Methods To Handle Abnormal Operations Of Glass Furnace
Date:2015-12-16 10:05 From:Zhengzhou Sunrise Refractory Author:admin
Glass production process is a complicated process, and glass furnace is a high temperature dynamic operation system, when the abnormal situation occurs in the production, exclusion method is generally used, ultimately find the crux of the problem one by one, and to solve the problem and maintain normal production. During the use of glass furnace, occasionally there will be some abnormal conditions, below are some methods to handle abnormal operations.
1. Abnormal pressure of glass furnace
The furnace pressure of glass furnace is controlled by gate of the flue duct, and it is generally operated under the condition of micro normal pressure. If the furnace pressure rises, the furnace refractory material will damaged speedily, which thereby greatly shorten the service life of the furnace. In the case of the furnace operation indicators of the operation are not changed, if the furnace pressure anomaly, the problem of flue water, ash clogging and lattice block should be taken into account.
2. Temperature difference
As to regenerative horseshoe flame furnace, in normal operation, the operation of a change of fire is performed every half hour or so, and the air inlet and exhaust of the regenerator are changed. When changing the temperature of the furnace and the temperature of the storage chamber, there will be some fluctuation. In the normal operation of the furnace, the temperature variation of the upper part of the regenerator is approximate to the sine curve and the cosine curve, and the temperature of the melting part is approximated by the curve of the tooth. If in a change of fire cycle and another for the fire cycle, the difference between the temperature of the furnace and the heat storage chamber is different. In addition to the aforementioned cross wall cracks in the fire, the switch is to wear failure and other conditions, but also the fault of the converter base is more subtle.
3. Dirty material in Glass liquid
In recent years, with the rising cost of raw materials, many manufacturers are introducing a great deal of waste glass which is incorporated into the mix to reduce production costs. As there are a lot of tiles and other impurities in the waste glass, also it can not guarantee a thorough cleaning and inspection of the clean, which is coupled with the furnace refractory material, over time, in the melting pool a considerable amount of impurities are accumulated, especially with a large iron impurity density, and precipitation in the bottom of the furnace and multi colored components, thus forming dirty material layer in the bottom of the furnace. Under normal circumstances, the bottom layer of dirty data attached almost no flow at the bottom of the pool, which will not bring a significant impact on the products. But if there is a major change of the low and high temperature, it will cause the abnormal flow of molten glass in the furnace. The bottom of the pool "dirty" will be with the exception of the glass fluid flow and a unit of a stock with the glass liquid flow out into the material way, so that the glass products have obvious "dirty" defect.
Zhengzhou Sunrise Refractory Co., Ltd. is mainly engaged in the research and development of glass refractory products. Sunrise as a glass refractory manufacturer can provide professional before-after guidance and excellent products such as fused cast AZS block, fused cast alumina block, silica brick, magnesia brick, zircon brick, zircon mullite brick, mullite series brick, sillimanite brick, etc. contact us, we will do our best for you.
