The main principle of glass electric melting furnace
glass electric melting furnaceAlso known as electric melting furnace, also known as electric melting furnace, when people find that high temperature glass can conduct electricity, electric energy can be used as a heat source to melt glass, that is, glass electric melting furnace to melt glass. The cellar of flames began to beglass electric melting furnacebyReplace.
Glass tank furnaces with flame surface heating have a long history and culture,Although a lot of structural improvements have been made in the process of long-term development and use management.,But there are still serious shortcomings for some problems.:such as low thermal efficiency,Kiln body structure is more complex,Bulky,Poor working and living environment, etc..
In20Century40at the end of the decade,glass electric melting furnaceused in commercial production. From the use effect,glass electric melting furnaceThe advantages are high melting rate, simple structure, high degree of automation and good working environment.
glass electric melting furnaceThe main principle is to use electric energy as a heat source. Silicon carbide or molybdenum disilicide resistance heaters are usually installed on the side walls of the kiln for indirect resistance radiation heating. Induction heating is used in some special glass melting furnaces. Eddy currents are generated in the furnace and in the liquid glass.glass electric melting furnaceThe glass liquid in the furnace is directly used as a heating resistor, and a plurality of multi-layer electric comparators are arranged at different heights of the glass liquid to heat the glass liquid, and the temperature system is controlled by adjusting the power consumption. In this way, the temperature of the space above the glass level is very low(called the cooling of the furnace roof), So the energy is basically consumed in the heat dissipation of the molten glass and the furnace wall, and there is no heat loss and environmental pollution when the flue gas is discharged, and the heat utilization rate is high,glass electric melting furnaceThere is no need to provide a combustion system and a waste heat recovery system. The battery kiln can be automatically controlled, with few managers, good working conditions, but large power consumption. Suitable for melting refractory glass, volatile glass, black glass. Theglass electric melting furnaceProduction of bottles and jars of glass every day150Tons.
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.
