Abstract

The hot stamping forming process of high-strength steel mainly focuses on the key processes of billet heating, forming, quenching and cooling, and heating the billet to austenitizing temperature is the key technology of the hot stamping forming process. In view of the high requirements for workpiece support in the multi-layer box furnace (9–11 layers), in order to ensure its reliability, we cooperate with relevant units to develop heat-resistant ceramic support tubes. In the case of satisfying the structural stability and service life, the hollow tube structure is compared with the solid core ceramic structure, the heating furnace heats up faster, and the overall structure weight is reduced. Through a large number of tests, it not only ensures the reliability of its life, but also the cost is much lower than that of traditional heat-resistant steel. At the same time, the weight of each furnace bottom is reduced. During the service life, the deformation tendency of the furnace bottom is effectively reduced, and it can be used for high-strength steel. Forming of steel, high-strength aluminum alloy sheets - production or trial of reinforced parts.
