The temperature control of float glass melting kiln is the key link of glass production,which has an important impact on the stability of glass temperature regime,the stability of glass liquid flow field and the melting quality of glass liquid.By briefly describing the cooling method of traditional external fan and combining the practical experience of float glass process in actual production,In order to realize the precise control of the furnace temperature,a strategy of temperature control of float glass furnace based on PID control is put forward.
