Fast changeover and reduced downtime with advanced tube mill range

Infrared thermometer for rolling-mill processes

Sitel Control Srl, Italy, is a specialist in the design and manufacture of infrared optical pyrometers for the control and supervision of industrial processes. Certified according to UNI EN ISO 9001:2000, the company provides the industry with optical thermometers produced with the most update-to-date microprocessor technologies. A highlight of the company’s range is the Starline model of infrared thermometric system, which enables a complete temperature profile with a single instrument.

Abbey International, USA, is the manufacturer of a wide range of tube mills, with a size range from Ø 3-26″. The company is currently undertaking a number of international projects for industries including oil and gas, automotive, and construction. The company has recently carried out delivery of a high-speed 3″ mill line. The line is capable of producing rounds, rectangles and squares at 600ft/min. This project includes the company’s patented CCT quick-change system. The Continuous Cart Transfer (CCT) is a driven cart system designed to receive sub-plated mill sections during semi-automated changeover of the mill. It eliminates the use of an overhead crane for sub-base exchange. With the CCT system, very fast changeover times are possible, thus substantially reducing mill downtime. The payback on this system is extremely quick especially when frequent tool changes are required. Abbey has also received two orders for special automotive mills for producing stainless steel tubing. The first is for a 3.5″ mill line that will be delivered in the next few months, with the second a 6″ mill line set for installation later this year. Both of these orders incorporate Abbey’s Transition Beam Forming Section (TBS ® ), a patented system that provides an expanded  Abbey’s 3 ″ mill line with CCT quick-change system

capability of forming, creating high quality pipe over a wide range of sizes. The 3.5″ mill line will also feature a special compression forming system. The company will also deliver a special coil tubing mill for use in the oil industry. The coil tubing mill will produce high strength tubing for oil wells. With this mill, Abbey International has incorporated numerous special features for making precision coil tubing and linepipe for API. Abbey will also provide a heavy wall 5″ mill line for the structural industry, which incorporates high speed and quick-change capabilities. This mill line is able to produce rounds, squares, and rectangles at 400ft/ min. Another order won by the company is a heavy 5″ mill for the oil industry. Abbey International’s largest project is a 26″ mill line for structural columns and line pipe for API. Claimed to be one of the most advanced large ERW tube mills available, this mill line is capable of producing squares of 550mm x 550mm. It was designed to operate with a reduced crew using high- level automation. It also incorporates advanced quick tooling change features including the TBS forming and cassette roll change systems.

 The Starline excels in monitoring temperatures on rolling mills

The system features powerful software functions that provide a complete thermal map or peak temperature measurement on a moving target by means of data coming from the 32 elements sensor array. The temperature range extends from 550°C to 1,800°C, with a correction capability where there is a change in material emissivity. Starline’s design has been engineered to avoid problems due to vibration, friction and ageing. As with all Sitel’s instruments, the Starline has a solid design and compact protective case that ensures optimum accuracy and reliability. The anticorodal aluminium case includes a cooling and air-purge system, enabling the instrument to be installed in very hot and dusty hostile industrial environments. The microprocessor-based electronic provides both digital and analogue outputs for connections to any type of control system. Starline can also be connected to a common PC, where a Windows ® -based software can be installed for a real-time profile measurement, data recording and thermal map visualization.
