Energy-Saving Technology for the Manufacture of High-Strength Threaded Fasteners

详细

An energy-saving technology is proposed for the manufacture of high-strength fasteners (strength class no less than 8.8) on the basis of the principles adopted in thermal–mechanical–thermal technology (TMT technology). This technology is tested in industrial conditions. The technology relies on cumulative increase in the strength at all stages of production: wire rod → blank → fastener. The proposed technology decreases the energy consumption in the manufacture of high-strength fasteners and so increases their competitiveness in the global marketplace.
