Hindalco's refractory grade aluminas are suitable for shaped and unshaped refractory applications, enhancing flowability, workability, strength and thermal performance of the final product. Our alumina products provide a strong advantage due to their fineness and mixing properties, which ensure that the resulting product will have minimal pores as required in application. Refractory grade calcium aide and reactive alumina are designed to improve performance with respect to low water demand, setting characteristic and strength. Which enable refractory industries to get low moisture and high strength castables with controllable setting behavior for vibrational flow as well as self flow properties. Let us look at how Hindalco's aluminas enhance the value of the final product. The Castable is prepared by mixing a variety of ingredients, among which is the alumina powder and water. The alumina crystals are fine and flow easily, making inroads into gaps left by other ingredients, creating an even, smooth surface that's ideal for use in high temperature application. Use of water, which is an undesirable element in the final product, cannot be completely eliminated but gets significantly reduced while preparing the mix. Castable pours easily and speedily into a mold that in turn creates high productivity and castable installation. High alumina refractory in the form of precast shapes or monolithic when installed inside the furnace offer desired performance, efficiency and longevity and use high quality fine aluminas help to achieve very high thermal mechanical properties over full range of operating temperatures.
