Definitions

  • My invention relates to rolling mills especially adapted for hot and cold rolling of metal bands and sheets.
  • the entire rolling mill can be of a lighter con- 0 the smaller diameter of the rolls
  • the bite is reduced as with the same initial thickness of the material and with the same reduction in thickness under otherwise equal conditions (composition of the material being rolled, temperature at which rolling is effected, roughness of the outer surface of the rollers, etc.,) rolls with a larger diameter grip the material better (smaller angle of bite) than rolls of smaller diameter (larger angle of bite).
  • This disadvantage is all the more of small practical importance for the application of rolls of small diameter for rolling strips and metal sheets which initially are already of small thickness, because there are means available for increasing the friction between rolled material and rolls and thus for increasing the bite.
  • the present invention now shows the method in which the known advantage of minimum diameter of the body of the roll can be utilized in a manner which is correct from the constructional and mechanical aspect.
  • nonsymmetrical rollers known per se are used and are supported wholly or in part over the entire length of the body of the roll, but according to the invention the body has the smallest diameter, the collar serving for securing the roller against axial displacement has the largest diameter and the Wobbler has an intermediate diameter lying between these two magnitudes.
  • the body serves both as working and bearing surface, the collar prevents axial displacement of the roll in one direction and the Wobbler serves the same function as the'wobbler of rolls of usual construction.
  • FIG.'1 shows a front elevation and Fig. 2 an end elevation of the novel roll
  • Fig. 3 shows a side View of a six roll mill equipped with such rolls and I 'Fig. 4 a front view partly in section of Fig. 3.
  • the rolls consist of the body'w, the collar 1) and the Wobbler k.
  • the roll is mounted between two supporting rollers in such manner that the body w is sup- (a) Greatest possible reduction in thickness at one operation.
  • a rolling mill especially adapted for hot and cold rolling of metal bands and sheets comprising a frame, rolls extending into the frame from opposite directions, a collar on each roll, a wobbler on each roll, supporting rolls in the frame for supporting one end portion of the working part of the rolls directly and exclusive- 1y, said frame having side bearings against which the collars work, theworking parts of the rolls having the smallest and the collars the greatest diameter, the diameter of the collars being sufiiciently large to bear against their respective bearings in the frame.
  • a rolling mill especially adapted for hot and cold rolling of metal bands and sheets comprising a frame, rolls projecting into the frame in opposite directions, a collar on each roll integral therewith and a Wobbler on each roll, supporting rolls in the frame for supporting one end portion of the working part of the said oppositely extending rolls directly and exclusively, said frame having side bearings against which the respective collars work, the working part of each roll having the smallest and the collars the greatest diameter, the diameter of the collars being sufficiently large to cause, thecollars to bear against the respective bearings in the frame to take up axial thrust.
