Shur-Lock a Sure Success for Republic Technologies International

Located in Lackawanna, NY, Republic Technologies International (RTI) is a 22 stand Birdsboro mill rolling .633” to 3.500” SBQ rounds and hexes covering a wide variety of grades. “SinterMet’s Shur-Lock roll is the only product that RTI considered for their manufacturing process,” says Bill Posey, regional sales manager at SinterMet. Additionally, RTI purchased a complement of trial SMETiC 2000 guide rolls.

RTI commissioned three sets of SinterMet’s Shur-Lock rolls: One set of leader rolls for .633” to 1.063” rounds; and two sets of finishing for the same product. Each set of rolls contains various groove profiles that encompass the variety of product sizes.

Part of the reason RTI depends on SinterMet’s rolls is the experience and customer service that has long been a strength of SinterMet. “Each time a mill is down because of a pass or roll change, money is lost,” explains Bill. “Our SM-62 grade tungsten carbide rolls not only provide RTI with a measurable decrease in cost per ton rolled, but also increased bar quality combined with the ability to roll to tighter tolerances.” With a current capacity of 425,000 tons per year and the desire to roll higher tonnages, RTI requires rolls combining optimum wear resistance with high toughness.

RTI has already achieved five times wear over nodular iron rolls at the initial installation with virtually no pass wear. “As a precaution, we always recommend the initial installation be handled conservatively,” says Bill. It is expected that at the next installation, RTI will realize an even greater improvement versus iron rolls.

“Having SinterMet located a couple hours away is very convenient and adds to their responsiveness,” says Bob Heckl, Roll Shop Supervisor at RTI. “My colleagues had success with SinterMet when they worked with them in the past, and recommended them for our mill,” Bob adds. “I’m confident that we’ll continue to have out-standing performance from both SinterMet and their Shur-Lock rolls.”
