A sill and door jamb assembly providing an opening in an electric arc furnace, the sill and door jamb assembly having a sill block assembly and two jamb block assemblies. The sill block assembly having side-by-side sill blocks, each of the sill blocks being positioned side-by-side to form the sill block assembly and having an upper end and a lower end. The lower end of the sill block assembly is confined within a plurality of courses of the refractory bricks. Each jamb block assembly having a plurality of jamb blocks positioned side-by-side. Each of the jamb block assemblies having a lower end and an inner surface abutting the distal ends of the sill block assembly. The inner surfaces of the jamb block assemblies and the upper surface of the sill block assembly form the slag opening in the furnace.

Sill and door jamb assembly for electric arc furnace

A lining for a ladle used to handle molten metal. The lining is comprised of a first course of like, refractory bricks arranged horizontally in the ladle, the first course having an upper surface. A second course of like refractory bricks is arranged to spiral within the ladle. The second course is disposed on the first course, and the second course has an upper surface. A starter comprised of at least one refractory component is dimensioned to form a contoured ramp surface. The starter is disposed between the first course and the second course of like refractory bricks. The ramp surface at one end of the starter set is aligned with the upper surface of the first course and the ramp surface at another end is aligned with the upper surface of the second course.
