The invention discloses a super-thick and super-large-diameter single shell. A nuclear submarine with the super-thick and super-large-diameter single shell is manufactured by taking a navy nuclear submarine as an example, and is characterized in that a super-large-diameter water-cooling crystallizer mold is established, a non-magnetic steel material is added into metallic titanium to form an impurity-free pure titanium alloy steel finished product, a loop is formed by a power system through a consumable electrode, the consumable electrode is fused and cast in a crystallizer mold under the action of a controller to complete an ultra-thick and ultra-large-diameter circular submarine subsection body, a rolling device is established on a slipway to perform electroslag automatic welding, and meanwhile, internal stress of a small semi-circular auxiliary rib body in the subsection body is strengthened to perform welding, and deep diving and submerging are safer.
本发明一种超厚超大直径单壳体是以海军核潜艇为例,制造超厚、超大直径的单壳体的核潜艇,其特征在于建立超大直径的水冷结晶器模具,将无磁钢材质加入金属钛形成无杂质的纯净钛合金钢成品,且以此为自耗电极由电力系统形成回路,使自耗电极在控制器的作用下,在结晶器模具内熔铸完成超厚超大直径园形潜艇分段体,且在于船台建立滚动装置做电渣自动焊接,同时将分段体内部小半园助肋体加强内应力而进行焊接,使深潜潜航更加安全。
