The German 3MA (micro magnetic, multi parameter, microstructure, and stress analysis) non-destructive testing technology widely used in the mechanical industry can achieve fully automatic measurement of data performance strength and integrate the testing equipment into consumer processes. It has the advantages of fast measurement speed and the ability to stop 100% inspection of products. The following four micro magnetic measurement techniques have been separated:

Analysis of tangential magnetic field harmonics

Analysis of Magnetic Barkhausen Noise

Analysis of incremental magnetic permeability

Multi frequency eddy current impedance analysis

The necessity of the 3MA-OMP online non-destructive measurement system for the mechanical properties of steel plates, including fully automatic testing, non-destructive testing, tensile strength, yield strength, elongation, hardness, etc

With the fierce competition in the steel market such as strip steel, sheet steel, steel pipe, hot and cold rolling steel, and automotive plate, the demand for mechanical properties of steel in the customer market is constantly increasing, and the level of testing of mechanical properties of steel plates by steel mills' consumer units also needs to be improved from time to time. Traditional destructive data experiments involve both time delays and data loss, as well as the discontinuity of laboratory testing; Unable to continuously (online) obtain the quality characteristics of the strip steel corresponding to the consumption process parameters. Moreover, this destructive sampling method can only stop detecting the head and tail of the steel coil, and cannot obtain the mechanical characteristics of the entire steel coil. Therefore, integrating a set of automated online non-destructive testing system 3MA-OMP for mechanical properties on consumer lines such as strip steel, thin plate, steel pipe, hot and cold rolling steel, and automotive plate can continuously and in real time provide reliable tensile strength Rm and yield strength Rp0.2 values, elongation, and hardness values for the entire steel coil. This helps consumers to timely and effectively discover the trend of mechanical properties of steel plates, thereby improving the control ability of production quality, reducing production quality problems, and directly modifying the consumption process itself or gradually optimizing the subsequent consumption process based on real-time values.

Quickly and continuously monitor the mechanical strength of entire coils of strip steel, thin plates, steel pipes, hot and cold rolling steel, automotive plates, etc. in real-time throughout the entire process. Based on measurement data, at least the following important tasks can be completed:

• (1) Quickly, non destructively, and simultaneously measure multiple quality related indicators: hardness, tensile strength, yield strength, elongation, etc.

(2) Analyze the causes of quality defects, identify the sources of errors in processes and equipment, and continue to address performance defects.

(3) Further dispose of partially defective strip steel, thin plates, steel pipes, hot and cold rolled steel, automotive plates, etc., remove non-conforming parts, and improve the application rate of data.

(4) Stop timely disposal of the consumption line according to the practical situation of mechanical characteristics, prevent unqualified products from leaving the factory, and effectively reduce quality problems.

(5) Tailored according to detailed measurement requirements (probe design, analysis software, database disposal, etc.)
