In order to figure out the void evolution law and its control technology during forging, systematic study was carried out by both numerical simulation method and industrial test. Firstly, void evolution during forging along the height direction and the width direction of the ingot was simulated by deform-3D which is a widely used numerical simulation software. Subsequently, the void closure law by single direction forging and double direction forging was analysed comparatively, the results showed that the single direction forging was more beneficial to close the void. Based on the above study, the new forging technology to control void defect was proposed and industrial experiment was carried out. The results showed that the void defect in the forging produced by the new technology was lighter than that by the original.
