Morgan Reducing and Sizing Mill

The Morgan Reducing and Sizing Mill is a high-performance rolling mill designed to produce high-quality steel wire rods by reducing and sizing them to precise dimensions. The key to success for markets around the world is to ensure highly productive and versatile wire rod mill operation. With a rich history of operational expertise and innovative engineering, the Morgan Reducing and Sizing Mill from Primetals Technologies is a highly advanced and sought-after wire rod sizing block technology, with nearly 90 installed strands worldwide

The Morgan Reducing and Sizing Mill offers a wide variety of benefits for wire rod producers: it can be integrated after a conventional finishing block, boosting mill productivity on small sizes by up to 60%. Its extreme precision and combination of advanced technologies lend themselves to thermomechanical rolling, which results in a more refined microstructure that can reduce or even eliminate costly downstream annealing processes.

The capacity to roll sizes from 4.0 mm up to 30.0 mm, combined with the capability for free-size rolling, ensures excellent size tolerance and ovality throughout the coil, from coil to coil and heat to heat. The Morgan Reducing and Sizing Mill can produce all rod sizes to ultra-precise tolerances as low as +/- 0.1 mm. The oval-round-round-round roll pass sequence delivers high-reduction rolling for normalized and thermomechanical processing, enhancing surface quality and extending roll life. The combination of pass design and multiple gear ratios in the external gear drive allows for multiple products to be produced from a single feed, greatly reducing product change times throughout the mill as well as minimizing roll inventory and roll shop costs.

High dimensional accuracy of rolled products is further enhanced by the Morgan Reducing and Sizing Mill's ability to achieve this at speeds of up to 120 m/s on 5.5 mm rod. This results in the highest production rates possible in the industry. The ultra-heavy-duty roll housings exceptionally handle high separating forces. With a capacity of more than 470 kN, the roll units can handle production of hard-to-roll alloys and thermomechanical rolling of carbon and low alloy steels, ensuring the ability to make products with better mechanical and metallurgical properties.

eDrive Technology: Revolutionizing the Morgan Reducing/Sizing Mill

The eDrive technology enhances the capabilities of the Morgan Reducing/Sizing Mill by combining cutting-edge electrical drives with the mill’s robust mechanical design. Individually driven stands provide infinite process flexibility, enabling mills to achieve optimized interstand tension-free rolling for improved grain structure and product quality. The system’s advanced roll housings support thermomechanical rolling, allowing for lower rolling temperatures down to 750°C, which reduces conversion costs and boosts product quality. Designed with efficiency in mind, the eDrive technology minimizes motor power requirements, lowers energy consumption, and reduces maintenance inventory through a commonality of components. The modular quick-change car arrangement ensures rapid size changes, enabling smaller rolling campaigns and maximizing mill utilization. This innovative solution empowers steel producers to expand their product range while achieving long-term cost savings and operational excellence.
