primarily used where they have to withstand high loads as in Blooming Mills or in Heavy Section Mills. Forged and hardened rolls are also used as backup rolls in 4 high mills although normally alloy cast steel rolls are used for backup. Iron Base Rolls These are maximum used in rolling mills .
Diameter – depending on the material, ranging from mm to 2 mm for small media mills, up to 1/8" to 1" for traditional Attritors and up to ½" to 2" for ball mills Composition – metallic grinding media like carbon steel, forged steel, stainless steel or chrome steel .
M7 molybdenum highspeed tool steels are mainly used for cutting tools in all machining operations. This steel exhibits good abrasionresistance because of its carbon and vanadium contents. It is an excellent choice for premium tools which require an outstanding balance of red hardness, edge toughness and wearresistance.

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.
Alloy 4750/ High Perm 49® is a 48% nickeliron alloy which combines a high saturation flux density (approx. 16000 gauss / tesla) with high magnetic permeability and low core loss. This alloy has the high saturation flux density of any of the nickeliron alloys, making it a versatile alloy.

Ball mill is also known as ball grinding mill. Ball mill is the key equipment for recrushing after the crushing of the materials.
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 ...
on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H.
