Technical Field

[0001] This utility model relates to the field of valve steel technology, specifically to an improved device for the annealing of martensitic valve steel discs. Background Technology

[0002] Valve steel is a key material for manufacturing intake and exhaust valves of internal combustion engines. It has the ability to serve for a long time in high temperature, high pressure and high corrosion environments. Wire rod is a long strip of steel with a circular cross section that is hot rolled or cold drawn. It is usually supplied in the form of coils and is widely used in the construction industry, metal products, industrial processing and other fields.

[0003] Annealing is a key heat treatment process in wire rod processing. It promotes the elimination of work hardening, reduces hardness, and improves plasticity to facilitate subsequent processing. Currently, some wire rods are tightly stacked in the annealing furnace with insufficient gaps, which affects heat transfer. The temperature difference between different coils in the furnace is large, affecting uniform heating and cooling effect. This can easily lead to poor coil shape after annealing, affecting the quality of subsequent processing and increasing production costs. Utility Model Content

[0026] refer to Figure 1 and Figure 4 As shown, the water pump 54 is internally connected to a delivery pipe 16, the first blower 51 is internally connected to an air supply pipe 17, one end of the air supply pipe 17 is connected to the interior of the refrigeration box 52, the refrigeration box 52 is internally equipped with a fan 18, and a storage box 19 is fixedly connected to one side of the refrigeration box 52.

[0027] Working Principle: In use, the inner rings of two coils are placed on the first support plate 41 through two fixing posts 42. The two coils are internally supported by the two sets of fixing posts 42, fixing rods 7, and support sleeves 8. The inner side of the second support plate 6 passes through the connecting post 43, and is supported and limited by the limiting block 44, leaving a gap between the first and second support plates 41 and 6. With the cooperation of the two sets of fixing posts 42, fixing rods 7, and support sleeves 8 on the second support plate 6, the two coils can be placed separately. The top plate 9 is threadedly connected to the top of the connecting post 43, allowing multiple coils to be arranged in layers with gaps between them, preventing stacking and facilitating heat transfer. Driven by the motor 14, the connecting rod 13 drives the second gear 12 to rotate, which in turn drives the first gear 11 to rotate the support base 10. The support base 10 drives the first support plate 41, the second support plate 6, and the multi-roll coil to rotate inside the annealing furnace 1, promoting uniform heating and improving the poor shape of the coil during annealing. When the coil needs to be cooled, the second fan 20 drives the heat in the annealing furnace 1 to be discharged outside the furnace. The water pump 54 drives the delivery pipe 16 to deliver the coolant in the storage box 19 to the circulation pipe 53 in the cooling box 52, so that the coolant circulates in the circulation pipe 53 and the storage box 19. The first fan 51 drives the air supply pipe 17 to deliver the cold air in the cooling box 52 to the connecting pipe 3. With the cooperation of the fan 18, the air flow and delivery in the cooling box 52 are accelerated, so that the connecting pipe 3 delivers the cold air to the annealing furnace 1. The rotation of the first support plate 41 and the second support plate 6 cools the coil evenly, reducing the poor shape caused by uneven cooling.
