Round Grain Refiner, For Industrial, Performance : Optimum

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.
