Abstract
The latest generation Danieli continuous casting machines feature a broad range of advanced technological tools, focused on production of high-quality large, medium and small-size special steel blooms. In relation to blooms size or type of steel, different Technological Packages are made available, all with the common goal of obtaining top final product quality and best CCM machine performances. This article introduces the operative results in the field of special steels like free- cutting steels, micro-alloyed steels for automotive industries, bearing steels. More specifically, reported data refers to following casters: 2-strand special steel caster for large-size blooms completely re-constructed by Danieli at SeAH Besteel, Korea. The machine casts 390x510-mm blooms of special steels, as spring steel, bearing steel, free cutting steel, boron steel, high tensile strength steel, alloy and carbon steels for machine and structural use. It features, among other, Dynamic Soft Reduction system and Quench Box system. With a speed up to 0.66 m/min, the machine is capable to reach almost 100000 tons per month. 5-strand special steel caster for small-size blooms successfully started up in early 2005 at Corus Engineering Steels’ Aldwarke Steel Works in Rotherham, UK The 10-m-radius machine, with a casting speed of 1.9 m/min for 180sq. and 1.4 m/min for 210sq. grants a 140-tph output based on:
