为了最大限度取得密封OG的效果,保持炉口平滑干净,对经常的高密封性是重要的。附着金属由于蚀坑和放渣操作而增多,虽然使用金属溜槽也能去除附着金属,但为了减轻作业负荷,新日铁堺制铁所开发了利用炉体倾动转矩在短时间内除去炉口附着金属的装置。图1为炉口附着金属除去装置示意图。此装置设于炉前操作平台下,由金属除去刮刀和使刮刀在转炉炉口的倾动轨迹上滑动的机构以及油压驱动装置构成。本装置的去除力由转炉倾动转矩决定,设有过剩负荷限制
In order to maximize the effect of sealing OG, keep the furnace mouth smooth and clean, it is important for the regular high sealing. The attached metal is increased due to pitting and slag discharge operations. Although the use of a metal chute can also remove the adhering metal, in order to reduce the work load, Nippon Steel & Iron has developed a method using furnace tilting torque to remove the furnace mouth in a short time Metal-attached device. Figure 1 is a schematic view of the mouth attached metal removal device. The device is arranged under the front operating platform of the furnace and is composed of a metal removing scraper and a mechanism for sliding the scraper on the tilting trajectory of the converter mouth and a hydraulic driving device. The removal of this device is determined by the converter tilting torque, with excessive load limit
