1969年日本某公司制定了一种向钢水中加合金的新方法,并成功地应用于用铝脱氧的连续铸钢中(异形铸钢件钢的熔炼也可采用)。此法是将直径5~20毫米的合金棒料不断地加入钢水包中,加入速度每小时50米。棒料的加入速度及其直径的选择取决于所需之含铝量和
A Japanese company in 1969 developed a new method of adding alloying to molten steel and successfully applied it to continuous casting of steel deoxidized with aluminum. This method is the diameter of 5 to 20 mm alloy bar continuously added to the ladle, the rate of 50 meters per hour. The choice of the speed and diameter of the bar is dependent on the amount of aluminum required and
