<p>The device (48) comprises a first metal cylindrical brush (58) to remove the surface layer of intermetallic compound during an operation of brushing the surface of a crucible, a vacuum arranged near the first brush to aspirate the dust produced by brushing operation, means for automatically applying a cleaning product on the surface of the crucible before the passage of the first brush, a transverse sponge arranged longitudinally ahead of the first brush and intended to be impregnated with the cleaning product, and a second brush (60). The device (48) comprises a first metal cylindrical brush (58) to remove the surface layer of intermetallic compound during an operation of brushing the surface of a crucible, a vacuum arranged near the first brush to aspirate the dust produced by brushing operation, means for automatically applying a cleaning product on the surface of the crucible before the passage of the first brush, a transverse sponge arranged longitudinally ahead of the first brush and intended to be impregnated with the cleaning product, and a second brush (60) with metal cylinder at the back that is rotating parallel to the first brush ahead by a motor (64). The crucible comprises a horizontal concave upper surface, which is intended to contain a molten feeding metal capable of forming a surface layer intermetallic compound on the surface of the crucible. The first brush is rotating around a transverse axis (A) in a frame, by the motor to automate the brushing operation. The frame comprises an upper cover. The frame is carried by a movable carriage along a longitudinal direction to allow the passage of back to front of the first brush above the concave surface of the crucible. The second brush turns in a direction opposite to the direction of rotation of the first brush. The first and second brushes are rotated by the common motor. The first brush has a width for cleaning all crucibles in one stroke.</p> |
