DEVICE FOR THERMAL PROCESSING OF HEXAGONAL REMOTE LATTICES

摘要

The utility model relates to nuclear energy and may find application in enterprises manufacturing fuel assemblies (FAs) of nuclear reactors in the manufacture of spacer grids. The technical task of the utility model is to increase the heat treatment efficiency of the spacer grids by reducing the heating and cooling times due to a reduction in the metal consumption of the equipment, eliminating the deformation of the spacing grids during heating and soaking in the high temperature region under the influence of gravity, and also fixing the products on the device. This technical problem is solved by the fact that the device is equipped with removable knitting needles located on each of the shelves in a checkerboard pattern, and between the products there are removable spacer elements made of a metal strip with a width equal to the double width of the protrusion of the rim of the spacer grid and having the shape of a triangle inscribed in the hexagon formed by the protrusions of the rim, the dimensions of which allow it to be installed on the field of cells and to exclude the rotation of the separation element relative to the spacer grid.
