Problems solved by technology
[0002] At present, in domestic high-speed wire and bar rolling mills, most of the water-through cooling of red steel adopts split tubular water-cooling nozzles. Take the water-cooling nozzle of Morgan Company as an example. When the red steel passes through the nozzle, the nozzle sprays cooling water. For the cooling of red steel, when the red steel is in contact with the cooling water, the water vapor and air bubbles generated cannot be released quickly, so that the air bubbles are attached to the surface of the red steel, and the cooling water is isolated from the surface of the red steel, which affects the cooling effect. At the same time, due to the water vapor And air bubbles run up all the time, so that the upper part of the red steel is not cooled well, and the surface is not cooled uniformly, which affects the inner quality of the steel; at the same time, when the red steel is cooled, the tubular inner cavity of the nozzle is filled with water under pressure , the red steel passes through the water at high speed and bears a large resistance to water penetration, which not only reduces the rolling speed, but also tends to cause steel pile accidents. In addition, once the nozzle is worn out, a new nozzle must be replaced as a whole, which consumes precious metals. The cost of materials has increased, and the existing water cooling nozzles are no longer suitable for the requirements of the new rolling process

Embodiment Construction
[0015] from figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 It can be seen from the figure that an open high-efficiency water cooling nozzle is composed of an upper nozzle body 4 and a lower nozzle body 18, and the upper and lower nozzle bodies 4 and 18 form a split cuboid, which is characterized in that the bottom Positioning slots 12 are symmetrically opened on the left and right, so that the nozzle can be quickly and accurately installed on the nozzle seat, and snap-in positioning ears 23 are set on the upper and lower nozzle bodies 4, 18, so that the upper and lower nozzle bodies 4, 18 The positioning is accurate and the connection is simple. In the left part of the upper and lower nozzle bodies 4, 18, drain cavities 13 through which the bottom penetrates are provided at intervals, and front and rear exhaust and cooling grooves 21 are provided on the top of the upper nozzle body 4 corresponding to the drain cavity 13. The exhaust cooling groove 21 communicate...

A water cooled efficient open nozzle for steel rolling apparatus features that the exchangeable split-type antiwear liner with dischange hole, the water sprayer with open cooling cavity, left ring slot and oblique water spraying hole, and the inlet guard are installed in upper and lower water-spraying bodies from left to right. An oblique water-spraying band communicated to right ring slot is arranged between water sprayer and inlet guard. Said left and right ring slots are communicated with water inlet. When red steel passes through the holes of inlet guard, water sprayer and antiwear liner, the water is sprayed to it by a large oblique angle.
