Casting Rolling Mills

Casting Rolling Mills

A continuous casting rolling mill is a specific mill that is used for the process of taking molten steel and solidifying it into a “semi-finished” billet, bloom, or slab for subsequent rolling in the finishing mills.

Casting re-melts the alloyed material and converts the alloy while in the liquid state to a cast strip or rod. Alloys are often preferred over single element metals, particularly for solder preforms, because of their different melting points, specific conductivity attributes or improved thermal expansion values.

The casting process requires a starting bar for the liquidus metal to cling to; once the starting bar is in place, it slowly draws the liquidus metal through a die to form cast strip or rod with the proper cross sectional dimensions. The result is a uniform bar or rod ready for subsequent processing. Prior to the introduction of Continuous Casting in the 1950s, steel was poured into stationary molds to form “ingots”. Since then, “continuous casting” has evolved to achieve improved yield, quality, productivity and cost efficiency.

The casting process is comprised of the following sections:

*A tundish, located above the mold to feed liquid steel to the mold at a regulated rate
*A primary cooling zone or water-cooled copper mold through which the steel is fed from the tundish, to
generate a solidified outer shell sufficiently strong enough to maintain the strand shape as it passes into the
secondary cooling zone
*A secondary cooling zone in association with a containment section positioned below the mold, through which
the still mostly-liquid strand passes and is sprayed with water or water and air to further solidify the strand
*A severing unit (cutting torch or mechanical shears) to cut the solidified strand into pieces for removal and
further processing

We are able to work with your needs to fully integrate the casting rolling mill directly into your line to provide processing of cast strip to coil.  Typically, that line would consist of the casting mill, temper pass mill, flying shear and coiling equipment for take-up of the finished product.
