MOLTEN IRON SAMPLING METHOD

摘要

PURPOSE:To automatically sample molten iron in a fixed shape from a fixed depth by detecting the reach of a sampling rod to the surface of molten iron by means of an earth current, and then causing the rod to descend into molten iron at a fixed speed for a fixed period of time. CONSTITUTION:A top end arm 8 is caused to descend by a robot 7 and when the top end of a sampling rod 9 which is insulated and impressed with a voltage reaches the surface of molten iron 2, an earth current is caused to flow through and by this, the reach of the rod is detected. The rod 9 is then caused to descend into molten iron at a fixed speed for a fixed period of time and it is raised up after reaching a specified depth of molten iron 2. By this composition, molten iron of a fixed depth can be automatically sampled in a fixed shape.
