Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe processing, in particular to a solid solution furnace for ship thick-walled pipe production. BACKGROUND

[0002] In the field of shipbuilding, thick-walled pipes are widely used in the power system, piping system and special equipment of ships because they need to withstand high pressure, corrosive media and complex structural stress. In order to ensure that they have sufficient strength, toughness and long-term corrosion resistance in harsh marine environments, such pipes usually need to be subjected to solid solution heat treatment during production. The solid solution furnace is a key equipment for implementing this heat treatment process. Its role is to heat the pipe material to a specific high temperature and keep it at that temperature, so that the alloy elements are fully dissolved in the matrix. Then, through rapid cooling (quenching), the material is fixed in a supersaturated solid solution state, thereby improving the mechanical properties and corrosion resistance of the material, laying the foundation for subsequent processing and safe service. Currently, the industry generally uses a heating furnace body for solid solution treatment and then transfers it to a cooling pool for quenching.

[0003] The present application provides a solid solution furnace for ship thick-walled pipe production to solve the above problems. Most existing solid solution furnaces use static placement of pipes for heating. Due to the influence of the weight of the pipes and the support contact surface, heat conduction is uneven, which can easily cause local overheating or underheating of the pipes, thereby affecting the solid solution effect of the alloy elements. Traditional bearing structures are mostly fixed or simple block supports that are resistant to fire. They are difficult to quickly adapt to thick-walled pipes of different diameters, and need to be manually adjusted or replaced with tooling when changing product specifications, which is inefficient. In addition, the process of removing high-temperature pipes from the furnace and transferring them to the cooling pool relies on the operation of cranes or manual pushing, which is slow and results in large heat loss. High-temperature lifting poses a safety risk, resulting in a large amount of heat loss from the furnace and high energy consumption.

[0028] In this embodiment, a drive roller 762 is rotatably connected to the top of the heat-resistant block 761. A first linkage sprocket 763 is coaxially connected to one side of the drive roller 762. A second linkage sprocket 765 is coaxially fixedly connected to one side of the mating sprocket 766. A connecting chain 764 is meshed with the outer periphery of the first linkage sprocket 763 and the second linkage sprocket 765. Both the first linkage sprocket 763 and the connecting chain 764 are rotatably connected inside the heat-resistant block 761. Among them, the heat-resistant block 761 and the drive roller 762 are both made of heat-insulating and fire-resistant materials, which can protect the internal linkage sprocket 1 763, connecting chain 764, linkage sprocket 2 765 and docking sprocket 766. When the bottom of the docking sprocket 766 meshes with the drive chain 63, the drive roller 762 will rotate, thereby driving the thick steel pipe to rotate.

[0029] In this embodiment, a track 14 is provided on the inner side of the furnace body 11. The track 14 is installed on the ground and cooperates with the trolley 61. The bottom of the trolley 61 has a drive unit that can drive the wheels of the trolley 61 to rotate, and the wheels cooperate with the track 14.

[0030] In this embodiment, a lifting mechanism 3 is provided on the outside of the pool mechanism 2. The lifting mechanism 3 is installed on the ground, and the pool mechanism 2 is partially buried in the ground. The upper end of the pool mechanism 2 is flush with the chassis of the trolley 61. The lifting mechanism 3 consists of a lifting device and a supporting mesh plate. The lifting device can drive the mesh plate to move up and down. The mesh plate is located inside the water tank mechanism 2 and is used to support the heated thick steel pipe.

[0031] The working principle of this invention is as follows: When solution treatment is required for marine thick steel pipes, each bearing mechanism 7 can be hoisted and placed above the trolley mechanism 6. Then, the trolley mechanism 6 can be pushed to move into the furnace body 11 and the gate 13 can be closed, so that the thick steel pipe can be heated to the solution temperature. After holding at the temperature for a period of time, the gate 13 is opened and the trolley mechanism 6 is moved out. Then, the electric hydraulic cylinder 56 is operated by the external control equipment, so that one side of multiple bearing mechanisms 7 is rotated upward by ten degrees, thereby allowing the thick steel pipe to roll into the water tank mechanism 2 for quenching and cooling, thereby improving the strength, hardness and corrosion resistance of the material. Before hoisting the thick steel pipe above the multiple supporting mechanisms 7, the distance between the fixed component 75 and the linkage component 76 can be adjusted to accommodate different pipe diameters. After adjustment, multiple refractory blocks 77 can be inserted into the empty space of the adjustment groove 72 to avoid damaging the drive chain 63 inside the groove 62 during heating. In addition, when the linkage component 76 is installed, the docking sprocket 766 at the bottom of the heat-resistant block 761 will contact the outer periphery of the drive chain 63. Therefore, after the trolley mechanism 6 and the supporting mechanism 7 carry the thick steel pipe into the interior of the furnace body 11, the drive motor 64 can be operated by the external control device to make the drive chain 63 rotate, thereby driving the drive roller 762 to rotate. Since the drive roller 762 contacts the outer periphery of the thick steel pipe, it can drive the thick steel pipe to rotate. Thus, in the initial stage of heating the thick steel pipe in the furnace body 11, the thick steel pipe can rotate above the supporting mechanism 7, thereby heating more evenly. When the thick steel pipe is heated and the trolley mechanism 6 has completely moved out of the furnace body 11, one end of the trolley 61 will just contact the sliding seat 55 and drive the sliding seat 55 to move together. Then, the insulation door plate 42 can slide on the bottom of the inclined guide rail 41 and cover the port of the furnace body 11 through the steel cable 54. Thus, after the trolley mechanism 6 has completely moved out of the furnace body 11, the insulation door plate 42 is forced to block the port of the furnace body 11, thereby preventing heat loss and reducing heat loss. After the trolley 61 is completely moved out of the furnace body 11, the roller 67 on one side will be above the pallet 57. At this time, the electric hydraulic cylinder 56 is operated by the external control equipment, which can raise the lifting plate 65 and drive one end of all the support frames 71 to tilt upward. Thus, after the trolley 61 is completely moved out of the furnace body 11, the thick steel pipe can be introduced into the interior of the water tank mechanism 2 for cooling treatment without the need for crane transfer. After the cooling is completed, the thick steel pipe can be taken out by the lifting mechanism 3.
