Abstract
A pouring device for metallurgic vessels, particularly for steel melts, with slide plates which can be adjusted and slid out again one behind the other in a row under a vessel opening and into which filters can be inserted, and with an immersion pipe projecting into a mold. The slide plates have a filter part which is provided with openings arranged in the casting direction and at least one solid web plate part actuators are provided by which the slide plates can be displaced in the conveying direction (x-direction) and, in addition, in the same plane, but vertical to the conveying direction (i.e., in the y-direction).
Claims7
A pouring device for a metallurgic vessel, comprising:
- slide plates which can be adjusted and slid out again one behind the other in a row under a vessel opening;
- an immersion pipe beneath the slide plates, the slide plates having a filter part which is provided with openings arranged in a casting direction and at least one solid web plate part;
- first actuator means for displacing the slide plates in a conveying direction (x-direction);
- second actuator means for displacing the slide plates perpendicular to the conveying direction (y-direction) and in a common plane;
- measuring means for detecting flow through the immersion casting pipe;
- and a regulating device that places the actuating means and the measuring means in operative communication.
A method for controlling the discharge quantity of a melt which flows out of a metallurgic vessel via an immersion pipe which can be closed off by slide plates, comprising the steps of:
- guiding the melt flowing through the immersion casting pipe through a filter;
- simultaneously detecting the quantity of melt flowing through the immersion casting pipe;
- and
- adjusting a clear cross section of the filter by displacing the slide plates in a conveying direction (x-direction) and in a direction perpendicular thereto (y-direction) so that the quantity of melt flowing through remains constant.
