Description
Technical field
The invention belongs to composite plate manufacturing technology field, and in particular to a kind of big specification, thin cladding nickel-base alloy/pipe line steel
The preparation method of composite plate.
Background technology
Nickel-base alloy/pipeline steel composite board the corrosion resisting property good because possessing, particularly resistance to CO2And H2S corrosive natures and pipe
The high impact flexibility of line steel, therefore it is widely used in the industries such as petroleum pipeline, chemical industry, ocean engineering.
On the premise of performance is met, nickel-base alloy/pipeline steel composite board of thin cladding can further reduce manufacture
Cost.As China's economy constantly advances, the development trend for equipping maximization is more and more obvious, the Ni-based conjunction of thin cladding
The demand of gold/pipeline steel composite board is also increasingly urgent
Big specification, thin cladding nickel-base alloy/pipeline steel composite board are both needed using specific processing method so that it reaches
The requirement of required size, at the same be also required to ensure in process and meanwhile be also required to ensure in process nickel-base alloy and
The tissue and performance of pipe line steel all meet respective requirement.But, these current conventional production methods are producing big specification, Bao Fu
The problem of existing various in terms of layer nickel-base alloy/pipeline steel composite board.Such as produced using the method for centrifugal casting+rolling
Big specification, thin cladding nickel-base alloy/pipeline steel composite board complex process, while easily occur that inner surface quality is poor, hole size not
Accurately, the low problem of recovery rate of iron.Big specification, thin cladding nickel-base alloy/pipeline steel composite board are produced using explosive welding process
The problems such as easily there is edge unstability, regional area fusing and poor bond quality, particularly nickel-base alloy/pipeline of petroleum pipeline
Steel composite board, generally length >=10000mm, width≤2000mm composite plates, the simple explosive welding of composite plate of such specification
