The company said its facility will increase its OCTG heat-treat
capacity by an additional 100,000 tons per year.
Capital expenditures at the Iroquois Falls plant will cost $7 million, says Tyrvainen, and they will encompass manufacturing and installing the three heat-treat
cooking units, infrastructure for milling and planing, raw materials for inventory, and startup capital.
Additional continuous heat-treat
capabilities provide the flexibility to create more customized steels to serve energy and other markets that have a strong long term outlook.
As Brian Sheehy, manager, heat-treat
applications, Airco Industrial Gases Div, Murray Hill, NJ, explains, "Endothermic generators have been around since WWII, a very complicated piece of machinery, running at high temperature, with lots of moving parts such as pumps and valves with limited life.
With the MADI material, we use a special chemical composition and heat-treat
cycles that produce a unique microstructure more favorable to normal, less costly machining methods.
The melt, shakeout and heat-treat
areas of the foundry are the only parts of the facility not air-conditioned.
