Materials - MODIFYING INSETS FOR CAST IRON

THE PURPOSE
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.
