Abstract
The invention provides a method for treating oxide layers of a multilayer heat treatment surface of an explosive composite plate. The method includes: polishing the metal multilayer surface by the aid of a polishing tool before heat treatment of the explosive composite plate; and then carrying out heat treatment. The explosive composite plate is obtained by the aid of the technological method after heat treatment, the multilayer surface is transparent or semi-transparent and lightly brown and white, and an oxide cover is thin, appears similar to a 'floating rust' layer on the metal multiplayer surface, does not need to be treated or can be slightly treated by a mechanical method or a chemical method. The method is simple in process and convenient in operation, materials and working hours are remarkably saved, and loss of the thickness of the multilayer surface is greatly reduced. In addition, the oxide cover of the explosive composite plate can be effectively prevented during heat treatment, consumption of materials and consumption of working hours are reduced, labor intensity is reduced, and production cost is saved.
Description
Technical field
The invention relates to a kind of process of eliminating blast protection composite plate heat treatment clad surface oxide layer.
Background technology
The composite metal plate that prior art adopts explosion method to make, after Overheating Treatment, the plied timber surface generally can generate one deck black, abundant compact oxide, is commonly called as " oxide skin ".The blast compound tense because the high temperature action of explosion product, has produced influence to the character of plied timber surface mass.Owing to extremely lack action time by (with millisecond meter), this influence is also not obvious, but when follow-up heat treatment, this influence just significantly shows.Composite plate plied timber after heat treatment surface oxidation is serious, generates the black oxidation skin of the abundant densification of one deck, and thickness is usually at 0.1～0.2mm.This layer oxide skin is very fine and close smooth.In actual production, attractive in appearance for product appearance often need be removed in subsequent treatment.The method that subsequent treatment is removed descale generally has 3 kinds:
1, Mechanical Method promptly adopts equipment such as polishing wheel, carries out the physics polishing, grinds off the oxide layer of clad surface, exposes metal essence;
2, chemical method adopts passivating agent for acid-washing to spread upon clad surface, utilizes chemical reaction to remove the oxide layer on surface, exposes metal essence;
3, chemical method+Mechanical Method, promptly comprehensive above-mentioned 1,2 two kind of method carried out acid wash passivation earlier, carries out machine glazed finish again.
Adopt Mechanical Method to be difficult to polishing, often need repeat sanding and polishing 3～4 times back and forth, take very much manpower and materials; The employing chemical method need consume a large amount of passivating agent for acid-washing, and need firmly scrub repeatedly with wire brush, often pays off not wash clean, and stays flecky vestige, influences attractive in appearance.Because oxide skin is thicker, the thickness of removing is also bigger, and multiple layer thickness loss is bigger.Above-mentioned 3 kinds of methods all exist, and manpower and materials consumption is big, the weak point that labour intensity is high.
Summary of the invention
The objective of the invention is weak point, provide a kind of technology simple, easy to operate, and can reduce labour intensity and material and expenditure of time, eliminate the process of blast protection composite plate heat treatment clad surface oxide layer to above-mentioned prior art existence,
Above-mentioned purpose of the present invention can reach through following measure; A kind of processing method of explosive clad plate heat treatment clad surface oxide layer; Has following technical characterictic: before explosive clad plate heat treatment, the plied timber surface is polished, heat-treat then with polishing tool.
The present invention has following beneficial effect than prior art.
Adopt the explosive clad plate after the heat treatment that process of the present invention obtains; Clad surface presents the shallow palm fibre white of transparent or semitransparent shape; Oxide skin is very thin, and the plied timber surface only similarly is to have given birth to one deck " floating rust ", can not add to handle or adopt Mechanical Method or chemical method to handle a little to get final product.This method not only technology is simple, easy to operate, and can significantly reduce material and expenditure of time, reduces the explosive clad plate manufacturing cost and can also reduce labour intensity greatly.
This process is compared with the method that generally adopts at present, and technology is simple, and is easy to operate, practices thrift in material and man-hour obviously, and the loss of multiple layer thickness greatly reduces.Polishing before the heat treatment only needs 1 time.Handle as needing after the heat treatment, if adopt Mechanical Method, sanding and polishing gets final product for 1 time; If adopt chemical method, the consumption of passivating agent for acid-washing is original 1/2～1/3, and is easy to wash off.
The specific embodiment
Before explosive clad plate heat treatment, with polishing wheel or polissoir the plied timber surface to be polished, composite plate polished surface roughness is controlled at the 0.5um-50um scope.Through this processing, can effectively prevent the multiple layer of explosive clad plate when heat treatment, to produce oxide skin.Can remove the floating layer of oxidation that composite surface produces with physics or chemical method after the heat treatment.
Claims (3)
1. the processing method of an explosive clad plate heat treatment clad surface oxide layer has following technical characterictic: before explosive clad plate heat treatment, with polishing tool the plied timber surface is polished, heat-treat then.
2. the processing method of explosive clad plate heat treatment clad surface oxide layer according to claim 1 is characterized in that composite plate polished surface roughness is controlled at the 0.5um-50um scope.
3. the processing method of explosive clad plate heat treatment clad surface oxide layer according to claim 1 is characterized in that, can remove the floating layer of oxidation that composite surface produces with physics or chemical method after the heat treatment.
