Control method and device of RH refining furnace vacuum chamber heating system and storage medium

The invention provides a control method and device for a heating system of a vacuum chamber of an RH refining furnace and a storage medium, and the method comprises the following steps: when the temperature of the vacuum chamber is above a temperature threshold value, receiving selection of a heating mode and setting of a first heating parameter threshold value and a second heating parameter threshold value, starting an ignition program, and opening a nitrogen and cooling water stop valve; and the top lance is controlled to descend to the ignition position, the purging stop valve is closed, the oxygen stop valve, the oxygen flow adjusting valve, the gas stop valve and the gas flow adjusting valve are opened, and the burner is ignited. A first heating parameter value is collected, and when the first heating parameter value reaches a threshold value, flameout is conducted; the top lance is controlled to rise to the waiting position, a second heating parameter value is collected, and when the second heating para
