Water cooling pipe correction to vertically unsymmetrical heating of blooms in walking-beam reheat furnace

摘要

Apparatus is provided for decreasing temperature differentials within rectangular metal blooms being heated in a furnace. The apparatus includes elongated internally cooled members located above the blooms adjacent an exit end of the furnace. The longitudinal axes of the internally cooled members are parallel to each other and to the longitudinal axes of the blooms, the latter axes being aligned so as to extend transversely with respect to the direction of movement of the blooms from an entry to an exit end of the furnace.
