With regards to the hot-rolling of parallel flange section (ex. H-beam, Channel), the authors have succeeded a new size-free-rolling method with highly accurate dimensions.
This rolling method is characterized by using adjustable width horizontal rolls of universal stands and web-height reduction rolling.
The universal horizontal roll width can be changed within 20 seconds and the web-height of the parallel flange sections can be reduced by max. 32mm in the mill line.
As the result, it becomes possible to roll the parallel flange sections with constant outer-depth and highly accurate dimensions.
These rolling technology has been applied for new H-beams in the Large Shape Mill of the Kashima Steel Works.
