APPARATUS AND METHOD FOR BLOWING OXYGEN IN ELECTRIC FURNACE

摘要

PURPOSE: An oxygen injection apparatus and method of an electric furnace are provided to safely control a robot by accurately detecting a collision between an oxygen injection rod and an unmelted material of a furnace. CONSTITUTION: An oxygen injection apparatus of an electric furnace comprises a slave robot(200) and a master device(300). The slave robot transfers an oxygen injection rod(210) into molten metal of an electric furnace(100). The master device comprises a controller(310), a display unit(320), and a haptic joystick(330). When the slave robot is operated, the controller calculates a collision between the oxygen injection rod and an unmelted material of the molten metal. The display unit provides an operator with visual information on a virtual space for an actual oxygen injection process. The haptic joystick remote-controls the slave robot and transmits tactile information to the operator using a vibrator according to signals of the controller when the oxygen injection rod collides against an unmelted material of the molten metal.
