Being the manner which measures the crosswise destal position of the cold rolling steel sheet being crosswise central position measuring method of crosswise destal position

摘要

It can provide microwave transmission antenna 3R and microwave reception antenna 4R in furnace wall 1R of the right side, the microwave which is emitted from microwave transmission antenna 3R, is reflected in the right side edge of cold rolling steel sheet, 2 is designed in such a way that the reflected wave is received with microwave reception antenna 4R. Similar, it can provide microwave transmission antenna 3L and microwave reception antenna 4L in furnace wall 1L of the left side, the microwave which is emitted from microwave transmission antenna 3L, is reflected in the left side edge of cold rolling steel sheet, 2 is designed in such a way that the reflected wave is received with microwave reception antenna 4L. After transmitting microwave, until it receives the reflected wave, when it designates time as t, designates the speed of microwave as c, distance to the object which reflects microwave is required with t c/2. It is difficult to receive the influence of noise and atmosphere, at the same time, installation being easy, it is possible to offer the cross direction end position measuring method of the belt-shaped body whose mechanical interference of the belt-shaped body is little.
