Abstract
Most national companies are seeking to reduce costs, improve technological processes and increase profitability. The steel industry is no exception - an example of cost reduction is a technology of sorbitized wire rod production. This technology can improve the performance characteristics of wore rod and reduce the number of patenting stages during metalware production. The developed technology has been tested in the CIS countries Stelmor lines, and its task is to eliminate the significant disadvantages of these lines: the absence of differential cooling on the conveyor width, insufficient cooling rate of air cooling sections, the lack of frequency regulated speed control for electric motors. Eliminating these disadvantages and developing new cooling modes using the software, based on the original mathematical model, allows for the production of sorbitized wire rod with high performance characteristics, provided with increased level of pearlite dispersion (1-2 points for at least 85% of area). Each intense and retarded cooling section has to be fitted with adjustable flaps controlled by electric motors, ensuring the alignment rod temperature at the roller conveyor width. Before the start of the reconstruction of the cooling line a detailed technical and technological audit is required to identify and eliminate the causes that lead to uncontrolled temperature deviations or wire rod laying deviations on the cooling conveyor.
