Method for treating oxide layers of multilayer heat treatment surface of explosive composite plate

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 [0001] The invention relates to a process method for eliminating the oxide layer on the surface of the heat-treated clad layer of an explosion-proof composite plate. Background technique [0002] In the prior art, the metal clad board manufactured by explosion method, after heat treatment, will generally form a layer of black, thick and dense oxide layer on the clad metal surface, commonly known as "oxidized skin". During explosive recombination, due to the high temperature of the explosive products, the properties of the clad metal surface substances are affected. Due to the extremely short action time (in milliseconds), this effect is not obvious, but it will be evident in the subsequent heat treatment. After heat treatment, the clad metal of the composite board is severely oxidized on the surface, forming a layer of thick and dense black oxide skin, usually with a thickness of 0.1-0.2mm. This layer of oxide skin is very dense and smooth. In actual produ...

Problems solved by technology

[0006] It is difficult to polish by mechanical method, and it often needs to be repeatedly polished and polished 3 to 4 times, which is very labor-intensive; chemical method needs to consume a lot of pickling passivation agent, and it also needs to be repeatedly scrubbed with a wire brush, which is often not clean enough. Clean, leaving speckled traces, affecting the appearance

Due to the thicker oxide scale, the removed thickness is also larger, and the thickness loss of the clad layer is larger

The above-mentioned three methods all exist, and the disadvantages of large consumption of manpower and material resources and high labor intensity
