万能成品轧机轧制腿内侧为双斜度的重轨时,在两直线交接处出现氧化铁皮粘结现象,严重影响产品质量和产量。按传统思路从工艺进行了多次优化仍无法消除或减轻。后采取MARC软件对UF孔型中的金属流动规律进行仿真分析,找到了工艺优化无法解决粘结的原因。借鉴润滑轧制的原理,从轧辊材质的优化试验中使氧化铁皮的粘结得到了大幅度减轻。一套新材质轧辊比原轧辊在相同使用周期内提高产量达176.5 t。
When the inside of the finished product rolling mill has a double-slope heavy rail, sticking of the scale on the two straight lines occurs, which seriously affects the product quality and output. According to the traditional ideas from the process of optimization many times still can not eliminate or reduce. MARC software was adopted to simulate the metal flow in the UF pass, and the reason why process optimization could not solve the problem of bonding was found. Draw lessons from the principle of lubrication rolling, from the roll material optimization test so that the oxide scale bonding has been greatly reduced. A set of new material roll than the original roll in the same life cycle to increase production of 176.5 t.
