工业锅炉受压元件中,集箱平端盖、矩形集箱筒板与平端盖、矩形断面环形集箱平端板(三浦锅炉)以及各种拉撑平板、支撑平板、有加固横梁的平板等皆属于平板元件。多年来,中外对承受压力作用的锅炉各种平板元件进行过较多研究。约占全日本工业锅炉总容量90%的三浦锅炉,由于其主要受压元件——矩形断面环形集箱采用外置式填角焊平端板结构,近些年日本三浦工业株式会社对其强度进行过深入的
Industrial boiler pressure components, the header flat end cover, rectangular header and flat end caps, rectangular cross-section ring header (Miura Boiler) and a variety of tension plate, support plate, plate with reinforced beams, etc. belong to Flat components. Over the years, China and foreign countries have carried out more studies on the various plate elements of boilers under pressure. Miura Boiler, which accounts for about 90% of the total capacity of all industrial boilers in Japan, has had its strength drastically exceeded by Miura Industrial Co., Ltd. in recent years due to the external fillet-welded flat end plate structure of its main compression element - of
