Types of Casting Defects | Metals | Industries | Metallurgy
Some of the casting defects are described below: 1. Surface Roughness: Too coarse a moulding sand or when pouring temperature is high leads to rough or pebbly surfaces on castings. In steel castings, roughness is produced due to occurrence of surface reaction at mould-metal interface in which iron is oxidised and iron oxide reacts with silica to forms rough compound. [...]
