Argon gas uses the principle of continuous casting and argon blowing
1. In the state where the liquid level in the crystallizer is not overturned, it is better that the argon blown by the stopper rod is preferably larger than the argon blown by the upper nozzle, and the argon blowing amount of the stopper rod should be as large as possible;
2. When the stopper rod rises or the liquid level fluctuates, check whether the SEN is blocked by the nozzle. If the SEN is not obstructed, it is necessary to focus on adjusting the flow at the large nozzle. The significance is greater than the stopper rod blowing argon.
3. Always pay attention to the crystallizer liquid level detection data, to achieve liquid level fluctuations of ± 3 mm is the ultimate purpose of continuous casting argon blowing, according to the liquid level detection data to be adjusted at any time blowing argon flow. The argon adjustment is summarized as a word of mouth.
4. With the change of the pulling speed, the argon blowing amount is always adjusted and changed. In general, the blowing rate of the argon blowing is also large, and the blowing rate of the argon is also reduced.
