Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for CCSA bulk freighter steel and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
The advantages of flame cutting are simple cutting and low cost. The disadvantage of flame cutting is that when cutting thin plates, cutting deformation problems are prone to occur, and the materials that can be cut have certain limitations. The advantage of CNC cutting is that it can cut CCSA bulk freighter steel and any complex parts with high cutting accuracy. The disadvantage of CNC cutting is that there are certain operational and technical requirements.
