Materials - MODIFYING INSETS FOR CAST IRON
Modifying element TU BY 100229713.003-2005 is designed for complex
out-of-furnace fluid iron processing when casting. The processing
includes "late" (in casting mold) fluid iron melt inoculation
by modifying element and also fine filtration by elements of fine
cleaning. A Unique composition of the additive and its insertion
method provide powerful grafitizing effect and different section
structure equalization of different-walled details and size-reduction
of melt structure constituents.
THE APPLICATION WITH silica fiber grids based filters
MI may be placed in a variety of ways but there is a rule that should
always be followed: filter elements are to be placed closer to the
casting and MI closer to the down-sprue if possible.
The modifying element consumption is 0.05 to 0.1% of specific quantity
of metal of the mold if combined with the ladle inoculation and
0.07 to 0.15% without the ladle inoculation. Casting temperature
should be no less than 13000C.
The types of modifying and filtering elements and variants of their
placement in the gating system depend on the chemical composition
of the alloy, the melting practice and out-of-furnace processing,
specific quantity of metal of the mold, the design of the gating
system (diameter of the down-sprue, sprue base and runners, mass
flow rate of metal pouring in the mould etc.
THE ADVANTAGES OF USAGE
- Opportunity of individual process technology for each cast, achieving
specific effects such as perlitezation, ferritization, heating,
increase of castability etc;.
- Maximum graphitizing effect;
- Minimum probability of nonmetallic inclusions;
- Economically efficient (compared to the conventional practices).
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.
ODO "Beltechnolit" is looking for regional representatives
in CIS, Europe, Asia, etc., welcomes other forms of collaboration
in the scope of foundry production distribution.
