一、概况 方坯、大钢坯和板坯的连续铸造近20年来已从实验和中试阶段发展成熟。日本和欧洲首先实现这项技术,并从改善质量,提高产量和利润而获益。然而所面临的是建设这样的工厂所需的巨额投资,限制了对该技术的兴趣。 一种新的铸造技术对是直接铸造工艺,也就是生产的铸造产品应接近下一工序产品的尺寸。如连铸板坯尺寸为8—10吋,热轧板轧制到0.05～0.5吋,因此直接铸造板坯应接近于热轧的尺寸和性能,所以可取消热轧
I. Overview Billet, large billet and slab continuous casting nearly 20 years from the experimental and pilot stages of development and maturity. Japan and Europe first realized this technology and benefited from improving quality, increasing production and profits. However, the huge investment needed to build such a plant is limited by its interest in the technology. A new pair of casting techniques is the direct casting process, that is, the cast product being produced should approximate the size of the next process product. Such as continuous casting slab size of 8-10 inches, hot-rolled plate rolling to 0.05 to 0.5 inches, so the direct casting slab should be close to the size and performance of hot-rolled, so you can cancel the hot-rolled
