摘要
本文研究了一种Si—Al-Ba脱氧剂在实验室条件下的应用效果,试验发现:Si-Al-Ba优于铝及Si-Al-Fe脱氧剂,铝利用率高,有利于控制钢中夹杂物,钢的力学性能也有所提高,有较好的经济效益和应用前景。
The authors have studied the deoxy effections of a kind of Si--Al--Ba ferroalloy deoxidant in laboratory conditions.The results have shown that deoxidant is superior to aluminum as well as Si-Al-Fe deokidant,aluminum utilinzation ratio in the ferroalloy is higher than that of the others,the Si-Al-Ba ferroaloy is oonducive to modifying the nometallic inclusions in steels and improving the mechanical propehies of the steels in some extent,its econowical benefit and utilized vistas are better.
