近年来,切分轧制新工艺发展很快,被公认为是未来轧钢工业发展方向,是轧钢领域开拓性技术。当今世界上仅有苏、日、加、美等国掌握此项技术,并具有专利权。切分轧制就其产品不同,大致可分为钢坯切分(包括板坯切分)和型材切分两大类。我们在ф250×2轧机上做的工业性试验属于前者。钢坯切分轧制具有吨钢能耗低,金属切损少和产量高等优点。它的最大特点就在于,在不改变现 In recent years, cutting new technology developed rapidly, is recognized as the future direction of the rolling industry, rolling steel is pioneering technology. Today, only the Soviet Union, Japan, Canada and the United States have mastered this technology and have the patent right. Slicing and rolling their products, can be divided into billet cutting (including slab cutting) and profile cutting two categories. The industrial test we made on the ф250 × 2 mill belongs to the former. Billet cutting and rolling has the advantages of low energy consumption per ton of steel, less metal cutting and high output. Its most important feature is that, without changing the present
