Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 , figure 2 Shown: the present invention relates to a kind of method for measuring the depth of hardened layer of roll body, comprising the following steps:
[0021] 1) Selection of test rolls used for testing
[0022] Choose ordinary 20# steel rolls for temperature measurement test. According to the data obtained in low carbon steel, the data corresponding to the commonly used materials of rolls can be obtained; among them: the diameter of the temperature measuring roll body is 1000mm, the length of the roll body is 1500mm, and the size of the temperature measuring hole The diameter is 8mm, and the roll neck radius is 240mm, so that more temperature measurement data in the radial direction of the roll body can be obtained.
[0023] 2) Processing of temperature measuring hole
[0024] (1) Arrangement of the base point...
