Orbis+ Profile Measurement for Rod and Bar Rolling Mills

The Orbis+ is an advanced rotating profile measurement system for rod and bar rolling mills, which utilizes precision optics and advanced electronic processing to deliver complete 360° measurement of the product. In the dynamic and competitive world of steel production, maintaining critical dimensional accuracy to ensure consistent high product quality and reducing setup times to optimize production efficiency are paramount. The Orbis+ rotating gauge system offers a complete solution for rod and bar roughing and finishing mills, providing precise, real-time measurements to allow better operational control and improve yield.

The Orbis+ rotating gauge system for rod and bar rolling mills provides reliable, accurate measurement of rods and bars during the rolling process. This advanced system ensures that each product is comprehensively measured to meet the most stringent quality standards, thereby reducing waste and improving overall production efficiency. The Orbis+ is designed to continuously and accurately measure the full profile of rounds, flats, rebar, square, octagonal, and hexagonal sections, regardless of the orientation and movement of the product within the gauge. The Orbis+ rotating gauge system delivers exceptional performance and reliability. Its robust construction and proven technology ensure precise measurements in even the most demanding environments, and it is equipped with both air-purging and water-cooling systems to safeguard it from dust and high temperatures.

The optical system of the gauge rotates around the bar, scanning the entire profile. Using an LED light source and a high-resolution digital camera, the gauge makes 2,000 measurements per second around the full 360° profile of the product. The Orbis+ system provides continuous, real-time product data that is transmitted from the gauge head to the operator workstation, where it is displayed on a user-configurable screen in both numerical and graphical forms. The graphical display includes both a linear trace and a polar plot, highlighting bar defects such as overfill, underfill, and roll cross, enabling quick identification of potential problems in the rolling process. If an optical pyrometer is provided, the bar temperature can also be measured and used to convert the product dimensions obtained in the hot state into final product dimensions at ambient temperature. The information can also be sent to optional large-screen displays in the mill environment, next to the line, allowing plant personnel to easily monitor and adjust the process quickly to maintain optimum performance and quality.

The Orbis+ system's user-friendly interface and software make it accessible to all levels of personnel. The data storage options allow retrieval and display of historical data to help diagnose issues quickly and easily. To provide safe and efficient maintenance of the gauge, it can be mounted on a trolley to allow easy withdrawal from the production line. In summary, the Orbis+ profile measurement system for rod and bar rolling mills from Primetals Technologies provides reliable, precise real-time measurements of the full product profile, enabling mill operators to produce consistent high-quality products, increase yield, reduce downtime, and meet or exceed the demands of a competitive steel market.

Benefits of Orbis+ Profile Measurement for Rod and Bar Rolling Mills

• Early detection of defects and size changes, resulting in reduced scrap and increased yield
• Early indication of roll wear allowing scheduled roll changes and maintenance
• Improved product quality, maintaining close dimensional tolerances
• Reduced manual inspection and sampling
• Avoidance of out-of-tolerance products delivers a reduction in further processing and therefore lower energy consumption and improved mill productivity.
