Definitions

  • Purpose of the present invention is that of conceiving a new type of structure of the rolling mill plants in which higher advancing speeds can be reached, for reaching and exceeding also 150 m/sec.
  • a rolling system of the type involving at least one couple of opposite rolling cylinders or rolls, characterized in that it is made up as follows: - each rolling cylinder or roll is directly controlled at the axis of at least one respective electric motor which is in electric axis with the respective motor which controls the opposite rolling cylinder or roll; - means for controlling, changing and/or co-ordinating the speeds of all the electric motors operating said rolling cylinders are provided so that each couple has the same rotation speed.
  • Advantages of the invention The electric axis thus allows to eliminate the constraints of the mechanical drive with all the subsequent advantages.
  • Advantageous is the use of electronic control and programming systems managed by a computer in order to control and program the speed of the respective couples of cylinders or rolls in order to overcome the problem of whether or not changing the angular speed of one couple of rolls or cylinders respect to the other, because it is obvious that the best performance is obtained when the different cylinders or rolls are endowed with the peripheral exact rolling speed according to the rolled section advancing speed in that precise rolling point. For such reason for example the couples of cylinders or rolls would need different angular speeds.
  • a typical case is the stretching of the rolled section during the rolling process, and it is known that the stretching involves a higher advancing speed, so that the downstream cylinders or rolls should rotate at an angular speed higher than the upstream ones, obviously proportioned to the reduction of the rolled section (thus an higher stretching of the rolled section). 1
  • the advantage is not only that of simplifying but also of reaching

  • Figure 1 is a view of a rolling stand according to this invention.
  • FIG. 2 shows the arrangement of the couple of embossed rolling rolls ( 1 , 2) with a single system for adjusting their position (4), single supporting block (3), articulated shafts ( 1 1 , 12) and respective motors in electric axis Ml , M2, in this case with extended winding along the axis for the diametrical dimension reduction.
  • Fig. 3 shows another solution as a variation of the previous one in which there are two offset motors Ml, M2.
  • Figure 4 is a solution with adjacent embossed rolling rolls 1 , 2 and stand block (G) only on one side, in which after the respective supports (3) there are two motors for each roll axis (Ml-Ml ; M2-M2) offset and spaced by articulated axes 11 , 12.
  • Figure 5 is a front view of two opposite embossed rolling rolls and each supported by a rolling unit (G) where an adjusting system (4) is provided for the rolling roll 1 , 2 position being the rolling rolls 1 , 2 supported by embossing 3 and in which each roll 1 , 2 is operated by articulated axis (1 1-12) to a respective single electric motor (Ml , M l ).
  • Figure 6 shows a further solution as variation to the previous ones in which the motors Ml and M2 are opened wide by tilting during the opening wide of the respective connection axes 11 , 12.
  • Fig. 7 shows a side view of a rolling block involving on a support (S) a plurality of rolling stands (G) with embossed rolls (1 , 2) of the type according to previous figures, placed tilted at 45° and in which each couple of rolling rolls is orthogonal to the other.
  • Figure 8 is a front view of the rolling block according to previous fi gure . In the specific case of these latter two figures, there are five rolling blocks on one side and five rolling blocks on the other for a total of 20 rolling rolls, each operated by respective electric motor in electric axis.

Abstract

Ce dispositif de laminage, du type comportant au moins un couple de cylindres de laminage en opposition ou rouleaux (1, 2), se caractérise par le fait que chaque cylindre de laminage ou rouleau (1, 2) est directement commandé sur l'axe d'au moins un moteur respectif (M1, M2 ...) et qu'il comporte des moyens permettant de réguler la vitesse de tous les moteurs (M1, M2 ...) entraînant lesdits cylindres de laminage, de modifier cette vitesse et/ou de la coordonner, ce qui permet à chaque couple de tourner à la même vitesse de rotation.
