Progress of Refractory Materials for Glass Furnace
In recent years, the glass industry with high energy consumption and high pollution has been restricted by the national environmental protection policy. What is more worrying is that with the continuous expansion of glass production capacity, the relationship between the supply of glass products in the market is becoming more and more obvious. Many glass manufacturers are facing the pressure of declining market and declining profits. In order to change the current dilemma, it is necessary to do everything possible to reduce the operating cost of the glass kiln and reduce the pollution of the external environment in the glass production process. As a result, refractories for the traditional glass industry need to be able to better adapt to changes in glass furnace operating conditions. For example, in the process of changing from burning petroleum fuel to burning petroleum coke fuel, a large amount of S02, V205 and other impurities are introduced, and the erosion of refractory materials is intensified. Thus, it is necessary to take the corresponding kiln temperature increase, glass temperature rise, speed up the flow rate, strong scour the bottom of the pool, the pool wall refractory problem. For example, the glass kiln heat storage chamber is also widely used magnesium lattice brick, resulting in serious six valence Ming pollution problems. Therefore, the country may soon introduce mandatory regulations to restrict the use of magnesium refractory materials in the glass industry.
