摘要
Steel is continuously cast in a mould comprising a grooved wheel (10) and an endless flexible belt (11) with cooling by sprays (S1 to S4). The casting and withdrawing of the bar and the cooling of the mould and bar are controlled to eliminate microsegregation in the bar and to provide a very uniform distribution of constituents and impurities, in particular oxygen, carbon, sulphur and manganese, in transverse section. The bar has improved properties for subsequent processing, in particular higher tensile strength. IMAGE
