Digital Electronic Regulation in India

Tenova has successfully commissioned its new Digital Electronic Regulation system combined with the hydraulic HRR2 servo-valves for Höganäs, India.

Tenova has successfully commissioned its new Digital Electronic Regulation (TDR-H) system combined with the hydraulic HRR2 servo-valves for Höganäs India Pvt. Ltd, Ahmednagar, India. This company is part of Höganäs AB, a world leader on the market for iron and metal powders, headquartered in Sweden.

Tenova full-digital, high-frequency, PC-based arc regulator TDR-H (Tenova Digital Regulator with Harmonics detection and control) and High-Response servo-valve HRR2 (High Response Regulator) advantages are: the stabilization of fast arc, the increase of active power, the reduction of power-on time,  and the control of foamy slag control.

In particular, the improvement of the arc stability, allowing the furnaces to operate at higher active power rates to reduce the power-on-time and increase efficiency, allows savings in the consumption of electric energy as well as in electrode consumption and breakages.

Expectations on performance have been fully satisfied with the Höganäs project and in the future, Tenova is looking to expanding its collaboration with other Indian steelmakers. 

Tenova automation solutions are based on Industry 4.0. The latest release, called TDR4.0, includes now advanced diagnostics for the whole regulation chain (including analysis of the position feedback from proportional valves and from the electrode masts), predictive maintenance and self-trimming, as well as a fully customizable interface.

Thanks to the last 20 years on EAFs and LFs installation in more than 200 plants, the features of Tenova digital regulator have been updated and upgraded during the years, to give the most advance and reliable solution in regulation.
