Abstract
Description
Technical Field
[0001] This utility model relates to the field of molten iron feeding wire balling technology, and in particular to an automatic transfer and casting device for molten iron feeding wire balling. Background Technology
[0002] Wire feeding spheroidizing is a spheroidizing treatment process in ductile iron production. After the molten iron is tapped from the furnace, a cored wire (the core material is generally magnesium, rare earth elements, or other spheroidizing elements) is continuously and stably fed into the molten iron in the ladle via a wire feeder. Under the high temperature of the molten iron, the cored wire melts and reacts chemically with the molten iron, causing the graphite in the molten iron to precipitate in a spheroidal form. This process allows for precise control of the amount of spheroidizing elements added, improving the spheroidizing effect and casting quality, and reducing the loss of spheroidizing agents.
[0003] In the spheroidization process using molten iron wire feeding, the transfer of the casting ladle from the furnace outlet to the wire feeder is a crucial step. Once the molten iron reaches the required temperature and composition in the furnace, the operator uses a crane to smoothly lift the empty ladle to below the furnace outlet using a specialized lifting device. Then, the outlet valve is slowly opened, allowing the molten iron to flow precisely into the ladle. After the appropriate amount of molten iron has been filled, the valve is quickly closed, and the ladle, now full of molten iron, is transferred again by a transfer cart to a designated location next to the wire feeder, preparing for the subsequent spheroidization process.
[0004] The shortcomings of the existing technical solutions are as follows: When pouring molten iron, the molten iron flows steadily into the transfer ladle at a suitable flow rate. This process is affected by factors such as the viscosity of the molten iron and flow control, and takes a long time. After the ladle reaches the wire feeder, it is then driven into the wire feeding machine for a lengthy wire feeding operation. After the wire feeding is completed, the ladle is returned and transported to the working area of the casting robot arm. Although the entire pouring, transfer, and wire feeding process is continuous, its distribution and equipment are only designed for one ladle. The cumulative time spent in each step results in low overall efficiency of the existing transfer equipment. Utility Model Content

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.
[0025] like Figures 1 to 3 As shown in the figure, this utility model provides an automatic transfer and casting device for molten iron feeding and balling, including a transfer cart 1 for transferring casting ladles from the output port of the corresponding smelting furnace 2 to the input port of the corresponding wire feeder 3. Both the smelting furnace 2 and the wire feeder 3 are provided with two or more sets, and the number is the same. The transfer cart 1 is equipped with at least two sets of first transfer roller conveyors 101. The first transfer roller conveyor 101 is driven by a motor to the first roller, and subsequent rollers have gears at their ends, transmitting power step by step via chains to realize the transportation of casting ladles. The number of first transfer roller conveyors 101 is not less than the number of smelting furnaces 2, enabling one transfer cart 1 to transport multiple sets of casting ladles to the corresponding wire feeder 3 positions at one time, saving transportation time and investment costs. The bottom of the transfer cart 1 is equipped with a drive assembly, which drives it to transport the casting ladles from the output port of the smelting furnace 2 to the output port of the wire feeder 3.
[0026] Each wire feeder 3 has a channel running through its lower end, containing a third transfer roller conveyor 302 for transporting the casting ladle. The casting ladle enters the working area of the wire feeder 3 via the third transfer roller conveyor 302 for wire feeding. After completion, it does not need to be returned and transported to the casting machine working area, but directly enters the casting area via the third transfer roller conveyor 302. The casting robotic arm then holds the casting ladle for casting operations, saving time on return trips.
[0027] In one specific embodiment, such as Figure 1 As shown, the first transfer roller conveyor 101 has two sets, arranged parallel to each other on both sides above the transfer car 1. The smelting furnace 2 and the wire feeder 3 each have two sets. The two sets of smelting furnace 2 are located on both sides of one end of the slide rail 105, and the two sets of wire feeders 3 are located on both sides of the other end of the slide rail 105. The two sets of smelting furnace 2 can be filled with liquid simultaneously and transported by the transfer car 1, moving the two sets of casting ladles from near the smelting furnace 2 to the corresponding third transfer roller conveyor 302.
[0028] The drive assembly includes a slide rail 105 laid on the ground and a drive chassis 106 located at the bottom of the transfer vehicle 1 and engaging with the slide rail 105. The drive chassis 106 features a box-beam structure at its bottom to enhance bending resistance and meet support requirements. It is configured with a dual-axle four-wheel or four-axle eight-wheel layout, with wheel sets made of ZG55 cast steel or heat-resistant alloy wheels. Heavy-duty bearings combined with a variable frequency motor drive ensure smooth movement under heavy loads. It is equipped with six hydraulic outriggers that can automatically level and distribute 80% of the dynamic load to prevent track deformation. The drive chassis 106 integrates a load cell to monitor the load in real time.
[0029] The transfer car 1 is equipped with multiple sets of anti-splash ladle covers 102 located above the corresponding first transfer roller conveyors 101. These covers are used to cover the casting ladle during transport, reducing heat loss and preventing molten iron from splashing out and causing safety issues. The transfer car 1 is also equipped with multiple sets of position sensors 104, which are photoelectric sensors, located on one side of the corresponding first transfer roller conveyor 101. These sensors detect the position of the casting ladle. When the casting ladle reaches below the anti-splash ladle cover 102, the position sensor 104 reacts, and the controller stops the operation of the first transfer roller conveyor 101.
[0030] To prevent the ladle from tipping over due to the failure of the position sensor 104, each set of first transfer rollers 101 is equipped with an anti-tipping mechanism 103 at both ends. The anti-tipping mechanism 103 includes a drive assembly, a rotating shaft, and a baffle. The baffle is rectangular or elliptical. The drive assembly drives the baffle to rotate via the rotating shaft. When upright, the baffle blocks one end of the first transfer roller 101 to prevent the ladle from falling off. In conjunction with the emergency stop button, it ensures the stability of molten iron transportation. When there is a need to transport a ladle, the drive assembly drives the baffle to distribute laterally, allowing the ladle to be output from the end of the first transfer roller 101.
[0031] The output end of the smelting furnace 2 is equipped with a second transfer roller 201 for feeding the casting ladle into the corresponding first transfer roller 101. The lower end of the smelting furnace 2 is equipped with lifting baffles 301 on both sides of the channel to prevent splashing of molten iron during wire feeding. During wire feeding, the boiling point of magnesium is much lower than the temperature of molten iron. Magnesium vaporizes to form high-pressure steam bubbles that break through the surface layer of molten iron and cause splashing. The lifting baffles 301 can prevent molten iron from splashing out of the wire feeder 3.
[0032] Because the transfer car 1 is equipped with multiple sets of first transfer roller conveyors 101, it can transport multiple sets of casting ladles at once, eliminating the need for individual transfers and reducing transportation frequency and time. Simultaneously, the smelting furnace 2 and wire feeder 3 are rationally arranged, allowing the transfer car 1 to move quickly along the slide rail 105, shortening the transportation distance. Furthermore, after the casting ladle has been fed with wire, it does not need to return; it directly enters the casting area via the third transfer roller conveyor 302, reducing waiting time in intermediate steps. This shortens the overall iron feeding and balling process, improving production efficiency.
[0033] Working principle: In the smelting process, when the molten iron in the smelting furnace 2 reaches the required temperature and composition, it is poured into a ladle. The second transfer roller conveyor 201 at the output end of the smelting furnace 2 is activated, smoothly conveying the ladle into the first transfer roller conveyor 101 on the transfer car 1. At this time, the position sensor 104 on the transfer car 1 monitors the position of the ladle in real time. When the ladle reaches the designated position, that is, below the anti-splash ladle cover 102, the position sensor 104 sends a signal. After receiving the signal, the controller controls the first transfer roller conveyor 101 to stop running. At the same time, the anti-splash ladle cover 102 covers the ladle to reduce heat loss and prevent molten iron from splashing out.
[0034] Subsequently, the transfer vehicle 1 moves as a whole, transporting the casting ladles from the output position of the smelting furnace 2 to the corresponding output position of the wire feeder 3 along the slide rails 105 laid on the ground. Since the number of first transfer rollers 101 is no less than the number of smelting furnaces 2, one set of transfer vehicles 1 can transport multiple sets of casting ladles at one time, improving transportation efficiency.
[0035] Upon reaching the position of wire feeder 3, the third transfer roller conveyor 302 in the lower channel of wire feeder 3 is activated, transporting the casting ladle from the first transfer roller conveyor 101 to the working area of wire feeder 3. During the wire feeding process, the lifting baffles 301 on both sides of the lower channel of smelting furnace 2 rise to prevent splashing molten iron during wire feeding, ensuring operational safety. After wire feeding is completed, the casting ladle does not need to be returned and directly enters the casting area through the third transfer roller conveyor 302. At this time, the casting robotic arm fixes the casting ladle and performs the casting operation.
[0036] In addition, to prevent the pouring bag from being mistakenly output due to the failure of the position sensor 104, each set of first transfer roller conveyors 101 is equipped with an anti-tipping mechanism 103 at both ends. Under normal circumstances, the baffles are distributed horizontally and do not affect the conveying of the pouring bag; when an abnormal situation occurs, the drive component drives the baffle to rotate and stand upright, blocking one end of the first transfer roller conveyor 101 to prevent the pouring bag from falling off and to ensure the safe and reliable operation of the equipment.
[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
