However, in the heat preservation stage, along with the saturation of the heat absorption of the aluminum round bar, the power of the burner is greatly reduced, and the gas consumption is greatly reduced. Meanwhile, the homogenizing process requires that the temperature deviation of furnace gas and an aluminum bar in a heat preservation stage is generally less than +/-5 ℃, and even the requirements of certain special aluminum alloy processes are less than +/-3 ℃, so the low-power output of the burner is required to be stable.

The power requirement of the burner brings about a plurality of problems for controlling the burner. Particularly, in the later heat preservation stage, the power load of the burner is required to be greatly reduced, and the method is generally realized by combining two methods of pulse control and power reduction.
