摘　　要：立辊轧机主要用于限制板坯宽展和控制板坯宽度精度。采用特殊合金铸钢制作的热轧生产线E4立辊在使用中磨损严重,为此,研制了一种耐磨性很好的高铬铸钢E4热轧立辊,有效减小了立辊的局部磨损,延长了立辊的使用寿命,取得了良好的经济效益。Vertical mill was mainly employed in restriction on slab spread and control of precision of slab width.E4 edger roll made of a special alloy cast steel for a hot-rolling production line was severely worn.For this reason an E4 hot-rolling edger roll made of high-chromium cast steel having excellent wear resistance was developed,appreciably reducing amount of local wear of the edger roll,prolonging its service life,thus obtaining good economical gain.
