Competitive Edge

Rongxing Electrode Paste delivers stronger performance through optimized formulation, automated production, stable capacity, and source-factory cost control.

01

Product Advantages

  • Improved electrode paste formulation helps reduce ash content and increase strength, lowering consumption during use.
  • Specific consumption performance is better than that of world-leading brands.
  • Rongxing electrode paste uses authentic Ningxia Taixi anthracite coal, which features low volatile matter, low ash, high carbon content, low resistance, and high strength.
  • Large-scale output helps reduce purchasing and management costs per ton, making the product more cost-effective.
02

Production Advantages

  • Fully automated production lines precisely control raw material ratios, keeping volatile matter deviation within 0.1%.
  • Daily production capacity reaches 600 tons, supporting stable supply for bulk orders.
  • In 2008, RMB 28 million was invested in CNC equipment upgrades, reducing feeding error to within 2 kg.
  • Current annual capacity reaches 200,000 tons. With the new Lianyungang plant adding 100,000 tons per year, total annual capacity will reach 300,000 tons.
03

Cost Advantage

As a source manufacturer located in a metallurgical raw material industrial base, Rongxing can effectively control production costs from raw material procurement to manufacturing.
