Description

technical field [0001] The invention relates to a high-temperature friction and wear tester, in particular to a heating furnace assembly of a high-temperature friction and wear tester and a method for using the same. Background technique [0002] The high-temperature friction and wear tester is an instrument and equipment used for material surface performance testing. It is widely used in the field of material science and technology. Chinese patent 201310311447.6 discloses a high-temperature friction and wear tester. The tester also includes a The bushing, the bushing includes a body and a limit plate located at the upper end of the body, the lower end surface of the limit plate is fixedly connected with the upper surface of the table, when the cylinder shrinks, the limit plate Can be attached to the bottom of the high-temperature furnace, the limiting plate is provided with a cooling chamber 1 filled with cooling liquid, and the body is provided with a cooling chamber 2 fil...

AI Technical Summary

Problems solved by technology

[0004] First, although cooling chamber 1 and cooling chamber 2 filled with coolant are installed to cool the shaft, this cooling method is only effective for a short period of time. If the experiment takes a long time, the coolant will inevitably be The temperature of the process continues to rise, and there is no other effective heat dissipation method to solve this problem at this time, which will lead to the failure or deterioration of the coolant, which will further cause the shaft and the limit plate to be deformed and bent by heat, thereby reducing the service life of the equipment. Therefore, the There are major technical defects in the improvement of this method

[0005] The second is that if you want to improve the life of the equipment according to the above problems, when you need to use the equipment, the single test time should not be too long, and if you need to conduct the next test, you can only wait for the equipment to cool down to a suitable temperature. low work efficiency

[0006] Third, in the high-temperature friction and wear experiment, the test piece should be completely exposed to the heating chamber of the heating furnace, so as to ensure that the test piece can be fully and accurately heated. The tray is set outside the heating furnace, which cannot guarantee whether the heating of the test piece is comprehensive and accurate. At the same time, no other detection means are set to determine the actual temperature of the test piece, so the influence of temperature on the surface properties of the material cannot be accurately projected, and the final result is Experimental data is also inaccurate

[0007] The fourth is that there is no heat insulation and heat preservation device. On the one hand, the heating furnace is completely exposed to the outside, so that heat can be continuously lost from around the heating furnace, which affects the heating performance; They are all in a high temperature state, which seriously affects the safe use of the equipment, reduces the service life of the equipment, and is easy to cause personal injury
