PRESS FORGING OF MOLTEN STEEL
Abstract
The article deals with experiments on the press forging of molten steel. The purpose of the experiments was to determine optimum pressure and the effect of optimum pressure and the configuration of the part produced on the mechanical properties, density, and macro- and microstructures of steel. The two variations of the process are: (1) the steel is poured into the die and pressed by a punch with a shape corresponding exactly to the shape of the part being produced; (2) the molten metal is compressed between the upper and lower plates during downward motion of the ram and shaped in the die itself. Specimens cut out in different directions from articles forged from molten steel showed higher strength and ductility than both cast or rolled steel. No difference was found between the mechanical properties of longitudinal and transverse specimens. A comparison of the densities of complex shapes in various thickness sections showed that deviation from maximum density was only 0.02 g/cc. An X-ray examination and hydraulic tests confirmed the high density of steel forged from molten metal. (Author)
