This lubricating oil for the cold rolling oil for the steel sheet contains (a) oils which contain 12-14C fatty acids in an amount of >=50 wt% in fatty acids composing oils and (b) compound esters.
Description
Technical field
The invention relates to the cold-rolled lubricating oil and the employed lubricating oil thereof of steel plate.
Background technology
Steel plate as cold-rolling of steel plate the time the ROLLING OIL plenum system, circulating ROLLING OIL plenum system and two kinds of modes of direct type ROLLING OIL plenum system are arranged, so-called circulating ROLLING OIL plenum system is, supply with a large amount of ROLLING OIL emulsions to steel plate and roll, used ROLLING OIL emulsion is recycled, remove wearing and tearing iron powder wherein, life-time service, so-called direct type ROLLING OIL plenum system is, supply with a spot of ROLLING OIL emulsion to rolled sheet material, meanwhile supply with a large amount of water to roll, used ROLLING OIL emulsion no longer recycles and handles as waste water.
In the past, when direct type is supplied with cold rolling (hereinafter to be referred as direct cold rolling), used independent plam oil or butter or the ROLLING OIL of having added oiliness improver and extreme pressure additive, and mixed the emulsion that forms 6-20 weight % with water and use.But, because the emulsion of high density is to prepare by mechanical stirring merely, thereby the emulsion particle diameter instability, the oil content adhesion amount on roll and rolled sheet material changes, and causes problems such as oilness instability.In addition, oil-water separation is bad, and the oil recovery rate during wastewater treatment is not high.
In recent years, carry out many kinds for rationalization of production rolling, carry out high-speed rolling with speed, and produce high tension force, therefore require direct cold rolling oil to have good lubricity and lubrication stability and low cost for the wall thickness that reduces steel plate above 1800 meters/minute.
In the past be the direct cold rolling oil of main component with plam oil or butter, though cost is lower, because its fusing point height, (Japanese is: ミ ル rotation り) bulk deposition around milling train, operating environment is worsened, but also cause fire failure, thereby require ROLLING OIL to have lower fusing point.
In addition, steel sheets such as Tinplate will pass through operations such as alkali lye cleaning, continuous annealing after rolling, plating tin then, but in these operations, still can clean bad, in annealing furnace owing to problems such as the roll stores cause Surface Defects in Steel Plate, and plating is bad.It is believed that this is that the ROLLING OIL generation thermal degradation when attached on the steel plate causes the reduction of being washed property to cause because the steel billet temperature after rolling is higher.By deterioration preventing agents such as interpolation antioxidants, can suppress thermal degradation when to a certain extent, also can avoid the problems referred to above by changing wash conditions, but so productivity reduces, production cost improves.
As the countermeasure that addresses these problems, people had once proposed the scheme of various ROLLING OIL.For example, as the ROLLING OIL of using the oil soluble macromolecular compound ROLLING OIL of putting down in writing among the JP-A7-150184 is arranged, but this ROLLING OIL is subjected to the influence of the water quality of employed water, thereby the lubrication stability deficiency, the problems such as being washed property when failing to solve eutectic and revealing with high-speed rolling.In addition, ROLLING OIL as the amine salt that uses petchem and organic phosphate ester acid, the ROLLING OIL of putting down in writing among the JP-A9-53089 is arranged, though this ROLLING OIL can solve the oilness problem, but lubrication stability is undesirable, and wastewater treatment and eutectic are revealed and the problems such as being washed property during high-speed rolling are not resolved yet.
On the other hand, when adopting in the past circulating ROLLING OIL plenum system to carry out cold rolling (hereinafter to be referred as circulating supply with cold rolling), as ROLLING OIL, use with butter and plam oil as base oil and cooperate oiliness improver, extreme pressure additive, rust-preventive agent and antioxidant etc., with emulsifying agent and water make its form O/W type emulsion, the ROLLING OIL of the low concentration of 1-10 weight % usually.But, be the cold-rolled lubricating oil in the past of main component with the natural fats and oils, though cost is low,, thereby around milling train, piled up many scum silica frost because fusing point is higher, operating environment is worsened, but also cause accident such as fire.In addition, also there are problems such as long-term cyclical stability deficiency.
In addition, same with direct cold rolling oil when carrying out high-speed rolling with the speed that surpasses 1800 meters/minute, produce problems such as the not enough and washing of oilness is bad.
As the countermeasure that addresses these problems, people have proposed multiple ROLLING OIL.For example, the ROLLING OIL of using lipid and complex ester class is disclosed in JP-A10-231494.The problems such as being washed property of the occasion (when being equivalent to low speed) that oilness when though this ROLLING OIL can solve high-speed rolling and long-term cyclical stability and rolling back steel billet temperature are lower, but in the occasion of carrying out the real machine high-speed rolling, when the steel billet temperature after rolling is higher, be difficult to obtain being washed property fully.
Summary of the invention

(c) macromolecular compound of composition can use to mix more than a kind or 2 kinds and use.The surface potential of ROLLING OIL particle is born, and along with the interpolation of (c) composition, the surface potential of ROLLING OIL particle roughly becomes 0, and the ROLLING OIL particles aggregate form thick particle diameter, thereby tack is very good, demonstrates very excellent oilness.When further adding (c) composition, the surface potential of ROLLING OIL particle become on the occasion of, simultaneously because protective colloid action; the ROLLING OIL particle forms big particle diameter and emulsifying dispersivity is also fine; thereby tack is good, demonstrates good lubricity, and long-term cyclical stability is also very good.When further adding (c) composition again, though emulsifying dispersivity is fine, because the particle diameter of ROLLING OIL becomes medium particle diameter, thereby tack is very not good, demonstrates the tendency that oilness reduces.Therefore, for direct cold rolling oil, consider that from the aggegation effect angle of ROLLING OIL particle the addition in the lubricating oil family is advisable at 0.01-0.5 weight %, preferably 0.01-0.1 weight %.Addition is in this scope the time, and aggegation is respond well, can not take place automatic emulsified or emulsification disperses, and the particle diameter of ROLLING OIL is suitable.In addition, for circulating supply cold-rolled lubricating oil, consider that from ROLLING OIL particle diameter and long-term cyclical stability angle the addition in the lubricating oil family is advisable at 0.1-3 weight %, preferably 0.5-2 weight %.Addition is in this scope the time, and the ROLLING OIL particle diameter is bigger, and long-term cyclical stability is also very good.
Cold-rolled lubricating oil of the present invention with lubricator in, except mentioned component, can also add various known additives as required, for example oiliness improver, extreme pressure additive, antirust inhibitor, antioxidant and emulsifying agent etc.
As oiliness improver, for example can use the lipid acid such as polymeric acid of oleic acid, tallow fatty acid, palm oil fatty acid, ready denier oil acid, in lubricating oil family, can add 10 weight % at most.
As phosphorus is extreme pressure additive, for example can enumerate the aromatic series amine salt of trioctyl phosphate, Tritolyl Phosphate, tricresyl phosphate oleyl alcohol ester, dioctyl phosphate ester acid, dilauryl phosphate ester acid, tributyl phosphate, trioleyl phosphate, double tridecyl phosphate ester acid, acid di(2-ethylhexyl)phosphate oil base ester, single 2-ethyl hexyl phosphate ester acid etc.In addition, as sulphur is that extreme pressure additive for example can be enumerated sulfuration greases such as sulfuration lard, sulfuration butter and vulcanized vegetable oil ester, the various active forms of olefine sulfide, sulfurized mineral oil and active form not, dibenzyl disulfide, di-t-butyl two sulphur, zinc dialkyl dithiophosphate etc.These extreme pressure additive can be a kind, also can 2 kinds of mixing use.Its addition uses according to the scope of the 0.5-5.0 weight % in the lubricating oil family.Addition is many more, and the raising of oilness is big more, but when surpassing 5.0 weight %, the price of oil improves, and simultaneously, the raising of ovenable roasting property reduces with respect to the increase of addition, thereby impracticable.Improve the effect consideration from the price and the oilness of oil, the scope of 1.0-3.0 weight % is more desirable in practicality.
As antirust inhibitor, for example can use esters such as lipid acid such as alkenyl succinic acid and derivative, oleic acid, sorbitol monooleate, benzotriazole and derivative thereof and other amine etc.Their addition is the highest with respect to lubricating oil family can reach 2 weight %.
In addition, for example can use 2, aromatic amines such as phenolic compound, phenyl alpha-naphthylamine, thiodiphenylamine such as 4-ditertbutylparacresol, four [methylene radical-3-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic ester] methane etc. as antioxidant.Their addition is the highest with respect to lubricating oil family can reach 5 weight %.
In addition, for example can use nonionogenic tensides such as anion surfactants such as triethanol amine oleate, mersolates, polyoxyethylene nonylplenyl ether, polyoxyethylene sorbitol trioleate as emulsifying agent.In lubricating oil family, can add 2 weight % at most.
Cold-rolled lubricating oil lubricating oil of the present invention, from the angle consideration that alkali lye removes oiliness (or claiming alkali degreasing) and economy, its iodine number is advisable at 5-50, preferably 10-40, preferably 10-35.In addition, consider that from reducing the accumulation angle of ROLLING OIL on the milling train rotating mechanism fusing point of this lubricating oil is advisable at 10-40 ℃, preferably 15-35 ℃, preferably 20-30 ℃.
Cold-rolled lubricating oil of the present invention can adopt known method that the lubricating oil of the invention described above is scattered in the water and makes.In addition, (c) composition also can add respectively with (a) and (b) composition and other composition.The Dilution ratio of this moment has no particular limits, and as direct cold rolling oil, the concentration of lubricating oil is 1-20 weight % usually, 6-20 weight % preferably, in addition, as circulating supply cold-rolled lubricating oil, usually the concentration of lubricating oil is 1-10 weight %, makes emulsion and sprays supply roll and surface of steel plate.When concentration was low, the adhesion amount on surface of steel plate reduced, and can not obtain sufficient lubricant effect.In addition, in ROLLING OIL, also can cooperate above-mentioned various additives.
When cold-rolling of steel plate, the emulsion of plam oil and butter is supplied to the surface of roll and steel plate by sprinkling, thereby the accumulation that produces ROLLING OIL and scum silica frost around milling train.In addition, the surface of steel plate temperature raises during high-speed rolling, attached to the ROLLING OIL thermal degradation when on the steel plate, form high viscosity, thereby being washed property reduces significantly.In the present invention,, make the fusing point of ROLLING OIL reduce, alleviated the ROLLING OIL around the milling train and the accumulation of scum silica frost owing to be the complex ester class that contains (b) composition in the lipid formed of specific lipid acid at (a) composition.In addition, because the iodine number of ROLLING OIL reduces, resistance to thermal deterioration greatly improves, even thereby the surface of steel plate temperature raises when high-speed rolling, it is also little to raise attached to the rolling oil viscosity on the steel plate, suppressed the reduction of being washed property, and oilness significantly improves.In addition, by the specific water-soluble high-molecular compound of an amount of interpolation (c) composition, as direct cold rolling oil, the surface potential of ROLLING OIL particle is neutralized, owing to agglutination forms big particle, thereby the increase of the adhesion amount on surface of steel plate, oilness improved.Owing to the protective colloid action of these water-soluble high-molecular compounds forms the ROLLING OIL particle of macroparticle, can keep stable for a long time, thereby also improve lubricated stability.In addition, because these water-soluble high-molecular compounds disperse ROLLING OIL particle homogeneous, thereby also has the effect that prevents that spout etc. from being stopped up by foreign matter.And water-soluble high-molecular compound produces sequestering action to Ca ion and Fe ion, thereby the particle diameter of ROLLING OIL is not subjected to the influence of water quality by its addition decision, has satisfactory stability.In addition, as circulating supply cold-rolled lubricating oil, emulsifying dispersivity is good, improves for the weather resistance of the leakage of rolling abrasion powder and machine oil, thereby can keep the ROLLING OIL particle diameter steadily in the long term, keeps the good rolling lubrication at initial stage for a long time.
Use the cold-rolled lubricating oil of lubricating oil of the present invention, compare with ROLLING OIL in the past, oilness and being washed property are all fine, thereby the productivity can improve high-speed rolling the time.And, because fusing point is low, having reduced the accumulation around milling train of ROLLING OIL and scum silica frost, the danger of fire, product appearance is low and problems such as deterioration operating environment improve.In addition, because the being washed property during high-speed rolling do not reduce, can avoid using the increase of the production cost that cold-rolled lubricating oil in the past causes.In addition, very stable because the character of ROLLING OIL emulsion is not subjected to the influence of water quality, long-term cyclical stability is good, thereby compares with ROLLING OIL in the past, and operational stability has improved, and can produce steel plate with lower cost and high efficient.
