The sphericizing furnace turns a plate-shaped Carbide into a spherical Carbide. The quality of heating will affect the physical characteristics of the product and the downstream processing properties.
The furnace temperature control technology of hot-rolled steel mills is used to replace the commonly used furnace temperature control method of opening/closing the fire of spheroidizing furnaces. Make the heating temperature closer to the process curve, reduce the number of valve body opening and closing times, and extend the life of the valve body
Turn on the burner when the temperature is increased, and turn off the burner when the temperature is reduced.
Disadvantage 1: Unable to accurately control the rate of cooling and close to the process curve
Disadvantage 2: The valve body is easy to open and switch frequently when holding the temperature, reducing the valve body's service life and energy consumption
