This utility model discloses a
heating furnace device with a heat treatment
atmosphere control structure, belonging to the technical field of heating furnaces. It includes a
combustion structure comprising a
fuel tank and a burner. A furnace body structure is installed on top of the
fuel tank, including a furnace wall and a cover plate. An
atmosphere control inlet structure is connected to the outer wall of the
fuel tank, comprising an inlet
pipe and a conversion box. One end of the inlet
pipe is connected to a
diffusion structure. A heating structure is installed inside the fuel tank, including an
airflow equalization plate, a heater, and vortex guide ribs. A detection component is installed on one side of the furnace wall, comprising a slide rail, a slider, and a
gas concentration detector. By setting a
diffusion structure on the outside of the furnace wall, the gas is transported and diffused in a laminar flow from bottom to top, enhancing the uniformity of gas flow and improving the
heating effect.
