Situation
Chlorine gas and/or chlorides are used as fluxing agents in aluminium furnaces for the purpose of reducing alkali contents.
Problem
Chlorine gas is considered a hazard to the environment. It is most desirable to either reduce its use or eliminate it.
Solution
STAS has developed rotary flux/gas injectors which use either salts or a reduced amount of chlorine gas, together with nitrogen as a carrier gas. Flux is non-hazardous to the environment and reducing chlorine gas is desirable.
Advantages
- Reduces alkalis.
- Reduces inclusions.
- Reduced HCl and dust emissions.
- Stirring action ensures temperature and alloy homogeneity.
- Replaces and/or reduces chlorine gas in holding furnaces.
- Various models (fixed or mobile) available to suit client needs.
