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： A method for reducing the thickness of a slab of metal under conditions which tend to cause alligator defects to occur. The method comprises the steps of directing a relatively thick slab of metal several times through a rolling mill or mills to incrementally reduce the thickness of the slab until the thickness approaches a value that tends to produce a longitudinal and lateral fracture in one or both ends of the slab. The thickness of the slab is further reduced by passing the same several times again through a rolling mill or mills, with each of the passes of the slab taking a decreasing amount of reduction in thickness until a predetermined thickness value is reached. The next step involves passing the slab again through a rolling mill to further reduce the thickness thereof, the amount of reduction in this step and pass being substantially greater than that of the last pass immediately preceding this step.
摘要翻译： 一种在倾向于引起鳄鱼皮缺陷的条件下减小金属板厚度的方法。 该方法包括以下步骤：通过轧机或磨机将相对厚的金属板多次引导以递增地减小板坯的厚度，直到厚度接近趋于在一端或两端产生纵向和横向断裂的值 板块。 再次通过轧制机或轧机再次进行多次轧制，使板坯的厚度进一步降低，板坯的每个通道的厚度减小量减小，直到达到预定的厚度值。 下一步包括再次通过轧机将板坯通过轧机进一步减小其厚度，该步骤和通过量的减少量基本上大大高于该步骤之前的最后一次。

摘要： A structural panel for building structures such as residential houses or the like comprises a honeycomb or other cellular core sandwiched between two metal face sheets and surrounded by a metal frame. Frame members of the frame form mechanical interlocking connections with the face sheets of the panel. Side frame members of the panel define interlocking protrusions and channels for making interlocking joints between panels. A building structure employing the panels for forming floor and roofs includes brackets that extend into a gap between the side frame members of the panel at the panel joints and attach to the side frame members. The brackets are used for attaching the panels to other parts of the structure.
