With the development of industrial technology glass,glass electric melting furnaceThe life is also extended, and the quality of the glass is significantly improved, which is related to the emergence of refractory materials and new species of refractory materials. In particular, it has a close relationship with the development of electrofused refractories in the last century. Due to its high density, wear resistance, good high temperature mechanical properties andglass electric melting furnaceThe corrosion resistance of the fused refractory material.
In the development of our country for many years, the sizeglass electric melting furnaceThe basic problem of controlling the ignition oven is that China follows the old tradition, that is.glass electric melting furnaceWarming upAfter 10-13 days, there was a fire in the temperature change range of 800-850 ℃ inside the melting furnace. However, the fire in our working temperature range mainly considered the crystal transformation of the internal structure analysis of siliceous refractories and clay refractories. According to the study of the thermal expansion coefficient and temperature distribution range of the two refractories, the fire was over. Domesticglass electric melting furnaceDuring the heating and preheating activities, it can basically heat up according to the heating curve, and adjust the stay in time and effectively, so that the refractory materials in all parts of the glass electric melting furnace are continuously expanded and uniform.
FromThe temperature fluctuation in the range of 850-1200 ℃ is large and difficult to control, sometimes fluctuating above Baidu within an hour, which will cause drastic changes in refractories, especially the crystal transformation of molten refractories at 950-1200 ℃, accompanied by 6.9% volume shrinkage.
Therefore, in this temperature range, the heating operation should take into account the electric melting.AZS materials, such as large temperature fluctuations, will cause the electric melting brick to crack.glass electric melting furnaceUnder the influence of high temperature and violent fluctuations, the corundum bricks in the kiln will form horizontal and vertical cracks in a short time, especially in the flame space, such as breast wall hook bricks, entrance arch bricks, small chimneys, small furnace openings, etc. The influence is not obvious at the initial stage of kiln operation, but in the middle of kiln operation, the hook bricks will turn over, exposing the pallet, causing the breast wall to tilt towards the kiln opening. Domestic glass enterprises have repeatedly occurred the above-mentioned serious chest wall tilt accident, resulting in collapse, water plug,glass electric melting furnacesuffered heavy economic losses.

How to ensure product stability in the selection of raw materials
1. When controlling the moisture of granularity-sensitive raw materials such as calcite white jade, in addition to conventional drying and drying treatment, microwave drying technology can be used to achieve efficient and accurate dehydration. Microwaves can penetrate the inside of the material, causing water molecules to generate high-frequency vibration friction and heat generation, which is 3-5 times more efficient and more evenly distributed than traditional hot air drying. At the same time, the near-infrared spectrometer is used to monitor the moisture content of raw materials in real time, and when the detected value deviates from the set range, the operating parameters of the drying equipment are automatically adjusted to form a closed-loop control system to ensure that the moisture content of raw materials is stable in the process requirement range.

High temperature resistance of glass electric melting furnace
The 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, what is the reason for this? I think it may be for professional glass furnace technology does not understand it. 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.
Melting process of glass electric melting furnace
The best technology for melting glass is the glass electric melting furnace. With the prospect of government support for the accelerated development of the industry, the use of glass electric melting furnace is recognized by more and more people. But there are also many people who don't know much about it, but they lack professional knowledge, so they often lead to wrong views. Today we will tell you about this glass furnace related knowledge, I hope you can read carefully.
