Siemens to modernize Wei Chih bar mill in Taiwan

  • In future, mill will be able to roll rounds with larger final diameters
  • Product portfolio widened to include flat and square bars
  • Optimized entry to cooling bed will improve surface quality

Bar handling system from Siemens

Wei Chih was founded in 1982 and produces concrete reinforcing steel and structural steels for both the domestic market and for export to a number of countries all around the world. High quality rounds were added to the product portfolio a few years ago.

Siemens supplied the bar mill in 1994, and a bar-in-coil mill in 2013. With cold charging the billets, it has an annual capacity of 450,000 metric tons, and produces rounds with diameters from 10 to 60 millimeters.

After completion of the modernization, the mill will be able to roll not only rounds with diameters up to 100 millimeters, but also flat bars with cross-sections ranging from 25x3 to 100x36 millimeters, and square bars with cross-sections ranging from 11.3 to 60 millimeters. The rolling mill processes carbon and quality steels.

Siemens will supply the process equipment for the modernization project and assist Wei Chih with the engineering of the items it will provide. The entry into the cooling bed will be equipped with braking slides that have special plating to substantially reduce the risk of scratching the surface of the newly rolled bars.

The cooling bed itself will be given a new rake system to handle the different geometries of the end products newly added to the range. An abrasive saw will be installed to cut the bars to length. Siemens will provide the bar bundling and handling machines with equipment designed to handle the new bar dimensions. Siemens will also supply the fluid systems and supervise assembly and commissioning work.

The Metals Technologies Business Unit, based in Linz, Austria, is one of the world's leading lifecycle partners for the metallurgical industry. The Business Unit offers a comprehensive portfolio of technologies, modernization solutions, products and services, as well as integrated automation and environmental solutions for complete plant lifecycles.
