Документ Моделирование напряженно-деформированного состояния элементов кассет с неприводными вертикальными валками для чистовых клетей сортовых станов(НТУ "ХПИ", 2013) Медведев, В. С.; Базарова, Е. В.; Чичкан, А. А.; Шпаков, В. А.An analysis of the results of mathematical modeling of the stress-strain state (SSS) of the cassette with the non-driven rolls of the finishing stands 580 600 mill conducted through the use of the apparatus of finite elements method and option deformation model of metal strength. The influence of changes in the diameter of not power-driven vertical rolls and temperature rolled strip on VAT cassettes. It is noted that the strength characteristics of the cartridge design satisfies the condition of strength. However, in real working conditions is not sufficient rigidity cartridge in a horizontal plane, which leads to the crown of the end-product rolling. The result of simulation of VAT elements cassette developed measures for its modernization.Документ Повышение качества толстых листов за счёт применения шевронного ножа новой конструкции(НТУ "ХПИ", 2013) Боровик, П. В.; Селезнёв, М. Е.The article describes a new design of the chevron knife for cross-cutting of thick sheets. On the basis of the results of the finite elements modeling has been performed a comparative analysis of the quality of the sheet for the cases of cross-cutting of chevron knives of classical and the proposed design. As an indicator was taken the maximum deviation from flatness. Also it was received an expression for determining this value, depending on the width of the sheet and the tensile strength of material when the new chevron design knife is using.Документ О некоторых вопросах разработки и применения валков профилегибочных станов с раздельным вращением формующих элементов(НТУ "ХПИ", 2013) Ахлестин, А. В.The analysis of the existing design rolls with separate rotation forming elements. The basic problems associated with the design of such rolls and their using in production of roll-formed sections with decorative-protective coating. Practical recommendations aimed at improving the design of rolls tool and increase the efficiency of its use by eliminating the relative sliding in calibers rolls.
