MULTI-SEGMENT SHELL SECTIONS Trial fit-up of a multi-segment dome for a blast-furnace hot-stove(Dishing radii from 3.362 mm up to 6.430 mm, length 17.100 mm, height of the largest spherical section 6.430 mm, Steel grade 15Mo3) 20
When the required items exceed the dimensions of the one-piece component, they can be produced in multi-segment design, each pressing being supplied ready for assembly; the individual sizes of the segments can be also agreed upon. Manufacturing process The pressings comprising a multi-segment shell are individually formed using tool equipment, the profile of which suits the contour of the part being made. The knuckle segments of torispherical heads are basically hot-pressed; as are the relative crown segments and any pressings designed with a dishing radius up to approximately 3.500 mm; above this diameter cold-forming is applied. The weld-edges of the shaped segments are produced by flame cutting. Scope of supply It includes mainly the fabrication of torispherical heads to DIN 28011 or NF E 81-102 and DIN 28013 or SMS-482 above 4.450 mm in outside diameter and spherical heads above 3.650 mm in outside diameter; the multi-segment design can be also extended to „tailor-made“ shell sections suiting a specific shape i.e. transition pieces, reversible conical segments and inlets for shaft lining since no dimensional restriction must be observed. The multi-segment design is an alternative to Heavy Fabrication Division Dillinger Hütte GTS, Multi-segment shell sections [1/3], 2008 21 the fabrication of items outside the manufacturing range of the cold spinning process which is mainly restricted to the shaping of wall thicknesses up to around 30 mm. Please refer also to the Technical Delivery Conditions on page 32. Trial fit-up The pressings are produced to fabricate multi-segment heads or other large shell sections. When requested, the segments are trial assembled for the shop inspection by using key-plates and pins; clamping cams can also be welded on which you can later put to advantage as erection aids during the final assembly.
