用液体金属在两个辊子中间直接铸造连续铝带的主张是弗鲁格铝箔加工厂在1958年提出的。目的是对轧制箔材造成的废料进行再循环,这些废料约占加工金属总重量的20％。在十五年中,Scal不断改造这种设备,最后在1973年制造出卷材坯料机,其坯料宽1600毫米,厚8毫米,生产能力是每小时一吨(当宽度为一米时)。另外,对于那些中型加工企业来说,废品的循环使用问题、最初的低投资问题以及 The idea of ​​casting a continuous strip of aluminum with liquid metal directly between the two rolls was proposed by the Fruego aluminum foil processing plant in 1958. The purpose is to recycle waste material from rolling foils, which account for about 20% of the total weight of the processed metal. For 15 years, Scal continually rebuilt this equipment. Finally, in 1973 a coiler was manufactured with a billet width of 1,600 mm and a thickness of 8 mm. The capacity was one ton per hour (when the width was one meter). In addition, for those medium-sized processing companies, the recycling of waste products, the initial low investment and
