Industries in the Primary Metal Manufacturing subsector smelt and/or refine ferrous and nonferrous metals from ore, pig or scrap, using electrometallurgical and other process metallurgical techniques. Establishments in this subsector also manufacture metal alloys and superalloys by introducing other chemical elements to pure metals. The output of smelting and refining, usually in ingot form, is used in rolling, drawing, and extruding operations to make sheet, strip, bar, rod, or wire, and in molten form to make castings and other basic metal products.
Primary manufacturing of ferrous and nonferrous metals begins with ore or concentrate as the primary input. Establishments manufacturing primary metals from ore and/or concentrate remain classified in the primary smelting, primary refining, or iron and steel mill, industries regardless of the form of their output. Establishments primarily engaged in secondary smelting and/or secondary refining recover ferrous and nonferrous metals from scrap and/or dross. The output of the secondary smelting and/or secondary refining industries is limited to shapes, such as ingot or billet, that will be further processed. Recovery of metals from scrap often occurs in establishments that are primarily engaged in activities, such as rolling, drawing, extruding, or similar processes. Most of these processes are energy inefficient. The largest users of energy in this market are compressors, blowers and fans. As the prime movers are operated outside their rated operation parameters they become less efficient. Turbo Trac offers an Infinitely Variable Transmission (IVT) that increases the system efficiency and reduces energy consumption up to 25% on various process applications within the primary metals industry. Additionally the IVT system has variable speed control within the unit, therefore there is no need to use unreliable variable speed drives. Some of the applications within the metals production market that could use the IVT are as follows:
Rolling Mill
Fluid Transfer Pumps
Cooling Water Pumps
