Embodiment 1
[0028] In Embodiment 1, a method of mechanical desteeling in the preparation of a dispersed fuel plate is provided, please refer to Figure 1-Figure 3 , the method includes:
[0029] Step 1: placing the hot-rolled composite plate on a hydraulic shearing machine, and using the hydraulic shearing machine to cut off both ends of the composite plate at two preset positions to expose the ends of the fuel plate;
[0030] Step 2: Use a bending machine to break the two sides of the composite board after the ends have been cut off;
[0031] Step 3: Fix the composite plate in step 2 on a vise, separate one side of the steel ladle, and use the crimping roller of the mechanical separator to separate the other side of the steel ladle to obtain a fuel plate without a sheath.
[0032] Wherein, in the embodiment of the present application, before the step 1, it also includes: analyzing the structure of the hot-rolled clad plate, there is a weak position along the length direction at the cont...

The invention discloses a mechanical steel sleeve stripping method in preparation of a dispersion fuel plate. The method comprises the following steps: firstly, placing a composite plate which is subjected to hot rolling on a hydraulic plate shearing machine, and respectively shearing the two ends of the composite plate at two preset positions by using the hydraulic plate shearing machine to expose the ends of the fuel plate; secondly, breaking the two sides of the composite plate of which the ends are shorn by using a bending machine; thirdly, fixing the composite plate of the second step on a bench clamp, separating a steel sleeve on one side, and separating the steel sleeve on the other side by using a curling roller of a mechanical separator, so that the fuel plate without a sleeve is obtained. The technical effects that the mechanical steel sleeve is stripped with high efficiency, low cost and no pollution, and no harm is brought to human bodies of working staff are achieved.
Description
technical field [0001] The invention relates to the technical field of nuclear material manufacturing technology, in particular to a method for mechanically removing steel sleeves in the preparation of dispersed fuel plates. Background technique [0002] UO 2 -Zr diffused plate type fuel element is an advanced nuclear power fuel element, and the fuel plate is its core component. Metallurgical bonding is achieved between components by high-temperature hot rolling. [0003] Zirconium materials are easily oxidized with oxygen in the air when the temperature exceeds 300°C, resulting in poor performance. In the process of fuel plate preparation, hot rolling at 800°C is required to make the zirconium cover plate and fuel core To achieve metallurgical bonding between the body and the zirconium frame, it is necessary to avoid the contact between the zirconium material and the air during the hot rolling process. Therefore, the zirconium material and the fuel core are packaged in a ...
