Electric arc furnace 10 ton

When sourcing a 10-ton EAF, prioritize the Transformer Capacity, which typically ranges from 6,000 to 8,000 kVA for this size to ensure efficient melting rates. Evaluate the Electrode Regulation System; modern furnaces should utilize PLC-based hydraulic or digital electrode control to minimize energy consumption and electrode breakage. Additionally, verify the Shell Diameter and Refractory Lining thickness to ensure thermal efficiency and structural integrity during high-temperature operations exceeding 1,600°C.

The equipment must adhere to international safety and quality benchmarks. Ensure the supplier provides ISO 9001 certification for manufacturing quality. For electrical safety and pressure components, look for CE Marking (EU) or ASME certification for hydraulic systems. Crucially, the furnace must comply with Environmental Protection Standards regarding dust collection and gas emissions, requiring integrated Fume Extraction Systems (Primary and Secondary) to meet local air quality regulations.

Request data on the Specific Energy Consumption (SEC), which should ideally be between 350 and 450 kWh/t for modern units. Inquire about the inclusion of Oxy-fuel Burners and Carbon Injection Systems, as these technologies can significantly reduce tap-to-tap time and electricity usage. Furthermore, evaluate the Water-Cooling System efficiency for the roof and panels, as effective cooling extends the lifespan of consumables and reduces downtime for maintenance.

A 10-ton EAF is ideal for Mini-Mills, specialized alloy steel foundries, and scrap metal recycling plants. It is highly versatile, capable of processing heavy melting scrap (HMS), shredded scrap, and Pig Iron. If your production involves high-purity alloys, ensure the furnace supports Slag Foaming and has a reliable Bottom Tapping (EBT) mechanism to ensure slag-free tapping and higher yield quality.

The most significant risks include Technical Mismatch and Shipping Damage. To mitigate these, use Made-in-China.com's Secured Trading services to ensure payment is only released upon verification. Conduct a Pre-Shipment Inspection (PSI) by a third party (like SGS or Intertek) to verify that the mechanical and electrical components match the agreed-upon technical drawings. Ensure the contract specifies Seaworthy Packaging, including anti-rust coating and vacuum sealing for sensitive electronic control panels.

Since an EAF requires complex assembly, negotiate a Turnkey Solution or Supervised Installation. The contract should explicitly state the Engineer's Daily Rate, travel expenses, and the duration of on-site training for your local operators. Demand a Spare Parts Package (electrodes, water-cooled cables, and sensors) to be included in the initial shipment to prevent operational delays during the first year of use.

Due to the weight and dimensions, this equipment often requires Flat Rack or Breakbulk shipping rather than standard containers. Confirm the Incoterms 2020; CIF (Cost, Insurance, and Freight) is often preferred for heavy machinery to ensure the seller handles the complex loading and insurance. Additionally, check your country's Import Tariffs on Steel-Making Machinery and verify if there are any anti-dumping duties or energy-efficiency subsidies that apply to your purchase.

Always utilize Letter of Credit (L/C) or Escrow payment methods provided by reputable platforms like Made-in-China.com. Avoid direct wire transfers to unverified accounts. Implement a Milestone Payment Schedule: for example, 30% as a down payment, 40% after successful factory testing, 20% upon arrival at the port, and the final 10% after the Performance Guarantee Test (PGT) is passed at your facility.
