HC 轧机改善了工作辊的受力状态,减少了工作辊的弯曲,使钢板平直。但支撑辊和工作辊端部有应力集中,严重者产生刻痕。为解决此问题,加强板形平直度的控制,西德西马克公司研制出了 CVC6-HS 轧机。这种轧机可使带钢卷全长的95％达到公称厚度±0.5％(厚度≤0.5mm)和1％(厚度≥6mm)。这种轧机的下、上中间辊磨成瓶形,通过其轴向移动而得到不同的辊缝形状,从而生产出平直的带钢产品。CVC6-HS 轧机是目前使冷轧带钢平直度达到理想状态的最佳机型,是控制手段最完备的机型。鞍钢应引进这种技术和机型。
HC mill to improve the work of the force state, reducing the bending of the work roll, so that the flat steel. But the support roller and the work roll end of the stress concentration, severe scoring. In order to solve this problem and strengthen the flatness control of the flatness, the West Germany company developed the CVC6-HS rolling mill. This type of rolling mill enables the nominal 95% of the strip to reach a nominal thickness of ± 0.5% (thickness ≤ 0.5 mm) and 1% (thickness ≥ 6 mm). The lower and upper rolls of this mill are bottle-shaped and produce different roll gap shapes by their axial movement, producing a flat strip product. CVC6-HS mill is the best model to make the flatness of cold rolled strip ideal and the most complete model of control. Anshan Iron and Steel should introduce this technology and models.
