Production and Application of High Capacity Bottom Blowing Purging Plugs for Converter
The article main discusses the development, production and application of directional multi -microtubule purging plugs which used in large or medium sized bottom blowing converter. This type of purging plug makes the gas flow in the metal pipes with very small resisting force and good air tightness. It is produced by using cold isostatic pressing, and has high strength and good corrosion resistance. Mainly employed high purity fused magnesia, flake graphite as raw material, and used phenolic resin as binder, and added titanium carbide, boron carbide as antioxidants and additives, which improved anti-oxidation, corrosion resistance and washing resistance, and the life of purging plug is highly improved accordingly.
