ABSTRACT:
A refractory lined electric arc furnace has a hearth, sidewalls and an arched roof. Skewback refractories are disposed between the roof and the sidewalls and are pivotally coupled to vertical support posts which bear against the sidewalls so that the skewbacks may change their angular relation to the sidewalls without inducing undue stresses in the roof as the lower ends of the side walls move inwardly and outwardly as the result of unequal expansion of the hearth relative to the roof.
