<p>PURPOSE:To continuously and accurately measure molten steel level in a mold in the height direction without being influenced by powder, etc,. to safely execute this measuring work and to provide the measuring instrument enabling excellent maintenance. CONSTITUTION:An optical fiber 3 is embedded in wall or closely stuck to surface of the mold 2 and pulsative laser beam projector 32 and reflecting beam intensity analyzer 7 are connected to one end of this optical fiber 3 and converted as each scattered position and temp. at this position with the scattered beam intensity and the passed time from each position of the projected laser beam with a CPU 5 and outputted to a CRT 6, etc., as almost continuing temp. information in the mold height direction and also inflection point of the temp. is decided as the molten steel level 12.</p> |
