Abstract
Cross sectional dimensions of an intermediate product of sectional steel are measured in the course of rolling, by simultaneously, horizontally reciprocating, in the direction transverse to a conveyance line of the sectional steel, two laser range finders which are disposed vertically opposite to each other. The method and apparatus are capable of determining, precisely and automatically, a sectional shape of the H-beam in an on-line manner, thereby improving product quality and yield.
