201110347172.2, it would be desirable to which then compound substrate, compound plate polishing lay explosive on compound plate, produced by explosive charge
Raw impact force carries out compound, the clad steel plate Percentage bound of the production technology of this Explosion composite production and strong by compound plate and substantially
Spend it is relatively low, and with high noisy pollution, be in the state being phased out at present.
The patent " a kind of martensitic stain less steel clad steel plate and its production method " of Shoudu Iron and Steel Corp.'s application, number of patent application
For：201610180116.7, by steel billet assembly, heating, controlled rolling, heat treatment process route complete, using double base ply rolling, i.e., on
Lower two layers is A516Gr70 carbon steels, and intermediate two layers is 410S martensitic stain less steels, be added between two layers of martensitic stain less steel every
From welding edge sealing to four sides of composite slab progress after agent and being vacuumized using vacuum pump, there is excellent obdurability and mechanical property；
But the technique of its symmetrical assembly is relative complex, and is vacuum-treated.A kind of another patent " carbon of Shoudu Iron and Steel Corp.'s application
Steel and austenitic stainless steel clad steel plate and its production method ", number of patent application is：201510162301.9 also using upper
Technique is stated, intermediate two layers is 316L austenitic stainless steels, is added after interleaving agent to composite slab between two layers of austenitic stainless steel
It carries out four sides welding edge sealing and is vacuumized using vacuum pump, the technique of its same symmetrical assembly is relative complex, and needs to carry out true
It manages in vacancy.
《A kind of production method for producing steel nickel nickel-base alloy composite blank》(publication number：CN104801562A it) introduces
A kind of preparation method for the composite blank preparing nickel-base alloy composite plate for rolling, wherein the phosphorus content of carbon steel layer exists
0.01-0.10%, production efficiency is high, and adaptation capacity of equipment is strong, and it is compound steel nickel/nickel-base alloy can be further made by the blank
Plate.But this method is also to be vacuum-treated, and increases intractability and time.
Invention《The explosion welding method of nickel-based alloy composite steel plates》(publication number：CN101559527A explosion method) " is used
The nickel-base alloy composite plate of preparation, it is effectively that nickel-base alloy plate and general steel plate is compound, to ensure that clad steel plate has
Under the premise of all advantages of nickel-base alloy, have the intensity of needs, to save the usage amount of expensive metal.But it is quick-fried
Serious noise pollution is formed to surrounding enviroment during the composite plate of fried welding production, has been gradually backed out the arena of history.
By comparing patent above it is found that being presently available for the steel plate or the following deficiency of composite plate presence of bridge construction：
1, blank is required to be vacuum-treated in preparing, and increases process, reduces efficiency；
2, explosion method is not necessarily to vacuum, but efficiency is low, seriously polluted.
Invention content
Based on above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of simple production process, clean environment firendly, nothings
The low-cost high-efficiency assembly production method for the composite plate that need to be vacuum-treated.
Technical solution provided by the invention is a kind of low-cost high-efficiency assembly production method of composite plate, including Substrate sheet
With clad sheet steel milling, stack, preheat, assembly welding, filling with inert gas, seal welding, heating, rolling, specially：It is right respectively
One surface of clad sheet steel and Substrate sheet carries out milling processing, through being preheating to 150 after milling face is stacked together relatively
DEG C~200 DEG C, to remove the steam of contact surface, reduce atmospheric density and oxygen content in gap, then the surrounding of contact surface is carried out
Welding, there are φ 5-30mm holes at solder up, by inert gases such as the inside applying argon gas of hole, finally again with aluminum strip by hole
Hole blocks, and can prevent contact surface in 660 DEG C or less heating processes from being aoxidized, and when heating 660 DEG C or more, aluminum strip melts, internal
High pressure gas is excluded by hole, can prevent from bursting in steel plate deformation of cylindrical and the operation of rolling.This method is not necessarily to true
It welds in empty room, is vacuumized without in postwelding, significantly increase working efficiency, reduce equipment investment and floor space.
