Forging of Large Pieces in Final Passes,
Abstract
In planning technology for forging large pressed pieces in the final pass, the heating temperature during forging is selected as a rule on the basis of the degree of deformation (forging reduction ratio). Thus, for example, under the conditions prevailing at Uralmashzavod, the metal is heated to a maximum forging temperature of 1200 degrees centigrade in the final pass for a forging reduction ratio greater than 1.5 (1250 degrees centigrade for carbon steels), to 1100 degrees centigrade for a forging reduction ratio of 1.3 to 1.5, and to 1000 degrees centigrade for a forging reduction ratio less than 1.3. This complicates the performance of the technology to a significant degree: it reduces the efficiency of the forging assemblies, promotes the formation of surface defects due to low-temperature forging, and complicates the formation of batches in the reheating furnaces.
