Smolyakova V. Improvement of technologies and equipment for hot rolling processes of angle bars in the finishing working stand of section rolling mills

Technologies and equipment for hot rolling of angle bars. Broadening of assortment, improvement of quality and providing economy of material resources during hot rolling angle bars. Research methods and apparatus - mathematical modeling based on numerical recurrent solution finite-difference form of the energy expenses balance clause of the limited elementary volumes, which includes methods of the elasticity and plasticity theory, experiments in laboratory and industrial conditions. Theoretical and practical results - methods of computer-aided calculation and design, recommendations to improve the technology and equipment. Novelty - establishing and clarifying influence of factors on energy-power characteristics of process and quality parameters of angle bars. Implementation degree - have developed new and improved existing technology and equipment, optimal technological modes and equipment parameters of section rolling mills have determined. Scope of use - enterprises of metallurgical and machine-building branch.
