We are the professional manufacturer of rolling mill rolls, including in the bar rolling mill rolls, wire-rod mill rolls, section mill rolls, strip rolling mill rolls, plate mill rolls H beam universal mill rolls, etc.
There are various methods for classifying rolls, which are:
(1) There are steel strip rolls, profile steel rolls, wire rolls, etc., according to the type of product;
(2) There are roll blanks, rough rolls, finishing rolls, according to the position of the rolls in the rolling mill series;
(3) According to the roll function, there are broken scale rolls, perforated rolls, leveling rolls, etc.;
(4) Roll rolls are divided into steel rolls, cast iron rolls, hard alloy rolls, ceramic rolls, etc.;
(5)According to press manufacturing methods include casting rolls, forging rolls, surfacing rolls, nested rolls, etc.;
(6) Hot rolled rolls and cold rolled rolls are classified according to the state of rolled steel materials.

Note: The composite roll neck material is selected according to the strength requirements.
Therefore, different types of rolling mills have different requirements for rolling mill rolls. For example, billets and slab bloomer rolls must have good torsional and bending strength, toughness, and bite in, hot crack resistance, thermal shock resistance, and abrasion resistance. And finishing mill stands require high hardness, resistance to indentation, wear resistance, spalling, and thermal cracking resistance on the rolling mill roll surface.
Understanding the use conditions of the rollers and the failure modes of the rollers used in the same type of mill, as well as the current performance and manufacturing processes of the various roller materials, can correctly formulate the technical conditions of the roller for the rolling mill and select a suitable and economical roller material.
