Force detection in straightening CaRtaCCi’s fifty years of history have been marked by the production of straightening machines equipped with advanced technological solutions, able to meet the quality standards required by different market sectors. diameter; the absence of marks on the body or the ends of tubes; and complete surface coverage of the tube with consequent uniformity of the mechanical characteristics for each section of the tube.

machine is working on the tube in the process. This technology, called FDT (force detection technology) allows the display on the touchscreen of the applied efforts for each pair of rolls, on the tube in process, so that the operator has a greater awareness of the effects that the adopted setting may have on the product in qualitative terms. The technology is aimed at increasing both the quality of the product and the proficiency of the operator, who is provided with a means of having greater control of the process. FDT is based on the use of a sophisticated system that allows results to be achieved, maintaining the complete rigidity of the machine (the total absence of any mechanical play), which is fundamental to ensure the requested tolerances. The adoption of mechanical systems, such as loading cells, based on a minimum vertical movement, implies the loss of this characteristic. By using a hydraulic solution, FDT instead allows absolutely rigidity without compromising the principle working of the straightening machine.

In response to growing demand from customers operating in areas where quality standards are particularly high, Cartacci has developed a new technology that aims to provide the operator with a range of important information about the way in which the

The automotive and oil and gas industries in particular have determined an increasing adoption of ten-roll machines, able to control within close tolerances parameters including linearity on the body and at the ends of tubes; ovality around the nominal

Burners for annealing and galvanising lines to recover waste process gases INDUSTRIAL engineering group

pollutant emissions and improve energy efficiency. AdvanTek burners are a proprietary technology of Fives, designed for both reheating and processing line furnaces. The burners, equipped with combustion systems, operate with different fuel types, including coke oven gas, natural gas, mixed gas, LPG, heavy fuel oil and domestic fuel oil. The new AdvanTek WRT 2.0 burners use basic oxygen furnace (BOF) gas, which is a low heating value gas mainly composed of CO (LHV 7,100 kJ/Nm 3 ). A number of tests, conducted at Fives’

Bar-Le-Duc test centre in France, demonstrated an optimum combustion efficiency, with 71 per cent efficiency for BOF gas with NOx less than 50mg/Nm 3 at 3% O 2 . the combustion efficiency could reach 76 per cent with natural gas. AdvanTek WRT 2.0 burners are available for a power range of 100 to 180kW (7" and 8" W-shape radiant tubes), and can be installed in new or existing annealing and galvanising lines.

Fives has developed a wide range of AdvanTek ® WRT burners for annealing and galvanising lines to reduce
