Radiation heating and baking process for coating film and oven equipment

The invention relates to a radiation heating and baking process for a coating film and baking oven equipment, and the radiation heating and baking process comprises the following steps: a radiation heating assembly in a heating cavity of a baking main oven heats the coating film to a first temperature, and a fan in a baking auxiliary oven continuously works to ventilate the heating cavity, so that the temperature of the coating film is increased to a second temperature; the temperature of the gas ventilated into the heating cavity is a second temperature, and the second temperature is lower than the first temperature; and gas exhausted from the heating cavity enters a gas-gas heat exchanger in the baking auxiliary box and exchanges heat with gas going to enter the heating cavity in the gas-gas heat exchanger. The baking oven equipment comprises a baking main oven used for baking the coating film and a baking auxiliary oven used for conducting air intake and exhaust on the baking main oven. The coating film is
