Baking furnace for improving baking temperature and uniformity of submersed nozzle and using method

The baking oven comprises an oven body fixing base, the submersed nozzle is formed in the top of the oven body fixing base and used for wrapping an oven body, the submersed nozzle is provided with a handle and a baking nozzle, a hanging storage device is arranged at the top of the submersed nozzle, and the hanging storage device is arranged on the top of the submersed nozzle. A fixing device is further arranged at the top of the suspension storage device and is used for fixing a plate surface to protect the submersed nozzle; according to the submerged nozzle baking method, overall surrounding baking of the submerged nozzle is achieved, the submerged nozzle is more uniform in temperature and higher in baking temperature during baking, placement of the submerged nozzle before baking and taking of the submerged nozzle after baking are facilitated, and therefore the problems that due to the fact that the baking temperature of the submerged nozzle is not uniform and the baking temperature is not high, cracks, burs
