摘要： The invention provides a method of splicing rolled plates with each other, including the steps of (a) positioning a rear end portion of a leading rolled plate above a front end portion of a following rolled plate by a distance slightly greater than a diameter of a cylindrical cutter having a rotation axis extending in a width-wise direction of the leading and following rolled plates, the positioning being carried out while the leading and following rolled plates are being transferred, (b) cutting an upper surface of the front end portion of the following rolled plate with the cylindrical cutter only within a region at which the following rolled plate is to be spliced with the leading rolled plate, the cutting being carried out in a direction F in which the rolled plates are being transferred, (c) blowing a first reducing flame to the upper surface being cut from above the upper surface in the direction F while the step (b) is being carried out, (d) cutting a lower surface of the rear end portion of the leading rolled plate only within a region at which the leading rolled plate is to be spliced with the following rolled plate, the cutting being carried out in a direction R opposite to the direction F after the step (b) has been completed, (e) blowing a second reducing flame to the lower surface being cut from below the lower surface in the direction R while the step (d) is being carried out, and (f) splicing the leading rolled plate with the following rolled plate by compression at the region after the step (d) has been completed, the reducing flames being blown to both the upper surface of the front end portion of the following rolled plate and the lower surface of the rear end portion of the leading rolled plate until the splicing are completed. The invention also provides an apparatus for carrying out the above mentioned method.

摘要翻译： 本发明提供了一种将轧制板彼此拼接的方法，包括以下步骤：（a）将先导轧制板的后端部分定位在稍后大于直径的 圆柱形切割器具有在前后轧制板的宽度方向上延伸的旋转轴线，同时在前进和后续轧制板被转移时进行定位，（b）切割前端和后端轧制板的前端部分的上表面 下面的带有圆筒形切割器的轧制板仅在下一个轧制板与导向轧制板接合的区域内，切割是沿轧制板转移的方向F进行的，（c）吹制 在执行步骤（b）的同时，在方向F的上方从上表面切割到上表面的第一还原火焰，（d）切割后面e的下表面 只有在先导轧制板要与后续轧制板拼接的区域内，在步骤（b）完成之后，在与方向F相反的方向R上执行切割， （e）在进行步骤（d）的同时，向R表面下方从下表面吹出第二还原火焰，并且（f）用先后的轧制板将后面的轧制板拼接 在步骤（d）之后的区域的压缩已经完成，还原火焰被吹送到随后的轧制板的前端部的上表面和前轧制板的后端部的下表面，直到 拼接完成。 本发明还提供了一种用于执行上述方法的装置。

摘要： A direct rolling method and apparatus for a continuously cast slab of steel includes carrying out preliminary rolling of a continuously cast steel slab with a surface temperature of the slab in the range of 900.degree.-1200.degree. C. at a strain rate of 10.sup.-3 to 1 sec.sup.-1 with a total reduction of greater than 5% and at most 20%. The slab is then subjected to hot rolling after the preliminary rolling.
