PREPARATIONS FOR TREATMENT OF ALLOYS ON THE BASIS OF ALUMINIUM - Materials - www.beltl.ru






Materials - PREPARATIONS FOR TREATMENT OF ALLOYS ON THE BASIS OF ALUMINIUM

THE DESCRIPTION

At present only high-quality castings meeting the physicotechnical requirements of the consumer are demanded in the market. Any ineffective production methods involve loss in quality of casting, provoking various kinds of waste (porosity, nonmetallics, the inferior mechanical properties, insufficient surface smoothness, etc.). Production of competitive high-quality casting is impossible without application of highly effective procedure on the basis of complex preparations. In this connection a series of ecologically safe preparations of different function for volume and a surface treatment of alloys on the basis of aluminium, zinc and other alloys has been developed.

Complex treatment of alloys with tableted preparations together with flux compositions is an effective element of procedure of decrease of oxides and hydrogen content in melt, high-quality modifying of non-ferrous melts and solving other problems.

THE LIST OF PREPARATIONS FOR TREATMENT OF NON-FERROUS ALLOYS

THE APPLICATION

For achieving maximum refining and modifying effect complex melt treatment by flux compositions and corresponding tableted preparations is recommended. In cases their joint use is impossible or inexpedient powder and tableted preparations may be used separately.

Usually the melt is brought to necessary temperature and rated amount of powder flux is spread over the surface of melt and actively mixed into it. Tablet is introduced into melt by an immersion bell. The preparation is brought down to the bottom of the ladle and rotatory movements with the bell are being performed while boiling of metal (5-7 minutes) continues. After the treatment a pause of 3-10 minutes is kept before slag is flushed.

ADVANTAGES OF USAGE

  • high efficiency;
  • improvement of a number of mechanical and technological properties of the metal;
  • cost-effectiveness at stable high quality, low consumption, low cost etc.;
  • affordability and simplicity of application;
  • ecological safety;
  • " substantial economy of metal (30kg/ton).

Packing: Tablets: twofold cardboard boxes with polyethylene interlayer containing from 30 to 1000 pieces. Flux: plastic bags 0,5-2 kg each packed in cardboard box or paper bags 25 kg each on pallets wrapped in film.

If you are interested in introduction of highly effective processes of treatment of cast irons and non-ferrous melts collaborators of our enterprise are ready to render consulting and technical support including a business-trip onto your enterprise with a test batch of necessary materials. This service is given at a no cost.
