Description
Technical Field
The invention relates to an isothermal graded quenching oil composition for a bearing, a preparation method and application thereof.
Background
Quenching is a heat treatment process in which the steel is heated to a temperature above the Ac3 or Ac1 point for a certain time and then cooled at a suitable rate to obtain martensite and/or bainite structures. Quenching is an important link in mechanical manufacturing and processing, and aims to improve hardness, strength and wear resistance so as to improve the service performance of parts. The quenching oil is used as a quenching medium, has the largest consumption at present, plays an important role in the heat treatment process of the bearing, and is also widely applied to industries such as automobiles, tools and dies, fasteners, wind power, household appliances and the like.
The main material of the bearing is high-carbon steel GCr15, and in addition, carburized bearing steel, stainless bearing steel, high-temperature-resistant bearing steel and medium-carbon impact-resistant bearing steel are also adopted. The bearing material is generally carburized and quenched, so that a hardened layer is formed on the surface of the steel to a proper depth, the hardened layer has proper hardening depth and a fine structure, and the bearing has high requirements on the deformation control of parts, high requirements on the cooling performance of quenching oil, and high-temperature cooling speed and low-temperature cooling speed. The traditional bearing heat treatment process mainly comprises 40-60 ℃ cold oil quenching and isothermal graded quenching above 120 ℃. The former can generally obtain better through-hardening effect and deep hardening layer, but has the defects that the deformation is difficult to control and even the hardening crack is difficult to control; the latter generally meets the requirements of the deformation, but at the same time the hardenability and hardness are reduced. For the reasons, the current bearing quenching trend is to carry out isothermal stage quenching at a lower temperature by adopting an oil temperature of 90-100 ℃, so that the advantages of the two traditional bearing heat treatment methods can be obtained simultaneously. The novel bearing heat treatment process needs to be matched with special isothermal graded quenching oil for the bearing with the use temperature of 90-100 ℃.
The Chinese patent application CN1078489A discloses an isothermal grading quenching oil composition, the main components of which comprise mineral base oil, a cooling catalyst, an antirust agent, a brightener and an antioxidant; the Chinese patent application CN103710083A discloses an isothermal graded quenching oil composition, which further improves the cooling performance, thermal oxidation stability and brightness of isothermal graded quenching oil and has certain short-term rust resistance. However, the isothermal graded quenching oil in the existing literature is more suitable for the traditional isothermal graded quenching at the temperature of more than 120 ℃, and is not special quenching oil for the bearing heat treatment process, so that a good effect is difficult to obtain in the novel special quenching process for the bearing.

[ example 9 ]
Example 9 the isothermal graded quenching oil compositions for bearings of examples 1 to 8 were applied to the isothermal graded quenching process of bearings at a relatively low use temperature, and the isothermal graded quenching oil compositions for bearings of examples 1 to 8 and the oils of comparative examples 1 to 5 were tested, specifically, the following tests were performed:
data for measuring the cooling performance, viscosity, and flash point of the isothermally graded quenching oil compositions for bearings in examples 1 to 8 by using the IVF queue cooling performance tester by the test method of ISO 9950 are listed in table 3, and data for measuring the cooling performance, viscosity, and flash point of the isothermally graded quenching oil compositions for bearings in comparative examples 1 to 5 are listed in table 4.
TABLE 3 Performance data of isothermal graded quenching oil compositions for bearings of examples 1 to 8
Table 4 comparative examples 1 to 5 various performance data of the isothermal graded quenching oil composition
Comparing the data in tables 3 and 4, it can be seen that the maximum cooling rate in the cooling performance of comparative examples 1 to 5 is also reduced when the isothermal graded quenching oil composition is applied at a lower temperature, i.e., 90 to 100 ℃, as compared to comparative examples 1 to 5, so that the maximum cooling rate is hardly higher than 92.5 ℃/s when the composition of comparative examples 1 to 5 is applied at a lower temperature, whereas the maximum cooling rate is not lower than 96 ℃/s as seen in examples 1 to 8. In addition, the cooling speed at 300 ℃ of the examples 1-8 is lower than that of the comparative example, which shows that the method is more favorable for reducing the deformation of parts and eliminating the cracking phenomenon. The results show that in the embodiments 1-8, when the bearing workpiece is subjected to heat treatment at a lower temperature, the bearing workpiece can reach the depth of a hardening layer and the hardness, and meanwhile, the deformation and the cracking of parts are effectively prevented.
