Siemens VAI starts up vertical slab caster at Baosteel, China - Casting of highest alloyed-steel grades for special-product applications

摘要

In the Spring of 2009, Siemens VAI Metals Technologies started up and commissioned a new vertical slab caster at Baosteel's Special Steel Branch in Shanghai, China. This solution enables a wide range of highly critical steel grades to be continuously cast, which would otherwise not be possible to produce in a conventional bow-type caster. Due to the special design features of the machine and the installation of a full array of technological packages, slabs are produced with the highest surface and internal quality. Steel production in the existing ingot casting route could also be partially substituted with the new caster.
