Boron is used in aluminium and its alloys as a grain refiner and to improve the conductivity by precipitating vanadium, titanium, chromium, and molybdenum. All of these are detrimental to the electrical conductivity at their usual impurity levels in commercial grade aluminium. Boron can be used alone (at levels of 0.005 to 0.1 %) as a grain refiner during solidification, Use of CERALOY-B is far more environment friendly than the conventional salt based refiners. Since no chemical reaction is involved, crucible life can be improved.

It is a micro structural activity in which as cast growth of fine, equiaxial grain while    solidification is observed. Several factors affecting this activity are solidification time, pouring temperature, agitation during solidification, degree of metal superheat. Because it is not easy to control these factors while production, the most easy and effective way of grain refinement is deliberate addition of grain nuclei in the melt, which facilitates the homogeneous distribution of silicon grains in all kind of alloys. For such addition, combination of titanium & boron is proven to be the best nuclei. There are two types of grain refiners on the salt base compacted tablets containing titanium and & other is titanium and boron.

In casthouse applications, the control of grain size is essential in maintaining product consistency and quality, in reducing cost and maintaining high levels of productivity. Controlled addition of Al-TiB master alloy in aluminum releases nucleating particles that promote equiaxed, fine grained structures in cast alloys, thus redistricting formation of columnar crystals. Al-TiB grain refiner alloy improves homogeneity and allows uniform distribution of alloying elements, reduce porosity and eliminate hot tearing in cast structures, improves responsiveness to subsequent heat treatment and enhance mechanical properties and machinability in the fabrication process.

Sefrefiner is normally sold in capsules of 25 & 50 grams. It is a whitish Powder packed in Aluminum Sheet. Consumption : 200 grams of Sefrefiner is recommended per metric ton of melted brass to be inoculated. This equates to one 50 gram capsule for each 250 kilograms of melted brass. Alloy Requirements : Best casting results will occur with clean yellow brass ingot. Otherwise the basic Scrap Brass must be free of inclusions which are identified by a visual check of the polished surface. Good grain refinement usually occurs when the copper content is between 56 and 62 percent. Optimal grain refinement usually occurs when the copper content is 59.5 percent the aluminum content is 0.6 percent. Sefrefiner has been used to lower the casting temperatures and increase the castability and fluidity. Method Of Use :As a safety precaution, care should be taken to preheat the Sefrefiner capsules on the furnace rim, shelf, etc. so they are free of any moisture. Any adjustments to the Aluminum or Zinc content of the melt should be made prior to adding Sefrefiner. The surface of the melt should be reasonably free of slag. Sefrefiner should be added to the melt by immersing the capsules about 50 cm-75cm (approx 25 inches or 2 feet) below the liquid metal surface using a bell shaped plunger. Expected Benefits : Depending on the alloy composition, the use of Sefrefiner can result in the following casting benefits:  Improved fluidity of the metal to be cast. Lower casting temperatures are possible depending on the size of the part to be cast and the type of mold to be used. Cracking tendencies of the parts to be cast are greatly reduced and most often, cracks are eliminated. The occurrence of Sinks/Misruns/Cold Shuts are greatly reduced. Lead is more uniformly distributed in the fine grain structure of alloy. Monetary Savings : Using Sefrefiner can result in the following savings:   Cost of purchasing fine grained ingot gets reduced. Casting scrap is reduced. Finishing and rework costs are reduced. Energy is saved resulting from lower casting temperatures.
