next-generation rolling mill stand FEATURES AND BENEFITS OF THE NEW HYPER UNIVERSAL CROWN-CONTROL MILL FOR HIGHER REDUCTIONS IN COLD ROLLING Primetals Technologies has developed a new Universal Crown-Control Mill (HYPER UCM) that features work rolls with diameters that are 20% to 40% smaller than those used in conventional UCM mills.
Nov 27, 2015· The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.
Combination: A combination rolling mill is a versatile "two-in-one" type of metal rolling mill that permits both 2-HI and 4-HI rolling operations.

Dynamic characteristic analysis of a two-stand reversible cold rolling mill in the startup process was carried out. The delay algorithm of the interstand thickness was proposed. A new method combined with the accelerated secant and the tangent methods was established to solve the simultaneous equations. The thickness and interstand tension transition processes with different static tension ...

Each heavy-plate 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 4-high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
