The automatic wind ring structure adopts the double outlet mode, in which the air volume of the lower tuyere is kept constant, and the upwind circumference is divided into several air ducts, each of which is composed of a wind chamber, a valve and a motor, which adjusts the opening degree of the air duct by the motor-driven valve, and controls the

In the control process, the thickness of the thin-film signal is transmitted to the computer. The computer compares the thickness signal with the current set average thickness, according to the thickness deviation and curve change trend of operation, control motor drive valve movement, when thin film, the motor forward movement, the tuyere off small; instead, the motor moves in reverse, By changing the air volume of each point on the circumference of the wind ring and adjusting the cooling rate of each point, the transverse thickness deviation of the film is controlled in the target range.
