Contiblu® SMC   soft magnetic components  - heat treating

Faris v. Seckendorff is our SMC expert and would be pleased to discuss whatever is of interest in the field of magnetic part production and soft magnetic composites -- ->


Located in Baden Baden 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. 


The optimisation of combustion processes, burner development and hydrogen ready gas-fired conveyor belt sintering furnaces, heat and material conveyance (open reaction spaces, ceramic or steel muffle furnaces) in manufacturing plants and an analytical and empirical understanding of furnace atmospheres are basic features of our work and our systems. 


The range of electrically and gas-fired furnaces for sintering, hardening, steam treating, SMC, annealing, debindering from 125mm bet width up to high capacity  of 24 tons/day with 1200 mm belt width and is designed for sophisticated applications up to 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.
