. go up spraying box, 2. upper header, 3. overflow pipe, 4. cooling water pipe, 5. bypass pipe, 6. control valve, 7. steel plate, 8. slag runner, 9. overflow valve, 10. main collector.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
As depicted in figs. 1 and 2, medium plate cooling sprayer of the present invention comprises spraying box 1, and last spraying box 1 is provided with many upper headers 2, and the described spraying box 1 of going up is connected with main collector 10 by cooling water pipe 4; Cooling water pipe 4 is provided with control valve 6.The water spray of upper header 2 adopts computer control, by importing the opening degree of 4～20 milliamperes Current Control control valve 6, and then the spray flow of control upper header 2.Control valve 6 is preferably pneumatic control valve.
Can bypass pipe 5 be set in control valve 6 one sides, the by-passing valve (not shown) is set on bypass pipe 5.So, when not spraying water, can be full of all the time to guarantee the cooling water in the spraying box 1 by bypass pipe 5 upwards spraying box 1 moisturizings, thus the response speed of raising cooling system.
The course of work of the present invention is: after steel plate was finished last rolling pass, control valve 6 was opened, and overflow valve 9 cuts out, and main collector 10 is by cooling water pipe 4 upwards spraying box 1 moisturizings.Water in the last spraying box 1 is because pressure differential flows to steel plate 7 upper surfaces by upper header 2.After steel plate left, control valve 6 cut out, and overflow valve 9 is opened.The cooling water of main collector 10 can be by bypass pipe 5 with certain flow (3m for example
3/ h) flowing to upward spraying box 1, unnecessary cooling water flows to slag runner by overflow pipe 3.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
