A calculation model and method of the crossslab in the box girder is obtained by the bridge 3D-analysis of the continuous concrete box girder under dead and live load.
In this stage semifinished products with smaller cross sections are produced, such as slab, bloom or billet, which are suitable for further rolling.
这个阶段的产品是横断面较小的半成品,如板坯、大钢坯、小方坯等。这些半成品适合于进一步轧制。
