Description

The additive that is used for cold-rolling lubricant
The cross reference of related application
The U.S. Provisional Application No.60/451 that the application submitted to based on March 3rd, 2003,473, and the right of priority of this provisional application is enjoyed in requirement.
Technical field
The present invention relates to be used for the lubricant additive that in metal processing, uses, more particularly, be used for cold rolling oil additives.
Background technology
Metal sheet adopts hot rolling or cold rolling manufacturing usually.Cold rolling process specifically is, metal sheet or metal strip raw material are sent between two rolls, pushes being lower than under the temperature of metal softening point then, causes strain hardening.The dependent variable that produces in this process has determined hardness and other mechanical property of metal finished product.The cold rolling mechanical property that has changed metal sheet or band, and reach hardness, intensity, ductility, rigidity, certain combination of other so-called tempered performance.Cold rolling major advantage is relative even metal thickness and good smooth finish.
Metal carries out making the friction between the roll that with lubricator reduces metal and milling train when cold rolling.These lubricants can also promote in metallic surface generation surface of good smooth finish.During the operation milling train, usually lubricant is sprayed to or allows it flow on the metal, from each group roller front and/or to roller originally on one's body.Introduce lubricant and can allow to adopt higher roll speed and attenuate (variation of plate thickness) degree in cold-rolled process, the roller wearing and tearing reduce, and reach consistent rolling performance.In order to be called the contact between roll gap between lubricated roller and the metal sheet, lubricant forms protective membrane on metal sheet and/or roller, can reduce friction.As a result, when making with lubricator, reduce the roller wearing and tearing, and can make slick rolled metal.
Usually, in cold-rolled process, use various lubricants always.Decide the concrete lubricating oil of use by rolling operating method and rolled metal type.Generally, will consider two importances to cold-rolling lubricant: (1) lubricant should form competent film in roll gap; (2) lubricant inherent performance should make lubricant can reduce friction and the roller wearing and tearing.Lubricant is wanted and can be worked, and the lubricant that uses in milling train must form the homogeneous layer that reduces friction materials at roller and metallic surface.In addition, along with the appearance of high speed mill, lubricant must be under the high process velocity of this milling train and load effectively.
The lubricant that uses in cold rolling also can be used as refrigerant, remove rolling during the heat that produces of roll and metal.The operation of rolling causes that metal temperature rises, and must come cool metal and roller with certain type of refrigerant.Usually, lubricant has been brought into play the dual function of lubricant and refrigerant, and therefore, the cooling performance of lubricant is usually also very important.In addition, lubricant can mix also very important with water, because water is a kind of effective, and refrigerant cheap and easy to get.
Cold-rolling lubricant often contains various additives, so that improve the lubricity of basic lubricant.These additives generally are the compounds as Fatty Alcohol(C12-C14 and C12-C18) and fatty ester.The effect of these additives is the lubricities that improve basic lubricant, thereby reduces roller and intermetallic friction.The metal thickness that friction reduces to make per pass pass through milling train can be bigger and attenuate more effectively.Additive generally also be used for reducing rolling during the roller surface possibility of picking up metallic particles.
Since at industrial practice and economically, rolling lubricant in cold rolling back and moving metal also be retained on the metallic surface usually during to the processing of back as annealing or thermal treatment.Although can remove lubricant in cold rolling back fully with special cleaning or defatting step, these steps cause too high manufacturing cost.As a result, lubricant generally also contains additive, and the pollution of metallic surface when being used for reducing annealing or between the shelf lives is if especially only use the basic lubricant with this generation pollutant performance.These additives be used for preventing metal process in the back during variable color, improve the gloss and the value of final metal product.A key property of these additives is its boiling points, because find, the lower boiling additive is general unlikely to be maintained film and can cause pollution in the metallic surface.
At last, if remaining lubricant film is stayed on the metallic surface, generalized case is exactly that so then lubricant should be atoxic to rolling workman during use, and also should be atoxic to the later user of this metal, if especially this metal is used for foodstuffs industry.
The present invention develops with regard to the cold rolling of aluminium and aluminium alloy, and is at this purposes in describing the present invention the time always.Yet, should be appreciated that to the invention is not restricted to this metal, also can be applicable to other metal process operation and lubricate be other metal of important factor.
