A progressive roll edge misalignment that can be concave or convex. Observed only after the roll has started to be unwound. Non-uniform cross-deckle caliper: Reduce cross-deckle caliper variation. Winding too soft at same radius of the roll with respect to other radius: Control hardness of wind throughout the problem area.

immersing the file in a quench-ing solution.This combination of heating and cooling under care-fully controlled conditions brings the file to the maximum hard-ness to the very top of the cut-ting edges. Introduction Choosing the right file can be confusing, with so many sizes, shapes and cuts available it is difficult to decide the right one ...

Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls have got deflected by high rolling forces. Elastic deformation of the mill takes place. If stiffer rolls are used, namely roll material of high stiffness or elastic constant, then mill spring can be avoided.

After more than 10 years I visited my hometown's unique narrow strip mill again. Images now at Stahlseite. The rolling mill in Hohenlimburg, now part of the city of Hagen/Germany, was founded in 1846 and goes back to the old Böing forge, a descendant of this family later founded the Boing aircraft company in Seattle, USA.

20 High Cluster Mills utilize small diameter work rolls which allow higher reductions on harder materials than other mill configurations. The multi-roll system having employs a unique roll configuration with adjustment capabilities to control strip shape and compensate for the effects of rolling a wide range of different strip widths to very thin thicknesses.

The intermediate rolling mill is composed of six short stress mills arranged alternately by horizontal and vertical mills without archway. The nominal diameter of the roll is 400 mm, and the length of the roll body is 650 mm. The range of application is 430 mm to 370 mm. There is a crank flying shear at the exit of the medium rolling mill.

The steel plate needs to be quenched by induction hardening machine to increase its hardness and wear resistance. Our round bar induction forging equipment works well for induction hardening of steel plate, as shown in the photo above.. This equipment for steel plate induction hardening has perfect protection features, such as: over-voltage, over-current, water shortage, …

proper roll cooling, the required thermal roll crown can be controlled in way to influence the overall roll profile. It is common practice adjusting the roll cooling to the strip width being rolled. Roll cooling is hence an actuator to allow stable rolling conditions of the mill. This is particular true for strip tandem rolling mills with regard to

Mill roll's quenching depth is usually 3-5mm, and this depth determines that it can only use the equipment for quenching heat treatment. After hardening, the surface of the mill roll has hicker toughness region under the hard layer with good compression of internal stress, so that the anti-fatigue and breaking capacity are higher.
