Development and Application of High Quality Magnesite-Chrome Bricks for VOD Refining Furnaces

摘要

The paper describes the process of producing high quality magnesite-chrome bricks for VOD refining furnace. The service life reaches 14 heats, average life 12 heats. The studies show that the wear of the magnesite-chrome bricks is mainly due to chemical corrosion, thermal spalling induced by thermal shock and the corrosion aroused from accumulation of molten materials in transition zone.
