Abstract

The paper presents basic features of the application of active gas atmospheres in heat treatment furnaces. Disadvantages of these atmospheres are that they provide only partial protection of the steel surface and that they are not environmentally friendly as they spend the limited sources of natural gas and also emit environmentally harmful gas compounds, such as carbon dioxide CO2 and nitrogen oxides NOx. In order to enable the full protection of steel parts in heat treatment, a system for forming a protective gas atmosphere containing noble gas; argon or helium, has been developed. These two gases provide the absolute protection of the surface and have no harmful effects on the environment.
