Description
Technical field
The invention belongs to Explosion composite technical fields, and in particular to a kind of explosive clad plate heat treatment clad surface oxide layer
Processing method.
Background technique
The prior art uses the composite metal plate of explosion method manufacture, since explosive clad plate destroys normalizing shape in explosion time
The reasons such as state, are heat-treated.During heat treatment, if the protection of inert free gas is after Overheating Treatment, cladding
Metal surface can generally generate the real fine and close oxide layer of a thickness, oxide skin is commonly called as, according to oxide skin explosive clad plate cladding material
The difference of the content ingredient of matter, the color for generating oxide skin have black, grey even green etc..Composite plate multi-layer metal heat treatmet
When usually require for temperature to be heated to 500 DEG C or more, and if it is intended to whole in heat treatment carry out gas shield, to heat treatment
Technique and equipment requirement it is very high, cost is also higher, most producers and the unpowered production method using gas shield.
Except the method for descale generally has 3 kinds:
1, Mechanical Method carries out physics polishing that is, using equipment such as polishing wheels, grinds off the oxide layer of clad surface, exposes metal sheet
Matter；This method can generate more loss in the not high situation of mechanical precision to cladding, and need to usually be polished for a plurality of times, production
Efficiency is lower.
2, chemical method is applied to clad surface using passivating agent for acid-washing, and the oxide layer on surface, dew are removed using chemical reaction
Metal essence out；The method operation is relatively simple, but to consume a large amount of passivating agent for acid-washing, and environmental pollution is more serious.
3, chemical method+Mechanical Method, i.e. in summary 1,2 two methods, first carry out acid wash passivation, then mechanically polished.
The early investment of the method is larger.
In addition, the generation of Hydrogen Brittleness Phenomena should be avoided in the chemical pickling of the materials such as steel.Hydrogen embrittlement is dissolved in steel
Hydrogen is polymerized to hydrogen molecule, and stress is caused to concentrate, and more than the strength degree of steel, tiny crackle is formed inside steel, also known as white
Point.Hydrogen embrittlement is only anti-, uncurable disease.Hydrogen embrittlement is not just eliminated once generation.In the smelting process of material and the manufacture of part and dress
With process (as plating, welding) in enter steel inside Microamounts of Hydrogen (10 minus 6 power magnitudes) it is internal residual or it is outer plus
Stress under cause material embrittlement even crack.When pickling, the hydrogen of generation plays mechanical stripping to substance hard to tolerate and falls off
Effect, is conducive to clean, but atomic hydrogen penetrating into metallic matrix also has the side effect of hydrogen embrittlement.
In view of this, it is necessary to propose that one kind can prepare multiple Explosion composite sheet metals simultaneously, can effectively eliminate or subtract
The equipment and its application method of few boundary effect.
