High temperature resistance of glass electric melting furnace
Glass processing industry in our country belongs to the unpopular industry, engaged in very few people, but our country's annual demand for glass is indeed the world's first, such a large demand-supply ratio has not led to a large number of practitioners to switch, this is what reason?glass electric melting furnaceTechnology does not understand. Many people have never been involved in this field, and their technical understanding is not much, so this is the main factor in the current shortage of talents in the glass industry.
The biggest problem of electrode water jacket lies in the process of electrode propulsion. According to the design of electrode propulsion, it needs to be propelled once every 3 months at the fastest and once every 7 years at least. For example, in float kiln designed by fic, the difference of propulsion time is so large, mainly due to the glass type, melting rate, especially the propulsion design structure. The electrode water jacket is usually damaged during the pushing process. The main reason is that the cooling water needs to be closed in order to push the electrode, so that the overall temperature of the water jacket rises, causing the solidified glass near the water jacket to soften to achieve the purpose of pushing. Almost all the electrode water jackets are made of heat-resistant stainless steel and need to withstand a high temperature of 1100 ℃. However, after pushing the water jacket, the biggest problem occurs in the water jacket, because the temperature at the front of the water jacket is as high as 1100°C, the cooling water needs to be added very slowly to prevent damage caused by large temperature differences. As the kiln operator is already hot and tired during the electrode pushing process, he hopes to finish the work as soon as possible. In the actual operation process, the water inlet is often not slow enough. The waterway can be disassembled by ordinary employees. It takes less than ten minutes and only three tools are needed to completely separate and complete the whole process. Due to the large cross-sectional area, the water quality requirements for cooling water are not high. In fact, when necessary, you can also use river water directly. The removable waterway does not directly contact the water jacket itself. It has an air barrier to ensure that the cooling water only acts on the front end of the water jacket, thus reducing or completely eliminating star cracks in the refractory caused by thermal shock.
glass electric melting furnaceThere are still many aspects of the technology that we have not said. We look forward to more people who are interested in the glass processing industry can contact us, and we will give you the greatest technical support.
Because the high borosilicate glass has the characteristics of low expansion rate, high temperature resistance and high strength, the glass is roasted at 630℃. so this type of glass is widely used. What are the advantages of high borosilicate glass compared with ordinary glass? Let me introduce to you briefly!
Because the low coefficient of thermal expansion, it is not easy for high borosilicate glass to crack under harsh temperature like soda lime glass. Therefore, many industries regard this kind of glass as a good choice for producing products. What other advantages does it have? Let's introduce it to you briefly.
In order to improve the service life of the feeder belt and its frame, and at the same time improve the uniformity of feeding, the Delta version.The YS type feeder is upgraded and adjusted as follows.
Phenomenon: During on-site debugging, such situations often occur: the same voltage and current are inconsistent when measured by different instruments, with deviations as small as 20~30 and as many as 60~70. So which is more accurate in measuring electricity meter, pointer meter or multimeter?
Because of its good chemical stability, bottle glass has no pollution to the contents; because of air tightness and high temperature resistance, a certain mechanical strength and reliable use; because of transparent or colorful and help to improve the grade of goods. Therefore, bottle glass is mainly used for product packaging in food, alcohol, beverage, medicine and other industries.
The air-cooling system of the pool wall of the electric melting furnace may not be of any use in the early stage of the furnace, but it shows its function in the later stage.
