Optimised energy consumption in continuous casting lines

FURNACES are crucial equipment in Upcast continuous upwards casting lines, to ensure a high-quality process and end product. They also play a key role in energy consumption; optimised use of energy decreases heat loss and production costs. Energy consumption is the largest individual cost factor in production. Typically, it is around 58 to 67 per cent of the overall costs. What impacts consumption are the furnace type and the inductor attached to it, as well as the lining materials. With the right combination, energy consumption can be minimised. “It is essential to choose the right combination suitable for each product and capacity,” said Janne Hosio, sales manager at Upcast Oy. vary significantly, Upcast Oy has designed new sizes of furnace to meet the various needs of customers, and they can be used in combination with a range of different power inductors. Options include smaller furnaces for lower capacity requirements, and larger ones for higher demands. Upcast furnaces are equipped with energy-efficient inductors, and the power supply can be controlled steplessly, enabling any power range to be used efficiently. Using transistor converters instead of step transformers allows the use of precisely the amount of power As capacity requirements

required, which also reduces the amount of heat loss. The variation of temperature is reduced, which also saves energy. Upcast has long experience of casting lines, and its development work has been based on the actual values of existing lines, in order to develop a more efficient and wider product range. Upcast Oy will be participating in wire Düsseldorf 2020, on stand 09 C06.

Upcast Oy www.upcast.com Bows for all types of double-twist equipment The C2S service division of Sampsistemi supplies more than 600 adaptable bow designs to the market for all kinds of double-twist equipment. For smaller bunching units (400/560mm) to larger double-twist stranders for aluminium or copper cords (2,000mm), C2S can propose bows to ensure performance and optimised production. By moulding high-graded carbons, C2S also ensures the long durability of its bows, as well extended lifetime of the main equipment, preventing harmful vibrations from spreading to the main bearings housings. The technical definition of the bow design is always discussed with the end-user, in terms of expected production speeds, product size or wire path interchangeability. The C2S team works in close collaboration with cable makers (mostly maintenance teams) to harmonise guides or eyelets on different brands of double-twist equipment. Among C2S’s best sellers is the patented Greenbow2, a closed-bow design that allows up to 25 per cent energy savings on high-speed bunchers. Initially developed for automotive products but now extended to small control or robotics cables thanks to fully interchangeable wire paths, Greenbow2 is easy to maintain as it features a removable inner tube.
