Chinese steel producer: 6-strand bloom casting machine from Primetals

by David Fleschen

A steel manufacturer based in northeastern China has placed an order with Primetals Technologies for a new 6-strand bloom casting machine. The equipment is scheduled for implementation in 2025, with the aim of enhancing production efficiency and quality.

High-Quality Bloom Production

Primetals Technologies will provide the complete mechanical equipment, along with Level 1 and Level 2 automation systems. The decision to collaborate with Primetals Technologies was influenced by the company's extensive experience with long casting machines and a strong portfolio of similar projects.

The new caster will be used to manufacture high-quality blooms for export markets, including premium rails and wire rods, such as steel cord for tire reinforcement. The machine will feature the largest curved copper tube mold developed by Primetals Technologies, supporting cost-effective production of thick, high-value-added blooms. Additionally, the DynaFlex hydraulic oscillator will allow for flexible mold-oscillation parameter adjustments, contributing to improved strand surface quality.

Advanced Automation Systems

The casting machine will incorporate state-of-the-art automation solutions to optimize production. The fully automated roll-gap control system, DynaGap Soft Reduction, is designed to minimize centerline segregation, improving internal strand quality. The system will also include Dynacs 3D, a secondary cooling model that generates a complete 3D temperature profile along the strand, allowing for precise adjustments to secondary cooling setpoints. Mold level stability will be managed by the automatic LevCon control system, featuring autostart casting functions and auto-adaptive dynamic bulging compensation.

Part of a Multinational Enterprise

The steel producer operates as part of a multinational enterprise group, manufacturing a diverse range of products, including rebar, plate, hot-rolled sheet, cold-rolled sheet, galvanized sheet, color-coated sheet, round steel, profiled steel, wire rod, and steel rails. The addition of the new bloom caster aligns with the company's commitment to expanding its production capabilities and supplying high-quality steel products to international markets.
