Abstract
A method for cooling samples of hot rolled steel sections. A programmable controller directs a predetermined sequence of air and cooling water sprays against the sample while held in a closed container. The controlled cooling of the sample prevents dimensional distortion of the sample so that accurate measurements of the finished hot rolled steel section can be determined.
