Embodiment 1

[0049] A method for manufacturing a hull, comprising the steps of:

[0050] (1) Prepare the steel for manufacturing the hull, the steel contains C, Mn, Si, P, S, AlS, Cu, Cr, Ni and Fe, and the mass percentage of each component is C0.01%, Mn0.60%, Si0.10%, P0.01%, S0.01%, AlS0.015%, Cu0.01%, Cr0.01%, Ni0.01% and the rest are Fe;

[0051] (2) Straightening the steel plate made of the steel in step (1) with a leveler, and leveling the steel plate through the leveler back and forth at least once;

[0052] (3) Straightening the straight profiled steel made of the steel in step (1) using a profile straightening machine;

[0053] (4) Pre-clean the surface of steel: pickling of raw materials, degreasing, pickling, rust removal, cold water washing, neutralization treatment, second cold water washing, phosphating treatment, hot water washing, natural drying, replenishment processing, second natural drying for cleaning;

[0054] (5) Perform secondary derusting on the pre-cleaned stee...

Abstract

The invention relates to the boat manufacturing field, in particular to a method for manufacturing a boat. The method for manufacturing the boat includes the steps of rolled steel flattening, welding assembling, surface pre-cleaning, secondary rust removal, electroplating and protection layer covering, and the problem that the boat is easily corroded in water is solved; meanwhile, the boat is abrasion resistant and high in strength, and the service life is accordingly prolonged.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for manufacturing a hull. Background technique [0002] About 71% of the earth's area is ocean, and ocean resources are very rich, but because the area of ​​the ocean is too large [0003] Therefore, it is necessary to use various ships to shuttle in the ocean. If the ship sails in the ocean for a long time without maintenance [0004] When the ship is damaged, the hull is easily corroded or attached by seawater, ocean atmosphere and marine organisms, which affects the safety and stability of the ship's navigation. [0005] Qualitative. [0006] In order to prevent the corrosion of the draft part of the hull or the influence of the ship's navigation from the adhesion of aquatic organisms, it is necessary to [0007] Surface timing treatment generally adopts painting or electroplating methods in the prior art. If the method of spraying paint is used to improve the appearan...
