[China Glass Net] 1. Melting temperature curve: The setting of the melting temperature curve is determined according to the structure of the kiln. You can't see what other production lines use. You should consider the refractory capacity when setting the curve. It is possible to ensure that the carcass has no high temperature points and neither high heat load parts.

The characteristics of the double high curve: (1) The longitudinal temperature difference of the melting zone of the kiln is small, and the carcass is evenly heated. (2) The melting speed is fast, and the melting rate of the kiln of the same scale is high. (3) The clarification temperature is high and the microscopic quality defects are small.
The requirements for the use of double high curve: (1) The line of the No. 1 small furnace should not be too close to the front face, otherwise it will be damaged due to the excessive temperature of the front face wall. (2) Not suitable for small furnaces. (3) It is better to use single gun oil quantity control.
2. Melting flame control: Flame is the source of melting temperature. The control of burning flame is good or bad, which directly affects the burning speed of kiln burning, such as: longitudinal temperature of flame, rigidity of flame, height of flame angle, length of flame, etc. Wait.
3, the fluctuation of the liquid level control, the fluctuation of the liquid level directly affects the erosion speed of the pool wall, the greater the fluctuation, the faster the erosion speed.
4. The fluctuation control of the kiln pressure, the kiln pressure is generally controlled at the micro-positive pressure of the glass surface. The higher the pressure, the faster the erosion speed of the upper space of the kiln body, the negative pressure can not be controlled by the kiln pressure, otherwise the cold air will cause fire resistance. The material bursts.
5. The melting detection means is complete and timely: the complete means means that the small changes in the melting process of the kiln can be detected and can be adjusted in time, so that the kiln is in a stable state, and an abnormality can be dealt with in time to prevent deterioration.
