AI Technical Summary
Technical Problem
In existing box-type calcining furnaces, the airflow cannot fully contact the bottom of the workpiece when heat-treating mold steel workpieces, resulting in uneven heating.
Method used
The design incorporates a heat insulation component, an airflow guiding component, and a support component. The hot airflow delivered by the fan contacts the bottom surface of the workpiece on the support rod, thereby heating the bottom of the workpiece.
Benefits of technology
This technology enables uniform heating of the bottom of mold steel workpieces, solving the problem of uneven heating.

Abstract
This utility model discloses a calcining furnace for producing mold steel, including a calcining furnace body with a door, and a first heat insulation plate between opposing surfaces of the calcining furnace body; a heat insulation assembly including a guide rail installed on the inner side wall of the calcining furnace body and a second heat insulation plate connected to the guide rail; and an airflow guiding assembly including a fixed frame fixed to the second heat insulation plate by bolts, a fan fixed to the fixed frame by bolts, a guide plate, and an air conveying assembly. The air conveying assembly includes an air conveying pipe connected to the fan, an air collecting pipe connected to both ends of the air conveying pipe, and an air inlet hood penetrating the first heat insulation plate and connected to the air collecting pipe. Through the designed heat insulation assembly, airflow guiding assembly, and support assembly, the hot airflow delivered by the fan contacts the bottom surface of the workpiece placed on the support rod, achieving the effect of heating the bottom surface of the workpiece. The box-type calcining furnace has an airflow conveying mechanism that contacts the airflow with the bottom of the mold steel workpiece.
