ALUMINIUM FOUNDRY

Degasser

Degasser 190

A range of chemical degassing and degassing cum grain refining agents for aluminum and its alloys.

General Description

DEGASER products are compacted tablets in different sizes to facilitate treatment of various melt sizes. They are plunged into aluminium melts for degassing.
Even under the best melting conditions, it is often impossible to prevent hydrogen gas from entering the melt which finally gives rise to porosity in the cast products. It is therefore necessary to remove as much of hydrogen from the melt as possible prior to pouring.
DEGASER range of products remove the dissolved hydrogen by diffusion process. Degassing with these products is superior to flushing with chlorine gas which is associated with problems of space, equipment, corrosion, health hazards, etc. Some of the degassing products contain grain refining elements also and these products function as combined degassing and grain refining agents.

Application

  • Application rate ranges from 0.15 to 0.3% depending on the melt charge
  • Plunge the recommended quantity as per the application guide to the bottom of the melt using a preheated cylindrical or rectangular basket type plunger when the temperature is falling. The degassing should be continued until the bubbling ceases
  • Coat the plunger with a refractory coating to prevent iron pick up. Dry the plunger completely before use
  • Remove the wrapper before the DEGASER tablets are plunged, otherwise metal may pick up hydrogen from the decomposition products of the wrapper. Do not expose DEGASER tablets to atmosphere as far as possible as moisture pick up would result
  • As a gentle rolling action creates more efficient degassing than a turbulent action, apply DEGASER tablets in two or more successive operations rather than in a single operation
  • In case of Al-Si Hypoeutectic and eutectic alloys, degas before modification treatment. This helps in securing a constant degree of modification by destroying any existing modification and then remodifying to a known and desired extent
  • In case of AI-Si hypermetric alloys, degas before and after grain refining treatment. This helps in knocking off sodium present in the melt before grain refinement and in getting better dispersion of the primary silicon particles after grain Refinement

Degasser N2 (Nitrogen Based)

Degasser N2 : Nitrogen Based Degassing Tablets

General Description

Degaser-N2 is an environmental friendly range of chemical degassing tablets for aluminium and its alloys. Degaser-N2 is used to remove dissolved hydrogen gas by diffusion process.
Even under the best melting conditions, it is often impossible to prevent hydrogen gas from entering the melt which finally gives rise to porosity in the cast products. It is therefore necessary to remove the hydrogen from the melt to avoid any such problems in the cast or final section. Degassing with these products is superior to flushing with chlorine or nitrogen gas which is associated with problems of space, equipment, corrosion, health hazards, etc.
Degasser N2 Tablets are environmental friendly and do not produce any smoke, fumes or smell during degassing.

Application

  • 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 put into maximum temperature and when the temperature is falling.
The application techniques using plungers simply require that the tablet is immersed using bell plunger to the bottom of the melt.

Since the efficiency of the operation depends upon the time of contact between bubble and metal, it is essential to immerse the tablet as deep into the melt as practicable and hold it there until bubbling has ceased. Plungers should be pre-heated and dried.

Gentle rolling action creates more efficient degassing than a turbulent action; apply degaser 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.

Nucleant 2 (Grain Refiner)

Plunge able grain refining tablets for aluminum alloys

General Description

NUCLEANT range of products are available in tablet form and are used for grain refining of aluminium and its alloys.

Normally, aluminium and its alloys solidify with coarse columnar and equated crystals. Such a coarse grain structure poses problems like poor feeding characteristics, cracking during metal working and poor response to the surface treatment processes. Nucleant 2 is an excellent grain refiner.

In the case of hypereutectic aluminium-silicon alloys the primary silicon precipitates in coarse particles which tend to cluster. This leads to poor feeding characteristics and lower tensile strength and wear resistance properties. Nucleant 2 is used for grain refinement of such alloys. NUCLEANT addition into the metal before the casting operation overcomes these problems by producing fine equiaxed grains in the case of aluminium and its alloys.

Application

Instructions for use :

Melt under the cover of a suitable flux and bring the metal temperature to 730C - 750C for aluminium and its alloys. In case of hypereutectic Al-Si alloys, bring it to the desired temperature depending on the size of the casting.

When the metal temperature is falling, plunge the recommended quantity (as per the application guide) of NUCLEANT right up to the bottom of the melt. Use a perforated and preheated bell plunger coated with refractory coating for plunging to prevent contamination of the melt with iron. In case of Al-Si hypereutectic alloy, degas the metal before treating with NUCLEANT to knock off sodium in the metal.

When the reaction ceases, degas the metal with the help of a suitable DEGASER * product, dross off and modify wherever required (in the case of hypereutectic and eutectic Al-Si alloys).

Advantages:

  • Improves mechanical properties
  • Improves feeding characteristics
