Description

Technical Field

[0001] The present invention relates to the technical field of smelting and pouring equipment, and more specifically, to a ferroalloy product smelting and pouring machine and a pouring method. Background Art

[0002] Ferroalloy product smelting and pouring machine is a device specially used for smelting and pouring ferroalloy products. It injects ferroalloy liquid into the mold through a ladle filled with ferroalloy liquid. PLC will accurately control the pouring speed and pouring amount to achieve automatic pouring. It is widely used in the foundry industry, especially for mass production of ferroalloy products, such as automotive parts, mechanical parts and other manufacturing fields;

[0003] At present, it is found in actual smelting and pouring operations that when the ferroalloy liquid enters the ladle, it is necessary to ensure that the internal surface of the ladle is smooth. The impurities generated during the pouring operation require workers to use special rakes to thoroughly scrape the slag in the ladle to ensure that there is no residue. This process will undoubtedly take up a lot of time, and the quality of manual cleaning is difficult to guarantee. Once some impurities remain, the ferroalloy liquid will surge when entering, and the external air will be drawn into the interior, eventually causing bubbles to appear inside the product, affecting the production quality of ferroalloy products.

[0004] In order to solve the above problems, the present application proposes a ferroalloy product smelting pouring machine and a pouring method. Summary of the invention

[0005] The purpose of the present invention is to provide a ferroalloy product smelting pouring machine and a pouring method, which solves the problems of inconvenient ladle cleaning and too fast heat loss of ferroalloy liquid.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A ferroalloy product smelting and pouring machine, characterized in that the pouring machine comprises:

[0008] The ladle and its outer fixing frame are located above the lifting seat in front of the pouring machine;

[0009] A protective plate is located inside the ladle and adjacent to the surface of the ferroalloy liquid, and is used to limit the surging of the ferroalloy liquid when the pouring machine moves. A driving motor is provided above the front end of the fixed frame to drive the protective plate to move up and down;

[0010] The outer ring frame is located outside the protective plate, and an outer scraper is provided below it, which is used to remove impurities on the inner surface of the ladle and perform residual detection before the ferroalloy liquid enters. A micro drive unit is provided on the upper left side of the protective plate to drive the outer ring frame to rotate;

[0011] The lower scraper is located below the protective plate and is used to remove impurities from the bottom surface of the ladle and perform residual detection before the ferroalloy liquid enters. A rotating motor is provided above the central area of ​​the protective plate to drive the lower scraper to rotate;

[0012] The slide is symmetrically distributed inside the protective plate and is received in the limit groove. A heat storage unit is provided above the slide to delay the heat loss of the ladle and the ferroalloy liquid.

[0013] On the other hand, the present invention provides a pouring method of the pouring machine, the specific steps of which are as follows:

[0014] S1: Before the ferroalloy liquid is introduced into the ladle, the driving motor drives the support frame to descend, so that the outer scraper slides down along the inner wall of the ladle to form a surface smoothness test;

[0015] S2: When the protective plate moves to the bottom area of ​​the ladle, the rotary motor drives the lower scraper to rotate to detect the smoothness of the inner bottom surface;

[0016] S3: After passing the test, the ferroalloy liquid is introduced into the ladle, and the protective plate is lowered to the inside of the port of the pouring machine;

[0017] S4: While the ferroalloy liquid is stored in the ladle, the slide is lowered by the lifting unit so that the heat release unit is placed in an area near the ferroalloy liquid surface;

[0018] S5: Further, the heat storage unit is combined with the heat release unit to release heat, and the internal materials of the ladle and the ferroalloy liquid are simultaneously kept warm to delay the loss of heat;

[0019] S6: When the pouring machine needs to be transferred to pour into a mold at another location, the bottom plate is retracted to the limit groove, and the bottom surface is flush with the bottom surface of the protective plate to protect the ferroalloy liquid and avoid large surges during the movement of the equipment;

[0020] S7: Finally, after the pouring operation is completed, the outer scraper and the lower scraper are rotated by the micro drive unit and the rotary motor to scrape off the residual liquid in the ladle before it completely solidifies and pour it to the outside. At the same time, the heating function is combined to continuously soften the impurities for easy cleaning.

[0021] Beneficial effects of the present invention:

[0022] The present invention can detect the ladle before the ferroalloy liquid enters by adding an outer ring frame and a lower scraper. By utilizing the downward probe and the rotation of the lower scraper, impurities and dirt in the ladle can be found according to its operating status, so as to discover problems in time, effectively prevent the ferroalloy liquid from being drawn in when entering, reduce the bubble productivity of ferroalloy production, and facilitate control of quality during mass production operations.

[0023] The present invention can further downwardly probe and rotate immediately after the pouring operation by adding the outer ring frame and the lower scraper, so that the impurities on the inner wall surface of the ladle are scraped off in a short time, and at the same time, the raised parts are subjected to a certain grinding treatment to ensure that the inner wall of the ladle is smooth. At this time, the impurities have not yet completely solidified, and the cleaning is simple and quick. The ladle can be put into use for the next group of pouring operations without the need for manual removal.

[0024] After the ferroalloy liquid enters, the present invention lowers the slide to the area adjacent to the liquid surface of the ferroalloy liquid, and while heat release is used to insulate the ladle, the heat loss rate of the ferroalloy liquid is slowed down, so that the pouring operation of the ferroalloy liquid does not need to be carried out in a hurry, thereby reducing the difficulty of the pouring operation, and at the same time improving the safety of the pouring operation, which is convenient for mold replacement during batch pouring operations;

[0025] The present invention can limit the shaking of the ferroalloy liquid through the bottom of the protective plate when the equipment moves, reduce its fluctuation amplitude, prevent the ferroalloy liquid from splashing, ensure the safety of the casting operation and reduce the air content.

[0040] The slide 230 is distributed between the left and right limit grooves 202 of the protection plate 200, and a heat storage unit 231 is installed on the upper part and a heat release unit 233 is installed on the lower part to delay the heat loss of the ladle 110 and the ferroalloy liquid;

[0041] Both front and rear ends of adjacent slides 230 are provided with connecting plates 214 to connect with each other, and a seat lifting unit 213 is installed above the connecting plates to connect with the supporting plate mechanism at the bottom of the supporting frame 210 .

[0042] In the specific implementation, first, the driving motor drives the outer ring frame 220 and the lower scraper 240 to move downward through the protective plate 200, and the lower scraper 240 is rotated at the bottom of the ladle 110. During this movement, the movement status of the outer ring frame 220 and the lower scraper 240 is recorded, so as to achieve the effect of detecting whether there are residual impurities in the ladle 110; after the detection is qualified, it is removed for the introduction of ferroalloy liquid, and then the protective plate 200 is lowered to be placed in the area adjacent to the surface of the ferroalloy liquid. At this time, the upper end of the inclined surface of the outer scraper 222 is at the same height as the bottom surface of the protective plate 200. After this arrangement, it can form a seal and insulation, and can also form protection for the ferroalloy liquid to ensure that it does not produce large-scale shaking and splashing when the equipment moves; further, the heat release unit 233 is driven by the lifting unit 213 through the slide 230 to move to the adjacent ferroalloy liquid area, and then the heat is released to heat the ferroalloy liquid and the internal materials of the ladle 110 at the same time, forming a thermal insulation effect to extend the storage time of the ferroalloy liquid for the convenience of casting operations.

[0043] like Figure 1 and Figure 2 As shown, the fixing frame 120 is a "U"-shaped structure with an opening at the bottom, and a slideway 121 is provided inside the front and rear support rods, and a screw 122 is installed inside the drive motor connected to the front end of the fixing frame 120. The rod body mechanism located inside the rear slideway 121 is a smooth slide rod.

[0044] like Figure 1 and Figure 2 As shown, the front and rear ends of the support frame 210 above the protective plate 200 are both installed with spiral sleeves 211 through baffles 212. The baffles 212 are also used to resist the front and rear inner sides of the fixing frame 120, and balls are arranged inside to ensure the synchronization of the sliding movements at both ends.

[0045] like Figure 1 , Figure 4 and Figure 6 As shown, the outer ring area of ​​the protective plate 200 is installed with a rotating seat 223 through a slide groove 225, and an electric telescope is installed above it to connect with the inner end surface of the groove of the outer ring frame 220. While maintaining the rotation function of the outer ring frame 220, it can be raised and lowered at any time to align the bottom surface with the protective plate 200.

[0046] like Figure 4 and Figure 6 As shown, a bottom plate 232 for mounting a heat release unit is provided below the slide 230 , and when the heat release unit 233 is not in use, it is stored inside the limiting groove 202 for protection.

[0047] like Figure 3 and Figure 6As shown, adjacent limiting grooves 202 separate the protective plate 200, forming a horizontal frame for installing the rotating motor in the middle area, and the lower scraper 240 is stored under the horizontal frame after use to leave space for the heat release unit 233 to be lowered.

[0048] Embodiment 2

[0049] See also Figure 1 - Figure 6 As shown, the present invention provides a casting method of the casting machine 1, and the specific steps are as follows:

[0050] S1: Before the ferroalloy liquid is introduced into the ladle 110, the support frame 210 is driven downward by the driving motor so that the outer scraper 222 slides down along the inner wall of the ladle 110 to form a surface smoothness test;

[0051] S2: When the protective plate 200 moves to the bottom area of ​​the ladle 110, the lower scraper 240 is driven by the rotary motor to rotate to form a smoothness test on the inner bottom surface of 1;

[0052] S3: After the test is qualified, the ferroalloy liquid is introduced into the ladle 110, and the protection plate 200 is lowered to the inside of the port of the pouring machine 100;

[0053] S4: While the ferroalloy liquid is stored in the ladle 110, the lifting unit 213 lowers the slide 230 so that the heat release unit 233 is placed in an area near the ferroalloy liquid surface;

[0054] S5: Further, the heat storage unit 231 releases heat in combination with the heat release unit 233, and simultaneously performs heat preservation treatment on the internal materials of the ladle 110 and the ferroalloy liquid to delay the loss of heat;

[0055] S6: When the pouring machine 100 needs to be transferred to pour into a mold at another location, the bottom plate 232 is retracted to the limiting groove 202, and the bottom surface is flush with the bottom surface of the protection plate 200 to protect the ferroalloy liquid and avoid large surges during the movement of the equipment;
