Abstract

Methods and apparatus are provided for determining the longitudinal and transverse distance required between points of support for a freshly cast strand of steel, so that the hardened outer shell is maintained intact until such time as the thermal compressive stress on the shell exceeds the tensile stress caused by the ferrostatic pressure of the liquid core. The methods and apparatus herein reduce to a minimum, not only the distance between the points of support and the number of points, but also the extent of support required between the point of initial support and the point where support is no longer required.
