摘要： A method of operating a rolling mill in a manner that avoids the occurrence of alligatoring in a slab of metal as it is reduced in thickness in the mill. The slab is subject to a schedule of repeated passes through the mill to effect a predetermined amount of reduction in thickness of the slab in each pass. The method comprises the steps of analyzing the pass schedule of such a slab, and noting any pass in the schedule that has a combination of entry gauge and reduction draft that may subject the slab to alligatoring. An untapered nose of the slab is next presented to the bite of the mill, and if the combination of entry gauge and reduction draft is one that is not subject to alligatoring, the slab is passed through the mill to reduce its thickness as scheduled. However, if the combination of entry gauge and reduction draft is one that causes or tends to cause alligatoring in the slab, the method changes the size of the working gap of the mill by an amount that changes the combination of entry gauge and reduction draft to one that does not subject the slab to alligatoring. The nose of the slab is then directed to the bite of the mill having the changed working gap, and, once the nose of the slab has entered the bite of the mill, the working gap thereof is returned to the size that will effect the schedule reduction and thickness of the slab.

摘要： A method of reducing the thickness of a slab of metal under conditions that tend to produce alligator defects in the ends of the slab, the method comprising the steps of tapering at least one end of the slab and directing the same into a rolling mill. The tapered end of the slab is reduced in thickness in the mill, the amount of reduction increasing as the tapered end passes through the mill. The slab continues through the mill to reduce the thickness of the same. The end of the slab is again tapered and directed again through a rolling mill, with each of said tapers providing combinations of entry thickness to thickness reduction such that the reduction taken in the area of each taper is in an entry thickness to thickness reduction zone that does not produce alligatoring in the ends of the slab. The remaining untapered portion of the slab is reduced in thickness in the mill in an entry thickness to thickness reduction zone in which alligator formation tends to occur.
摘要翻译：一种在倾向于在板坯的端部产生鳄鱼皮缺陷的条件下减小金属板块的厚度的方法，该方法包括使板坯的至少一端锥形并将其引导到轧机中的步骤。板坯的锥形端部在轧机中的厚度减小，随着锥形端部通过轧机，轧制量的减少量增加。板坯继续穿过轧机以减小其厚度。板坯的端部再次是锥形的并且再次通过轧机，其中每个所述锥体提供入口厚度与厚度减小的组合，使得在每个锥形区域中的减少是进入厚度到厚度减小区域，在板坯的末端不产生鳄鱼皮。板坯的剩余未加工部分在轧机中的厚度减小，其中倾向于发生鳄鱼形成的入口厚度到厚度减小区域。
