Abstract
The invention relates to the field of hot rolling, in particular to a cooling device and a cooling method for a roller. The cooling device for the roller comprises at least one set of cooling devices, wherein each cooling device is provided with a water pipe filled with cooling water and provided with a water pipe control valve, and an air pipe filled with compressed air and provided with an air pipe control valve; both the water pipe and the air pipe are connected to an arc-shaped water and air outlet end; and a plurality of strip-shaped spray nozzles are uniformly formed in the outer side of the water and air outlet end. According to the cooling device and the cooling method, the roller is cooled and blow-dried in water and air outlet directions by adopting the arc-shaped water and air outlet end, so that the requirements that the roller should be quickly cooled after rolling and the surface of the roller should be dried after cooling are met, the cooling effect of the roller is improved, and the service life of the roller is prolonged.
Description
technical field [0001] The invention relates to the field of hot rolling, in particular to a roll cooling device and a cooling method thereof. Background technique [0002] For hot rolling, due to the high temperature of the rolled steel strip (generally around 1000°C), corresponding requirements are put forward for the temperature control of the rolls. During the rolling process of general rolls (that is, work rolls), the instantaneous temperature may reach 700-800°C. After a certain period of water cooling (the gap between the rolling strips), the temperature is roughly controlled at about 80°C. In special cases Under normal circumstances, the temperature of the roll may reach about 100°C. During the rolling process, there is a certain deviation of the strip steel, resulting in an irregular temperature distribution of the roll. At this time, the roll shape of the roll will be irregular due to the influence of temperature (thermal crown). Roll shape; at the same time, aff...
