When the test piece is placed near a coil with alternating current, the alternating magnetic field entering the test piece can induce an eddy current (eddy current) flowing in the direction perpendicular to the excitation magnetic field in the test piece. A magnetic field opposite to the direction of the excitation magnetic field will be generated

Liquid penetration testing is used to check various opening defects on the surface of castings, such as surface cracks, surface pinholes and other defects that are difficult to find with the naked eye. The commonly used penetrant inspection is color inspection, which is to wet or spray a colored (usually red) liquid (penetrant) with high penetrating ability on the surface of the casting.

Since the horizontal continuous casting process can obtain a relatively dense matrix structure, the oil pressure resistance and air tightness of horizontal continuous casting profiles are higher than other engineering materials. It can be said that the use of horizontal continuous casting profiles to make hydraulic parts is an ideal material so far . In addition to high production rate and low production cost, it also has better machining performance than steel. This is because in the cutting process, the cutting resistance is reduced due to continuous chipping.
