Sinterofen IR SARNES Type 620/IR/QC/G
furnaces for heat treatment • Industrieofenbau
Located near Stuttgart in the SouthWest of Germany, SARNES ingenieure GmbH & Co KG is manufacturer of industrial furnaces. Since 1980 we have been building and developing conveyor belt sintering furnaces and protective gas systems for line-production in the powder metallurgy industry. With 120 employees on production locations in Stutensee, Thale, Biberach and Schwendi, we are proud partner of the Elektromatic Projekte GmbH since 2015.
The optimisation of combustion processes, burner development and gas-fired conveyor belt sintering furnaces, heat and material conveyance (open reaction spaces, gastight muffle furnaces) in manufacturing plants and an analytical and empirical understanding of furnace atmospheres are basic features of our work and our systems. Our product range has seen continuous growth, side by side with our customers’ requirements and parts spectrum.
The range of electrically and gas-fired conveyor-belt sintering furnaces is from experimental size of 125mm up to high capacity of 24 tons/day with 1200 mm belt width and is designed for sophisticated applications upto 1350°Celsius.
CO2 neutral in the shortest possible time?
How can it be implemented in production and can the sometimes particularly energy-intensive heat treatment in industrial furnaces make a decisive contribution to this?
With the increasing profitability of hydrogen as an energy carrier, sintering, hardening, tempering and steam treatment furnaces can be operated in a CO2-neutral manner. Hydrogen-heated flow systems from SARNES are already in production. Multi-stage heat recovery in the high temperature range, regulated forced convection to improve the heat transfer in the medium temperature range of the heat treatment also enable CO2 and cost savings for external applications.
For a long time we have used 100% hydrogen not as a reaction gas only. The latest generation of SARNES continuous furnaces for heat treatment, sintering, hardening, annealing and burning out can be operated CO2-neutrally today with some upgrades. The SARNES burner family RSH and WSH can already be used for hydrogen operation. CO2-neutral production during sintering is feasible.
