[0002] Annealing is a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at a suitable rate. The goal is to reduce hardness and improve machinability; eliminate residual stress, stabilize dimensions, and reduce deformation and cracking; refine grains, adjust the structure, and eliminate structural defects. More precisely, annealing is a heat treatment process for materials, including both metallic and non-metallic materials. The purpose of annealing new materials also varies from that of traditional metal annealing.

[0003] The existing annealing furnace needs to separate the heating zone and the equipment operation zone through the furnace core. The existing furnace core is mostly made of fireproof and heat-insulating materials, which cannot effectively adapt to the various sizes of heating equipment and molds installed in the furnace core. In addition, the disassembly, maintenance and replacement of the existing furnace core is relatively cumbersome.

[0004] In this regard, the Chinese patent application number CN201821293940.4 discloses a shell structure that is convenient for matching with the furnace core of a hood-type annealing furnace, including a mounting base, a furnace core device and a furnace cover.

[0035] In the specific setting, a sliding groove is opened on one side of the mounting seat 110, and the screw nut pair 122 is slidingly connected to the sliding groove.
