镀锌机组高铝气刀抽吸装置自动控制技术改进

Improvement to Automation of High-Aluminium Main Nozzle of Aspirator in Continuous Galvanizing Line

气刀是镀锌机组重要的在线设备,气刀控制精度直接影响镀锌板的质量,特别是对高铝锌产品影响更大。镀锌机组高铝气刀抽气装置自动控制技术的改进,成功地解决了镀锌板边厚这个难题,有效地改善了酒钢镀锌产品的质量。

Aspirator is the important equipment in continuous galvanizing line （ CGL）, it has great impact on coating surface, especially on the thickness of strip edge. Usually, the aspirator cant work in auto mode, which causes damage on equip- ment and leads to the over-thickness of strip edge. The development of aspirator automatic control has solved the problems successfully and promoted surface quality of coils coating in JISCO.
