Import Electro Slag Remelting Crystallizer Crucible — Buy in wholesale FOB from Supplier in China

The Electro Slag Remelting Crystallizer Crucible from Dalian Dashan Metallurgical Engineering Technology Co., Ltd. is manufactured using either seamless forged copper pipe or rolled and welded copper sheet, with material options limited to CuCrZr or oxygen-free copper. The CuCrZr variant contains chromium between 0.5% and 1.5%, zirconium between 0.08% and 0.30%, with copper making up the balance. Mechanical properties include a tensile strength of at least 350 MPa, electrical conductivity of at least 80% IACS, a hardness of at least 100 HB, and elongation of at least 20%. These values are measured under standard testing conditions and reflect the material’s performance under high thermal stress.

The crucible is produced using cold welding and hot/cold forging techniques that refine grain structure and enhance structural integrity. This results in a product with higher strength and resistance to deformation at elevated temperatures compared to conventional copper alloys. Typical industry alternatives include pure copper or copper-nickel alloys, but CuCrZr is preferred in electroslag remelting for its superior softening resistance above 400°C. The absence of seams in forged versions reduces risk of leakage under pressure, while welded flange designs are standard for modular assembly in continuous casting lines.

These crucibles are primarily used in steel and specialty alloy production facilities that employ electroslag remelting to purify ingots. Buyers include metallurgical plants in Southeast Asia, Eastern Europe, and the Middle East that require consistent thermal stability and minimal contamination. Packaging is typically wooden crates with internal foam padding. Trade terms are generally FOB Dalian or CIF, with lead times of 4 to 6 weeks depending on order volume. Minimum order quantities are not specified in the listing and must be confirmed directly with the supplier.

Dalian Dashan Metallurgical Engineering Technology Co., Ltd. is based in the Hi-Tech Zone of Dalian, Liaoning, China. The company specializes in the design and production of crucibles and components for electroslag remelting systems. Its listing indicates a harbor trust tier, suggesting verified shipping and export capacity, but no public information confirms production volume, employee count, or client names. The absence of response rate and average response time signals that communication may require direct inquiry.

The company does not claim ISO certification, years in operation, or export history in its profile. Its technical documentation focuses exclusively on material composition and manufacturing processes, indicating a product-driven rather than marketing-driven approach. No claims are made regarding certifications, awards, or partnerships. Buyers should treat this as a manufacturer with documented engineering capability but unverified commercial scale.
