2×35 V/5500 A IGBT DC Power Supply in TISCO Stainless Steel Electroplating

Industry: Steel & stainless steel electroplating  |  Site: electroplating workshop, China Baowu Steel Group  |  Product: 2×35 V/5500 A IGBT DC power supply

Kulun Electric’s 2×35 V/5500 A IGBT DC power supply is applied in the stainless steel electroplating workshop of TISCO (Taiyuan Iron & Steel), China Baowu Steel Group, mainly providing stable, adjustable DC power for the stainless steel strip electroplating process. For plating line requirements of output stability, adjustment accuracy, process adaptability and continuous operation reliability, the supply uses modular IGBT high-frequency technology with flexible voltage/current adjustment, suiting metal surface treatment and continuous strip electroplating applications.

1. Project Overview

2. Application Background

Stainless steel strip electroplating is a continuous metal surface treatment process with high requirements on DC supply output stability, adjustment accuracy and operating reliability. During plating, supply output directly affects coating deposition rate, adhesion, uniformity and line continuity.

In the TISCO stainless steel electroplating workshop, the plating line requires the DC supply to adapt to long running hours, process parameter adjustment and site space constraints. Beyond high-current output, the supply needs strong CV/CC capability, protection functions and modular maintenance convenience.

3. Requirements & Technical Challenges

For this application, the heating and power control system had to address the following points:

• Adjustable output parameters: The plating process adjusts voltage and current by product, coating and line status, requiring flexible supply settings.
• High CV/CC capability requirement: Continuous plating needs stable output, minimizing supply fluctuation effects on coating quality.
• Complete protection functions: Industrial sites need input undervoltage, overvoltage, phase loss, output overcurrent and overheating protection.
• Limited installation and maintenance space: Plating workshops are densely equipped; the power system must be compact, lightweight and easy to maintain.
