Drawing dies & cones

The Pos-Himetal project in Gwanyang, South Korea, is under construction where multiple furnaces will be used to produce a refined manganese product. In January last year Tenova Pyromet began design and supply on electrodes, copper bustubes, hydraulics and control systems for their two submerged arc furnaces, and this year, Dongbu Corporation asked Tenova to design and supply a ladle furnace and a slag holding furnace for the project. The slag holding furnace comprises a furnace whose complete shell tilts on a set of rollers. The electrodes are retracted from the furnace when the tilting operation occurs. Tenova Pyromet has supplied furnace equipment for many manganese operations, but this project is unique in the methods and processes used to produce a low phosphorous and low carbon manganese product. The delivery period for the equipment is extremely short, which prompted Tenova Pyromet to make use of the wealth US Synthetic Wire Die manufactures long-lasting polycrystalline diamond (PCD) wire dies, which allows wire mills to pull more pounds of wire per dollar spent on dies. dies, process trouble-shooting, and consistency in wire die geometry. Precise laser-cut geometry (improved entrance, reduction angle, bearing length, bearing diameter) also gives customers fewer wire breaks, less problems setting up a line, and the ability to replace dies with less downtime. The technical expertise in PCD enables development of the unique material used in the wire dies. US Synthetic is the only wire die manufacturer that presses its own PCD inserts. advanced Customers diamond value the long-lasting

Pressing the diamond core and finishing the die to exact specifications offers customers a durable, high- performance product that draws more pounds of wire per dollar. State-of-the-art diamond sintering processes – including proprietary cubic presses that apply nearly 1 million pounds

of uniform pressure and generate temperatures of 1,400°C – are used to synthesise the dies. US SyntheticWire Die – USA Fax : +1 801 235 9141
