Method and apparatus for casting ferroalloys and slags in moulds having a large ratio of mould mass to cavity size

摘要

A method and apparatus for continuously casting small shapes of ferroalloys, slags and like remelt metals in multi-cavity iron or steel moulds wherein the mass of the mould is about 6 to 25 times greater than the mass of the castings. The molten metal or metallic slag is poured into the moving train of moulds which have been previously spray coated with a refractory slurry. The moving train of moulds is subjected to water sprays shortly after pouring to quench the castings and to stabilize the mould temperature below 500 DEG C. High production yields and improved mould life are obtained.
