Microstructure study on Al-Si bar produced by the new near shape casting technique

In order to reduce cost of producing metal ingot, namely aluminium from its molten state, a new near shape casting equipment has been designed and fabricated. In this new technique molten metal was poured from a moving tundish into a copper mould that can be tilted until 6 degree. The cooled water s...
