Heat treatment furnace for heat-resistant steel

According to the technical scheme, the heat treatment furnace is characterized in that the heat treatment furnace comprises a bottom plate, four supporting blocks are fixedly installed on the bottom face of the bottom plate, a furnace body is fixedly installed on the top face of the bottom plate, two electric sliding rails are fixedly installed on one side of the bottom plate, sliding blocks are arranged in the electric sliding rails, and the sliding blocks are fixedly installed on the bottom plate. A bracket is arranged on the top face of the sliding block, clamping blocks are fixedly installed on the two sides of the interior of the bracket, a supporting plate is movably installed on the top faces of the clamping blocks, and a fixing assembly is arranged on the top face of the bracket and used for fixing the heat-resisting steel plate. The first spring below the bracket bounces the abutting plate to drive the fixing plate to move downwards, so that the heat-resisting steel plate on the supporting plate is f
