Antirust oil removal and processing part inspection device for new roll {ANTICORROSIVE REMOVING AND PROCESS PART INSPECTING DEVICE FOR NEW ROLL}
[20] The present invention smoothly removes the rust preventive oil necessarily applied by the roll maker to prevent corrosion when a new roll is entered into the mill stand rolling line, and detects the abnormality of various processing parts to prevent the operation of the mill stand and reduce work efficiency. The present invention relates to a rust preventive oil removal and processing unit inspection device for a new roll.
[21] In general, when a roll is newly received, the rust preventive oil applied to prevent corrosion is removed from the roll maker, and if there is no problem after inspecting the abnormality of the processing part, the roll is ground through a grinder and used in a mill stand. .
[22] As shown in FIG. 1, the rust preventive oil applied to the new roll 1 is scraped by a worker by using a brush or the like after manually applying the washing oil to the new roll 1.
[23] After the rust-preventive oil applied to the new roll 1 is removed through this process, various processing parts of the new roll 1 should be inspected, which is usually a barrel part 2 and a journal part. 3), the end (WOBBLE PART) 4, and the clamp groove portion 5 and the key groove portion (6).
[24] The diameter of each inspection unit can be inspected by the operator using a micrometer or a measuring instrument, but the roundness of the clamp groove 5 or the flatness of the key groove 6 and the flatness of the roll end 4 are generally measured. Guro is difficult to test.
[25] Recently, in order to solve this difficulty, devices have been proposed to change the direction of rolling rolls and to detect keyways and clamp grooves. However, these devices can only detect the circumferential roundness in the circumference of the clamp groove. It is difficult to judge whether the direction is round, and it is difficult to judge whether the depth of the key groove is uniformly processed even when the key groove is inspected, and it is difficult to judge whether the depth of the key groove is uniformly processed. Because of the judgment, there were inherent disadvantages that the operator had to read while moving along the flaw needle.
[26] In addition, the flatness of the roll end cannot be inspected, and thus the mill stand is stopped because the coupling of the mill stand is not assembled when the mill stand is inserted.
[27] The present invention was created to solve the conventional problems as described above, by heating the washing oil and the rust preventive oil together in the state to be soaked in the wash rolls in the wearing oil to reduce the viscosity of the rust preventive oil to facilitate the removal of rust preventive oil and At the same time, it is possible to easily inspect not only the width and depth of the keyway but also the power in the circumferential and width directions of the clamp groove and the flatness of the roll end by means of a separate improved flaw detection means. Its purpose is to provide anti-rust oil removal and processing part inspection device for new rolls to further improve productivity.
