Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. The metal sintering process turns a mix of iron ores, return ﬁnes, ﬂuxes and coke into pellets which are fed into a blast furnace that transforms the materials into a high quality steel.
Umicore’s DNX® catalyst is responsible for reducing harmful emissions in the hot waste gas resulting from metal sintering. With extensive experience in supplying catalyst systems for sintering plants, Umicore has the ability to provide catalyst that meets or exceeds design lifetimes despite the heavy metals found in the waste gas, such as Chromium and Arsenics, which are highly poisonous to catalyst.
