Embodiment Construction

[0046] The present invention will be described below in conjunction with specific embodiments.

[0047] A manufacturing process of a neutron-absorbing laminate with a large-radius end face angle of 45 degrees, including the following process steps, specifically:

[0048] a. Select an aluminum plate 1 with a thickness of 1mm and send the aluminum plate 1 to the shearing machine for cutting and cutting. The aluminum plate 1 cut by the shearing machine is rectangular;

[0049] b. Grinding the filler contact surface of the cut aluminum plate 1 with a grinding wheel grinder so that the filler contact surface of the aluminum plate 1 becomes rough, and the roughness of the filler contact surface after grinding is 12.5 μmRa;

[0050] c. Send the polished aluminum plate 1 into the CNC bending machine for bending treatment, such as Figure 4 with Figure 5 As shown, the aluminum plate 1 after being bent by a CNC bending machine includes an arc-shaped base 11 bent in a circular arc, an...

Abstract

The invention discloses a process for manufacturing a large-radius neutron absorbing laminate with an end face angle of 45 degrees. The method includes the following steps: a, clipping an aluminum plate; b, polishing a filling contact surface of the aluminum plate; c, performing bending process on the aluminum plate; d, manufacturing an absorbing layer pressing die; e, arranging the absorbing layer pressing die on a 80T four-column hydraulic press; f, using ethyl alcohol to clean the absorbing layer pressing die; g, evenly pasting a Teflon protective film on an arc forming surface of a forming upper die; h, performing Vaseline coating; i, putting the aluminum plate in a lower die forming groove, coating the aluminum with glue; j, putting boron carbide filling in the lower die forming groove, and then performing pre-pressing through a stainless steel roller; k, closing the dies, and keeping a pressure; l, performing static curing; and m, removing the die, and completing manufacturing of the neutron absorbing laminate. Through the steps the process can effectively produce arc neutron absorbing laminates, can be effectively used for production and processing of large-radius neutron absorbing devices.

Description

technical field [0001] The invention relates to the technical field of neutron absorbing devices, in particular to a manufacturing process of a neutron absorbing laminate with a large-radius end face angle of 45 degrees. Background technique [0002] In nuclear devices, in order to prevent nuclear radiation, neutron materials and technologies are often used for shielding protection; currently commonly used neutron absorbing materials are lead-boron polyethylene and boron-containing polypropylene, which have the advantages of simple shielding structure and low weight Light and small in size; however, lead-boron polyethylene is easy to age and has a short life, which limits its application; cadmium plates can also be used as neutron absorbing materials, but cadmium is toxic and carcinogenic; boron steel can also be used as neutron absorbing materials, However, the boron content of boron steel is too low to meet the shielding requirements. [0003] Further explanation is requi...
