<p>PURPOSE: To achieve higher efficiency of working by a method wherein a corresponding pattern is indicated and selected from a display device in which a pattern data all over the entire surface of molten metal is stored and slag-off and agitating operations are performed to allow automatic operation only confined to a location where slag exists. CONSTITUTION: When a slag-off mode is selected, slag-off pattern numbers are displayed on a plasma display 66 attached to an operation panel and a standby is placed for an input from a touch panel 69. So, an operator judges a pattern for the intended slag-off and selects and inputs a relevant pattern number. Then, a CPU searches the given pattern number among operation data previously registered in a memory 53 and transfers the data to a servo system to execute the pulling in or out of a slag with a slag-off apparatus. In the agitating operation, a scraper works being immersed almost half into molten metal but with a control method which adopts the same structure and action as the slag-off work.</p> |
