Abstract:

Used magnesia carbon bricks are produced into regenerated materials.The samples of regenerated magnesia carbon bricks contains 20% regenerated materials.The structure analysis and component analysis are studied by polarizing microscope of Axioskop40,scanning electron microscopes of XL30TMP and energy dispersive X-ray of PHOENIX.The result shows that in high temperature,magnesia particles of the regenerated materials in magnesia carbon bricks are gradually eroded from the edge,fake particles are detected in regenerated magnesia carbon bricks,and anti-oxidants in used magnesia carbon bricks are whole oxidized or partial oxidized.
