Abstract

The utility model discloses an open type effective water cooling sprout which belongs to rolled steel device. Wherein, split type wear strips with discharge holes open on it, a water spraying machine and an entrance guide capable of replacing according to requirements are arranged inside the upper and lower sprout bodies from left to right. An intercommunicated open type cooling hollow chamber, a left ring groove and an inclined water spraying hole are equipped on the water spraying machine with an inclined water spraying strip communicated with the right ring groove provided between the water spraying machine and the entrance guide. When red steels passes through the holes of ware strips by the entrance guide and the water spraying machine, cooling water enters the water holes through the left and right ring grooves and sprays water to cool the red steels with big inclined degree from the water spraying holes and the water spraying strip. The cooled water quickly removes heat, steam and gas bubbles from the cooling hollow chamber under the action of opposite moving force of the two set of spraying water and the residual water and steam will be discharged through discharge holes, which improves the cooling effect and the quality, resolves the water passing resistance of the red steel, saves cost and increases efficiency.

Description

Opening high-efficient water-cooling nozzle

Technical field

The utility model belongs to steel rolling equipment, and what relate to especially that a kind of high line and rolling bar use wears the water cooling part.

Background technology

Existing domestic high-speed rod and bar mill, its red steel wear water cooling, most of dissection type tubular water cooling jet that adopts, water-cooling nozzle with J. P. Morgan ﹠ Co. is an example, hot steel is when nozzle interior is passed through, the nozzle ejection cooling water cools off red steel, and the moment that red steel contacts with cooling water, the water vapour of generation and bubble can not discharge rapidly, make bubble be attached to red steel surface, cooling water and red steel surface isolate, and have influenced cooling effect, simultaneously, because water vapour and bubble up run all the time, just make the top cooling of red steel bad, surface cool is inhomogeneous, has influenced the inherent quality of steel; Simultaneously, when red steel is cooled off, be full of the water of band pressure in the tubular intracavity of nozzle, red steel is worn water at a high speed and mistake, bear the bigger water resistance of wearing, not only reduced mill speed, and be easy to generate heap steel accident, in addition, in case nozzle wear, will new nozzle of integral replacing, not only consume the precious metal material but also increased cost, existing water-cooling nozzle has not fitted into the requirement of new rolling mill practice.

Summary of the invention
