Solutions

Production Volume Increase (Enhancement of Productivity)

Suitable power patterns by scrap, power, fuel additive and time slot can be pursued through the operational data analysis function, which is based on the pattern power control function and additional scrap charge/melt down determination control.
Flicker control and power demand control can also be provided.

Production Cost Reduction

The reduction of power and refractory consumption can be achieved through hot spot control, slag foaming guidance, heat loss analysis and other functions distinctive to the AUTO-ARC.

Customization

Records of each heat event, power/auxiliary fuel/auxiliary materials, analytical values, etc., are collected, and data for more than 10,000 charges are kept.
A diverse range of functions for the improvement of operations are provided, including reporting functions for operational logs, daily logs, and monthly logs as well as statistical analysis functions to support the evaluation of operations from past performance data.
