BAR MILL — Solutions to ensure high durability and maximum availability 凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

Systems and components are designed for high durability and maximum operation uptime, to meet the specific requirements of productivity, tolerance, surface finish and metallurgical quality. 凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

Red Ring rolling stands are suitable for use in a wide range of situations. Multi-slit and high-speed technologies ensure that the requirements of high productivity of rebars are safely and efficiently guaranteed. Through bar-in-coil operation by V+ coilers, compact and twist free coils of bars and convex shapes are produced. State-of-the-art cooling technologies are available, for controlling the distortion of merchant bars, for thermo-mechanical rolling and for quenching & tempering both carbon and alloy grades, including stainless. The 2+4 EVO reducing and sizing mill further improves the dimensional accuracy of SBQ bars with a better control of metallurgical structure.



Primetals Technologies has installed or upgraded more than 1,000 rolling mills on six continents. These mills have set worldwide benchmarks for technological leadership, reliability and performance.

Red Ring Series 5凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

The Red Ring housingless stand design has a high reputation for roughing, intermediate and finishing applications. With more than 7,000 units commissioned worldwide, its design is renowned for its fully automatic operation, high rigidity and ease of maintenance. With an improved resistance to wear of key components, the Series 5 stands are available in different sizes and configurations.

Roughing Solutions for Billets, Blooms and Large Rounds凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

The roughing area plays an important role in the flexibility of production of a modern mill, the reduction of its layout space, the minimization of the costs of rolling and post-rolling operation. All with automatic operation and maintenance procedures, several applications are available:

  • Forging-like rolling, it offers a cost-effective alternative to the ingot-casting route for large dimensions
  • Compact rougher, for high reductions in a limited space
  • Reversing 2-high stand rougher, in horizontal-vertical with highly flexible process
  • Sliding stand rougher, it simplifies the manipulating system and associated civil works

Compact Cassette Rolling Stands (CCR)凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

The CCR stands suit the demanding requirements of special bar rolling. The extremely rapid cassette change facility, allows for flexible and efficient production, even for orders with a small number of billets. Available with monogrooved or multigrooved stands and also as a reversing block, CCR stands offer an easy access from the top and can be arranged in horizontal, vertical and 45° configurations. Its compact design reduces the building height requirements.

2+4 EVO Bar Reducing and Sizing Mill凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

The 2+4 EVO reducing and sizing mill uses a patented pass design. A reducing group with 2-Roll stands with high reduction is followed by a sizing group with 4-Roll stands with low reduction. While the 2-Roll high reduction guarantees the desired metallurgical structure, the 4-Roll low reduction provides excellent surface finish and size tolerance. The 2+4 EVO effectively employs the concepts of single-family and free-size rolling, which both reduce the required number of roll sets. The utilization and productivity of the mill are greatly improved.

Inline Cooling Technologies凤凰彩票平台手机版,凤凰彩票开奖APP,凤凰彩票开奖下载

In a modern mill the mechanical deformation actions are completed by inline controlled cooling technologies in order to obtain important benefits, like an improved process control, the reduction of product non-conformities and lower operation costs. From rebar quenching to thermo-mechanical rolling for quality bars and to inline solubilization of stainless grades, several solutions are available, all with automatic operation and assisted by validated thermo-metallurgical models.
