提高平板玻璃引上率的途径

The Ways to Raise Drawing Rate of Flat Glass

作者讨论了垂直引上法生产平板玻璃提高引上率的途径.提出了在强化原料、燃料、熔化、成形"四大稳"和温度、液面、窑压泡界线"四小稳"的前提下,有效地控制"引上速度、熔化率和熔窑最高温度的稳定;适当提高Al_2O_3含量,并加入微量P_2O_5;制订合理的温度曲线,建立合理的玻璃液作业流梯度,最大限度地稳定工艺和热工制度;严格引上操作制度,减少原板炸裂等措施.

The article denls here with the ways to raise drawing rate of flat glass by fourcault process. Under condition to intensify the four maior stablities of raw material, fuel, melting, working and the four minor stablities of temperature, glass level, furnace pressure, foam line, the author presents a plurality of measures such as efficient centroling drawing speed, stablizing the melting rate and the maximum temperature of furnace, appropriate increasing the content of Al_2O_3 while putting a trace of P_2O_5, working out reasonable curve of temperature, establishing a proper gradient of working current of glass melt, tablizing technology and thermal system to maximum limit, rigorously enforce drawing operation, reducing the cracking of glass sheet.
