中文摘要 | 中鋼公司第二連續退火線後段所裝設的四重式調質軋延機,除了可以改善產品鋼帶機械性質與表面粗糙度外,若操作員謹慎調整操作軋延機,還可用以改善鋼帶平坦度;若是板形變化太快而人員無法即時反應,或是經驗不足,或是操作不慎,則可能使其平坦度惡化而產生品質缺陷。為了改善人為調整操作所可能產生的缺陷,陸續實施了操作與程控的改善,最後則安裝了平坦度計,導入可以做自動板形控制的平坦度控制系統,改善鋼帶平坦度,減少鋼帶邊波及邊緣應變痕的缺陷。本文主要介紹平坦度計的架構、應用以及問題點改善。 |
英文摘要 | There is a four-high temper mill in the delivery section of China Steel No.2 continuous annealing line (CAL). The function of a temper mill is to stabilize and alter the metallurgical properties of the strip, to provide a final surface texture and to improve the shape of the strip. However, an operator should be very cautious to operate and adjust the mill to get a good strip shape. In order to improve the reliability of strip shape control and to reduce the defects of strip edge wave and stretcher strain, a shapemeter for flatness measurement and automatic flatness control was installed recently. This article introduces the architecture and application of a shapemeter and how it was improved during commissioning and test running. |
