Steel tundish price

The price of a steel tundish is primarily driven by its capacity (tonnage), refractory lining material, and flow control technology. Buyers should specify the steel grade being cast, as high-oxygen or corrosive steels require magnesia-based or alumina-magnesia linings which are more expensive but offer higher durability. Additionally, the inclusion of flow control devices like dams, weirs, or turbulence inhibitors significantly affects the price but is essential for improving steel cleanliness and reducing inclusions.

While silica-based linings have a lower initial cost, they have shorter service lives. For continuous casting, investing in high-quality basic refractories (MgO) or zirconia inserts for the nozzle area is more cost-effective in the long run. These materials provide superior thermal shock resistance and chemical stability, leading to fewer shutdowns and a lower cost-per-ton of steel produced.

Suppliers must adhere to ISO 9001:2015 for quality management and ISO 14001 for environmental standards. For the structural steel shell, ensure compliance with ASTM or EN standards regarding welding integrity and heat resistance. It is critical to request refractory pressure testing reports and thermal expansion analysis to prevent breakouts during the casting process, ensuring operational safety in the melt shop.

Yes, most professional suppliers on Made-in-China.com offer OEM/ODM services. Buyers should provide CAD drawings or specific CCM (Continuous Casting Machine) parameters. Customizations often include the number of strands (outlets), the tundish shape (T-type, V-type, or rectangular), and the integration of induction heating systems to maintain precise molten steel temperatures.

The main risks include logistical damage and specification mismatch. Due to the extreme weight and size, ensure the supplier uses seaworthy packaging with reinforced steel bracing. To mitigate technical risks, utilize third-party inspections (such as SGS or BV) before the final balance payment to verify dimensional accuracy and refractory coating thickness.

Negotiate based on Total Cost of Ownership (TCO) rather than just the unit price. Request a bundled discount if purchasing the steel shell along with a year's supply of refractory nozzles, stoppers, and well blocks. Suppliers are often willing to reduce the shell price by 10-15% if a long-term consumable supply contract is established.

Given the weight, Ocean Freight is the only viable option. FOB (Free On Board) or CIF (Cost, Insurance, and Freight) are standard. However, for large tundish shells, Breakbulk shipping may be required if they do not fit in standard containers. Ensure the contract specifies Heavy-Lift handling fees and clear responsibility for marine insurance to cover potential transit accidents.

Always use secured payment terms such as Letter of Credit (L/C) for large-scale orders or Escrow services provided by reputable platforms like Made-in-China.com. Avoid 100% upfront payments; a standard structure is 30% deposit and 70% against the Bill of Lading (B/L) after successful pre-shipment inspection.
