[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The present application provides a debugging method for a magnetic storage device.

[0029] like Figure 1As shown, in one embodiment of the present application, a debugging method of a magnetic storage device includes:

[0030] S100, call the initial recipe for theoretical calculation.

[0031] Specifically, the theoretically calculated initial formula is ferric oxide: manganese oxide: zinc oxide = 53.5:36.5:10 (mol%), which is converted into a weight ratio of approximately 70:20:10 (wt%).

[0032] The main formula of power ferrite materials is generally ferric oxide: manganese oxide: zinc oxide = 50:37:13 (mol%).

[0033] S200, based on the initial recipe, selects a raw material.

[0034] S300, select a reference value.

[0035] Specifically, the main formula raw materials generally require that the purity of ferric oxide is above 99.5%, the purity of manganese tetraoxide (in terms of Mn) is above 71.5%, and the purity of zinc oxide is above 99.8%.

[0036] S400, forming a test formula using the reference value of the raw material and the initial formula.

[0037] S500, performing red vibration on the raw materials of the test formula, rolling the raw materials after red vibration, pre-burning the rolled raw materials, and black vibration on the pre-burned raw materials.

[0038] S600, sand grinding and stirring the raw materials after black vibration, spraying the raw materials after sand grinding and stirring, mixing and molding the sprayed raw materials, and sintering the molded raw materials.

[0039] S700, inspect the fired finished product.

[0040] S800, returning to the process of selecting a reference value until all reference values ​​are selected.

[0041] S900, returning to the initial formula, selecting a raw material until all raw materials are selected.

[0042] The present embodiment relates to a debugging method for a magnetic storage device. By calling the initial formula of theoretical calculation, the raw materials can be selected one by one, and each selected raw material can be tested for quality control. By using the method of controlling a single variable, the tested raw material can be included in all the raw materials of the test formula. The manufacturing process of the magnetic storage device is actually the process of material sintering. Red vibration, sheet rolling, pre-burning, black vibration, sand milling, spraying, mixing and molding are the core steps in the process of material sintering. Full-cycle monitoring and adjustment of the parameters of the material sintering process of the selected raw materials is beneficial to controlling the influence of the raw materials on the initial formula of theoretical calculation, and then achieving the yield rate of the material characteristics of high pressure resistance after the magnetic storage device is fired.

[0043] In one embodiment of the present application, before S100, the following steps are included:

[0044] S110, selecting a raw material in the initial formula.

[0045] Specifically, taking the selected raw material ferric oxide as an example, the physical and chemical indicators of the raw material are specific heat of generally 800 (J / kg·K), thermal conductivity of 1 to 5 (W / m·K), and linear expansion coefficient of 1.2 to the negative fifth power of 10 (1 / K).

[0046] S120, determining the physical and chemical indicators of the raw material based on the analysis data of the analysis instrument.

[0047] In fact, in addition to the thermal properties of ferric oxide affecting the high voltage resistance of magnetic storage devices, its own crystal phase structure will also have a certain impact.

[0048] Ferrous oxide generally has a spherical structure, a nearly spherical structure, etc. When ferrous oxide is mixed with other raw materials, various particles begin to connect, the bonding necks between particle clusters grow, the pore channels between particle clusters close, the gaps spheroidize, the pores shrink, and the pores coarsen.

[0049] S130, determining whether the physical and chemical index is within the index range of the initial formula.

[0050] S140, if the physical and chemical index is within the index range of the initial formula, return to selecting a raw material in the initial formula until all raw materials are selected.

[0051] S150, if the physical and chemical index is not within the index range of the initial formula, the early warning program is executed, and the process returns to selecting a raw material in the initial formula until all the raw materials are selected.

[0052] This embodiment involves the analysis of the physical and chemical properties of raw materials. The stability of the benign electromagnetic properties of the sintered particle group can be achieved through the thermochemical properties of each raw material and the ratio of different crystal phase structures of the same raw material.

[0053] In one embodiment of the present application, S500 includes:

[0054] S511, performing batching operation on the raw materials according to the test formula.

[0055] S512, performing red vibration on the batched raw materials.

[0056] S513, recording the system time when the red vibration starts.

[0057] S514, based on the predetermined red vibration time requirement of the test recipe, set the system time for stopping the red vibration.

[0058] S515, using the system time, determining whether the system time for stopping the red vibration has been reached.

[0059] S516: If the system time for stopping the red ringing has not been reached, continue to execute the red ringing.

[0060] S517: If the system time for stopping the red ringing is reached, the red ringing is stopped.

[0061] Specifically, the red vibration time is greater than or equal to a predetermined time length of the red vibration time of the test formula.

[0062] In fact, red vibration is the mixing of multiple raw materials at a preset temperature. Red vibration can shrink the pores of various raw materials inside the pellets. By setting the preset temperature and the preset red vibration time, the gaps between various raw materials inside the pellets can be controlled, thereby achieving better electromagnetic properties.

[0063] At the same time, as an oxidizing material, the raw materials will undergo different degrees of internal softening due to different thermal properties at the preset temperature. During the red vibration process, the softened raw materials can achieve adhesion, which will also improve the electromagnetic properties between the particle clusters.

[0064] In one embodiment of the present application, S500 further includes:

[0065] S521, receiving the raw materials after red vibration.

[0066] S522, performing sheeting operation on the raw material.

[0067] Specifically, rolling can improve the adhesion between individual particle clusters, thereby increasing the density of the overall material.

[0068] S523, determining whether the current of the machine performing the sheet rolling operation is within the current requirement of the test formula.

[0069] S524: If the current of the machine performing the sheet rolling operation is not within the current requirement of the test formula, the machine performing the sheet rolling operation is shut down.

[0070] S525, if the current of the machine performing the sheet rolling operation is within the current requirement of the test recipe, determine whether the oil pressure of the machine performing the sheet rolling operation is within the oil pressure requirement of the test recipe.

[0071] S526, if the oil pressure of the machine performing the sheet rolling operation is not within the oil pressure requirement of the test recipe, return to the step of determining whether the oil pressure of the machine performing the sheet rolling operation is within the oil pressure requirement of the test recipe, until the oil pressure of the machine performing the sheet rolling operation is within the oil pressure requirement of the test recipe.

[0072] S527, if the oil pressure of the machine performing the sheet rolling operation is within the oil pressure requirement of the test recipe, the machine performing the sheet rolling operation is shut down.

[0073] In fact, the detection of the oil pressure of the machine performing the sheet rolling operation is conducive to improving the control of the gap between the particle groups. In the firing step after pre-firing, there will be a process of reducing part of the oxide by reducing gas. In this step, the gap between the particle groups is particularly important. Controlling the oil pressure of the machine performing the sheet rolling operation can control the gap between the particle groups. After the metal oxide is reduced, the electromagnetic properties of the finished product after firing can be improved.

[0074] In one embodiment of the present application, S500 further includes:

[0075] S531, dividing the sheeted raw materials into multiple batches.

[0076] S532, selecting a batch of sheeted raw materials.

[0077] S533, select a pre-burning temperature.

[0078] Specifically, the pre-burning temperature is determined by a current frequency parameter of an electric furnace performing the pre-burning work and a coil magnetization parameter of the electric furnace.

[0079] S534, pre-burning the batch of raw materials at the temperature.

[0080] S535, returning the selection of a batch of sheeted raw materials and the selection of a pre-sintering temperature. A batch of sheeted raw materials corresponds to a pre-sintering temperature.

[0081] Pre-sintering is one of the key steps in the powder sintering process. It achieves a series of physical and chemical reactions by heat treating the compact at a temperature lower than the final sintering temperature.

[0082] First, pre-sintering can effectively remove volatile impurities in the powder, such as moisture, gas, and chemically bound water. If these impurities are removed during the final sintering process, they may cause cracks or deformation in the product. Through pre-treatment, these problems can be solved in advance, thereby improving the reliability and consistency of the product.

[0083] Secondly, the powder will undergo initial densification during the pre-sintering process. At this stage, the contact area between particles increases, sintering necks begin to form, and the powder body gradually becomes stronger. This not only improves the mechanical strength of the material, but also provides a better foundation for subsequent high-temperature treatment.

[0084] Furthermore, pre-sintering can adjust the grain structure and promote the transformation of crystal shape. This structural adjustment is conducive to optimizing the performance of the material, such as improving hardness, wear resistance and corrosion resistance. In particular, in some special applications, such as parts used in high temperature or high pressure environments, this role of pre-sintering is particularly critical.

[0085] Finally, pre-firing helps control the dimensional accuracy of the product. During the final sintering process, if large-scale material migration and structural reorganization occur, it may cause unpredictable shrinkage or expansion, thus affecting the dimensional accuracy of the product. By pre-performing partial densification and structural adjustment in the pre-firing stage, these changes can be effectively controlled to ensure that the final product meets the design requirements.

[0086] In one embodiment of the present application, S600 includes:

[0087] S611, select a raw material after black vibration.

[0088] S612, adding pure water and a binder to the raw material based on the quality of the raw material.

[0089] S613, performing sand grinding and stirring.

[0090] Specifically, the mixing process allows different types of powder to be fully mixed to achieve overall compositional uniformity. This helps to form a uniform microstructure during the sintering process and avoid compositional segregation. Compositional segregation can lead to inconsistent material properties and affect the reliability and durability of the finished product.

[0091] More specifically, sand milling can also change the crystal structure of the raw materials.

[0092] S614: Based on the particle size of the raw material, determine whether the particle size of the raw material is less than or equal to the particle size threshold of the initial recipe.

[0093] S615, if the particle size of the raw material is greater than the particle size threshold of the initial formula, return to the sand grinding and stirring step.

[0094] S616: If the particle size of the raw material is less than or equal to the particle size threshold of the initial formula, the sand grinding and stirring is stopped.

[0095] S617, returning to the process of selecting a raw material after black vibration until all raw materials after black vibration are selected.

[0096] S621, select a raw material after sand grinding and mixing.

[0097] S622, spraying is performed on the raw material after sand grinding and stirring.

[0098] S623, determining whether the moisture content of the raw material after spraying is equal to or greater than the moisture content threshold of the initial formula.

[0099] S624, if the water content of the raw material after spraying is less than the water content threshold of the initial formula, return to the step of spraying the raw material after sand grinding and stirring.

[0100] S625, if the moisture content of the raw material after spraying is equal to or greater than the moisture content threshold of the initial formula, determine whether the loose specific gravity of the raw material after spraying is consistent with the loose specific gravity of the initial formula.

[0101] S626, if the loose specific gravity of the raw material after spraying does not match the loose specific gravity of the initial formula, adjust the compactness of the raw material after spraying, and return to the step of judging whether the loose specific gravity of the raw material after spraying matches the loose specific gravity of the initial formula.

[0102] S627, if the loose specific gravity of the raw material after spraying is consistent with the loose specific gravity of the initial formula, the spraying operation is terminated.

[0103] Specifically, the mixing process improves the fluidity and plasticity of the powder, which is crucial for the subsequent forming process. Good fluidity allows the powder to evenly fill the mold and reduce defects during forming. The improved plasticity ensures that the compact can be stably formed under pressure. Together, these properties improve the quality and consistency of the green body before sintering.

[0104] More specifically, in actual ferrite production, raw materials with good chemical composition may not always produce ferrites with good performance and microstructure, and the reason is the influence of physical properties. The physical properties of iron oxide listed in Table 1 include average particle size APS, specific surface area SSA and bulk density BD. Since iron oxide accounts for about 70% of the manganese-zinc ferrite formula, its APS value has a great influence on the APS value of ferrite powder. Generally speaking, the smaller the APS value of iron oxide, the smaller the APS value of ferrite powder, which is conducive to accelerating the speed of chemical reaction. However, considering that the powder particles are too fine, which is not conducive to the subsequent pressing and the easy crystallization during sintering, the APS value should not be too small. Obviously, when the APS value of iron oxide is too large, during pre-sintering, due to the large particle size, only the diffusion reaction of the spinel phase can be carried out, and the grain growth process cannot be further carried out. This will inevitably lead to an increase in the activation energy required for sintering, which is not conducive to solid-phase reaction.

[0105] Secondly, generally speaking, fine iron oxide powder means large specific surface area (SSA) value and good reaction activity. Under certain process conditions, it is easy to obtain excellent ferrite. However, too fine powder is easy to agglomerate, which brings difficulties to the uniformity of mixing. Moreover, fine powder is very easy to cause self-sintering during the sintering process, forming large single-component agglomerates, resulting in deterioration of ferrite performance. The self-sintering of nano-raw materials seriously affects its application in the manganese-zinc soft ferrite industry. For spherical particles, the larger the SSA value, the smaller the APS value. But for irregularly shaped particles, this is not necessarily the case.

[0106] The bulk density BD is a comprehensive parameter. Generally, the smaller the APS value and the larger the SSA value, the smaller the BD. This is because the friction between particles increases. At the same time, BD also reflects the shape of the particles. The more irregular the particle shape and the lower the sphericity, the smaller the BD. Spherical particles have better activity than rod-shaped particles.

[0107] S631, selecting a raw material after a pre-fired batch.

[0108] S632, heating and sintering the raw materials.

[0109] S633, vibrating the sintered raw material; the heating and sintering and the vibration together constitute a black vibration operation.

[0110] S634, returning to the process of selecting a pre-burned batch of raw materials until all raw materials are selected.

[0111] Specifically, the sintering temperature of manganese-zinc ferrite is usually controlled between 1200 and 1400°C. This temperature range is conducive to promoting grain growth and densification, while avoiding excessive grain growth and structural deterioration caused by excessive temperature. Holding time is also an important factor affecting the pre-sintering effect. Appropriate holding time can ensure that the internal reaction of the material is fully carried out, thereby obtaining the ideal microstructure and magnetic properties. Studies have pointed out that too short a holding time may lead to insufficient reaction, while too long a holding time may lead to excessive grain growth.

[0112] The present application provides a debugging system for a magnetic storage device.

[0113] like Figure 2 As shown, in one embodiment of the present application, a debugging system for a magnetic storage device includes an industrial computer 100, a vibrator 200, an analysis instrument 300, a rolling machine 400, an electric furnace 500 and a stirrer 600.

[0120] This embodiment relates to a debugging system for a magnetic storage device.

The analytical instrument 300 performs quality control detection on each selected raw material. By using the method of controlling a single variable, the raw material detected by the analytical instrument 300 is included in all the raw materials of the test formula.

The full-cycle monitoring and adjustment of the parameters of the material sintering process of the selected raw materials is conducive to controlling the influence of the raw materials on the initial formula of theoretical calculation, and then achieving the yield rate of the material characteristics of high pressure resistance after the magnetic storage device is fired.
