[0003] The annealing furnaces in the prior art are divided into electric heating annealing furnaces and gas heating annealing furnaces. Electric heating annealing furnaces use resistance wires for heating, and their control is more convenient, but they require more electricity, consume a lot of energy, and are costly; The gas-fired annealing furnace is heated by burning liquefied petroleum gas, and its cost is low, but the temperature of the flue gas discharged is still high, and energy waste is serious
The disadvantage of the prior art is that there is still a lack of an annealing furnace heating method with low cost and high energy utilization efficiency

Description
technical field [0001] The invention relates to heat treatment technology, in particular to an annealing furnace which burns liquefied petroleum gas for heating. Background technique [0002] Annealing is one of the common heat treatment processes. It heats the metal to a preset temperature according to a certain rhythm, keeps it for a certain period of time, and then cools it at an appropriate speed. This reduces the hardness of the metal and improves the cutting performance, thereby eliminating residual stress and reducing the tendency of deformation and cracks. [0003] The annealing furnaces in the prior art are divided into electric heating annealing furnaces and gas heating annealing furnaces. Electric heating annealing furnaces use resistance wires for heating, and their control is more convenient, but they require more electricity, consume a lot of energy, and cost more; The gas-fired annealing furnace is heated by burning liquefied petroleum gas, and its cost is re...
