In the manufacturing process of stainless steel composite plate, cleaning the appearance of steel plate is an important condition to obtain a good contact interface.
The composite interface is an important part of the stainless steel composite plate. The load transfer face of the information industry, the improvement of stress, strain, residual stress, mechanical and cracking processes in the cell, as well as the thermal conductivity and other physical and mechanical properties have an important role and influence.
The manufacturer of the steel stainless steel composite plate believes that the appearance of the plate is free from dust, moisture, oxides and other pollutants, which will prevent the stainless steel coating from being used for the contact of the bottom low carbon steel or low alloy steel, so the surface treatment of the contact treatment plate shall be conducted to remove the appearance of the adsorption layer and oxide layer.
However, the contact strength of the composite interface decreases because the interface is easy to oxidize during high temperature hot rolling. The interface strength of the composite plate increases after the interface contact oxidation is decreased.
The manufacturers of stainless steel composite plates think that China is a heavy energy source. Taking the information science research of this kind of stainless steel and low alloy steel composite plates as the research object, optical microscope and scanning electron microscope (SEM) are used to analyze the composite interface.
It is found that the dopant at the interface of stainless steel composite plate is mainly oxide, and its composition is vacuum at the interface with compound.
At low vacuum degree, the vacuum degree is more than 15 PA, the composition of oxide is mainly mixed with silicon; at high vacuum degree (vacuum degree is less than 0.1 PA), the composition of mixture is mainly mixed with aluminum.
The interface oxide is mixed with aluminum, silicon, manganese and other elements, as well as the oxidation compound caused by the interface thermal dispersion.
Secondly, the experimental results also show that the oxidation interface becomes more and more obvious with the decrease of vacuum degree. The volume fraction of oxide increases from 15% to 50% when the real void degree increases to 2000.1 bar.
