Aluminium grain refiner manufacturer in India
General Description:
ECO – GRAIN REFINER 2 range of products are available in tablet form and areused for grain refining of aluminium and its alloys.
PURPOSE:
Normally, aluminium and its alloys solidify with coarse columnar and equiaxedcrystals. Such a coarse grain structure poses problems like poor feeding characteristics,cracking during metal working and poor response to the surface treatment processes.ECO – GRAIN REFINER 2 is an excellent grain refiner.
- ECO – GRAIN REFINER 2 : SALT BASED GRAIN REFINING TABLETS
- ECO – GRAIN REFINER 11 : PHOSPHORUS BASED GRAIN REFINING FOR HIGH SILICON ALUMINIUM ALLOYS.
- ECO – GRAIN REFINER N2 : ECO – FRIENDLY GRAIN REFINE WITH NO SMOKE NO SMELL
In the case of hypereutectic aluminium-silicon alloys the primary silicon precipitates incoarse particles which tend to cluster. This leads to poor feeding characteristics andlower tensile strength and wear resistance properties. ECO – GRAIN REFINER 11 is usedfor grain refinement of such alloys
ECO – GRAIN RFINER addition into the metal before the casting operation overcomesthese problems by producing fine equiaxed grains in the case of aluminium and itsalloys.
INSTRUCTIONS FOR USE:
- Melt under the cover of a suitable flux and bring the metal temperature to 7300C -7500C for aluminium and its alloys. In case of hypereutectic Al-Si alloys, bring it tothe desired temperature depending on the size of the casting.
- When the metal temperature is falling, plunge the recommended quantity (as perthe application guide) of ECO – GRAIN REFINER right upto the bottom of the melt.Use a perforated and preheated bell plunger coated with refractory coating forplunging to prevent contamination of the melt with iron. In case of Al-Sihypereutectic alloy, degas the metal before treating with ECO – GRAIN REFINER11 to knock off sodium in the metal.
- When the reaction ceases, degas the metal with the help of a suitable ECO -DEGASER* product, dross off and modify wherever required (in the case ofhypereutectic and eutectic Al-Si alloys).
