Manufacturing of mass-scale products from structural microalloyed steels in integrated production lines

Adamczyk J.

Journal of Achievements in Materials and Manufacturing Engineering

2007

Vol. 20, nr 1-2

399-402

Purpose: Technical-economic aspects of the introduction of integrated technological lines for the production of metallurgical products are presented in the work. They have a special importance for microalloyed steels used in different branches of the industry. Design/methodology/approach: The analysis was carried out on a basis of requirements concerning hot-working of microalloyed steels with high mechanical properties produced by the use of the controlled rolling and thermo-mechanical processing. Findings: A modification of some well-known integrated lines consisting in the introduction of the cooling machine between roughing and finishing trains, instead of reheating machine gives a possibility to realize a controlled rolling. Moreover, using retention shields makes possible to manufacture the products by the thermo-mechanical processing. Research limitations/implications: There is a necessity to adjust technological parameters to precise controlling a course of material processes. Practical implications: Development of demands concerning integrated lines enabling to realize the controlled rolling and thermo-mechanical processing. Originality/value: Manufacturing mass-scale products from microalloyed steels in integrated energy-saving lines.
