Aluminium Rolling Lubrication: part 1 - Innoval

Aluminium rolling lubrication: Hot Rolling. View of a typical hot rolling mill showing lubricant application. During the hot rolling process, lubrication and thermal control of the work rolls are achieved by spraying oil-in-water emulsions onto the rolls in controlled patterns. The emulsion also removes any loose debris from the roll bite area and carries it to the filter where it is removed

Application of Hot Rolling Lubrication on a Reversing Coil

In the application of roll lubri--ing hot rolling mills, several con-cerns arise, i.e., bite and roll slippage and effectiveness. This paper studies the mechanism of roll lubrication of the reversing hot rolling mill theoretically and investigates the effect of the roll lubrication on mill separating force, torque, and backup roll

Roll Bite Lubrication. - Quaker Chemical Corporation

Hot Rolling Oils Specialty Greases Surface Treatments Temper Fluids Tin Plating APPLICATION Roll Bite lubrication is the application of a dispersion, which is a mechanical mixture of oil (<0.5%) and water (>99.5%) in the hot rolling process. The typical application involves 0.02 to 0.06 gallons per minute at 5 psi per mill stand, about a third of an 8 oz. coffee cup per bar. Oil is injected

Rolling of steel in Hot Strip Mill – IspatGuru

Hot strip mills in these days are either conventional hot strip mills or strip mills for rolling thin slabs. The primary function of the conventional hot strip mill (HSM) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling

High-speed rolling by hybrid-lubrication system

Lubrication systems for tandem cold rolling mills are mainly classified as either recirculation systems or direct application systems, as shown in Fig. 1.The differences were described by Semoto and Okamoto (1992) with the historical background. Recirculation systems are mainly applied to sheet gauge products, while direct application systems are mainly used in high speed rolling mills for

Steel Plant Lubrication - Machinery Lubrication

Circulating oils are used for the lubrication of back up rolls, NTM work rolls of rolling mills. Inhibited type highly refined (Group II base) are used for the turbines and blowers of steel plants. These oils are fortified with antioxidant, antirust, antifoam additives and possess very high thermal stability with, oxidation stability etc. Industrial gear oils are highly refined mineral oils

Rolling (metalworking) - Wikipedia

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to

Rolling mill air-oil automatic lubrication - Dropsa

In Rolling Mill applications, bearing temperatures are lower than casting applications, but rotation speed tend to be higher. One system design characteristics is that the lubrication system has to cover a greater length due to the length of a roller section of a plant. For this reason, lubrication systems tend to be designed in a mixed fashion – a dual line system is used to cover the

What are Lubrication Methods of Steel Rolling

The basic methods of steel rolling mills lubrication are thin oil lubrication, dry oil lubrication, and oil mist lubrication. Thin-oil lubrication uses mineral oil (liquid lubricant) as a lubricant. Because the thin oil has the characteristics of fluidity, adhesion to the metal surface, certain viscosity and heat capacity, it can adhere to the surface of the lubricated part and can form fluid
