Materials - PREPARATIONS FOR TREATMENT OF ALLOYS ON THE BASIS
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
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.
