Rolling Mill Roll

Mill Roll is an important part of the rolling mill in a steel rolling mill, using a pair or a group of rolls to roll the pressure generated when rolling steel. It mainly withstands the dynamic and static load of rolling, wear and temperature changes.

Roll is to make (rolling material) metal plastic deformation tool, is to determine the efficiency of the mill and the quality of rolling material important consumption parts. Roll is an important part of the rolling mill plant rolling mill, the use of a pair or a group of rolls rolling pressure to roll steel. It is mainly subjected to dynamic and static loads during rolling, wear and temperature changes.

There are many types of rolls, according to the type of rolling mill rolls can be divided into the following three categories.

(1) Flat rolls, that is, strip mill rolls, the roll body is cylindrical. General hot rolling steel mill rolls made of slightly concave, heat expansion, you can get a better plate shape; cold-rolled steel mill rolls made of slightly convex, when rolling, the rolls produce bending to get a good plate shape.

(2) Grooved rolls It is used for rolling large, medium and small sections of steel, wire rod and primary rolling open billets. There are grooves engraved on the roll surface to make the rolled parts form.

(3) Special rolls It is used for steel pipe rolling mill, wheel rolling mill, steel ball rolling mill and perforating machine and other special mills. This mill rolls have a variety of different shapes, such as steel rolling with the principle of oblique rolling rolls have conical, drum-shaped or disc-shaped.
