J&L SPECIALTY PRODUCTS COMPLETES CASTER UPGRADE

 PITTSBURGH, Sept. 17 /PRNewswire/ -- The continuous slab caster at J&L Specialty Products Corporation's Midland, Pa., plant resumed production on Sept. 16, following completion of a $10 million upgrade, it was announced today.
 During a 25-day outage, a new high-frequency/short stroke mold oscillator was installed, which will yield important surface quality improvements to the stainless slabs produced on the caster. Prior to the outage, a test stand was fabricated and erected adjacent to the caster to hold the quick-change oscillator assembly which includes the mold, the first segment of the roller apron and the oscillation equipment. The quick-change unit can be removed from the casting machine in approximately one hour. The test stand will be used to simulate actual operation of the oscillator unit and as a diagnostic tool to make final alignment checks and adjustments to the mold and the first segment of the roller apron.
 The caster's slab width capacity was increased to 62 inches through the installation of new on-line width-adjustable molds. The variable width mold will permit slab width adjustments without interrupting the casting process. The wider slabs will be utilized when the company's finishing units are modified for the production of 60-inch-wide cold rolled sheets.
 At J&L's Midland plant, ladles carrying approximately 125 tons of molten stainless steel are delivered from the plant's melt shop to the caster. The molten steel is teemed from the ladle into a tundish and from there into the mold which defines the width and thickness of the finished slab. The chilling process, which will transform the molten steel into a solid stainless slab, begins in the mold and continues as the slab moves in the continuous process down through the caster roller apron to the torch cut-off. The torch cuts the steel into 25- to 30-foot-long slabs that weigh approximately 15 tons.
 From its general office in Pittsburgh, J&L operates stainless steelmaking and finishing plants in Detroit; Louisville, Ohio; and Midland.
