The invention belongs to the field of forging, and particularly relates to a heating and conveying device for soft core forging and an application method of the heating and conveying device to solve the problem that according to existing current ultra-high temperature soft core forging researches, the sample temperature is high in the conveying process, the external environment and human factors are complex, and therefore the solid-liquid phase fraction of a material at the beginning of forging can not be accurately controlled. The heating and conveying device comprises a gas protection heating furnace and a thermal insulation transfer furnace. The gas protection heating furnace and the thermal insulation transfer furnace are matched with each other and are independent partially. The gas protection heating furnace is fixedly mounted and is used for heating a blank material for soft core forging. The thermal insulation transfer furnace is freely movable and is used for conveying the blank material to a forging workshop at a constant temperature for soft core forging. The heating and conveying device can be adopted to soft core forging experiments to accurately control the solid-liquid phase fraction of the material before soft core forging. The influence on material micro-structure and mechanical property after soft core forging by solid-liquid phase fraction and the forging technology can be researched systematically.
Description
technical field [0001] The invention belongs to the field of forging, specifically a heating and conveying device for soft core forging and its use method, which can be applied to soft core forging experiments to realize precise control of the liquid phase fraction of materials before soft core forging, and can systematically study liquid The influence of phase fraction and forging process on the microstructure and mechanical properties of the soft core after forging. Background technique [0002] Large forgings are generally forged from large steel ingots. Inside the steel ingot, due to the solidification and shrinkage of the metal, a large number of micro-shrinkage cavities and loose defects are inevitably generated. These hole-type defects are dispersed in the center of the steel ingot, destroying the continuity of the material and affecting the mechanical properties of the forging. At the same time, due to the solute redistribution during the solidification process, the...
