Abstract
The bell is coated with or partly consists of composite rolled steel jacket. Its hard zone is situated towards the exterior and its interior soft zone serves to assemble it by welding to the bell. The steel jacket is manufactured from an ingot having, between the two associated steels, a mixing chamber defined by sheets of metal for separating the two associated steels from the composite cast steel.
