我国电熔耐火材料的生产现状与发展方向

一、前言电熔耐火材料是砌筑玻璃熔窑的池壁、喷火口、胸墙等部位的主要耐火材料.它不仅能耐高温(1600℃以上),而且抗玻璃液的侵蚀能力强.近二十年来,我国玻璃工业由于电熔耐火材料逐步推广应用,使玻璃熔窑的作业温度提高了30～40℃,熔化率也随着提高,玻璃质量有所改善.窑炉的使用寿命由原来的一年半左右,提高到二年半左右.不仅为国家多生产了玻璃,而且减少了窑炉的热修及冷修费用.     

玻璃和耐火材料工艺发展的相互影响

用于玻璃窑炉的耐火材料分为Ａｌ２Ｏ３－ＺｒＯ２－ＳｉＯ２，Ａｌ２Ｏ３－ＳｉＯ２，ＺｒＯ２－ＳｉＯ２，ＭｇＯ－Ｃｒ２Ｏ３，Ａｌ２Ｏ３，ＺｒＯ２及ＳｉＯ２等８类，和玻璃液接触的耐火材料及仅限于Ａｌ２Ｏ３和ＡＺＳ两种。玻璃工业用由于耐火材料的改进，高温熔化操作及成型方法的发展（从垂直引起上浮法工艺）其质量与生产能力有显著的提高，玻璃窑炉的寿命已能长达１０年，未来对耐火材料的要求是熔融玻璃具有高抗侵蚀性。

Service of refractories in a glass-tank furnace producing glass fiber by the single-stage method

Conclusions Chromium oxide blocks developed by the Ukrainian Scientific-Research Institute of Refractories from fine-grained and coarse-grained compounds, like the chromium oxide refractories S-1215 material made by the Corhart company of the USA, ensure a high resistance in the linings of the tanks of glass furnaces producing glass fiber. Their wear occurs on account of chemical solution in the glass at temperatures above 1500°C.Magnesite-chromite refractories rapidly react with aluminoborosilicate glass and cannot be recommended for the second layer of the structure of the glass tanks.Mullite-corundum refractories are subjected to rapid wear in the crown of glass furnaces due to the interaction with vapors of the glass batch at high temperatures.In order to increase the length of the operation of fiber-producing furnaces we recommend that the first and second layers of the tank lining, the channel, and the feeder be made of chromium oxide refractories, and the suspension walls and roof of the furnace from corundum refractories. These recommendations are being used for building the furnace for a second campaign.Translated from Ogneupory, No. 1, pp. 5–12, January, 1980.     

EFFECT OF STEELWORK ON HEAT LOSS THROUGH GLASS TANK BOTTOMS

An approximate mathematical method is worked out for determining the effect of steel supporting members underneath a glass tank on the heat loss from the glass tank and the surface temperature of the refractories. A series of charts has also been prepared for the rapid calculation of heat loss and surface temperature, if the thickness and thermal conductivity of the refractories and the details of the steelwork are known.

Effect of the glass composition on corrosion of zirconium-containing refractories in a glass-melting furnace (a review)

Different chemical compositions of glasses and the individual characteristics of their reaction with zirconium-containing refractories are examined. When such refractories are used for lining glass-melting furnaces, it is necessary to consider the chemical compositions of the glass which will be melted in these furnaces.     

Methods of determining the corrosion resistance of glass-tank refractories

Conclusions When laboratory investigations are being carried out to find resistant refractories for glass tank furnaces it is desirable to make simultaneous use of indirect and direct methods of assessing corrosion resistance.The use of indirect methods for determining corrosion resistance in refractories permits us to explain the nature of the interaction between the refractory and glass, to study the nature and properties of the reaction products, and also to select refractories that form with the glass the most infusible or viscous reaction products for subsequent investigation in molten glass.The direct methods permit direct determination of the rate of corrosion of refractories by glass at working temperatures and allow us to recommend the most corrosion resistant refractories for tests in service conditions.In laboratory conditions we established that the most corrosion resistant refractories in regard to original glass used for obtaining slag sitalls are bakor-33 and dense zirconium refractory. This may be explained by the formation of viscous reaction products in the contact layer which have a protective action on the refractory.Translated from Ogneupory, No. 5, pp. 56–60, May, 1967.     

Service of chamotte articles in furnaces for melting aluminum

Chamotte bricks are studied after service in the tank of a furnace for melting secondary aluminum. The deterioration of the lining is caused by the reducing action of molten aluminum mainly on the silica contained in the refractory. It is inferred that high-alumina refractories are more suitable for such furnaces.     

Production and performance of dense corundum refractories

Conclusions The production technology was developed and production was launched of dense superduty corundum refractories with mullite—corundum binder. The products proved to be highly durable in the lining of a channel type induction furnace at the Volga Automobile Plant.The refractories are used also for the masonry of the roof of the high-temperature glass furnaces used in the production of glass fiber and are suitable as lining material for in-vacuo steel refining installations and other high-temperature heat-using equipment.Deceased.Translated from Ogneupory, No. 7, pp. 17–18, July, 1978.
