[0002] Core tempering heats the quenched alloy workpiece to an appropriate temperature, keeps it warm for a certain period of time, and then cools it slowly or quickly. It is generally used to reduce or eliminate the internal stress in the quenched steel, or reduce its hardness and strength to improve its ductility or toughness. The workpiece should be tempered in time after quenching. Only by combining quenching and tempering can the required mechanical properties be obtained. During tempering, a tempering furnace is used for heating, and a large amount of smoke and dust is generated in the furnace body.

[0003] There is a large amount of heat inside the smoke, and directly emitting the smoke and pollution also wastes heat.

When high-temperature smoke enters the equipment, the temperature will be high and dust will enter the equipment. Long-term operation will cause a large amount of dust to accumulate inside the equipment, affecting the internal heat exchange of the equipment.
