Particularly efficient cleaning takes place by the introduction of an inert gas into the melt. For this purpose, ladles or casting furnaces with specially designed rinsing stations are equipped with corresponding injection systems. Impeller systems consisting of a rotor system which is placed on the vessel and in which the gas is transported via a hollow shaft to the rotor where it exits into the melt in the form of very fine bubbles, are preferred. The rotary movement optimally distributes the gas, and the melt is homogenised.
In addition to the gases required for your process, Messer offers a variety of equipment for its optimisation under the brand names Oxipyr and Oxijet.
In order to select the optimum system, experts from Messer first carry out a comprehensive process analysis. Following calculations and basic engineering, suggestions are made for optimisation and further procedures.
Oxijet - Lance Technology
The gas input system must be specific to the vessel. Various nozzles can be used for this purpose:
- Messer Oxijet - basic
- Messer Oxijet - swirl
- Messer Oxijet - supersonic
- Messer Oxijet - atomising
Oxijet – basic lance with graphite coating
If necessary, the lances are equipped with water cooling or graphite jackets.
Messer only offers complete solutions for impeller systems in cooperation with partners.
