Applications  [ Return towards  Metallurgy ]

As one of the important process steps in metallurgy, the fusing of metals and additives is improved in quality and performance by the application of oxygen. The performance of the various melting furnaces can also be optimized and gain in flexibility with improved economy.

The ladle heating with oxygen is the optimal solution to the fast preheating of the metallurgical vessels with reduced energy costs.

Sintering provides the possibility, to combine almost any materials and their properties together into a composite material.

Cryogenic treatment after the hardening represents a proven and environmentally friendly process to eliminate the residual austenite and to increase the hardness.

The base material in the ferrous and non-ferrous areas is accompanied with undesirable impurities after the melting. As a remedy, a flushing process with inert gas can be employed downstream.

In the melting process of the induction furnace and crucible furnace, there can be chemical reactions on the bath surface. To prevent this, protective gases can be employed there.

Hardening is the generation of the hard structure (martensite) by the purposeful chilling from the quenching temperature.

The process temperature, the material and the surface requirements after the heat treatment, which are associated with the annealing process, determine the selection of the process gases.

To create functional layers in a thermochemical way, nitrogen and/or carbon, for example, are placed in the periphery of the materials.

In soldering processes, the surface activation can be realized by the effect of active, protective gas components without the employment of soldering flux.
