Description
Technical Field
The invention relates to the field of lubricants, is applied to the process lubrication process of strip steel rolling production of an acid-cold rolling combination unit, and particularly relates to high-speed wide-width cold-rolled strip steel emulsified rolling oil and a preparation method thereof.
Background
In recent years, with the increasing demand for high-speed, wide-width and high-surface-quality strip steel products at home and abroad and the development of technologies such as energy conservation, consumption reduction, clean production and the like, the application of a process lubrication technology in the field of steel rolling production is greatly promoted. High-quality strip steel such as cold-rolled automobile plates, home appliance steel and the like is in great demand. In terms of rolling production technology, the shape of a rolled piece is rapidly changed due to the action of high speed and high pressure of a roller in the rolling process, so that the rolled piece extends in the length direction and expands transversely, the surface of the rolled piece and the surface of the roller slide relatively to generate high friction and high temperature, more than 90% of deformation energy is converted into heat energy, the roller is easy to wear, the rolling operation condition is influenced, the energy consumption of a rolling mill is increased, and the surface defects of local thermal scratches, darkening and the like are easily generated on the surface of a plate strip, so that the surface quality and the size precision of the plate strip are also influenced. Therefore, the novel emulsified rolling oil adopted in the production process of the high-speed cold-rolled wide band steel not only can play a good process lubricating role, but also can effectively reduce the rolling pressure, cool the roller and the band steel and further better control the shape of the band steel.
In recent years, a great deal of work is done on the research and application of rolling oil in China, and certain achievements are achieved. The surface quality of the cold-rolled strip steel product not only directly affects the appearance of the strip steel product, but also is of great importance to the quality of downstream end products. Particularly, in the process of cold rolling of wide and high-strength strip steel, the normal operation of cold rolling production is directly influenced by the quality of a cold rolling lubrication state, and problems such as rolling mill vibration, thermal scratch, complex wave shape and the like in the production are directly related to the cold rolling lubrication state. The adoption of process lubrication in cold rolling is not only necessary, but also a key measure for improving the product productivity and the surface quality and reducing the energy consumption.
Disclosure of Invention
The invention aims to provide the emulsified rolling oil for the high-speed wide cold-rolled strip steel and the preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
the emulsified rolling oil for the high-speed wide cold-rolled strip steel is prepared from the following raw materials in parts by weight: 35-45 parts of pentaerythritol oleate, 10-15 parts of compound antiwear hydraulic oil, 4.0-10 parts of coconut oil, 2.0-5.0 parts of hydrofined mineral oil, 5.0-10 parts of trimethylolpropane oleate, 1.0-5.0 parts of fatty alcohol polyoxyethylene ether phosphate, 5.0-10 parts of vulcanized lard, 1.0-5.0 parts of zinc dialkyl dithiophosphate, 2.0-5.0 parts of compound antioxidant, 1.0-5.0 parts of petroleum sodium sulfonate T702, 2.0-6.0 parts of alkenyl succinate and 2.0-9.0 parts of nonionic compound emulsifier.
The compound antiwear hydraulic oil is compounded by three types of antiwear hydraulic oil, namely N32, N46 and N68, wherein the compounding ratio of the three types of antiwear hydraulic oil is N32 to N46 to N68= 1-3.
The compound antioxidant is compounded by two types of antioxidants of Basff L135 and Basff L57, wherein the compounding ratio of the two types of antioxidants is that the ratio of the Pasff L135 to the Pasff L57 is = 3-6.
The nonionic compound emulsifier is compounded by two types of nonionic emulsifiers of TX-7 and TX-4, wherein the compounding ratio of the two types of nonionic emulsifiers is TX-7.
The invention relates to high-speed wide-width cold-rolled strip steel emulsified rolling oil which is prepared by compounding pentaerythritol oleate, compound anti-wear hydraulic oil, coconut oil and hydrofined mineral oil as base oil, trimethylolpropane oleate as an oiliness agent, fatty alcohol polyoxyethylene ether phosphate, sulfurized lard and zinc dialkyl dithiophosphate as extreme pressure anti-wear agents in rolling oil, compound antioxidants as a bactericide and an antioxidant, T702 (sodium petroleum sulfonate) and T747 (alkenyl succinate) as antirust agents, and TX-7 and TX-4 as compound emulsifiers.
A preparation method of high-speed wide-width cold-rolled strip steel emulsified rolling oil comprises the following steps:
1) Adding pentaerythritol oleate, compound wear-resistant hydraulic oil, coconut oil and hydrorefined mineral oil into a reaction kettle, stirring, heating to 60-70 ℃, and preserving heat for 15-30 minutes;
2) Adding trimethylolpropane oleate serving as an oiliness agent into the base oil prepared in the step 1), and sequentially adding fatty alcohol-polyoxyethylene ether phosphate, sulfurized lard and zinc dialkyl dithiophosphate while stirring; adding a compound antioxidant, sodium petroleum sulfonate T702 and alkenyl succinate, heating to 75-85 ℃, and keeping the temperature for 15-30 minutes;
3) Finally, adding the non-ionic compound emulsifier into the reaction kettle, then stopping heating and continuously stirring to room temperature, and finally obtaining the brown yellow lubricating oil, namely the high-speed wide cold-rolled strip steel emulsified rolling oil.
In the step 1), the stirring speed of the reaction kettle is 450-500 r/min.
In the step 2), the stirring speed of the reaction kettle is 550-650 r/min.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides high-speed wide cold-rolled strip steel emulsified rolling oil and a preparation method thereof, the whole development trend of the existing cold rolling process is developing towards high refinement, wide and high speed, but with the development of modern high-strength steel grades, the requirements on wide strip steel, rolling speed, rolling mill efficiency and strip steel surface quality are improved, so that the service performance of the existing emulsified rolling oil is relatively insufficient. With the stricter environmental regulations and the increasing enhancement of environmental awareness, the requirements on the service performance of the rolling oil and the environmental protection are increased. The water-separating spreadability is an important index of the cold-rolled strip steel emulsion, the water-separating spreadability of the emulsion on the surface of metal is a premise that the emulsion plays a lubricating role, and the water-separating spreadability also has an important influence on the lubricating performance. After the emulsion ejected from the nozzle at a high speed impacts the surfaces of the steel plate and the roller, oil-water separation occurs, oil drops are attached to the contact surface, and the oil drops are brought into a rolling deformation front zone to generate an oil wedge effect, so that the fluid pressure between the roller and a rolled piece is increased by the oil wedge effect, the external load is balanced, and the total rolling pressure and the frictional wear are reduced.
In addition, researches indicate that the mass fraction of the emulsifier is a main factor influencing the surface tension of the emulsion, and the surface tension of the emulsion is reduced to different degrees along with the increase of the mass fraction of the emulsifier, so that the wetting property of the emulsion is improved. Because the hydrophilic group in the emulsifier is dissolved in water, the oleophilic group is combined with the emulsified oil, part or all of the water interface is covered by the oleophilic group, and the water-air interface is changed into an oil-water interface, the surface tension of the emulsion is less than that of pure water. According to Gibbs adsorption theorem, the larger the surplus generated on the surface of the emulsion by the emulsifier molecules is, the more favorable the surface tension of the emulsion is to be reduced, and the wetting property of the emulsion is further improved. According to the emulsified rolling oil, other surfactants are added simultaneously by optimizing the proportion of the emulsifier, so that the surface tension of the emulsion is effectively reduced, the wetting capacity of the emulsion on the surface of strip steel is favorably improved, the process lubrication requirements of a modern continuous rolling unit on high speed, wide width and high load can be completely met, and the emulsified rolling oil has the advantages of low cost, high lubrication performance, environmental protection and the like.
