Feb 24, 2017· The material of Sendzimir work roll is tool steel, die steel and highspeed 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 6063HRC, 6164 HRC, 6366HRC etc, for different work rolls.
Jun 19, 2018· High Efficiency Milling. High Efficiency Milling can be a very effective machining technique in stainless steels if the correct tools are selected. Chipbreaker roughers would make an excellent choice, in either 5 or 7 flute styles, while standard 57 flute, variable pitch end mills can also perform well in HEM toolpaths.. HEV5. Helical Solutions offers the HEV5 end mill, which is an ...

Working Mill Rolls Forged mill rolls are the important spare parts in the cold rolling line. As forged mill rolls bear big rolling force andinstantaneous high temperature for welding line, slag inclusion and edge crack, forged mill rolls must have good strength, good wear resistance, heat impact strength, and good fracture toughness. We uses electroslag remelting process to keep forged raw ...
Work roll body length depends on the width of strip, sheet and band. Work rolls are usually used as drive rolls. In mill stands where ratio of body length to roll Ø ≥ 5:1, and a very thin alloy steel strip is rolled, and in multiroll machines backup rolls are used as drive rolls. .
