The utility model adopts the technical proposal that: the online water-cooling regulation and control device of the anti-deformation rolling of the roller has a roller 1 and a rolled piece 2, and is characterized in that: a plurality of infrared temperature measuring probes 4 which are uniformly distributed are fixedly erected and installed above the axial central line of a roller body (particularly an upper roller shown in figure 1) of the roller 1; each infrared temperature measuring probe 4 is respectively connected with an independent temperature display screen 6 (shown in the sequence of figure 1) which is used for displaying real-time temperature in a one-to-one correspondence manner from left to right according to the distribution sequence of the infrared temperature measuring probes 4 through an independent cable 42, and the temperature display screens 6 are arranged in the operating room of an operator in a fixed sequence in order so as to correspond to different temperature measuring points one by one. It should be noted that the infrared temperature measurement probe 4 with the temperature display screen 6 belongs to a commercially available component, and the infrared temperature measurement probe 4 specially used in the metallurgical industry can be directly purchased and electrically connected with the corresponding temperature display screen 6; the circuit wiring connection belongs to the prior art and is not described in detail. And each infrared temperature measuring probe 4 carries out point-to-point temperature test on the surface of the roller body of the roller 1 from left to right. It should be noted that: compared with other temperature detection elements, the infrared temperature measurement probe 4 has the characteristic of realizing point-to-point temperature measurement, can meet the temperature detection requirement of a certain radial point of the axial equal division of the outer circumference of the roller body, and is selected. And a plurality of measuring points of the infrared temperature measuring probe 4 axially and uniformly divide the roller body of the roller 1 into a plurality of equal temperature measuring sections (such as 'uniform dividing A radial lines' which axially and uniformly divide the roller body 1 into equal parts as shown in figure 1). A plurality of nozzles 3 are horizontally and uniformly distributed and fixedly arranged right above the central line of the roller body of the roller 1, and the nozzles 3 are arranged corresponding to the temperature measuring points of each infrared temperature measuring probe 4 one by one so as to uniformly cool the roller body of the roller 1; to form a water curtain type cooling: the water column of each nozzle 3 sprays towards the right lower part uniformly, and the water column of each nozzle 3 sprays perpendicular to the upper surface of the top point of the roller body of the roller 1; and for realizing the temperature equalization regulation and control of water cooling: each nozzle 3 is manually adjusted in water flow rate through a remote independent manual adjusting valve 5, and the nozzles 3 and the corresponding manual adjusting valves 5 are connected in parallel to a hard cooling liquid supply pipeline 31 for supplying cooling liquid after being connected in series and in one-to-one correspondence through hard pipelines as shown in fig. 1.

That is, the infrared temperature measuring probe 4 may be provided at any point on the radial line of the "bisector a radial line" described later. Because the roller continuously rotates, the temperature of any point on the radial line of the equal division A is the same, so that the requirement of accurate temperature monitoring of the nozzle 3 corresponding to the measuring point can be met by arranging the infrared temperature measuring probe 4 at the radial non-top position of the roller body of the roller.

Specifically, when the real-time temperature of the measuring point detected by the infrared temperature measuring probe 4 of a certain measuring point is increased to be higher than the standard temperature, the opening degree of a manual regulating valve 5 corresponding to the measuring point is manually regulated and increased corresponding to the measuring point, and the water flow of a nozzle 3 corresponding to the measuring point is increased, so that the temperature of a roller body of a spraying area corresponding to the measuring point is reduced; similarly, when the real-time temperature of the measuring point detected by the infrared temperature measuring probe 4 of a certain measuring point is lower than the standard temperature, the opening degree of the manual regulating valve 5 is manually reduced corresponding to the measuring point, the water flow of the nozzle 3 corresponding to the measuring point is reduced, and the temperature of the roller body of the spraying area of the measuring point is correspondingly increased.

For example, the infrared temperature measuring probe 4 deflects at the swing angle position of 5-10 degrees along the vertex of the radial line A and the radial line A to detect the temperature of a certain point in the radial direction of the roller body.
