Low-temperature coiling in the Stelmor line (∼850°C) is best for chemical scale removal. In that case, thin, dense scale is formed, without peeling, spots, or blisters. For low-carbon wire rod, the plasticity declines monotonically, while the strength increases. For high-carbon wire rod, the microstructure is unsatisfactory: tempering sorbite and also bainite and pearlite of reduced dispersity. (The optimum scale consists of wustite.) With increase in coiling temperature (950-1000°C), mechanical scale removal is best, on account of the difference in thermal expansion of the scale and the metal. In storage and prolonged transportation, blisters and scale-free sections may lead to corrosion and, on etching, to overetching of the metal. © 2013 Allerton Press, Inc.

The introduction of high-carbon wire-rod production at OAO Moldavskii Metallurgicheskii Zavod is considered, with particular attention to wire rod for the production of metal cord. The influence of various factors-the chemical composition of the steel, its content of nonmetallic inclusions, its macrostructure and microstructure, decarburization, surface defects, and the scale-on wire rod performance is considered, individually and in aggregate. An effective production technology is developed, including steel production, ladle treatment, casting, rolling, and thermomechanical treatment of the wire rod for metal-cord production. © 2010 Allerton Press, Inc.

Improvement in the microstructure and performance of wire rod for the production of high-strength reinforcing cord is considered, To suppress undesirable structures (structure-free cementite and martensite), the use of high-carbon steel microalloyed with vanadium and/or chromium is recommended, as well as thermomechanical treatment of the wire rod. © 2010 Allerton Press, Inc.

The development of rolling at OAO Moldavskii Metallurgicheskii Zavod is briefly recounted, with particular attention to the consistent modernization and reconstruction of the equipment and improvement in the rolling technology. New high-quality products have been introduced: thermomechanical reinforcement of strength classes 400-1000 N/mm2; low-carbon wire rod (including alloy steel wire rod) for welding ship hulls, large-diameter pipe, and gas and oil pipelines; and high-carbon wire rod for the manufacture of springs, cable, cord, and reinforcing cable. The design output has been increased by a factor of around 1.8. © 2010 Allerton Press, Inc.

The electrode gaps in the roof of a 120-t arc smelting furnace are sealed gas-dynamically, by the jet-injection principle. Laval nozzles are employed; the refractory dosing units in the intermediate ladle of the continuous-casting machine serve as mixing chambers. © 2010 Allerton Press, Inc.
