This utility model provides a large cast iron baking plate, including a cast iron baking plate body with symmetrically arranged heat-insulated handles on both sides. The interior of the cast iron baking plate body has a ventilation cavity, the bottom of the body has an exhaust vent, and the outer surface of the body has a smoke exhaust vent. Both the exhaust vent and the smoke exhaust vent are connected to the ventilation cavity. In use, by creating a ventilation cavity inside the cast iron baking plate body and providing an exhaust vent at the bottom and a smoke exhaust vent on the side, an airflow channel is formed. This creates a "fire-drawing tube" effect, where the air in the ventilation cavity is heated and its density decreases during fuel combustion. The high-temperature flue gas rises rapidly and is discharged through the smoke exhaust vent, continuously creating a low-pressure zone within the ventilation cavity. This causes cold air from the bottom of the furnace to be drawn into the furnace to replenish oxygen, forming a self-circulating airflow and improving the completeness of fuel combustion in the oven.
