Dec 11, 2008· Aluminium Rolling Oil is non-staining, noncorrosive and has good additive solubility for fats and alcohols which are added by the manufacturers of aluminium rolling oil for the advantage of smooth productions. Application / Composition : Aluminium Rolling Oil are recommended for cold rolling of aluminium sheets, strip or foils.
The Dropsa air-oil lubrication system has5-Stand Tandem Cold Mill to lubricate the bearings and seals positioned inside the Working Roll / Intermediate Roll / Back-up Roll chocks. The function is achieved by using Dropsa's SMX progressive dividers, tailor-made splitter tubes, cutting-edge control panel and other components. A lubrication cycle of the system could be simplified as following:
other applications (cold rolling, back up rolls) have similarities in other components. Therefore I hope this book will be useful in giving a general understanding of especially big components - large cross sections - which might suffer from damage for various reasons.
Filtration system for the cooling water at the roll mill. BOLLFILTERs like the aquaBoll ® help to reduce the high maintenance and downtime cost by preventing the spray nozzle blockages of cooling water sytsems..

FOR HOT & COLD ROLLING MILLS BY: HUBERTUS WENIG * ABSTRACT . ... terms of cooling than rolling oil. The viscosity of the coolant has an influence on the spray developments using nozzles. At higher viscosity, which is normally the case with rolling oils, the spray ... applications for special cast-rolling mills for narrow-gauge hot strip production.
Aluminum rolling is an industry that requires process optimization and high-quality end-use products. ExxonMobil Chemical has developed a tailored diluents portfolio to meet the high purity required by aluminum foils and sheet products.
The oil, injected at time intervals, is then propelled by the air stream along the feed line as droplets in a spiral motion to enter a bearing as an oil spray. Mist Supply. Oil mist is an aerosol mixture of very small oil droplets (one to five microns) suspended in air with the appearance of smoke.
Process Lubricants in steel plants include slushing oil, rolling oils, pickler oils, mould oil and wire drawing compounds. Slushing oils are antirust, inhibited, light oil for sheet protection .Rolling oils are made of synthetic oil, semi-synthetic oil, fatty oil which is used for roll bite lubrication .

EDT rolling transfers this exact finish onto the strip during the final rolling pass. Crucial here is a specific roughness on the work rolls created by electric discharged texturing (EDT). Once it is applied to the roll barrel, this roughness transfers precisely onto the strip surface.
Rolling mill- Air/Oil 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.

Estimates of the air pollution resulting from both hot and cold rolling processes were made from data acquired by questionnaires, mill visits, and emission source sampling. Background information pertaining to steel rolling operations, lubrication practices, rolling mill lubricants, and rolling emulsion application technique is also presented.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.
This seminar will give an introduction to the process, equipment and ancillaries utilized to produce long products; the primary focus is on the process and equipment customarily found within the "rolling mill" building, i.e., reheat furnace, rolling mill and finishing end.
Greases help lubricate a range of bearings throughout an integrated hot rolling mill operation, and most applications benefit from a heavy duty grease with high base oil viscosity, high load carrying ability, high temperature performance, excellent water resistance and strong corrosion protection.

Manufacturers across the steel, aluminum and metal fabricating industries depend on spray technology from Spraying Systems Co. for their daily operations. Our spray nozzles, headers, lances and turnkey systems will optimize your operations while conserving water and reducing maintenance.
valuable to this specific tandem mill. The use of cold rolling oil emulsions for maximizing mill production in terms of rolling speeds and metal surface quality has been in practice since the inception of these mills. Many of the original cold rolling oil lubrication systems were designed with direct oil application .
This paper describes induction heating of steel billets in a direct rolling application. It is shown that both the design and operation of the process requires a thermal analysis of the billet from its liquid state to its entry into the rolling mill. The paper outlines the interactions between process units and relates these to .
Aluminium Rolling Lubrication: part 2. It is now accepted that aluminium rolling lubrication strongly influences both mill productivity and metal quality. Following on from our last blog post, we will now introduce you to aluminium rolling lubrication for Cold & Foil Rolling and Water-Based Cold Rolling. Cold & Foil Rolling
Jun 04, 1996· The present invention is an oil applicator and a method for use in applying a thin film of oil uniformly and evenly over a strip of metal, such as in a cold roll mill for metal. The oil applicator is arranged to contact a strip of metal passing by the applicator and has an applicator roll in the form of a rotatably mounted hollow tubular shaft ...
