Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel strip annealing, in particular to a device for rapid cooling of stainless steel strip after annealing. Background Art

[0002] The purpose of annealing stainless steel strip is to make the stainless steel obtain the best performance or to create necessary conditions for stainless steel users to carry out cold and hot processing of stainless steel. Stainless steel needs to be heat treated before leaving the factory. Heat treatment is divided into annealing, normalizing, quenching, tempering and other methods, which we collectively call annealing.

[0003] After searching, a rapid cooling device of a continuous annealing unit for steel strips with a publication number of CN218291046U in the prior art is found. The rapid cooling device of the continuous annealing unit for steel strips drives multiple moving components to start under the action of an adjusting component. Under the action of multiple moving components, the jet seats are moved so that multiple jet seats are close to the steel strip. The cooling device of the device is arranged in the middle of the steel strip for cooling, but the edge of the steel strip has no cooling effect. Due to the uneven temperature of the steel strip, it is very easy to have wave edges, etc., which affects the production effect.

[0004] After searching, a strip steel cooling device for strip steel production with a notice number of CN220269794U in the prior art is installed. The water temperature inside the water pipe is volatilized by installing a fan, and the low water temperature is transported to the inside of the processing box, so as to better cool the strip steel. The filter plate is provided with uniform square holes, and the cooling area can be well maintained during cooling. The first water pipe installed inside the water pipe is circulated through the water pump, and the steel strip is cooled through the water pipe and the fan. It is used in the case where the annealing temperature of the steel strip is high and air cooling is adopted. The interior of the device is sealed, and the air needs to pass through the water pipe to cool the gas first before the cooled gas can be blown onto the steel strip, resulting in slow cooling.

[0005] According to the prior art, it is found that during the annealing and cooling of the existing strip, the cooling speeds at the edges and the middle are different, which easily leads to wave edges. At the same time, the cooling speed of the existing cooling equipment is slow. Therefore, a device for rapid cooling of stainless steel strip after annealing, which has direct blowing of cooling gas and water cooling and also has edge cooling, is proposed to solve the above problems. Summary of the invention

[0006] The utility model aims to overcome the deficiencies in the prior art and provides a device for rapid cooling of stainless steel strip after annealing. By providing an adjustable cooling gas mechanism and a water flow control mechanism, the temperature of the steel strip can be accurately controlled, and the two can be used simultaneously to accelerate the cooling speed. By providing edge cooling mechanisms on both sides, it is prevented that the cooling speeds of the edge and the middle of the steel strip are different, thereby preventing the occurrence of wavy edges.

[0033] Working principle: During use, the steel strip enters the transport roller 4 through the feed ports on both sides of the box body. According to requirements, the water flow control mechanism 2, the edge cooling mechanism 3, and the adjustable cooling gas mechanism 5 are started to cool the steel strip to different degrees. Cooling water is pressurized into the spray pipe 26 through an external device and a water inlet pipe, and water is discharged through the water outlet adjusting component 27 to cool the steel strip. The rotating motor on the lead screw frame 21 drives the lead screw to rotate, driving the spray pipe 26 to different heights, so that the water outlet adjusting component approaches or moves away from the steel strip, increasing or decreasing the local contact water volume of the steel strip and enhancing the cooling effect. At the same time, the water pressure is adjusted in cooperation with the water outlet adjusting component to prevent the situation that the temperature of different materials is affected by different water pressures and the steel strip deforms and cools too quickly. Through the adjustable cooling gas mechanism 5, by swinging the air outlet angle of the swing air inlet pipe 52, the different distances between the swing air inlet pipe 52 and the steel strip are adjusted. The more inclined the air inlet pipe 52 is, the more dispersed the amount of cooling gas reaching the steel strip, and the smaller the cooling effect, which is convenient for the staff to control the temperature. Through the edge cooling mechanism 3, the edge of the steel strip is cooled to prevent quality problems such as cracking of the steel strip caused by uneven cooling.
