First, Functions and Characteristics

Mainly used for aggregating the surface of the aluminium aqueous solution, making it easy to remove and ensuring the purity of the aluminium aqueous solution. It can also be used as a high-quality thermal insulation covering agent and slag-holding material, with a thick thermal insulation layer and excellent slag-holding performance, which can effectively insulate the air and prevent the secondary oxidation of the aluminium aqueous solution.

The aluminum deslagging flux industry does not burst, spreads quickly and evenly, and has strong slag gathering ability. It has the effective prevention of slag inclusion defects in castings, can improve the internal quality of castings, improve the yield of castings, reduce production costs; it has simple method of use, and can reduce labor intensity of workers, improve production efficiency.

Second, advantages of using methods

1. Slag Removal and Slag Retaining: High-efficiency Deslagging Fluxindustry can be used in ladles, tundishes and electric furnaces. When it is sprayed uniformly on the surface of molten liquor by artificial or spraying gun, the slag shell which is easily separated from the metal solution can be quickly assembled with a little agitation, and the pure solution can be obtained by removing the slag shell, thus avoiding slag inclusion in castings and improving the quality of castings. And there is no explosion, no splash, no sticky package, no wall hanging. If slag retaining is needed, slag agglomerating agent can be added at the pouring ladle or furnace mouth before slag removal and casting, forming strip floating dam, sticking sporadic slag, eliminating manual slag retaining, reducing labor intensity and improving production efficiency.

2. Insulation covering: The thermal conductivity of high-efficiency deslagging flux for aluminium industry is low. Forming a good insulation layer on the surface of molten metal can reduce the heat loss of solution, which is an excellent thermal insulation covering agent for intermediate subcontracting or metal solution which needs to be parked for a long time.

3. Environmental protection: The high-efficiency deslagging flux for aluminium industry has no pollution and penetration to the molten metal, which does not affect its chemical composition and mechanical properties of castings. There is no smoke, dust and harmful gas pollution, which can purify the environment, and achieve the civilized production.

4. Dosage: The amount of high-efficiency slagging agent is generally 1-3 kg/T of metal solution, which can be increased or decreased according to the size of melt area, the temperature and impurity content of smelting metal.

Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the magnetization of ferromagnetic components. In the magnetic non-destructive testing, magnetization is the first step to realize the detection, which determines whether the leakage magnetic field signal can be generated, and also affects the performance characteristics of the detection signal and the structural characteristics of the detection device.  Like magnetic particle inspection, magnetization is achieved by a magnetizer, including both a magnetic source and a magnetic circuit.  The magnetic source and the magnetic circuit change depending on the structure of the member to be tested.

What kind of magnetization can be divided into several categories? The magnetization methods can be generally divided into five categories, namely, alternating current magnetization mode, direct current magnetization mode, permanent magnet magnetization mode, composite magnetization mode, and integrated magnetization method.

What are the characteristics of magnetic flux leakage detection technology?

Because leakage magnetic field detection uses magnetic sensors to detect defects, compared with magnetic powder, penetration and other methods, the magnetic flux leakage equipment has the following advantages:

1. It is easy to realize automation. The computer judges the presence or absence of defects based on the detected signals.

2. The fundamentally high detection reliability can solve the influence of human factors in the magnetic powder and osmosis method, and has high detection reliability.  

3. can achieve preliminary quantification of defects.  In the range of wall thicknesses up to 30 mm, the inner and outer wall defects can be detected simultaneously.  In the detection of the pipeline, 5 high-efficiency, pollution-free automated inspection can achieve high detection efficiency.

Electromagnetic detection is a very important non-destructive testing method and is widely used. Magnetic flux leakage testing is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic magnetic flux leakage principle is used to magnetize the steel. When used in combination with other methods, it provides a quick and inexpensive assessment of the workpiece of ferromagnetic materials. With the advancement of technology, people are paying more and more attention to the automation of the inspection process. This not only reduces the labor intensity of the inspection work but also improves the reliability of the test results and reduces the influence of human factors. The MFI magnetic flux leakage inspection method is a highly automated magnetic detection technology. The principle is that after the ferromagnetic material is magnetized, the surface and near-surface defects form a leakage magnetic field on the surface of the material, and defects are detected by detecting the leakage magnetic field. In this sense, the magnetic particle detection technology commonly used in pressure vessel inspection. However, it is customary to use the method of measuring the leakage flux with a sensor as the magnetic flux leakage detection, and the magnetic flux to detect the leakage flux. The method is called magnetic particle detection and they are juxtaposed into two detection methods.

Magnetic flux leakage testing can only detect surface and near-surface crack defects, and it needs surface grinding when testing. It is only suitable for the detection of workpiece discontinuation. In addition to the surface and near-surface crack defects, the MFI magnetic flux leakage inspection can also find the corrosion inside the workpiece from the outside. Defects such as pits, and do not need to be polished on the surface of the workpiece, suitable for on-line inspection of workpieces. On-line inspection of workpieces is currently the most urgent method for users, which can reduce unnecessary parking and reduce inspection costs. In addition, the magnetic flux leakage detection can also quantify the depth and length of defects. Although the application of magnetic flux leakage detection technology is rarely used in workpiece inspection, it has the advantages that magnetic particle detection does not have, so its application prospect is very broad.
