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.
• Lowvibration mill running, even in partial load ranges down to 20% of the mill load, thanks to individuallyguided grinding rollers. • The speciallydeveloped hydraulic roller relief system enables grinding of different fuels (both hard and soft) and improves the machine control response.
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.
Danieli is focused on developing and standardizing highquality technology "packages" that are proven to be financially and technically feasible, in terms of the anticipated technological, ecological, and .
Hot Rolled Division Acenta is the largest UK reroller of engineering grade flat and square steel bars. We specialise in producing bars for Bright Drawing in high quality engineering steel grades including carbon, freecutting, leaded freecutting and low alloy grades.
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.
Papermaking . PAPERMACHINE – PRESSING . 1. INTRODUCTION . The paper web formed on the wire part or the forming section passes onto the press section. Pressing of the web on the paper machine follows entering of wet web through the nip of two rolls running under pressure. Under the effect of pressure between the two rolls further water removal of

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 ...
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 oillubricated cylindrical roller bearings. The oil is both, lubricant and cooling agent.
Lubrication in an integrated steel plant is a major challenge with numerous types of lubricants and various types of equipment. The steel plant equipment work under various operating parameters; like from extreme heavy load to very high speed, low temperatures to high temperatures, dusty polluted environment to humid acid environment.
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.
Mar 25, 2015· The hydraulic system of vertical mill is an important system, the main function of the hydraulic system is to break the grinding roller, which is when the internal grinding cavity wear parts wear, can stop open on both sides of the grinding roller mill, to replace the inside parts or repair.
