Abstract
The invention provides rolling oil mainly used for cold rolling of an ultrathin steel plate (the thickness is 0.16 mm-0.5 mm). The rolling oil mainly comprises synthetic ester serving as lubricant base oil, surfactant, an antioxidant, an anti-wear agent, fatty acid, an amine antirust agent, an antibiosis preservative and an oilness agent. The rolling oil is suitable for cold rolling machining of common carbon steel, a galvanized (aluminum-zinc) base plate, a tinned base plate, an automobile sheet, a household appliance sheet, LED materials and other thin steel plates, can be used for a large high-speed single-stand reversing mill and a multi-rack continuous rolling mill and can also be used for a multi-roll single-rack reversing mill.
Description
One, technical field
The present invention relates to one oil based on synthetic ester and produce cold rolling sheet rolling oil, can be used for large high-speed single chassis reversable mill, multi-frame tandem rolling mill, also can be used for the lubrication of single multi-roller stand reversible rolling mill.The invention belongs to the environment-friendly metal machine-shaping soluble oil in lubricating oil field.
Two, background technology
Cold rolled sheet (thickness is 0.165-0.5mm) has good toughness and machining property, is the staple product producing black plate, zinc-plated substrate, appliance plate, pressed sheet, therefore also referred to as very thin cold rolled sheet.In recent years, along with the development of national economy, the demand of ultrathin cold-rolled steel plate is sharply increased, during rolling, need harsh oilness and spatter property.Cold-rolled process utilizes the larger working roll of material hardness to roll metallic surface, makes it produce viscous deformation, working roll, generation friction between supporting roll and processed metal.Friction is divided into two kinds of forms: one is metal plastic deformation, the molecule internal friction between metal particle; Two be metal and working roll, external friction between working roll and supporting roll.The former causes the anneal of resistance to deformation available metal that molecule internal friction is greatly reduced, and the latter needs to use ROLLING OIL to reach the problem solving external friction in lubrication and cooling two when rolling.
The production of current Cold Rolled Sheet Steel adopts larger multi-frame tandem rolling mode more, there is the production of more thin gauge strip and the feature of high speed, high yield, at present, along with the renewal of product, cold rolled sheet is required more and more harsher, also more and more higher to the technical property requirements of rolling mill compound when this will seek common ground.The using method of ROLLING OIL is recycled by its emulsion that is mixed with soluble in water, requires that emulsion has:
(1) satisfactory stability, in use stable performance, can not to cause in the operation of rolling reasons such as rolling load is unstable, thickness fluctuation is large;
(2) lubricity is superior, guarantees oil film strength effectively, reduces the frictional coefficient between roll surface and steel plate as much as possible, also will avoid skidding between roller plate simultaneously;
(3) good antirust property, can not breaker roll, roll plate and other equipment unit causes corrosion;
(4) antifoam property is good, requires recycling non-foaming foam in process;
(5) good Antimicrobial preservative performance, can life-time service and never degenerate smelly;
(6) toxicological harmless effect, especially to no skin irritation;
(7) annealing cleanness is strong, rolls plate and do not stay spot after anneal.Product provided by the invention can meet these performance requriementss.
(8) degree of cleaning are good, ensure the spatter property of milling train and support equipment thereof in the operation of rolling, do not only have and pollute milling train and support equipment thereof, ensure the degree of cleaning of surface of steel plate.
(9) be easy to safeguard, be easy to safeguard in the use procedure of rolling mill compound, the deflection of a wider range in the compatible operation of rolling can be had when rolling technology has large change.
Lubricating status in the contact in rolling of cold-rolled process is the boundary lubrication condition between hydrodynamic lubrication and extreme boundary lubrication.When boundary lubrication, oiliness improver provides necessary oil film thickness and oil film strength, to reach the object of the frictional force reducing friction surface in cold rolling process.Therefore the selection of oiliness improver is most important for the performance impact of cold-rolled lubricating oil.Conventional oiliness improver has the lipid acid of animal-plant oil, higher fatty acid, high fatty alcohol, synthesis type cruel.Animal-plant oil has good lubricity and load bearing capacity, but antioxidant property and low temperature flowability poor, facile hydrolysis, after directly annealing without electrolytic degreasing, surface of steel plate detergency is poor.Lipid acid and aggretion type lipid acid are also widely used in metal working fluid, fatty acid compound is to reduction static friction coefficient Be very effective, have stronger adsorptive power to metallic surface, but oil soluble, anti-oxidative stability are poor, standing storage can produce precipitation and layering.Esters oil agent utilizes fatty alcohol and lipid acid under the effect of catalyzer, carry out esterification to obtain, and compared with other oiliness improver, its resistance to elevated temperatures, antioxidant property, resistant to hydrolysis performance and sticky temperature, sticky pressure performance, lubricity are all good.The preparation of this ROLLING OIL in the past adopts animal-plant oil to be main raw material more, and the feature of animal-plant oil is easy to emulsification, and lubricity is good, but easily putrid and deteriorated, and annealing cleanness is poor.In order to expand the source of raw material, mainly adopt synthetic ester now, the oilness of synthetic ester, anti-shear ability, Antimicrobial preservative performance and annealing cleanness can better, and biodegradable.More active to the research of this product both at home and abroad, because harsh to environmental requirement abroad, keep away in the use procedure of rolling mill compound and unavoidably have race to emit Seepage, so research and development biodegradation type ROLLING OIL has been the developing direction of China.
Three, summary of the invention
Object of the present invention be exactly to prepare a kind of be adapted to present situation large high-speed continuous mill or single chassis reversable mill needs and the water-soluble rolling oil of excellent performance, this ROLLING OIL has the annealing cleanness energy of excellent lubricity, milling train clean-up performance and excellence.
