德国KOCKS公司的三辊精密定径机组首次安装在美国乔治敦钢铁公司的双线线材轧机的精轧机组之前,以消除进精轧机组坯料的尺寸波动。它使成品线材的尺寸精度由±0.25mm提高到±0.05～0.1mm;并可消除端头增粗,使切头尾量由2～10圈减少到0.5～2圈,提高成材率0.5％以上。其产品原最小至Φ5.5mm,现可生产Φ5.0mm线材。
The three-roll precision sizing unit from KOCKS GmbH, Germany, was installed for the first time at the finishing mill of a two-wire wire rod mill at Georgetown Steel in the United States to eliminate dimensional fluctuations in the billet of the finishing mill. It makes the dimensional accuracy of the finished wire from ± 0.25mm to ± 0.05 ~ 0.1mm; and can eliminate the end thickening, cut the tail from 2 to 10 laps reduced to 0.5 ~ 2 laps, improve the yield of more than 0.5% . The original product to the smallest Φ5.5mm, can produce Φ5.0 mm wire.
