[0014] A device for fixing water strips in a continuous casting zone with equal spacing comprises a water inlet 1, a connecting pipe 2, a water nozzle mounting pipe 3, a single-sided water strip, a billet 9 and a water nozzle 10. The single-sided water strips are provided in four groups, which are respectively arranged on the outside of the four sides of the billet 9. The single-sided water strips are composed of square tubes. The connecting pipe 2 is installed at the top of the square tube. The water inlet 1 is connected to the square tube through the connecting pipe 2. The water nozzle mounting pipe 3 is installed on the side of the square tube close to the billet 9. The water nozzle 10 is connected to the water nozzle mounting pipe 3. The distance between each water nozzle 10 and the surface of the billet 9 is the same.

[0015] The single-sided water strip on each outer side of the ingot 9 is composed of two square tubes, each of which is provided with three water nozzles 10, which are arranged in sequence from top to bottom.

[0016] The length of the water nozzle mounting pipe 3 matches the spraying angle of the water nozzle 10 and the curvature of the casting billet 9 to ensure that the distance between the water nozzle 10 and the surface of the casting billet 9 is the same.

[0017] The spray angle of the water nozzle 10 is between 55 and 65 degrees, and the distribution position of the water nozzle 10 matches the curvature of the casting billet 9 and the spray angle of the water nozzle 10 .

[0018] The material of the square tube is 2-3 mm thick stainless steel.

[0019] In actual application, the base material of this utility model is a 2-3mm thick stainless steel square tube. Based on the outer arc of 9 meters and the continuous casting billet, it is processed into a certain shape through laser cutting and milling. Water nozzles are installed horizontally at equal intervals. There are three rows of water nozzles in each row, with two water nozzles in each row, that is, eight water nozzles in each row on each of the four sides. This achieves uniform cooling without dead corners on the surface of the billet.

[0020] The single-sided water strips are fixed to the four sides of the lower mouth of the crystallizer by two fixing screws. The turbid water inlet at the bottom of the crystallizer enters the water inlet 1 above the four single-sided water strips on the upper flange of the water distribution plate. Water enters the water nozzle installation pipe 3 through the connecting pipe 2 and the square pipe. The water nozzle 10 is a threaded water nozzle, which is threadedly installed with the water nozzle installation pipe 3. Water is continuously sprayed onto all surfaces of the ingot 9 through the water nozzle 10. Among them, 6 single-sided water nozzles 10 are designed, with a total of 24 water nozzles on the four sides. According to the requirements of the water nozzle spray angle and the curvature of the ingot, the length of the water nozzle installation pipe 3 on each side is different to ensure that the water nozzles 10 are evenly distributed on the surface of the ingot, achieving the purpose of continuous and uniform cooling of the high-temperature ingot.
