Description

Technical Field

[0001] The utility model relates to the technical field of smelting, in particular to a flow tank car for improving the quality of low-micro-carbon ferrochrome finished products. Background Art

[0002] Conventional hot exchange pours liquid silicon-chromium alloy directly into the low-carbon ferrochrome furnace, which cannot effectively remove the waste slag in the liquid silicon-chromium, resulting in unstable quality of low-carbon ferrochrome products and a long reaction cycle. A launder with grate slag can be used for hot exchange. Since the liquid silicon-chromium alloy has a large specific gravity, it will preferentially flow into the low-carbon ferrochrome furnace from the bottom of the launder. The liquid silicon-chromium alloy waste slag has a light specific gravity and will be intercepted by the grate on the launder, thereby reducing the amount of waste slag entering the furnace. The waste after the grate needs to be dumped and discharged. Therefore, based on the above problems, a special launder car with a grate is designed. Utility Model Content

[0017] The present invention will be described below based on the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0018] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn according to scale.

[0019] At the same time, unless the context clearly requires otherwise, the words "include", "comprises" and similar words throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0020] See also Figure 1-Figure 6The utility model provides a technical solution: it includes a track 1, a vehicle body 2 is provided above the track 1, a track wheel 12 is provided below the vehicle body 2, a reducer 11 is provided on the rotating shaft of the front track wheel 12, the reducer 11 (worm gear reducer) main body is fixedly connected to the bottom of the vehicle body 2, the input end of the reducer 11 is connected to a motor 10, a flow groove 3 is provided above the vehicle body 2, a grate 7 is provided at the front end of the flow groove 3, guide wheels 8 are provided on both sides of the rear of the flow groove 3, and a limit frame 5 and a guide frame 6 are provided at the front and rear of the track 1 respectively.

[0021] The two sides of the bottom of the flow channel 3 are interconnected with the vehicle body 2 through the bearing seat 4. The flow channel 3 can swing left and right at the upper end of the vehicle body 2. Tension springs 9 are provided on both sides of the front of the flow channel 3. The lower ends of the tension springs 9 are interconnected with the vehicle body 2.

[0022] A hook 14 is provided below the front end of the flow channel 3 .

[0023] A transverse plate is disposed at the upper end of the limiting frame 5 , and a damper 15 is disposed at the middle portion of the limiting frame 5 .

[0024] A guide plate 13 is disposed above the guide frame 6 . The guide frame 6 is disposed on both sides of the track 1 . The guide wheels 8 can fit the lower surface of the guide plate 13 .

[0025] When using this utility model, first Figure 6 As shown, the top is the pouring ladle, and the reducer 11 is a worm gear reducer with a self-locking function. The motor 10 drives the vehicle body 2 to move. When it moves to the front, the hook 14 is hung on the horizontal plate of the limit frame 5, and one end is locked to prevent the flow channel 3 from flipping left and right (similar to a seesaw). Then the pouring ladle pours the molten iron into the flow channel car and then enters the furnace. The grate 7 peels off the waste. When completed, the vehicle body 2 is driven by the motor 10 to move backward. After moving a certain distance, the guide wheel 8 cuts into the surface of the guide plate 13. At this time, the flow channel 3 tilts backward. Due to the combined effect of inertia and tilt, the waste slag will be discharged from the flow channel 3 and fall into the waste box arranged below. And so on, the execution is repeated to achieve the effect of reducing waste slag and improving the quality of finished products.
