ル測定装置。 In a device for measuring the profile of refractories in the tank and molten steel flow pipe of a vacuum degassing device using a laser ranging device, the laser ranging device is mounted on a trolley that runs under the vacuum degassing device so that it can be raised and lowered. On this laser distance measuring device, a cooled long protective tube is rotatably installed, which is inserted from the lower end of the molten steel flow tube of the vacuum degassing device into the tube and into the tank, and the laser beam at the upper end of this protective tube is inserted into the tube and into the tank. A vacuum escaper is installed at a position sufficiently far away from the distance measuring device to irradiate the laser from the laser distance measuring device to the refractory surface to be measured and to receive the reflected laser from the refractory surface. Refractory profile measurement device in gas equipment.
