Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of ultrafine crystal strips, in particular to a multi-stage heat treatment device for producing ultrafine crystal strips. Background Art

[0002] Ultrafine crystal strip is an ultrathin magnetic material with a thickness of less than 1mm, mainly composed of magnetic metal and alloy products; heat treatment of ultrafine crystal strip can enhance the performance and stability of the material; generally speaking, heat treatment can effectively improve the electrical conductivity and mechanical strength of the material, and can also enhance the wear resistance and corrosion resistance of the material. During the heat treatment process, the ultrafine crystal strip needs to be heated to a certain temperature and maintained for a period of time to achieve material homogenization and grain refinement. This process can be controlled by controlling parameters such as heating speed, holding time and cooling speed. During the cooling process, water quenching, oil quenching or air cooling can be used to obtain different structures and properties. It should be noted that deformation and cracking may occur during the heat treatment process.

[0003] Therefore, in the prior art, a multi-stage heat treatment device is used to complete the stable treatment of the ultrafine crystal strip. However, when the ultrafine crystal strip is fed into the heat treatment box, the linear feeding path will cause the contact between the heating element and the ultrafine crystal strip to be insufficient, that is, the heat treatment range is too small to affect the progress, and the continuous circumferential feeding path will cause the front and back sides of the strip to not receive the same temperature treatment, resulting in uneven heating during the heat treatment of the ultrafine crystal strip.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-stage heat treatment device for the production of ultrafine crystal strips, so as to solve the problems that the heat treatment range of ultrafine crystal strips is too small due to the use of a linear feed path during the heat treatment process and the front and back sides of the strip cannot receive the same temperature treatment due to the use of a continuous circular feed path.

[0008] Preferably, a plug rod is installed at the rear end of the transmission roller, the plug rod matches the plug hole, a threaded ring sleeve is installed on the external thread of the plug rod, and the threaded ring sleeve is also threadedly connected with the positioning ring.

[0009] Preferably, locking bolts are installed on the outer sides of the strips wound around the pre-processing box, the full-processing box and the post-processing box respectively, and the locking bolts are rotatably connected to the pre-processing box, the full-processing box and the post-processing box. A swing rod is installed on the outer end of the locking bolt, and the electromagnetic heating rods are evenly distributed to the outer side of the swing rod and are parallel to the strip to be processed in the vertical direction.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] This embodiment is used to solve the problem that the heat treatment range of ultrafine crystal strip is too small due to the use of a linear feeding path and the front and back sides of the strip cannot be treated at the same temperature due to the use of a continuous circumferential feeding path during the heat treatment process. The details are as follows:

[0026] See also Figure 1 - Figure 6As shown, this embodiment is a multi-stage heat treatment device for ultrafine crystal ribbon production, including a pre-treatment box 2, a full-treatment box 3 and a post-treatment box 4, the pre-treatment box 2, the full-treatment box 3 and the post-treatment box 4 are arranged in sequence, and the lower ends of the pre-treatment box 2 and the post-treatment box 4 are aligned with the upper end of the full-treatment box 3, and the pre-treatment box 2, the full-treatment box 3 and the post-treatment box 4 are installed with heat treatment mechanisms inside, and the heat treatment mechanisms include transmission rollers 6 and electromagnetic heating rods 8, and the transmission rollers 6 are respectively arranged at the middle of the upper ends of the pre-treatment box 2 and the post-treatment box 4 and the middle of the lower end of the full-treatment box 3, and the strip to be treated is inserted into the pre-treatment box 2, the full-treatment box 3 and the post-treatment box 4 and is wound around the transmission rollers 6;

[0027] The inner bottom end of the transmission roller 6 corresponding to the pre-processing box 2, the full-processing box 3 and the post-processing box 4 is installed with a mounting ring 9, a plurality of plug holes 10 are opened in the mounting ring 9, and a positioning ring 11 is installed at the outer end of the mounting ring 9 corresponding to the plug hole 10, and the rear end of the transmission roller 6 is installed with an insertion rod 12, the insertion rod 12 matches the plug hole 10, and the external thread of the insertion rod 12 is installed with a threaded ring sleeve 13, and the threaded ring sleeve 13 is also threadedly connected with the positioning ring 11;

[0028] The outer side of the strips wound around the pre-treatment box 2, the full-treatment box 3 and the post-treatment box 4 is provided with a locking bolt 14, which is rotatably connected with the pre-treatment box 2, the full-treatment box 3 and the post-treatment box 4, and the outer end of the locking bolt 14 is provided with a swing rod 7, and the electromagnetic heating rod 8 is evenly distributed to the outer side of the swing rod 7 and is parallel to the strip to be treated in the vertical direction, that is, the electromagnetic heating rod 8 and the ultrafine grain strip to be treated do not contact each other but can provide a stable heat source, and the adjustable heat source setting, a certain position of the ultrafine grain strip is continuously heated or cooled in stages during the heat treatment process, so that the front and back sides of the strip are treated at the same temperature;

[0029] The lower ends of the pre-treatment box 2 and the post-treatment box 4 and both sides of the upper end of the full-treatment box 3 are respectively provided with perforation one 15 and perforation two 16. The strip passes through the perforation one 15 and extends into the perforation two 16. The rear sides of the pre-treatment box 2, the full-treatment box 3 and the post-treatment box 4 are jointly installed with a substrate 1. Guide rollers 5 are installed on the outer sides of the substrate 1 corresponding to the perforation one 15 and the perforation two 16. The strip is continuously wound through the guide rollers 5 and the transmission rollers 6. The above-mentioned structural distribution design is to ensure that during the feeding process of the ultrafine crystal strip during the heat treatment, the pre-treatment box 2 first completes the heat treatment of the surface of one side, and then enters the full-treatment box 3 to complete the heat treatment of the surface of the other side, and finally enters the post-treatment box 4 to complete the comprehensive heat treatment process.

[0030] The working principle of the utility model is as follows:

[0031] See also Figure 2 As shown, when the ultrafine crystal strip is heat treated, the strip to be treated is first introduced into the pre-treatment box 2 through the guide roller 5 ( Figure 2When the strip to be processed enters and exits the pre-processing box 2, there is also a group of guide rollers 5 (not shown in the figure), which play a guiding role when the strip to be processed passes through the perforation 15 and the perforation 2 16), so that the strip is wound onto the transmission roller 6, and the strip continues to pass through the perforation 15 and the perforation 2 16 to enter the full processing box 3. The strip once again bypasses the transmission roller 6 and continues to be wound by the transmission roller 6. When it is discharged from the perforation 15 on the full processing box 3, it enters the post-processing box 4 through the perforation 2 16 again, and is wound onto the transmission roller 6. Finally, it is received by the guide roller 5 and forms a heat-treated strip.

[0032] It should be noted that: during the heat treatment of the ultrafine crystal strip, in order to make the same side of the strip undergo heat treatment at different temperatures, the pre-treatment box 2, the full treatment box 3 and the post-treatment box 4 are arranged in a continuous manner, so that the ultrafine crystal strip passes through the pre-treatment box 2 to complete the heat treatment on one side, then passes through the full treatment box 3 to complete the heat treatment on the other side, and finally the post-treatment box 4 completes the heat treatment on the first side, thereby achieving the purpose of comprehensive heat treatment and enabling the metal strip to achieve a continuous heat treatment process;

[0033] At the same time, refer to Figure 3 , Figure 4 and Figure 6 After the swing rod 7 is rotated through the locking bolt 14, the distance between the electromagnetic heating rod 8 on the swing rod 7 and the ultra-fine crystal strip being fed is changed, and the winding position of the strip can also be changed by changing the position of the transmission roller 6 in the mounting ring 9, specifically as follows: first, the threaded ring sleeve 13 is separated from the positioning ring 11, and then the insertion rod 12 is inserted into a different insertion hole 10, and then the threaded ring sleeve 13 is used to complete the socket connection with the positioning ring 11 corresponding to the insertion hole 10, so as to fix the transmission roller 6, and at this time, the transmission roller 6 is aligned with the inner walls on both sides. The distance between them changes, combined with the above, by rotating the position of the electromagnetic heating rod 8 through the locking bolt 14 (the locking bolt 14 and the heat treatment box are bolted and connected, and can rotate 360° to form a rotation of the swing rod 7 to complete the locking, which will not be elaborated here), thereby achieving a change in the distance between the electromagnetic heating rod 8 and the ultrafine crystal strip being fed, that is, the non-parallel setting can change a certain position of the ultrafine crystal strip to obtain continuous graded heating or cooling during the heat treatment process, so that the front and back sides of the strip receive the same temperature treatment.

[0034] In summary: the multi-stage heat treatment device can realize continuous multi-stage heat treatment of ultrafine crystal strips in the production process, and is arranged in a swinging heating manner combined with an adjustable strip heating contact area. Its purpose is to enable the ultrafine crystal strip to receive different temperature treatments during the heat treatment process at a certain position, thereby improving the comprehensiveness of the entire strip during the heat treatment process.

[0035] The above contents are merely examples and explanations of the structure of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
