Copper mould plates (also known as copper moulds or crystallizer plates) and chromium zirconium copper plates (CuCrZr alloy plates) are essential consumables in continuous casting machines (CCM) for steel production. They enable rapid heat extraction from molten steel to form solidified shells, requiring high thermal conductivity, wear resistance, strength at elevated temperatures, and excellent machinability. Chromium zirconium copper (CuCrZr, C18150) is the most common high-performance alloy for these applications due to its superior combination of conductivity (~80-85% IACS) and mechanical strength.
China dominates global production of these components, supplying over 70-80% of the world’s continuous casting mould needs, driven by massive steel output and advanced alloy processing capabilities.
Below is a curated ranking of leading manufacturers in China for copper mould plates and chromium zirconium copper plates (based on production scale, market share estimates, technological expertise, export volume, patents, and references from industry reports, steel mill suppliers, and platforms like Made-in-China/Alibaba in 2025-2026). Note: Rankings are approximate/reference-based, as exact market share data is often proprietary. Longcheng is widely recognized as the domestic leader.
