包内压入法是向钢包内压入稀土硅铁合金的方法。该项新工艺的研究从一九七九年开始到一九八一年获得成功,同年八月经冶金部科技办组织鉴定,认为该项工艺属国内先进水平,应推广应用,并获冶金部一九八一年重大科技成果三等奖。 该项新工艺的装置、试验结果曾在本刊一九八二年第一期作了详细报导。对30T平炉和150T氧化转炉(200吨钢包)生产09Mn和16Mn钢种试验得出的主要技术指标在表中列出。
The bag is pressed into the ladle method is pressed into the rare earth ferrosilicon alloy method. The research on the new technology was successful from 1979 to 1981, and in August the same year, it was appraised by the Science and Technology Office of the Ministry of Metallurgical Industry that the technology is of advanced domestic level and should be popularized and applied. The third prize of major scientific and technological achievements in 1981. The device of this new technology, the test result has been reported in detail in the first issue of 1982. The main technical specifications of the 09Mn and 16Mn steel grades produced from 30T open hearth and 150T oxidized converter (200t ladle) are listed in the table.
