We are delighted that our customer "Rudolf Rieker GmbH" has won the Environmental Innovation Award from the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMVU for short) for the steel hardening process we have developed with ultra-low temperatures of down to -80 °C.
In addition, this process is environmentally friendly and does not require the considerable amount of energy in production, transport and storage as the current industry standard.
Here, our solution can save between 50% and 70% energy compared to conventional processes with the same quality.
Currently, in a cryogenic treatment process of steel, liquid nitrogen is sprayed into a cold chamber and heated in the same furnace. This means that the entire mass of the furnace is always re-tempered. Our process uses a separate furnace for cooling and recovers the cold energy from the finished batch. We also use the MC22 O/W cold air chiller from Mirai Intex instead of liquid nitrogen, which is many times more efficient than nitrogen at these temperatures.
According to Christian Kühn, Parliamentary State Secretary at BMVU, this subsidised process can make an important contribution to reducing greenhouse gases and avoiding nitrogen emissions.
