摘要
以唐钢热轧1700线扇形段S7-9的防腐修复为例,采用不锈钢水道替代普碳钢水道、等离子堆焊方法在扇形段轴承座上面,以及与其配合的水孔内堆焊防腐蚀材料,提高轴承座与辊子的密封效果,改善了扇形段的使用性能,延长使用寿命。
The anti- corrosion repair of segment S7 to S9 of 1700 hot rolling line is stated： using stainless steel water channel to substitute normal carbon steel one, build - up welding anti - corrosion material with ion welding on bearing block of segment and in the matched water hole. With these measures, the seaming be tween roll and bearing block is improved, the use property of segment improved, its work life prolonged.
