Baosteel Group Changzhou Roll Manufacture Company

Sendzimir mill is favored by high technology customers because of high rolling precision ,such as  very thin strip and difficult deformation silicon steel, stainless steel.

The material of Sendzimir work roll is tool steel, die steel and high-speed steel. These are materials of high hardness . The rolls are manufactured under quenching and tempering processes of high temperature . During the tempering process, secondary hardening is used to reach hardness of  60-63HRC, 61-64 HRC, 63-66HRC etc, for different work rolls .

High hardness tool steel and die steel are used as raw materials for Sendzimir intermediate roll. The rolls are also manufactured under quenching and tempering process of high temperature. During tempering process, secondary hardening is used to reach hardness of  55-60HRC for different  intermediate rolls.
