(据美国“金属市场”杂志1959年19期报导)美国共和钢铁公司试验室最近研究成功一种直接用铁矿粉轧带钢的连续生产方法,并已试制成带钢八百余公斤。此法的第一步是高纯度铁矿粉的还原;第二步用轧辊将铁粉挤成半固体状金属带。金属带随即穿过一具有还原气氛的炉子(炉温约1,200℃),再经一列带钢轧机热轧成所需尺寸的带钢,经过酸洗、冷轧和退火便卷成卷或切成板材。 (According to the “Metal Market” magazine 1959 19 report) United States Republican Iron and Steel Company Laboratory successfully studied a direct use of iron ore powder strip steel continuous production methods, and has been trialled into a strip of 800 kilograms. The first step of this method is the reduction of high purity iron ore powder; the second step is to roll the iron powder into a semi-solid metal strip. The metal strip is then passed through a furnace with a reducing atmosphere (furnace temperature of about 1,200 ° C), hot-rolled to the desired size by a strip mill and rolled or cut into pickles, cold rolled and annealed Plate.
