the embodiment comprises the following steps:

A furnace body 1 and a workpiece placement bracket 2 fixed in the inner cavity of the furnace body 1; the workpiece placement bracket 2 comprises a longitudinal metal plate 21 which is longitudinally arranged and fixed on the side wall of the inner cavity of the furnace body 1, and a transverse metal plate 211 which is transversely arranged and fixed on the side wall of the inner cavity of the furnace body 1; and the longitudinal metal plate 21 and the transverse metal plate 211 divide the inner cavity space of the furnace body 1 into four spaces with equal volumes;

The spaces between the longitudinal metal plates 21 and the transverse metal plates 211 and the furnace body 1 are provided with storage baskets 22; t-shaped sliding grooves 27 are formed in the left side wall and the right side wall of the longitudinal metal plate 21, and T-shaped sliding blocks 210 which mutually fit and slide with the T-shaped sliding grooves 27 are arranged on the surface of one side, close to the longitudinal metal plate 21, of the storage basket 22.

A plurality of longitudinal rectangular through holes 212 which are longitudinally arranged are formed in the inner portion of the longitudinal metal plate 21, and a plurality of transverse rectangular through holes 26 which are transversely arranged are formed in the inner portion of the transverse metal plate 211.

According to the optimal technical scheme provided above, the working principle of the technical scheme is explained and elucidated:

After the furnace door is closed to heat the furnace chamber of the furnace body 1, heat flow of the furnace chamber flows along the hollowed holes among the storage basket 22, the longitudinal metal plates 21 and the transverse metal plates 211, inert protective gas injected into the furnace chamber flows along the hollowed holes, the storage basket 22 is heated to conduct heat with a workpiece to transfer heat, and meanwhile, the inert gas flows to contact with the workpiece to transfer heat after being heated; and in the cooling process after the heating is finished, the low-temperature inert gas filled into the hearth flows to take away the heat of the workpiece. Therefore, the utilization rate of the internal space of the hearth is improved on the premise of not influencing the normal annealing treatment of the annealing furnace and protecting inert gas.
