报道了钢包喂铝法及合理加铝量的试验研究结果,利用喂线装置将φ9.5 mm 铝线加入到钢包钢液深部,终脱氧喂铝量由标准1.0 kg/t 减少到合理加铝量0.3～0.5 kg/t,残铝量为0.02%～0.05%,铝的收得率由10%提高到70%,取得了良好的节铝效果与经济效益。
The results of the experimental research on the aluminum feeding and the reasonable aluminum content of the ladle are reported. The φ9.5 mm aluminum wire is added into the deep part of the ladle by the feeding device, and the amount of final deoxidized aluminum feeding is reduced from the standard 1.0 kg / t to the reasonable plus The amount of aluminum is 0.3-0.5 kg / t, the residual aluminum content is 0.02% -0.05%, the recovery rate of aluminum is increased from 10% to 70%, and a good aluminum saving effect and economic benefit have been achieved.
