日本以崎炼铁公司应用急冷凝固技术,将熔化的钢水直接制成厚度约0.3毫米的薄钢板。这项新技术不需要大规模的生产设备,省略了钢坯的连续铸造、热轧和冷轧生产工序。该公司用这项新技术试制成功含硅量为4.5％的硅钢板样品,目前正在研究用这项新技术生产硅钢和铁钨合金钢薄板(作为电子材料),以期实用化,并进一步开发 Japan to Kawasaki Iron Corporation rapid solidification technology, the molten steel directly into the thickness of about 0.3 mm thin steel plate. The new technology does not require large-scale production equipment, omitted the billet continuous casting, hot-rolled and cold-rolled production processes. Using the new technology, the company successfully prototypes silicon steel samples with a silicon content of 4.5% and is currently working on the production of silicon steel and iron-tungsten alloy steel sheets (as electronic materials) with this new technology for practical use and further development
