DC Electric Arc Furnace Direct current technology, with eccentric bottom
tapping, offers the best available means of making steel. Advantages include lower power
and electrode consumption, longer refractory life, lower maintenance, enhanced stirring
effects and more efficient tapping.
The results are excellent performance and better steel quality. |

|
Ladle Arc Reheating Furnace After further refining the steel, this furnace
provides the steel to the Bloom Caster at the correct temperature, chemistry and time.
Argon stirring, through a porous plug in the bottom of the ladle, promotes the
homogeneous mixing of the additives to the ladle, assists in temperature control, and
enhances the flotation and removal of nonmetallics. |
 |
|
|
Tank Vacuum Degasser Vacuum Degassing reduces the level of hydrogen and
other gases in liquid steel. Argon stirring during the degassing process further reduces
the hydrogen content and enhances steel cleanliness.
Clean steelmaking practices, plus the benefits of the Ladle Furnace and Vacuum
Degasser, mean that the Jumbo Bloom Caster receives steel with the correct chemistry and
excellent cleanliness. Ultimately, this results in improved product performance. |

Continuous Jumbo Bloom Caster The Caster produces Jumbo blooms
measuring 23.6" x 14.6" (344 square inches). A large tundish reservoir promotes further
flotation of nonmetallics, while complete argon shrouding is used to prevent the
reintroduction of harmful gases.
The resultant blooms are world-class in quality the ideal starting material for
rerolling or forging. |

44" Blooming Mill After heat-soaking to the proper temperature, as-cast
blooms can be rolled. Due to their jumbo size, as-cast blooms require many passes which
provide beneficial hot work to reduce them to their final dimension, which can range from
6 in. through 14 in. RCS, or as rectangles 6 in. to 14 in. thick x 6 in. to 24 in. wide. |

|
|
Finishing and Shipping After the blooms have been inspected and conditioned
to customers' needs, identity is confirmed and bar-coded identification tags are applied.
Blooms can be shipped either by rail or truck.
PST is serviced by rail, and is conveniently located near Interstate Highways 81, 83
and 76 (PA Turnpike). |
