Abstract
A method and an installation (10) for removing slag allows both slag removal and metal recovery from slag (60′) to be performed quickly and easily. The risk of slag fires is reduced.
Claims10
A method for removing slag from a metallurgical melt (12),comprising:
- providing a slag removal unit (10) cooperating with a melting furnace (14), comprising:
- a base (28);
- a draw-off blade (40) attached to a mast (38) arranged on the base (28), and a counter-blade (48) arranged on the base (28);
- drawing off the slag (60, 60′) from the melt (12) with the draw-off blade (40);
- moving the counter-blade (48) into a position opposite the draw-off blade (40);
- pressing the slag (60, 60′) between the draw-off blade (40) and the counter-blade (48);
- and transferring the slag (60, 60′) into a slag container (62).
4 more elements
An installation (10) for removing slag from metallurgical melts (12),wherein the installation (10) is adapted to withdraw slag (60, 60′) from the melt (12) in a melting furnace (14), and wherein the installation (10) comprises:
- a base (28);
- a draw-off blade (40) arranged on a mast (38) supported on the base (28), for extracting the slag (60,60′) from the melt (12);
- and a counter-blade (48) arranged on an arm (50) supported on the base (28), the counter-blade (48) being movable into a position opposite the draw-off blade (40), wherein the slag (60,60′) is pressed out between the draw-off blade (40) and the counter-blade (48) before transferring the slag (60,60) to a slag container (62).
