Twin / Single LF and Treatment Stations

Tenova Ladle Furnaces enable precise control of the melt temperature and of the chemical composition to guarantee improvement of productivity, flexibility and quality.

Improving steel temperature and analysis control is a key aspect of the secondary metallurgy processes. Tenova Ladle Furnaces enable precise control of the melt temperature and of the chemical composition to guarantee improvement of productivity, flexibility and quality.

Tenova Ladle Furnaces are usually designed to increase the melt temperature up to 5 °C/min and they are equipped with a water-cooled roof of either direct or indirect suction (controlled atmosphere) type, as well with other related facilities, such as wire feeding machines and powder injection systems.

Tenova LF can be designed as a twin unit, in order to maximize productivity without sacrificing process quality, using a single transformer by means of swinging electrode arms.

Tenova LFs are available for sizes from 5tls to 350tls.
