The Main Factors Causing the Crack of Sendzimir Roll The crack of the Sendzimir roll occurs at the transition point from the Sendzimir work roll body to the upper roll neck, within 40-100mm from the upper end of the Sendzimir work roll body. Most of the roll neck cracks are transverse cracks, with two forms of ring cracks and local cracks.
