Abstract
Method and apparatus for determining when the cast of a blast furnace is substantially completed in a blast furnace cast system wherein direct viewing of the taphole is obstructed during the cast. In a system wherein viewing of the taphole is obstructed by hood means covering the iron trough, substantial completion of the cast may be determined by sensing changes in ambient conditions, e.g., a change in temperature within the hood means, vibration of the hood, and/or a change in the color of the flame generated at the discharge end of a slag runner.
