Abstract

The invention discloses a manufacturing method of a tank top steel skin plate of a large-scale stainless steel tank. The manufacturing method is characterized by comprising the following steps: a, drawing an arrangement drawing of the tank top steel skin plate according to the design working drawing of the large-scale stainless steel tank; b, conducting blanking according to the arrangement drawing of the tank top steel skin plate, cutting steel plates and carrying out weld preparation, conducting machining or carrying out automatic and semi-automatic flame cutting machining, and carrying out manual flame cutting machining on the circular arc edge of the tank top steel skin plate; c, designing an arc sample plate of the tank top steel skin plate according to the 60-degree central angle of the spherical arched top of the construction drawing of the large-scale stainless steel tank; inspecting by the arc sample plate after the arc component of the tank top steel skin plate is machined and molded; and inspecting warpage of the tank top steel skin plate on a platform. The manufacturing method of the tank top steel skin plate of the large-scale stainless steel tank has the advantages of good formation degree of the tank top steel skin plate, capability of effectively ensuring the radian of the arched top plate and preventing the deformation and attractive appearance of the spherical spherical arched top.

Description

technical field [0001] The invention relates to a method for manufacturing a roof plate of a tank, in particular to a method for manufacturing a roof steel skin plate of a large stainless steel tank. Background technique [0002] Chinese patent CN1202807552U disclosed on March 20, 2013 a method for assembling tank roof chords and arched roofs, which includes a circular bottom plate on which at least one circular support concentric with the circular bottom plate is arranged , the height of the support gradually decreases from the inside to the outside. The circular bottom plate is provided with an inner fixing piece and an outer fixing piece concentric with the circular bottom plate, the inner fixing piece is located at the periphery of the support body, and the outer fixing piece is located at the outer periphery of the inner fixing piece. The inner fixing part and the outer fixing part are composed of fixing plates evenly arranged along the circumference, and the top chord...
