The monitoring of electrical characteristics of furnace operation provides valuable information about the wear pattern of the lining. This should be checked daily when the furnace is full or nearly fu

At weekends or whenever the furnace has been cooled to low temperature, it is a good practice to measure average lining diameter as well as depth and compare with original dimensions. The diameter has

Any small localized broken or worn out portion on the furnace lining can be easily patched up using air-setting refractory. The area should be thoroughly cleaned by removing slag and the refractory sh

During day to day furnace operation, the lining is subjected to various kinds of thermal stresses, mechanical loading, and metal-lining reactions. As a result, some minor or major type of lining wear

Temperature control: For safe furnace operation and long lining life, it is essential that the maximum temperature is not unduly exceeded beyond the safe temperature. In fact by paying more attention

Magnesia (Mg0) is a basic lining. It is made from either naturally occurring carbonate ore or is synthetically produced from seawater, It is graded in size from 0 to 5 mm, but somewhat coarser to sili

Alumina (Al203) is neutral in nature. Among the three lining materials, it has the highest negative free energy of formation. Hence it is the most stable oxide. Alumina refractories are produced form

In nature, there is no such refractory which meets all these properties. From among the available refractories, three types meet the important properties for specific applications. These refractories
