The company Stalprodukt SA. at Bochnia, Poland has awarded LOI Thermprocess a contract for a new batch type annealing plant for grain oriented silicon steel. The new LOI furnaces replace the existing vacuum furnaces to increase the production capacity with significant reduction of maintenance costs.
The plant will have an annual capacity of 22,000 t. It is to be designed for a maximum outside diameter of 2,200 mm, a maximum coil weight of 20 t and a maximum strip width of 1,150 mm.
The LOI Multi-Stack Batch Type High Temperature Annealing Plant exists of 8 bases, each designed for 4 stacks. Each plant runs under a very high annealing temperature of nearly 1,200 °C and is equipped with controlled rapid cooling devices.
The reached magnetic properties like core loss and permeability of magnetisation allow using the annealed material for highest efficiency power transformers.
The scope of supplies under the contract also includes a control and information system and the ProView supervisory control system for fully automated, computer-aided heat treatment.
Commissioning is scheduled for May 2006.
