Treatment method for reducing molten iron erosion

The invention provides a treatment method for reducing molten iron erosion, and relates to the technical field of blast furnace slag iron treatment. The double sand dams are arranged on the blast furnace, so that the damaged sand dam can be replaced without damping down; by increasing the filtering interval for slag to pass through the skimmer, adjusting the channel height of the skimmer, reducing the bottom layer height of the skimmer during pouring, increasing the fall between the front part and the rear part of the main runner and reducing the height of the iron storage liquid level of the main runner, the molten iron can safely and smoothly pass through the skimmer, the molten iron recharge is eliminated, and the serious erosion phenomenon is reduced; and the potential safety hazard of iron notch burning is avoided. 本发明提出一种降低铁水侵蚀的处理方法，涉及高炉渣铁处理技术领域，本发明根据实际情况，对撇渣器进行升级改造；在高炉上设置双砂坝，不休风情况下能够更换损坏的砂坝；增加炉渣通过撇渣器的过滤区间，通过调整撇渣器的通道高度，浇筑时降低撇渣器的底层高度，增加主沟前后的落差，降低主沟贮铁液面高度，保障铁水能够安全、顺利的通过撇渣器，消除了铁水回灌降低了侵蚀严重的现象，避免烧坏铁口的安全隐患。
