Rotary kiln chains

Specification of materials The correct choice of the material is a main criteria for the efficiency of the kiln. Especially important for the selection of the materials are: Temperature, type of firing and type of gases. All given analysis correspond to DIN. There can be deviations in the chains we deliver. Carbon and alloy steels For the section below 500° C. In case of higher wear, alloy steels are recommended. These steels can be heat treated in order to obtain a harder surface and therefore, lower wear. Ferritic steels These steels fit best to sulphurous gases, but do not suit for nitriding and for carburizing conditions. Austenitic steels They are most suitable to carburizing conditions, but unsuitable for gases with more than 1% sulphur. Austenitic-manganese steels Combines the advantages of the both mentioned steels, these steels are suitable for sulphur containing gases with carburizing conditions.
