Heat-resistant stainless steel G48 series

for furnaces

Indirectly-heated rotary kilns are used for a wide range of applications and have to meet the ever-growing and present-day, challenging processing requirements of the industry. The desire for maximum productivity, partly combined with exotic and aggressive feedstocks, requires a high knowledge and experience for choosing the most suitable material for the kiln. The requirements on rotary kilns are diverse. For each individual case various parameters must be taken into account. The combination of high temperature corrosion and creep can lead to irreversible damage of the tube and necessitate repairs and in the worst case into premature retirement of the component and thereby lead to loss of production. Rotary kilns made of centrifugally cast Centralloy® metal tubes from S+C have proven themselves as reliable selection for this application. At S+C, rotary kiln’s tube material selection is customized and enables adaptation to individual process requirements. This enables a trouble-free operation and a long service life of rotary kilns which is clearly superior to the service life of those made of sheet metal.
