Precision measurement 3

The new Laser Series 6000 diameter gauges ▲ ▲

In this position it is protected against water, dirt or mechanical influences during production. A special feature, carried over from the larger Laser Series 2000 gauges, is the swivel gauge head design. It allows for the gauge head to be easily moved up, out of the extrusion line. The measuring axes are arranged in such a way that the gauge is open at the bottom to prevent dirt and water from falling into the measuring area. Sikora offers the Laser 6020 XY for product diameters from 0.25mm to 20mm, Laser 6040 XY for a measuring range from 0.5mm to 40mm and the Laser 6080 XY for products from 1mm to 80mm.

New laser devices will expand Sikora’s current range of diameter gauges by three powerful models, said to offer even higher precision and reliability and so improving the efficiency of the production line. The 2,500 measurements per second provide extremely high single-value pre- cision, ensure an optimum line control and provide reliable statistical data. With the new devices the cable diameter is measured with an accuracy of up to 0.2 micrometres. Sikora engineers are said to have integrated a number of practical improvements. The opening of the gauges is twice as large as the measuring range, to ensure an easy cable feed through. Directly integrated into the gauge head is a new, pluggable universal interface module for all connections.

New bar mill for Handan Iron

Handan Iron & Steel Co plans to increase its production capacity and widen its range of products with a new long-product rolling mill in Handan. The bar mill will produce 800,000 tonnes of special bar quality (SBQ) steels per year. Siemens is supplying mechanical equipment including a six-stand roughing mill, an eight-stand intermediate mill and a six-stand pre-finishing mill. A three-stand sizing mill completes the bar mill. The scope of supply also includes parts of the cooling system, pinch rolls, a convertible dividing shear, a fixed cold shear with a cutting force of 1,200 tonnes, guides, equipment for the oil-air lubrication system as well as spare parts, including 15 rolling stands. The wire rod mill will have a roughing and an intermediate mill and a four-stand pre-finishing mill, including guides and oil-air lubrication systems. These plant components will complement the rod outlet that Handan Iron & Steel had previously ordered from Siemens. When complete, the wire rod mill will process about 700,000 tonnes a year of standard carbon and alloy steels as well as bearing and spring steels. Handan Iron & Steel Co, part of the Hebei Iron & Steel Group Co Ltd, is among China’s leading steelmakers and produced over 33 million tonnes of steel in 2008.
