Multipurpose crane for graphite electrode assembling and handling

Weihua’s multipurpose crane for graphite electrode assembling and handling is a world-first intelligent equipment developed by Weihua Group’s Technology Center through targeted R&D aimed at solving specific process pain points in the carbon industry. It fundamentally transforms the original, inefficient manual handling模式 long relied upon in graphite electrode production by integrating the two core processes of “assembling” and “handling,” achieving a revolutionary upgrade of the production workflow.

During the manufacturing process of graphite electrodes, they undergo multiple complex steps such as stringing, wrapping, transfer, and furnace loading/unloading. Traditional methods heavily rely on manual labor, which presents numerous drawbacks including low efficiency, harsh operating environments (“dirty, tiring,笨拙”), susceptibility to product damage, and significant safety hazards. This product was specifically developed to address these issues. It enables a fully automated process from assembling to handling in key stages such as the graphitization treatment of graphite electrodes, truly achieving “multi-functionality in one machine” and greatly enhancing the intelligence level of the production line and product quality.

Structural Composition

The multipurpose crane for graphite electrode assembling and handling is a complex mechatronic system integrating advanced mechanical structures, hydraulic systems, and intelligent control. Its core composition can be summarized into two main functional modules: the intelligent assembling system and the multipurpose lifting and handling system.

• Intelligent Assembling System
  • Main and Auxiliary Hydraulic Propulsion Devices: Provide precise and stable propulsion power for the assembling platform, ensuring neat electrode arrangement.
  • Mobile Wrapping Device: Automatically完成 the wrapping of assembled graphite electrodes with stretch film, replacing manual labor.
  • Automatic Spacer Placing Device: Enables automatic and precise placement of graphite spacers, preparing for the assembling process.
  • Damping Roller Device: Ensures smooth movement of single or grouped electrodes during assembling, preventing collision damage.
  • Assembling Platform: The core worktable, capable of automatic single-row or double-row electrode assembling and flexible切换.
• Multipurpose Lifting and Handling System
  • Specialized Composite Spreader: A core innovative component. It integrates multiple types of clamps, enabling stable gripping of single-row or double-row graphite electrodes of various specifications, and is also equipped with a dedicated furnace cover lifting hook, achieving “multiple functions in one spreader”.
  • High-Precision Hoisting and Travel Mechanism: Utilizes advanced drive and control technologies (such as Weihua’s high-speed, high-precision distributed control system) to ensure smooth lifting operations and precise positioning.
  • Intelligent Control System: Equipped with a “most powerful brain” like the ASW-2100C central controller,它 quickly responds to commands, coordinates all movements, and can be connected to a remote operation and maintenance platform for intelligent management.

Advantages & Features

Applications

The multipurpose crane for graphite electrode assembling and handling is a specialized intelligent manufacturing equipment whose application is highly focused on specific industrial chain segments:

• Core Application Industries: Carbon Industry & Metallurgical Industry
  • Carbon Product Manufacturing Industry: Specifically used in production lines for ultra-high power graphite electrodes, particularly for the assembling, transfer, and furnace loading/unloading processes before and after baking and graphitization treatment.
  • Upstream Metallurgical Industry (Electric Arc Furnace Steelmaking): Although not directly used at the steelmaking site, the product it manufactures (graphite electrodes) is a key consumable raw material for electric arc furnace steelmaking. This equipment indirectly serves the steel smelting field by improving the production efficiency and quality of electrodes.
• Specific Application Scenarios:
  • Ultra-high power graphite electrode projects with a scale of 100,000 tons or more.
  • Carbon material production bases with an urgent need for production automation and intelligent upgrades.
  • Advanced manufacturing projects aimed at building “dark factories” and achieving unmanned production lines.
