Abstract：

The production equipment and process of nuclear fuel neutron absorption plate were introduced, and the reasonable parameters of heating temperature of billet, heating temperature of extrusion container and extrusion speed were determined by combining theoretical analysis with numerical simulation. Then, the experiments were conducted by 5 and 26 MN metal extrusion presses, and the extrusion speed of nuclear fuel neutron absorption plate of 0.8-1.0 mm·s-1 and the heating temperature of extrusion container of 490-510 ℃ were determined. Furthermore, according to the extrusion speed requirement, a closed-loop precise control system of extrusion speed at low speed was developed to realize stable extrusion of nuclear fuel neutron absorption plate at low speed, and according to the extrusion temperature requirement, an accurate extrusion temperature control system with on-line die heating was developed. On this basis, a 36 MN extrusion production line for nuclear fuel neutron absorption plate was established, and the neutron absorption plates of aluminum-based boron carbide which is difficult in deformation was extruded in China for the first time. The results show that all data of plates meet the requirements of nuclear fuel storage tank.
