厚钢板一般是要求厚度均匀一致。新日本制铁公司打破这种旧框框,开发了一种新的差压波形厚钢板。这种钢板的主要特点是对承受外力大的部位进行重点强化,因而可防止整个构造件产生挠度,保证各部位的等强度。在板材压延时,板厚的调整通过压力计控制而呈周期性变化,其变化范围为16～22毫米。波的间距为900毫米以上。这种钢板用于制造大型油轮时,可使油轮重量减轻15～20％。
Thick steel plate is generally required uniform thickness. Nippon Steel Corporation to break this old box, developed a new differential pressure waveform thick steel plate. The main feature of this steel plate is to emphasize the parts subjected to large external force so as to prevent deflection of the entire structural part and ensure the equal strength of all parts. In the sheet rolling, the thickness adjustment through the pressure gauge control and cyclical changes in the range of 16 to 22 mm. Wave spacing of 900 mm or more. When used in the manufacture of large tankers, this steel plate can reduce the weight of tankers by 15 to 20%.
