Abstract
A method and an apparatus are disclosed for equalizing the temperature of hot steel strip traveling from a preliminary rolling mill to a final rolling mill, equalization to be effected both lengthwise and transversely of the steel strip. To achieve this purpose the lateral edge portions of the steel strip are partially covered by heat reflectors which are spaced from and adjustable relative to them.
Claims13
Apparatus for effecting uniform temperature distribution over the width of a hot steel strip during rolling, said strip having a center portion and lateral edge portions and traveling from an initial treating station to a subsequent treating station, comprising means for advancing the hot steel strip in a predetermined path linking said stations;
- and means for partially covering the lateral edge portions of the steel strip;
- said covering means comprising heat reflectors arranged to surround said edge portions laterally at a predetermined distance from said edge portions, and toward the center of said strip by a distance equal to substantially half said predetermined distance;
- said reflectors being configurated to resemble portions of a conical section, and having center points located in the region of said lateral edge portions;
- said portions of conical sections being segments of ellipses, said predetermined distance being equal to the median value of the semi-axes of the ellipses, so that cooling of the edge of the strip is controlled to produce uniform temperature over the total width of the strip.
