FIELD: instrument engineering.
SUBSTANCE: group of inventions relates to methods for dismantling and installing a ring band, which can find application in the operation of a roller press. Method of dismantling is that the annular band with the expansion is heated and removed from the roll core, wherein the annular band is subjected to induction heating by means of at least one induction coil. Ring bandage is thick-walled with a wall thickness of more than 100 mm and an outer diameter of more than 1000 mm. Mounting method consists in that first the ring band with the expansion is heated and shifted to the roll core, and then it is pressed into the roll core by hot pressing during cooling. Annular band is subjected to induction heating by means of at least one induction coil. Ring bandage is also thick-walled with a wall thickness of more than 100 mm and an outer diameter of more than 1000 mm.
EFFECT: ways of dismantling and installation provide a purposeful heating of the ring band.
