Abstract
A cooling strand for cooling small-section steel has individual cooling tubes arranged coaxially in a water trough along the path of travel of the steel sections. Each tube has a constant internal diameter, a diameter to length ratio of from 1:5 to 1:15 and a number of water feed pipes around its circumference at one end. The water feed pipes direct water under pressure into the tubes in a direction opposite to the direction of travel of the steel sections.
Claims4
A cooling strand for cooling small-section steel passing through said strand in a first direction, the strand comprising:
- a water container with water therein;
- a plurality of cooling tubes immersed in said water and arranged coaxially within the water container, each tube having a constant internal diameter and a diameter to length ratio of from 1:5 to 1:15;
- a plurality of pipes being provided at one end of each tube around the circumference thereof for feeding water under pressure into respective tubes in a direction having a component in opposition to said first direction;
- and means for providing a flow of water under pressure through said pipes and for inducing a flow of water through said tubes in opposition to said first direction while said steel is moving through the tubes.
