Stabilization apparatus for moderating vibrations and oscillations of a metal strip in motion

A stabilization apparatus for stabilizing a metal strip rising from a molten metal bath along a theoretical feeding plane, the apparatus comprising

• at least one pair of air knives, a first air knife of which is arranged at a first side and a second air knife is arranged at a second side, opposite to the first side, with respect to said theoretical feeding plane;
• at least one pair of electromagnetic stabilizer devices, a first electromagnetic stabilizer device of which is arranged at said first side and a second electromagnetic stabilizer device is arranged at said second side;
• a pair of first support beams, each first support beam supporting a respective air knife;
• a pair of second support beams, each second support beam supporting a respective electromagnetic stabilizer device;
• wherein the pair of second support beams is separate from and not in contact with the pair of first support beams, and wherein the first support beams are distal from the theoretical feeding plane, while the second support beams are proximal to said theoretical feeding plane so that said second support beams are arranged, with reference to the theoretical feeding plane, in an, at least partially, innermost position with respect to the pair of first support beams;
• wherein each of the first support beams and each of the second support beams have a respective first end resting on a first side structure, and each of the first support beams and each of the second support beams have a respective second end resting on a second side structure;
• wherein the first support beams have a respective central stretch supporting the respective air knife, said central stretch of the first support beams being outermost of the corresponding first ends and second ends of the first support beams, with reference to the theoretical feeding plane, and being lowered with respect to said corresponding first ends and second ends;
• wherein the second support beams have a respective central stretch of the second support beams which is outermost of the corresponding first ends and second ends of the second support beams, with reference to the theoretical feeding plane, and which, from a proximal side of the central stretch of each of the second support beams with respect to said theoretical feeding plane, delimits a recess of the corresponding second support beam which accommodates the respective electromagnetic stabilizer device;
• and wherein the central stretches of the first support beams are arranged at a distance from the theoretical feeding plane so as to allow an accommodation of the electromagnetic stabilizer devices in a zone between said two central stretches of the first support beams.
