Development and Application of Low Cost Covering Powder for Ladle
Experiments of covering powder for ladle were developed to confirm chemical composition and index range with some industrial solid wastes such as coal gangue,recycled refractories,carbide slag and carbide residue of electric aluminium.Using the spray drying process and on the basis of previous tests,low priced covering powder was produced and carried out application.The experimental results show that the developed covering agent product has good spreading performance,obvious insulation effect,environmentally friendly and pollution-free use process,low cost,and achieved the expected goals.
