Innovative Solutions for Thermoprocessing Plants and Rotary Kilns - Refining premium-quality bulk materials with high-grade steels made by S+C
The Germany based Schmidt + Clemens Group manufactures tubes for indirectly heated rotary kilns exclusively in the centrifugal casting process. These extra durable rotary kilns are utilized in the industry for thermal processing of bulk materials, e.g. for the production of ultra-high-purity alumina, rare earths, inorganic color pigments and in the powder metallurgy for the reduction of refractory metals.
In contrast to longitudinally welded tubes made from sheet metal, rotary tubes made from Centralloy® centrifugal castings offer both: technical and economic advantages. Even in the high-temperature range up to 1250°C, these tubes offer an extremely high functional reliability for a long and trouble-free operation. Due to the excellent temperature stability of Centralloy® centrifugal castings, indirect heated rotary kilns made by S+C are also particularly suitable for sealed plants, e.g. for vacuum or inert gas operation. In addition, internal fixtures such as inlet screws, flippers, mixers and dams can also be inserted into the rotary tubes, on request. The significantly increased service life compared to conventional rotary sheet-metal tubes should be emphasized (depending on the application, a factor of 2-3 compared to sheet metal tubes).
For the production of ultra-high-purity aluminum oxides, also known as alumina, the patented special material Centralloy® 60 HTR has proved particularly effective. It forms a dense and firmly adhering Al2O3 protective layer, which protects the tube from oxidation and corrosion and thus effectively prevents contamination of the production material with chromium oxide particles.
Such rotary tubes are available in diameters between Ø50 and Ø1,350 mm and in lengths of up to 16 meters. We supply such tubes for existing rotary kilns of various manufacturers as well as for new kilns. Our specialists will be pleased to give you advice.
Pusher tubes, tube retorts, as well as parts made of corrosion- and heat-resistant static castings supplement S+ C’s scope of supply for the thermal process industry.
