Claims (5)

248 290 P R B D M fi τ. THE INVENTION CLAIMS 1. A method for producing seamless rings with increased hot-pressure elastic molding, followed by heat treatment using heat-pressurized heat, characterized in that the blank of the circular shape having an opening in the center and made of steel containing 0.40. up to 0.70% carbon, at most 1.20% chromium, at most 2.0% silicon and at most 1.10% manganese are produced by rough forging at temperatures in excess of 1000 ° C and after austenization at a temperature of 1050 to 1 200 ° C is subjected to pressure at a deformation temperature not exceeding 850 ° C for rings which are quenched within 5 to 20 seconds by rapid cooling from a temperature not exceeding 850 ° C and then released at a temperature of 400 to 480 ° C with a duration of 8 to 50 minutes, then the rings are calibrated at a temperature of at least 400 ° C with a degree of deformation not exceeding 5 ° C 2. Method according to claim 1, characterized in that the hot-formed rings after quenching and tempering are calibrated at a normal room temperature with a degree of deformation of less than 5%. 5. Method according to claim 1, characterized in that the hot-formed rings are calibrated within 5 to 20 seconds by quenching in the temperature range of 700 to 800 [deg.] C. and tempering at temperatures of 400 to 480 [deg.] C. with a duration of 6 to 50. minutes. 4. The method of items 1, 2 and 5, characterized in that the ring-shaped blanks with an opening in the center are formed by ring bands of volumetric compression 3 with a final deformation temperature not exceeding 85 ° C. 248 290 5. The method of items 1, 2 and 5, wherein the decanting is carried out in oil, water or aqueous solutions.
