도 3은 본 발명의 바람직한 실시예에 따른 고온 마모시험장치를 도시한 정면도이고, 도 4는 그 작동시 상태를 보여주는 정면도이며, 도 5는 그 평면도이다.Figure 3 is a front view showing a high temperature wear test apparatus according to a preferred embodiment of the present invention, Figure 4 is a front view showing a state in its operation, Figure 5 is a plan view thereof.
본 발명의 고온 마모시험장치는 상대재(6)를 800℃까지의 고온으로 가열시키는 고주파가열코일(9), 상기 고주파가열코일(9)에 연결되어 주파수제어를 통해 상대재(6)를 시험온도까지 올리는 고주파발진장치(10), 상대재(6)의 표면온도를 측정하는 비접촉식온도계(11), 가열시 상대재 구동축의 변형 등을 방지하기 위해 냉각을 실시하는 냉각장치(12)를 포함한다.The high temperature wear test apparatus of the present invention is connected to the high frequency heating coil 9, which heats the counterpart 6 to a high temperature of up to 800 ° C, and the high frequency heating coil 9 to test the counterpart 6 through frequency control. It includes a high frequency oscillator 10 for raising the temperature, a non-contact thermometer 11 for measuring the surface temperature of the counterpart 6, and a cooling device 12 for cooling to prevent deformation of the counterpart drive shaft during heating. do.
고주파가열코일(9)의 가열폭은 상대재(6) 원주길이의 1/4∼1/3영역이며, 가열깊이는 상대재(6) 반지름의 1/3영역까지이다.The heating width of the high frequency heating coil 9 is 1/4 to 1/3 of the circumferential length of the counterpart 6, and the heating depth is up to 1/3 of the radius of the counterpart 6.
만약, 가열폭 및 가열깊이의 가열영역이 상기 수치보다 클 경우에는 가열속도가 증가하나 주위의 불필요한 지그 등의 장치부위가 가열되는 부작용이 발생되며, 작을 경우에는 가열속도가 느려져 바람직하지 않다.If the heating area of the heating width and the heating depth is larger than the above value, the heating speed is increased, but side effects such as the unnecessary jig around the device are heated, and when the heating area is small, the heating speed is slow, which is not preferable.
고주파가열코일(9)의 코일형상은 도 6에 도시한 바와 같이, 디긋자("ㄷ") 단면형상으로 되어 있으며, 상대재(6)와의 간격은 3㎜내로 밀착시키는 것이 바람직하다.As shown in Fig. 6, the coil shape of the high frequency heating coil 9 is in the form of a cross section (“c”), and the distance from the counterpart 6 is preferably in close contact with 3 mm.
고주파발진장치(10)는 상대재(6)가 가열된 후 시험을 위해 시험재(3)측으로 전진되면, 동시에 동일거리만큼 자동전진되어 시험중인 상대재(6)의 온도가 일정하게 유지되도록 한다.The high frequency oscillation apparatus 10 is advanced to the test material 3 side for the test after the counter material 6 is heated, and at the same time is automatically advanced by the same distance so that the temperature of the counterpart material 6 under test is kept constant. .

The angle is pre-adjusted and installed.
냉각장치(12)는 상대재(6) 가열시 고온에 의한 상대재 구동축의 변형방지 및 상대재(6) 탈부착을 용이하게 하기 위한 것으로, 상대재 구동축의 양쪽에 각각 1개씩 설치되며, 물분사식으로, 재질은 고온 및 부식에 강한 스테인레스(STS)계열이 사용되며, 주름관 파이프를 사용하는 것이 바람직하다.The cooling device 12 is for preventing deformation of the counterpart drive shaft due to the high temperature during heating of the counterpart material 6 and for easy detachment of the counterpart material 6. One cooling device 12 is provided on each side of the counterpart drive shaft, and a water spray type As a material, stainless steel (STS) series resistant to high temperature and corrosion is used, and corrugated pipe is preferably used.
여기서, 냉각장치(12)는 축의 변형방지를 위해 물을 분사하는 것으로, 분사된 물이 비산되어 상대재 온도를 저하시키지 않도록 적정 수압을 유지한다.Here, the cooling device 12 sprays water to prevent deformation of the shaft, and maintains an appropriate water pressure so that the sprayed water does not scatter and lower the counterpart temperature.
이하, 본 발명에 따른 고온 마모시험장치의 작용에 대해 설명한다.Hereinafter, the operation of the high temperature wear test apparatus according to the present invention will be described.
시험재(3)가 고온의 상대재(6)와 접촉시의 고온마모특성을 평가하기 위해 원형의 시험재(3) 및 상대재(6)를 장착 후, 작동을 시키면, 상대재(6)가 회전하면서 고주파가열코일(9)에 의해 가열되기 시작한다.In order to evaluate the high temperature abrasion characteristics when the test material 3 is in contact with the high temperature counterpart 6, the test piece 3 and the counterpart 6 are mounted, and then operated. Rotates and begins to be heated by the high frequency heating coil 9.
비접촉식온도계(11)와 고주파발진장치(10)의 제어에 의해 상대재(6) 표면이 목적하는 시험온도에 도달하면, 상대재(6)는 시험재(3)측으로 전진되며, 이때 고주파발진장치(10)도 동시에 동일한 거리만큼 고정된 본체(14)로부터 자동으로 전진되어, 상대재(6)의 온도가 저하되지 않도록 계속 가열한다.When the surface of the counterpart 6 reaches the desired test temperature by the control of the non-contact thermometer 11 and the high frequency oscillator 10, the counterpart 6 is advanced to the test part 3 side, and at this time, the high frequency oscillator 10 is also automatically advanced from the main body 14 fixed by the same distance at the same time, and it heats continuously so that the temperature of the counterpart 6 may not fall.
그리고, 상대재(6)측에 하중수단에 의해 시험하중이 가해지고, 시험재(3)도 주어진 속도로 회전되면서 마모시험이 시작되면, 냉각장치(12)가 작동되어 상대재 구동축의 냉각을 실시하게 된다.Then, when the test load is applied to the counterpart 6 by the load means, and the test piece 3 also rotates at a given speed and the abrasion test starts, the cooling device 12 is operated to cool the counterpart drive shaft. Will be implemented.
덧붙여, 본 발명에 따르면, 800℃까지의 고온으로 마모시험이 가능한 것으로 예시하였으나 본 발명은 이에 한정되지 않으며, 가열장치와 냉각장치에 의해 그 상한온도는 확장될 수 있음은 물론이다.In addition, according to the present invention, although the wear test is illustrated as being possible at a high temperature of up to 800 ℃, the present invention is not limited to this, the upper limit temperature can be extended by the heating device and the cooling device, of course.
