Abstract
Abstract
The paper presents a modification of the slitting pass system, which ensured a reduction in roll wear during three-strand rolling of ribbed bars with a diameter of 16 mm, and thus reduced the associated costs. The theoretical and experimental research on the rolling process of ribbed bars with a diameter of 16 mm rolled in three-strand technology was carried out on a D350 18-stand continuous bar rolling mill conditions. To determine the cost of slitting pass wear, the results of numerical calculations of the frictional force unit of work obtained using the Forge2011® computer program was used, as well as empirical calculations.
