At the Harrison Steel Plant, we cast steel blooms in our strand caster, designed to produce extremely clean bar products.

A ladle of steel is lifted five stories above the melt shop floor and positioned in a cradle over a large tub called a tundish.  Protected from unwanted gasses in the atmosphere by a shroud of inert gas, the steel is carefully metered out into the tundish.

From there, it flows down into four rectangular, water-cooled molds, electromagnetically stirred as the steel moves.  As the steel begins to solidify, it is pulled down through the molds and out to the runout table.  The strands are straightened and cut into blooms of specialty carbon or alloy steel grades.

We typically cast multiple heats of steel in a sequence, making this a highly efficient process.  The large bloom cross-section ensures a good reduction ratio, with enhanced overall properties in the final steel products.
