日本川崎制铁公司成功地开发了厚30μm(0.03mm)、宽1m 的超薄宽幅不锈钢箔片,并将自今年秋季投放市场。除不锈钢外,该公司还正在从事镍合金、普通钢等类金属箔片的开发,旨在开拓历来与铁无缘的新的应用领域。极薄而平展地轧制不锈钢之类硬金属,从来被认为是困难的,一般厚度30μm 的箔片幅宽只有50～60cm,便达到正式的商品化规格了。但该公司为冲出钢铁业不景气的重围,作出 Japan’s Kawasaki Steel Corporation has successfully developed ultra-thin, wide-width stainless steel foil with a thickness of 30μm (0.03mm) and a width of 1m, which will be put on the market this fall. In addition to stainless steel, the company is also engaged in the development of nickel alloy, ordinary steel and other metal foils, aiming to open up new applications that have traditionally not been associated with iron. Rolling hard metals such as stainless steel very thinly and flatly has never been considered difficult. Generally, the width of a foil with a thickness of 30 μm is only 50-60 cm, and it has reached the official commercial specifications. However, the company made a breakthrough in the slump of the steel industry.
