Liquid Metal flows through a shroud into a trough called a tundish at a rate of five tons per minute nozzles in the bottom of the tundish directs the Metal into water-cooled moulds as the Metal flows into the molds it begins to solidify still soft the Metal is gently directed by the curved radius of the caster to a horizontal Metal Corner Brackets position at the run-out table from molten Metal slabs emerge glowing from an internal temperature of nearly 2,000 degrees automatic torches embrace the slabs burning through the Metal which is now nine inches thick a tag is attached to record the slabs identity as the Metal is processed into the customer’s order still about 1,200 degrees the slabs are cool enough to load on rail cars for their journey to the hot strip mill more than 30 feet long each slab weighs nearly 90,000 pounds with enough energy to heat a city the slabs are bathed in a glowing furnace for three hours shielded from the 2400 degree heat of the slab an operator sends the monolith toward its destination more than half a mile away.

The slabs glow and unmistakable footsteps down the row line are familiar science at the hot strip in six minutes this 40-ton behemoth will make the most awesome transformation in Metalmaking as more than 130 thousand horsepower press it as thin as a computer disk the bar is squeezed between the huge roughing mill rolls like so much clay blasts of water break away the thin crusts of scale that formed on the slab during heating sending up a rooster tail of spray the hot Metal yields to the relentless hydraulic pressure in the only manner it can halfway to its destination its nine-inch girth has been trimmed to a mere inch and a half the rest of its mass now trails along more than a hundred feet behind its front edge linked by a host of computers and radios operators at the hot strip monitor Outdoor Screws every facet of the process some of the most advanced technology in the world controls the seven finishing stands of the hot strip mill only several feet apart.
These massive rolls give the strip its final thickness and shape as the seal passes through each stand its thickness is reduced further by the time the front edge of the strip clears the final stand it may be travelling more than 25 miles per hour a half-mile from its blistering-hot start a cold spray cools the Metal as it speeds toward the coil errs these marvels of timing catch the speeding strip and wind it into a coil from glowing slab to glistening strip what was minutes ago a mere 30 feet long this coil would now span a dozen football feet but the journey for this aka seal is far from over this hot-rolled coil now has the fundamental strengths of seal to meet the sophisticated requirements of many a case Metal customers these green coils as they are called will be further processed.
