It was common practice to use an inductor furnace in rolling lines as evidenced by E2, E3 and E6. Hence it came within routine modification to replace a heating element in the rolling line of E1 by an inductor furnace. Further, it was common practice for a skilled person to place a heating element where needed. ... a rolling mill and a cooling ...

Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to ...
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.

rollable temperature in a reheating furnace. This 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. It is insulated by glass wool.
If the steel mill has rolling equipment, the hot metal may be rolled rather than cast. Slabs, ingots, billets and blooms are often shipped by sea in transit to a rolling mill where they can be rolled into long products such as profiles, beams and channels. Steel slabs are rolled into plate. There are two rolling processes – hot and cold rolling.
through joint efforts with mill builders, new types of rolling mills equipped with such actuators; typical examples of these mills are the 6-high mill with lateral shifting of intermediate rolls (called the HC mill)5) 6)and the pair-crossed roll (PC) mill, which are shown in Fig. 1 (a) and (b), respectively.

However, in hot-rolling mills, water used for descaling and cooling steel (process water) and water used for cooling rolls and bearings (cooling water) were reported together. Inasmuch as the steel indus try generally considers all water used in rolling mills as …
A rolling mill is a machine tool that passes heated or normal-temperature metal through two rolls and transforms it into diverse shapes. A work roll is a core part of a rolling mill that enters into direct contact with rolling material to make cold rolled carbon sheets (CR) of the desired thickness.

Rolling-Mill Practice H. M. FINUCAN University of Queensland, Brisbane, Australia (Received original August 23, 1974; final July 16,1975) In cutting beams or candy or rulers to a specified length, it is often sensible to make a first rough cut comfortably long and then a second exact cut. This certainly applies to the hot-rolling of steel beams ...
