中文摘要 | 鋼帶壓痕在第二連續退火線出料端常造成剔退,尤其第二連續退火線產線特性為連續性且速度快。當輥面發生附著物時會轉印至鋼帶上,造成品質的缺陷而遭到大量剔退。現場操作人員為了減少大量剔退發生,必須處理輥面附著物,往往因產線不能停、時間緊迫且又無高效率的清除工具,經常是事倍功半,而且人員也有被鋼帶捲入之危險。 基於這些構想,所以引進日本三井公司之Doctor Blade,裝設於最易發生輥面附著物的四支輥子上。試用後相關缺陷量已明顯減少,每月約可減少壓痕剔退量40~50噸左右,效益顯著。 |
英文摘要 | Dent defects on strip are often causing coil rejected in No.2 Continuous Annealing Line (No.2 CAL) delivery section. Especially for continuous and high speed CAL line, if deposits on rolls and strip marks are happened, it causes coil rejected and high tonnage losses. To decrease the tonnage losses, if roll deposit is happened, operator should reach job site to inspect and remove deposits from the roll surface as soon as possible. Such work is even difficult and dangerous due to the line is still running and lack of efficient removing tools. Furthermore, the operator might be in danger of being pulled into the roll-bite. Due to the above reason, the Doctor Blades are installed on four-(4) roll, which deposits are most often occurred. After trial running, the dent defect tonnage is decreased sharply, it is about 40~50 tonnage gained as per statistics. |
