For the alloys listed in, this practice is an alternate process to solution heat treatment in a furnace, such as specified in Practice B 918 as the preliminary step for the attainment of T651-type tempers (see ANSI H35.1). 1.2 This practice applies only to hot rolling mill solution heat treatment of plate for the listed aluminum alloys.
DetailsRolls used in rolling mills are of various sizes and geometries. Rolls used for rolling undergo extreme operating conditions during the rolling process. These conditions include tremendous forces, bending moments, thermal stresses and wear. Roll materials are selected for strength, rigidity, and wear resistance.
Detailsfinishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".
DetailsThis is the starting point of the hot rolling mill practice. Reheating Furnace x Cold stocks are heated to make them soft and thus suitable for rolling. x Furnace has three parts: walls, roof and hearth. Furnace is lined with several layers of refractory bricks.

DetailsWhen using a rolling mill, consider the following best practice hints and tips: Always use dry metal – any dampness will leave marks on the rollers and risk pitting. Roll metal gradually as too much pressure may result in the piece cracking when next annealing.

DetailsA significant step forward is represented by the "integrated Minimills" (DRI plants, EAFs, CCMs and rolling mills, all connected through a continuous energy-saving process, by a compact layout) that Danieli started supplying since 2006. This solution is particularly advantageous where scrap is not available and/or low-cost gas is available.

Detailshot-rolled strip in the finishing mill of an ESP line. Referred to as "ultra-thin rolling control," the system is essentially an adapted control concept that has been successfully applied many times in tandem cold mills. When rolling below a certain strip thickness, the control mode is switched from speed control

DetailsThe rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.

DetailsA mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
