Used the influence of technological factors of the rolling process on the intensity of the rolling out of the defect to determine the value of deformation and the coefficient of use of the plasticity resource. Introduced the notion of residual coefficient of plasticity resource in the second stage of transformation of the defect. Found that the causes of deterioration of the quality of cold-rolled sheet can be numerous defects of mechanical origin, caused by mechanical damage of the sheet surface. Conducted an analysis of profiles rolling modes, rolled on the mill 1700. With the use of existing methods calculated DUPR on workshop modes of rolling of specified profiles with and without considering the surface defects. Carried an optimization of the modes of strip rolling with surface defects.

“…Технология производства бесшовных горячекатаных труб на ТПА с непрерывными станами для борьбы с окалиной предусматривает использование смазочно-дезоксидирующего материала, далее (СДМ), а также оборудования для их нанесения [1][2][3][4][5][6][7][8][9][10][11][12]. Недостаточное количество СДМ на внутренней поверхности гильзы приводит к снижению качества внутренней поверхности готовых труб, а также к неравномерному износу оправок непрерывных станов.…”

The most important task of increasing pipe production efficiency is the task of improving the quality of manufactured products. Further development and improvement of pipe manufacturing technology is connected with studying the conditions of contact interaction in the pair “tool – deformed metal”, in particular with creation of separating layer. Application of modern lubricant-deoxidizing materials (hereinafter deoxidant) and modern equipment for their application allows to achieve guaranteed separation of contact surfaces. Also creating of separating layer provides significant advantage in terms of improving the quality of finished tubes, operational reliability of finished products, reducing the cost of production and intensification of deformation processes. However, the uneven distribution of the deoxidant on the inner surface of the sleeve leads to a decrease in the quality of the inner surface of the finished tube, as well as to the uneven wear of the mandrels of continuous mills. One of the reasons for lack of guaranteed separation of contact surfaces is mismatch of blown out portion of deoxidant with the set value. The article describes the principle of operation of standard cyclones and calculates the standard cyclone design. The results of computer simulation of a cyclone of standard design and a modernized cyclone are presented. Also presented the results of physical experiments on particle capture.
