Description And Tech Data. High Speed Steel Rolls. The microstructure consists of tempered bainitic / martensitic matrix with primary and secondary carbides. Primary carbides MC, M 7 C 3, M 6 C and M 2 C are originated during the eutectic solidifiion. Secondary carbides are precipitated during the High Temperature quench and tempering.
Plate Mills are quite literally the most powerful metalworking tools on earth, but they are precision tools too – not just in terms of dimensional control but also in imparting mechanical properties to the rolled product. Accurate microstructural control starts with expert process knowledge. Whether building a new mill or upgrading an existing one, the essence of project success is a quick ...
· 3. Four High Rolling Mills. The mill has four horizontal rolls, two smaller diameters and two much larger. The larger rolls are called backup rolls. The smaller rolls are the working rolls, but if they would be thicker in the centre and thinner at either end.
What are the techniques/criteria to measure the lifetime of chrome plated work rolls and plain work rolls? Valery KNYAZIKHIN Magnitogorsk, Russia . 2002. A. The coating layer is pure chrome so you will increase the hardness to more or less 1000 Hv. Chrome is very fragile and on these kind of rolls a thick layer will break down because of the big forces involved in the mill. 10 to 20 microns ...
It even shows the need for larger diameter backup rolls to support longer, smaller diameter work rolls, Figure 1. 15th – 17th century. In the middle of the fifteenth century small mills produced gold lace, and other decorative work, in soft metals. However, as these techniques became more widely known, demands for products coming from metal rolling increased. There is evidence for rolling of ...
Rolling in the heavy plate mill in Oxelösund. The rolling process The traditional equipment for rolling of heavy plate is the fourhigh mill. This mill has four rolls, two weaker work rolls and two sturdier backup rolls. The work rolls get in touch with rolled material and reduce its thickness. The backup rolls counteract the deflection ...

Each heavyplate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.

A typical four hi mill stand consists of a mechanical screw, AGC capsule, a roll stack consisting of two backup and two work rolls. In the stack, a method must exist to compensate for backup or work roll wear as the rolls transition from new to scrap size. Sometimes this is accomplished by "shimming" at the bottom of the mill to a predetermined height based on various backup and work roll ...
work rolls laterally with respect to centerline of the strip, 3] using shaped rolls – rolls with profiles, 4] Rotation of the axis of the work roll with respect to axis of backup roll in horizontal plane – results in deflection of work roll ends, producing camber. Roll flattening: There is increase in radius of curvature of rolls due to the roll pressure which causes elastic deformation of ...
