[0026] The utility model provides the following technical solutions: Example 1
[0027] Combination Figures 1 to 5 A converter non-auxiliary gun assisted non-reversible furnace steel tapping device comprises a collecting box 1, a converter 3 and a collecting plate 5. A steel tapping pipe 2 is fixedly connected to the front of the converter 3, a covering mechanism 6 is fixedly connected to the inside of the collecting box 1, and an installation mechanism 4 is fixedly connected to the inside of the collecting box 1.

[0028] The covering mechanism 6 includes a first connecting block 62, which is fixedly connected to the lower front side of the collecting box 1, and a second connecting block 605 is fixedly connected to the upper front side of the collecting box 1.

Second slide grooves 604 are provided on both sides of the inside of the collecting box 1, and a second slider 607 is slidably connected to the inside of the second slide groove 604. A second baffle plate 606 is fixedly connected to the other side of block 607, and the front side of the second baffle plate 606 is fixedly connected to the back side of the fixed block 63. A first slide groove 602 is opened on the front side of the collecting box 1, and a first slider 601 is slidably connected inside the first slide groove 602. The front side of the first slider 601 is fixedly connected to the first baffle plate 68, and the left and right sides of the first baffle plate 68 are fixedly connected to the mounting block 603. An electric push rod 69 is fixedly connected to the front side of the collecting box 1, and the top of the electric push rod 69 is fixedly connected to the bottom of the mounting block 603.

[0029] Furthermore, a through hole is opened inside the first connecting block 62, and the surface of the worm 66 passes through the through hole opened inside the first connecting block 62. By setting up a covering mechanism 6, when the covering mechanism 6 is in operation, when collecting the fallen slag, with the cooperation of the covering mechanism 6, the fallen slag can be collected and accumulated on the collecting plate 5, so that the state of the fallen slag can be observed later. Example 2
[0030] See also Figure 1-6 On the basis of the first embodiment, the mounting mechanism 4 further comprises a T-slot 43, the T-slot 43 is provided on the left and right sides of the inner wall of the collection box 1, a T-plate 42 is slidably connected inside the T-slot 43, a pull plate 47 is fixedly connected on one side of the T-plate 42, a second T-slot 48 is provided inside the pull plate 47, the bottom of the second T-slot 48 is set as an opening, a second T-block 44 is slidably connected inside the second T-slot 48, a plug-in block 45 is fixedly connected to the side of the second T-block 44 close to the collection box 1, a long block 46 is fixedly connected to the front and back sides of the collection box 1, a square slot 41 is provided inside the long block 46, a side of the square slot 41 corresponding to the plug-in block 45 is set as an opening, and the inside of the square slot 41 and the surface of the plug-in block 45 are plugged in.
[0031] Furthermore, there are four T-slots 43 and four T-plates 42, and they are grouped in pairs. The two T-slots 43 and the two T-plates 42 are symmetrically arranged on the collecting box 1. By setting up the mounting mechanism 4, when the mounting mechanism 4 is in operation, when it is necessary to observe the state of the slag accumulated on the collecting plate 5, the collecting plate 5 can be conveniently taken away, which is quick and convenient.
[0032] Based on the carbon-oxygen product m=0.0025 at 1600℃, determine the carbon-oxygen product at different end temperatures, and then judge whether the bombing temperature measurement is accurate; do not lift the gun and bomb in advance 30 seconds after the carbon pulling starts, and judge whether to blow or cool down according to the test results of the TCO bomb meter. After exploration, the temperature can be increased by 1℃ and the carbon can be reduced by 0.005% per second in the later blowing;
[0033] The amount of slag to be retained is determined according to the Si level of the molten iron: when [Si]≤0.40%, all slag is retained; when 0.40%<[Si]≤0.60%, 1 / 3~1 / 2 of the slag is retained; when [Si]>0.60%, no slag is retained; no overoxidized slag is retained.
[0034] The slagging condition can be judged by the shape and fluidity of the slag falling from the furnace skirt plate during blowing. Flake slag indicates good slagging, while particles or metal splashing indicate poor slagging or slagging back to dryness. Adding it in the early and middle stages of blowing to increase the iron oxide content in the slag will help slagging and increase the water yield of the returned ore.
[0035] Deoxidation sequence: add iron blocks first when tapping 1 / 4 of the steel, then add ferrosilicon and silicon-manganese alloy, and finally strengthen the deoxidizer aluminum.
[0036] In actual operation, when this device is used, when collecting fallen slag, it is necessary to turn on the motor 61 and the electric push rod 69 switches in advance. When the electric push rod 69 is started, the electric push rod 69 can drive the mounting block 603, and the mounting block 603 drives the first baffle 68, and the first baffle 68 drives the first slider 601 to slide in the first slide groove 602. When the motor 61 is started, the motor 61 drives the worm 66 to rotate, and the worm 66 drives the turbine 67 to engage and connect in the original position. At this time, the turbine 67 drives the threaded rod 65 to rotate in the second connecting block 605. At this time, the connecting seat 64 can drive the fixed block 63 when moving on the threaded rod 65, and the fixed block 63 drives the second slider 607 to slide in the second slide groove 604. At the same time, the fixed block 63 drives the second baffle 606 to move, so that the three surfaces of the collection box 1 can be blocked to prevent the fallen slag from falling on the ground.
[0037] When it is necessary to remove the slag accumulated on the collecting plate 5 for observation at a later stage, the second T-block 44 is pushed to slide in the second T-slot 48, so that the second T-block 44 drives the insert block 45 to move out of the square slot 41, and then the T-plate 42 can be directly slid from the T-slot 43 to remove the collecting plate 5.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
