  • Continuous chain caster and method
    Publication number: 20030205356
    Abstract: A continuous chain caster has upper and lower mold assemblies comprising endless belts and chains traveling at synchronized speeds. The mold assemblies meet to form a mold channel which is filled with molten metal from a headbox and feed tip. As the molten metal passes through the mold channel, the metal solidifies into the shape of the mold channel. Each belt is positioned outside the corresponding chain so that the smooth surface of the belt defines the surface of the mold channel thereby preventing the formation of fins between mold blocks which make up the chain, protecting the chain blocks, and neutralizing deformations in the chain blocks. The upper and lower blocks of the chains have protrusions at opposite ends which engage the opposing blocks to form the sides of the mold channel. By sliding the chains relative to each other, the width of the mold channel is adjustable.
