1983年我厂从国外某公司引进一座铅晶质玻璃全电熔炉,每天可以熔制3.5~6.0吨中铅晶质玻璃。通过实际安装、运行操作,得到一些经验。这里着重介绍该设备在运行过程中所发现的问题和解决措施。 1.操作控制问题 电熔炉运行伊始,该公司决定让我厂采用全自动控制。由于在电熔炉中采用恒温控制工艺本身较难实行,所以滞后现象非常严重,系统中各部位的参数波动太大,输入功率在190~240kW间波动,电阻在0.190~0.209Ω之间波动,温度控测器(玻璃熔化池高温计GBP)显示在1330~1374℃之间波动。这样不仅增加能耗,还使玻璃液质量不够稳定。所 相似文献

Manufacture of glass melting pots .—The raw materials used, the methods of grinding and mixing the raw clay and grog, and the way in which pots are built and dried are briefly described for the purpose of impressing glass makers with the amount of labor and care involved. At present only one grade of pot is made; but the difficulty of getting a pot suitable for all kinds of glass suggests the desirability of making special grades of pot for use with specified kinds of glass. Proper treatment of pots by the glass maker .—The authors emphasize the importance of gently handling pots and of storing them in a warm and dry place. The precautions to be taken in preheating pots in arches are discussed at length for this is the critical period in the life of the pot. The batch should be properly crushed and mixed and should either be preheated or loaded in gradually; and the furnace temperature should be carefully regulated. It is particularly urged that the technical treatment of pots in the glass be entrusted to a man trained in ceramics and physical chemistry. Arches for heating glass melting pots .—After discussing the usual design the authors suggest improvements as to fire box locations, construction of walls and door, etc. 相似文献

The addition of small amounts of iron oxide (0.1 to 0.2%) to soda-lime-silica glass batches exerts a profound influence in increasing the output of glassmelting tanks as well as in favoring the production of higher quality glass. The color produced by this addition, moreover, is not objectionable for many uses of the ware. The accelerated melting rate probably is the result of a chemical effect of iron oxide in the batch and a physical property possessed by such glass to absorb radiation from the flames more efficiently. Attempts to measure these effects were made by rioting the melting rate of glasses which contain varying additions of iron oxide and by determining the temperature gradient that exists in glass when it is melted in a miniature tank. The presence of iron oxide aids melting and fining in crucible melts at 1200°C., but no effect was observed at higher temperatures. The measurement of temperature gradients in a pot holding 45 lb. of glass and heated by flames passing over the glass surface showed that the temperature gradient increases with iron oxide content. 相似文献

The laboratory scale experiments for determining the influence on the distribution of phosphorus by.adding Al-containing component in melting furnace were conducted. It is found that the addition of Al-containing component in melting furnace increased the amount of phosphorus in slag phase. Thermodynamic analysis of the industrial sludge melting process with the addition of different Al-containing components was also carried out. The compositions of slag and the gas in three different zones in melting furnace were obtained. The results also demonstrate that increasing the mole ratio Al/P of charged materials is an effective way to fix more phosphorus in slap, which can help reduce the amount of H3PO4 precipitate from guy in the waste heat boiler later. 相似文献
