Description
(54) ВАЛОК СЛЯБИНГА(54) Slab Roller
в данном случае 50% длины бочки валка). Максимальное же рассто ние между калибрами определ етс максимальиой шириной прокатываемых сл бов, котора в предельном случае чуть меньше длины бочки. Исход из этого, максимальное удаление от середины вертикальной оси валка , где следует располагать калибр, составл ет 45% длины бочки валка.in this case, 50% of the length of the roll barrel). The maximum distance between gauges is determined by the maximum width of the rolled slabs, which in the limiting case is slightly less than the length of the barrel. Based on this, the maximum distance from the center of the vertical axis of the roll where the caliber should be positioned is 45% of the length of the roll barrel.
Оиределеиную роль играет глубина калибров , котора обуславливаетс услови ми сминани приливов иод действием веса сл ба (минимальна глубина калибров), а также услови ми образовани закатов в местах расположени приливов при прокатке сл ба в лист (максимальна глубина калибра). При слишком большой высоте формируемого прилива на сл бе (более, чем 4% от диаметра бочки) на листе остаютс закаты. Мала же высота приливов (менее, чем 2% от диаметра бочки) не всегда обеспечивает отсутствие контакта сл ба с глиссажнымй трубами, т. е. под действием веса сл ба приливы сминаютс .The depth of caliber plays a certain role, which is caused by the conditions of tidal crushing iodine due to the weight of the slab (the minimum depth of the caliber), as well as the conditions for the formation of sunsets at the locations of the tides when rolling the slab into the sheet (the maximum depth of the caliber). If the height of the formed tide is too high (more than 4% of the barrel diameter), sunsets remain on the sheet. However, the low tide height (less than 2% of the barrel diameter) does not always ensure that the slab does not come into contact with the sliding pipes, i.e., under the influence of the weight of the slab, the tides are crushed.
Пример. Длина бочки валка 1700 мм.Example. The length of the roll barrel is 1700 mm.
Диаметр бочки валка 1350 мм. Рассто ние от середины его вертикальной оси до ручьев 500 мм (20,4% длины бочки валка). Глубина ручьев 40 мм (3% от диаметра бочки валка).The diameter of the roll barrel is 1350 mm. The distance from the middle of its vertical axis to the streams is 500 mm (20.4% of the length of the roll barrel). The depth of the streams is 40 mm (3% of the diameter of the roll barrel).
Наличие ручьев на нижнем валке сл бинга позвол ет при прокатке полученных сл бов на лист уменьшить разнотолщинность листов и тем самым повысить их качество .The presence of streams on the lower roll of the slabing allows for rolling the resulting slabs on a sheet to reduce the thickness variation of the sheets and thereby improve their quality.
