Chamber furnaces for wire treatment Horizontal chamber furnaces from ILES are produced in two distinct series with maximum working temperatures of 500°C and 700°C. They are used for stress-relieving, tempering, structural hardening, ageing and annealing of non-ferrous materials.

Billet caster at JSW JSW Steel Ltd (JSW), located in Toranagallu in the state of Karnataka in India, has commissioned the first eight-strand billet caster on the Indian subcontinent with SMS Concast, Zurich (Switzerland), a company of the SMS group, Germany. The billet caster delivered by SMS Concast is part of JSW’s expansion programme ‘Cheetah’ which will bring the production capacity at the Vijayanagar works to 7million tpy. The billet caster comprises the technology and equipment for open and submerged casting. It is designed for a production capacity of 1.7million t of billets per year. The high-speed caster contains the convex mould technology, electro- magnetic mould stirring, hydraulic mould oscillation and the Conseal IV technology. The production process is directly tuned to the downstream wire rod and rebar rolling mills with hot discharging route. SMS Concast AG – Switzerland

The main characteristics of the furnaces are high thermal efficiency, achieved by thermal insulation with ceramic fibres in several layers at differentiated density, and mass-less wire heating elements placed directly in the air circuit. A vitrifying system, with the special design of the internal deflector and of the high-revolution fan for air circulation, maintain temperature uniformity of ±5°C inside the treatment chamber. The furnaces can be supplied with several options including a timer, safety protection against over heating, an automated thermal cycle – no operator required – and 4, 6, 8 or 12 post external storage units, with loading system and automated thermal cycles.
