国外从事废钢铁的研究大体上是从本世纪初开始的。早在1900年,美国钢铁协会和巴特勒研究所就分别对美国的金属拥有量作过估计。1926年,美国出版的《锈蚀及其成因与根源》一书的作者对美国1924年的金属积累量估计为4.57亿吨。同年,原苏联的矿石金属贸易公司和莫斯科国立冶金工厂设计院共同对苏联的金属积累作了统计和研究。 1928年,美国便成立了“废钢铁协会”(ISIS)和“回收工业联合会”。创办了《废料时代》和《今日回收》月刊。还设立了“废金属研究和教育基金会”。 1930～1940年间,美国矿冶工程师学会的著名刊物《钢铁工程师》连续数年刊载了有关废钢铁加工和利用的论文和报导。
Research on scrap steel abroad has generally started from the beginning of this century. As early as 1900, the American Iron and Steel Institute and the Butler Institute separately estimated the U.S. metal holdings. In 1926, the author of the book Rust in the United States and Its Causes and Causes published in the United States estimated the metal accumulation in the United States in 1924 to be 457 million tons. In the same year, the former Soviet Union’s ore metal trading company and the Moscow State Metallurgical Factory Design Institute jointly counted and studied the metal accumulation in the Soviet Union. In 1928, the United States set up the “Iron and Steel Institute” (ISIS) and the “Federation of Recycling Industries.” Founded the “Waste Times” and “Today’s Recycling” monthly. Also set up a “scrap metal research and education foundation.” Between 1930 and 1940, the well-known publication “Steel Engineer” of the American Society of Mining and Metallurgists published papers and reports on the processing and utilization of scrap steel for several consecutive years.
