Technical Specifications

Why Choose Our Direct Current Furnace Technology?

Superior Energy Performance

Your production costs will decrease significantly with our advanced electric arc furnace design. The stable arc technology ensures 10-15% better energy efficiency compared to conventional AC systems. You'll experience uniform heating throughout the melting process, resulting in consistent steel quality and reduced energy waste.

Cost-Effective Operation

Our direct current technology dramatically reduces electrode consumption, saving you substantial operational expenses. The high power factor minimizes grid impact, eliminating the need for additional reactive power compensation equipment. This translates to lower utility costs and improved electrical system stability.

Advanced Metallurgical Control

The centralized arc design provides exceptional temperature control and composition uniformity. Your steel quality will improve through electromagnetic stirring effects that homogenize the melt without external gas injection. This results in superior casting quality and reduced material waste.

Robust Construction Features

Water-cooled furnace walls ensure uniform heat dissipation and extended equipment life. The simple structure design facilitates easy operation and maintenance, reducing downtime and training requirements. You can also equip your system with scrap steel preheating devices for enhanced thermal efficiency.
