南京钢铁集团第三炼钢厂年产钢量在100万吨左右,集束氧枪为电炉冶炼主要辅助手段,现使用精制焦炉煤气(热值4200kcal/m~3)作为主氧燃烧助燃集束保护气。共有3支,分布于电炉4、8、9#水冷板位置。精制焦炉煤气管道压力为0.6-0.8MPa,进站压力大于0.6tMPa,集束氧枪最大氧气耗量为10200m~3/h,最大煤气流量为2160m~3/h(720m~3/h×3支)。
The third steelmaking plant of Nanjing Iron and Steel Group, with an annual output of about 1 million tons of steel, beam oxygen lance for the main auxiliary smelting furnace, is the use of refined coke oven gas (calorific value 4200kcal / m ~ 3) as the main combustion combustion combustion cluster protection gas. A total of 3, located in the electric furnace 4,8,9 # water-cooled plate position. Refined coke oven gas pipeline pressure 0.6-0.8MPa, pit pressure greater than 0.6 tMPa, the maximum oxygen consumption of cluster lances 10200m ~ 3 / h, the maximum gas flow of 2160m ~ 3 / h (720m ~ 3 / h 3).
