Ingot Casting:
Ingot casting is a conventional casting process for liquid steel. Ingot casting, once contributing to majority of steel production, today constitutes a small percentage of global steel production. In recent times, continuous casting of steel has replaced most of ingot casting of steel but ingot casting is still the only method of steelmaking for specific low-alloy steel and for special forging application where products of large dimension, high quality or small lot sizes are needed. Typical applications of ingot castings are shafts for power plants, turbine blades, conveying equipment, ship building, tool making etc.
Ingot casting involves molten steel to be poured down through vertical pipes made of refractory material to often bottom of the ingot. The quality of holloware used for pouring has a significant impact on the quality of steel. Raj Ceramics is a market leader in holloware products since 1990. The company has invested heavily into extrusion equipment and presses to ensure strict dimensional tolerances (which saves installation time and prevents any leaks). The product’s recipes and firing technique further ensure no NMP inclusion. Backed on its quality and innovation, Raj ceramics has been leaders in hollowware in India and exports to many continents including Europe, Middle East, Asia and Americas.
