<p>The invention relates to a frame (30) for a device for holding and replacing plates for transferring molten metal contained in a metallurgical vessel having a casting channel (20), the frame defining a housing (32) for receiving and holding a plate (34), when the device is assembled, in the operating position in the vicinity of the casting channel (20) of the metallurgical vessel, the frame (30) being arranged to enable the introduction of the plate (34) into the housing (32) and the extraction of the plate (34) from the housing (32) by translation along a plate insertion direction, the housing (32) being formed so as to have an overall planar symmetry in relation to a plane of symmetry (50) parallel with the plate insertion direction, the frame (30) comprising, on either side of the housing (32) in relation to the plane of symmetry (50) of said housing (32), slots for receiving thrusters (54) intended, when the device is assembled, to apply a force, in the direction of the metallurgical vessel, on a plate (34) inserted in the housing (32). The slots for receiving the thrusters (54) situated on either side of the housing (32) do not match in the planar symmetry defined by the plane of symmetry (50) of the housing (32).</p> |
