Description
Technical Field
The invention relates to the field of steel processing oil, in particular to stainless steel processing oil and a preparation method thereof.
Background
The steel material is an important foundation of national economy and always occupies an important position in the whole large family of materials. With the continuous development of national economy and the update of science and technology, the trend development of stainless steel in the future mainly focuses on strengthening the advantages of stainless steel, so that the stainless steel has special performance and can be used under special conditions, and meanwhile, how to reduce the research and development production cost of the stainless steel is also a direction in the future.
Among these, stainless steel has been known for over a hundred years. Stainless steel can be classified into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel, and the like according to the product structure; the steel may be classified into chromium stainless steel, nickel stainless steel, etc. according to the chemical composition of the steel. The stainless steel rust prevention mechanism is mainly based on addition of a large amount of chromium elements: on one hand, the electrode potential of the iron-chromium alloy steel is increased due to chromium, and particularly when the chromium content reaches 1/8, 2/8 and 3/8 … … atomic ratio, the electrode potential of the iron-chromium alloy steel is increased in a jumping way; on the other hand, under the corrosion medium, the chromium element can generate a layer of firm and compact oxide film on the surface of the stainless steel, thereby inhibiting further corrosion.
Compared with high-quality carbon structural steel, the stainless steel material is added with alloy elements such as Cr, Ni, N, Nb, Mo and the like. The addition of these alloy elements not only improves the corrosion resistance of the steel, but also has a certain influence on the mechanical properties of the stainless steel. For example, compared with the medium carbon steel No. 45, the martensitic stainless steel 4Cr13 has the same carbon content, but the relative machinability is only 58 percent of that of the medium carbon steel No. 45; the austenitic stainless steel 1Cr18Ni9Ti is only 40%, while the austenitic-ferritic duplex stainless steel has high toughness and poorer machinability.
In actual machining, the phenomenon of cutting and sticking of stainless steel is often accompanied. The stainless steel has large plastic deformation during cutting, the generated cutting is not easy to break and easy to bond, so that the processing and hardening are serious in the cutting process, a hardened layer is generated in the next cutting during each cutting, the hardness of the stainless steel is increased in the cutting process through layer-by-layer accumulation, and the required cutting force is increased. The generation of the work hardened layer, the increase of the cutting force inevitably leads to the increase of the friction between the tool and the workpiece, and the cutting temperature is increased accordingly. Moreover, stainless steel has a small heat conductivity coefficient and poor heat dissipation conditions, and a large amount of cutting heat is concentrated between the cutter and the workpiece, so that the processed surface is deteriorated, and the quality of the processed surface is seriously affected. In addition, the cutter abrasion is aggravated by the increase of the cutting temperature, the front cutter face of the cutter generates a crater, and a cutting edge generates a notch, so that the surface quality of a workpiece is influenced, the working efficiency is reduced, and the production cost is increased.
Therefore, when a metal technician cuts, compared with common carbon steel, stainless steel has much larger ductility under the same hardness condition, namely, the stainless steel is sticky, and simultaneously, the stainless steel has higher density than the carbon steel, the power consumption required by cutting is large, the generated heat is large, the forming temperature is high, and the cutter is easy to burn.
Because stainless steel has poor cutting processability and has higher requirements on cooling, lubricating, permeating and cleaning performances of cutting fluid, the common cutting fluid comprises the following types: mineral oils such as emulsion, vulcanized oil, machine oil, and spindle oil. The conventional cutting fluids at present are a single processing technology meeting the requirements of stainless steel, such as (1) emulsion: the common cooling mode has better cooling, cleaning and lubricating performances, and is commonly used for stainless steel rough turning. (2) Vulcanized oil: the high-melting-point sulfide can be formed on the surface of metal in the cutting process, is not easy to damage at high temperature, has good lubricating effect and certain cooling effect, and is generally used for drilling, reaming and tapping. (3) Mineral oils such as machine oil and spindle oil: the lubricating property is better, but the cooling and the permeability are poorer, and the method is suitable for excircle finish turning. Aiming at the conditions of poor machinability of stainless steel, easy cutter breakage and cutter sticking in processing and the like, the prior art mainly adopts increasing the amount of an extreme pressure agent and using imported synthetic ester, thereby greatly improving the cost and the price of oil products.

PB value: that is, when the extreme pressure performance of the lubricant is measured by the four-ball method, the maximum load at which seizure does not occur under predetermined conditions is expressed in newtons (or kg), and may be referred to as the maximum oil film strength. A larger PB value indicates better extreme pressure properties of the oil.
The diameter of the abrasion marks: under certain temperature, rotating speed, load and running time, the smaller the abrasion mark is, the better the abrasion resistance and lubricity of the oil product is.
The larger the PB value of the oil, the smaller the wear scar diameter, the better the protection for the tool, and the corresponding tool life may be extended.
From the above comparison, it can be seen that examples 1 to 6 are improved in both PB value and wear scar diameter as compared with comparative example (prior art), so that examples 1 to 6 provide not only excellent extreme pressure lubrication in cutting but also a prolonged tool life.
Meanwhile, by comparison of the costs, it can be seen that examples 1 to 6 are reduced in cost as compared with the comparative example (prior art).
