The trapezoidal groove is longitudinally disposed on steel plate 1.
The parameter of each component is in the steel plate 1：
In order to improve the intensity of Steel-aluminium composite board blast welding block, it is necessary to analyze steel is used so far first
The material of aluminum composite plate blast welding block, then goes used material so far to be improved and improved again.
Untill up to now, material used in existing blast welding block, steel plate below is Q235；The material of aluminium sheet above
Matter is Al1060.
Because the aluminum guide being connected above aluminium sheet 1060 and aluminium sheet is also 1060 same, then this material can after
Continuation of insurance, which is stayed, to be used.
If so want improve blast welding block intensity and electric conductivity, just can only by explode welding block below steel plate material
Q235 mass is improved and improved, and only allows the performance of this material close to after the material of aluminium sheet, two kinds of different materials,
What can be combined is more preferable, and what is only combined is more preferable, then intensity just can be higher.
By the screening to steel plate, find phosphorus content lower (phosphorus content ＜ is below 0.06) and purity it is higher (steel-making be through
Cross refining and vacuum metling) after, could be closer to the performance of aluminium sheet.
