摘要： When roughing a continuously cast slab in a continuous hot rolling stand, the invention breaks down the width of the slab, having passed through a vertical scale breaker, by means of rolls having at least a pair of pressing calibers and thereafter the width of the slab is rolled by means of vertical rolls whereby the width of the slab is rolled more accurately than was possible in the prior art, and accordingly changes of molds of continuous casting machines are no longer required during the continuous casting operation and such an operation is possible over many charges.

摘要翻译： 当在连续热轧机中对连续铸造的板坯进行粗加工时，本发明通过具有至少一对加压口径的辊分解通过垂直断屑器的板坯的宽度，此后，板坯的宽度 通过垂直辊轧制，从而与现有技术相比，板坯的宽度更精确地滚动，因此在连续铸造操作期间不再需要连续铸造机的模具的变化，并且这样的操作可能超过 许多收费。
