Vertical upward casting

There was equipment for vertical upward casting for faster manufacturing of thin bars or wires implemented in the 90s of the 20^th century. This method is being basically used for manufacturing products of 8-30 mm diameter.

Vertical upward casting is put into use by casting of bronze, copper, nickel alloys, because it has been found out that by casting these alloys vertically up the casting speed is higher and the physical properties of the gained alloys are better. The main advantage of this method is the possibility to change fast the crystallizer, to cool it and to warm it up of necessity.

The drawing illustrates the vertical upward casting. The main components are: melting furnace or transportation ladle, casting furnace with tundish, crystalliser with isolation material, cooling system and installed graphite mould, secondary cooling, roll support and saw.

The equipment functions as follows: first the metal is molten in the melting furnace and tapped into the ladle for transportation to the casting furnace or given directly into the tundish of the casting furnace. From the tundish the hot metal flows under the influence of interconnected containers trough the graphite mold, installed in the crystallizer vertically upwards, where metal is being cooled and gains definite form. The roll supports catches up the product and adjusts the casting speed. The product comes out of the casting machine vertically. With a moving circular saw the product is being cut into predefined length and after that passed on for further processing.
