Chlorine Free Degassing tablets for Aluminium
General Description:
ECO – DEGAS (NITROGEN) is an environmental friendly range ofchemical degassing tablets for aluminium and its alloys. ECO – DEGAS (NITROGEN) isused to remove dissolved hydrogen gas by diffusion process.
Even under the best melting conditions, it is often impossible to prevent hydrogen gasfrom entering the melt which finally gives rise to porosity in the cast products. It istherefore necessary to remove the hydrogen from the melt to avoid any such problemsin the cast or final section. Degassing with these products is superior to flushing withchlorine or nitrogen gas which is associated with problems of space, equipment, corrosion, health hazards, etc.
- ECO – DEGAS 200 : DEGASSING FOR ALUMINIUM
- ECO – DEGAS 190 : DEGASSING + GRAIN REFINING FOR ALUMINIUM
- ECO – DEGAS N2 : NO FUME + NO SMELL DEGASSING FOR ALUMINIUM
Advantages :
- Removal of Hydrogen from the melt
- Environmental friendly method of degassing
- Minimization of porosity, and defect free casting
- Easy to use without any storage and handling problems
- No impurity added into the melt
Instructions for use :
The most efficient degassing techniques are carried out on metal which has been putinto maximum temperature and when the temperature is falling.
The application techniques using plungers simply require that the tablet is immersedusing bell plunger to the bottom of the melt.
Since the efficiency of the operation depends upon the time of contact between bubbleand metal, it is essential to immerse the tablet as deep into the melt as practicable andhold it there until bubbling has ceased. Plungers should be preheated and dried.
Gentle rolling action creates more efficient degassing than a turbulent action; applydegaser tablets in two or more successive operations rather than in a single operation.
Degassing should be continued till bubbling ceases.
Note:
The use of DEGASSING may result in small amount of fume evolution. This is non-toxic,
no odor and it will not create any problem to the environment.
