The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
The Severstal facility (formerly Ford Rouge Steel) produces cold rolled steel for use in the automotive industry. The steel rolls are processed and sized using a variety of different roll machines, which require extensive lubrication to meet quality and production requirements.
A hot strip mill rolls cast steel slabs into thin sheets [1,2]. A typical hot strip mill facility is com-posed of the following units: reheat furnace, roughing mill, transfer table, coilbox, crop shear, nishing mill, run-out table, and coiler [3,4]. Bars with thickness of around 250 mm are reheated to a temperature
These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils.
• Hydraulic oil is used in hydraulic presses or clamping systems. Anti-wear additives make these non-detergent oils the best choice for hydraulic systems and equipment. • Slick 50 can be applied to the roll space portion of the mill spindles. It is a synthetic oil-based treatment that protects from friction and heat.
Product Description: Qualtech Products Industry Hydraulic Three Roller Mill is a production grinding machine at industrial scale designed and engineered for milling and wet grinding of a wide range of materials from medium to high viscosity.This professional Hydraulic Three Roller Mill finds its production application in the industrial fields of paints, inks, toners, lubricants ...
SMS SIEMAG Hot Strip Mills 8 The coilbox arranged between the roughing stand and the finishing mill of a hot rolling mill forms coils of transfer bars, thus serving as both material and heat accumulator. During uncoiling, the former trans-fer bar tail runs into the finishing mill as transfer bar head. The coilbox is employed in new facilities ...
cast slabs into plate, the plate into hot rolled coils and the hot rolled coil into cold rolled coil. Many of these old mills are still running today as a result of upgraded electrical and hydraulic systems, including hydraulic screwdowns, hydraulic roll bend, and tension control.
With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oil-lubricated cylindrical roller bearings. The oil is both, lubricant and cooling agent.
These fire resistant hydraulic fluids can also be used in environmentally sensitive hydraulic applications without compromising the overall hydraulic system operation. Applications include: Steel: Slab caster slide gates / hot mill roll force and roll balance / pickle line and welders / cold rolling mill / annealing / tin rolling / automatic ...

Typical upgrades to hot mill stands include the addition of roll bending for profile and shape control as well as the installation of hydraulic roll force systems for automatic gauge control. Customers are also looking to see production improvements by eliminating mill down time through shorter roll changes.
Honeywell's Automatic Gauge Control (AGC) and Hydraulic Gap Control (HGC), incorporated with the MetalsMaster gauging system, enable mills to deliver the right gauge thickness with the least product variation. It also offers Target Adaptive control to increase .
Principle of Four Rolls Rolling Mill. The roll system of four rolls rolling mill consists of two supporting rolls and two working rolls. The pressing force from cylinder or mechanical system will be transmitted through bearing stand, supporting roll, working roll and finally act on the product during operation.
hot-rolled coils, thereby effecting pass cutting in the cold-rolling process. 3) To realize a high-productivity hot-rolling mill by replac-ing the computer control system with one of the latest design that achieved a significant degree of automa-tion.

It may reach easily to 70% and as high as 75 to 80% according to fibre% cane, preparatory index, feeding, mill setting, hydraulic press, proper juice drainage and optimum mill roller speed. With a view to obtain high primary extraction, the first mill should be provided with Donnelly chute, under feed roller and a lotus roller.
the roll gap, or the roll bite) between the work rolls. In this region the metal is plastically deformed, and there is slipping between the strip and the work roll surface. The necessary compression force is applied by hydraulic rams, or in many older mills by a screw arrangement driven by an electric motor [6]. Figure 1.
How hot is too hot? Hydraulic fluid temperatures above 180°F (82°C) damage most seal compounds and accelerate degradation of the oil. While the operation of any hydraulic system at temperatures above 180°F should be avoided, fluid temperature is too high when viscosity falls below the optimum value for the hydraulic system's components.
to-use hydraulic roll mounting and removal system. Stands are installed on a common base with a robust enclosure to contain soluble oil and reduce any environmental impacts. In the event of a cobble the enclosure safely contains rod from escaping into the work area. FIELD OF APPLICATION Non-ferrous long rolling mills MORGAN NO-TWIST MILL STANDS
