Abstract

PURPOSE:To permit quick attaching and detaching of a slag detector and to detect the timing for slag outflow with good accuracy by attaching the slag detector to the top end of a sliding rod and providing devices for swiveling, elevating and forward and backward moving the sliding rod. CONSTITUTION:A body 11 is faced upward by an elevating cylinder 12 and the top end of a sliding rod 20 is elevated in the stage of mounting a slag detector 21 to a long nozzle 23. The detector 21 is then moved forward by a forward and backward moving cylinder 13 and the body 11 is moved downward by the cylinder 12 to put the detector 21 into the opening of a tundish cover C. The detector 21 is thereafter swiveled at a horizontal level by the swiveling cylinder and is pressed and positioned to the side face of the nozzle 23 by a mounting frame 22. The detector 21 is then moved forward by a secondary forward and backward moving cylinder 17 to press the frame 22 to the front side face of the nozzle 23, by which the positioning of the detector 21 is completed.

In this case, since slag is floating on the top surface of the steel,
At the end of the injection of molten steel, slag Jf will flow out. For this reason, a slag detector is used at the end of this injection.
A slag detector detects slag outflow, which is essential for improving casting quality.

Therefore, just before the amount of molten steel in the ladle decreases and the slag starts flowing out, a slag detector is attached to the long nozzle to detect the slag flowing out, and after closing the sliding gate of the ladle, the slag detector is installed. The slag detector is quickly evacuated to prevent burnout (2), and air cooling is also used to prevent the slag detector from burning out.

4', when both shillings 13.17 are activated separately,
The sliding rod 20 can be moved back and forth in two steps. In order to configure the forward IV advance into a two-stage operation as described above, first, the slag detector 21 at the tip of the sliding rod 20 is activated by operating the primary forward advance cylinder 13 and the first advance cylinder 12. The purpose is to insert the slag detection pre-pickup (7) into the frontage of the MC of Tandyshiko, and then press (position) the frame 22 with the long nozzle 23 by operating the secondary forward/backward cylinder 17 as described later. .
