摘要： Apparatus to replace a guide unit in a continuous casting machine. A platform is positioned, during use, at the side of a casting line, and is provided with at least a first positioning zone of at least a first guide unit and at least a second positioning zone of at least a second guide unit. The platform is associated with a rotation device to take, on each occasion, the first positioning zone or the second positioning zone facing the side of the casting line. A movement device moves the second guide unit from a positioning zone outside the platform and, during use, in line with the casting line, to the second positioning zone of the platform and to move the first guide unit from the first positioning zone of the platform to the positioning zone outside the platform and, during use, in line with the casting line.

摘要： An oscillating table comprising

an oscillating structure, inserted in a fixed frame adapted to be fixed integrally to the ground, the oscillating structure being adapted to accommodate an ingot mold provided with a crystallizer, defining a casting direction X, and adapted to be guided in an oscillation by elastic means arranged transversally to the casting direction,
at least one actuator, adapted to transmit pulses with an alternating orientation, upwards and downwards, to said oscillating structure, so as to cause an oscillation motion thereof,
wherein said elastic means comprise pairs or elastic bars having two respective ends fixed to the fixed frame, and having a respective central portion constrained to the oscillating structure,
wherein two first elastic bars are arranged parallel to each other, at a first side and at a second side of said fixed frame, respectively, said first side and said second side being parallel to each other and equally spaced apart from said casting direction X,
wherein two second elastic bars are arranged parallel to each other, at said first side and said second side respectively, below the first elastic bars,
wherein the first elastic bars are inclined by a first acute angle with respect to a horizontal plane,
and wherein the second elastic bars are inclined by a second acute angle, different from said first acute angle, with respect to said horizontal plane.
