Abstract

The invention discloses a manufacturing method of a duplex stainless steel chemical ship side section and belongs to the technical field of ship construction. The method includes the following steps of firstly, carbon steel outer plate secondary medium assembly construction, secondly, stainless steel inner longitudinal wall plate secondary medium assembly construction, thirdly, inner longitudinalwall plate flat straight section medium assembly construction, fourthly, deck medium assembly construction and fifthly, ship side section large assembly combination. In the method, when stainless steel inner longitudinal wall plate secondary medium assemblies are constructed, stainless steel molding beds are adopted, and carbon pollution caused by a common carbon steel material to a duplex stainless steel material can be effectively prevented; and through reasonable selection of the assembling sequence and the assembling pose, an automatic angle welding machine can be conveniently used for welding stainless steel, deformation of the duplex stainless steel is effectively reduced, the duplex stainless steel ship side section is divided into flat straight section medium assemblies and deck medium assemblies, the modes of same molding bed construction and medium assembly separate combination are used, the construction accuracy is guaranteed, and section construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to a method for manufacturing side sections of duplex stainless steel chemical tankers. Background technique [0002] A duplex stainless steel chemical tanker is a high-tech, high-value-added ship. The side section structure of the duplex stainless steel liquid cargo tank is complex, and the duplex stainless steel materials contained in it account for a large proportion. During the construction of the stainless steel side section, because its inner longitudinal wall is made of duplex stainless steel, it cannot be in contact with ordinary carbon steel, otherwise there will be a risk of carburization. [0003] In the process of welding stainless steel, deformation is extremely easy to occur. Since the thermal expansion coefficient of duplex stainless steel is higher than that of ordinary carbon steel, its welding deformation is much higher than that of ordinary carbon steel, and ...
