Development of a high temperature low density carbon brick and its application in furnace linings

The technical defects and causes of failure in the furnace lining structure of domestic electric reduction furnaces are analyzed. The development of a new heat insulation material, a light carbon brick, with efficiency at temperature is proposed. This is expected to improve the design concept for the domestically made long-lasting electric reduction furnace linings. In the meantime, it can fulfill the objectives of quality and energy saving under load, temperature and ratios of ores to coke, which is termed triple high conditions in the metallurgy industry.
