Description

Technical Field

[0001] The present application belongs to the technical field of steelmaking and continuous casting, and in particular relates to a continuous casting production line. Background Art

[0002] Continuous casting is the abbreviation of continuous steel casting. It is an advanced casting method. Its main principle is to continuously pour molten metal liquid into a special steel container called a crystallizer. The molten steel continues to solidify in the crystallizer (the molten steel continues to form a crust) and the casting is then continuously pulled out from the other end of the crystallizer. It mainly obtains any specific length according to the production plan, greatly improving the production capacity of the steel plant. The rapid development of continuous casting technology is one of the important means for my country's metallurgical industry to achieve structural optimization. Ensuring its good operation has a good driving effect on improving the current low efficiency and high consumption production status of enterprises. At the same time, it will also greatly promote the further optimization and upgrading of my country's product structure to a certain extent, and gradually develop towards specialization. On the other hand, the rapid development of advanced technologies such as near-net shape continuous casting and high-efficiency green continuous casting technology has also driven the research and development of a number of high value-added new materials.

[0003] The lower part of the continuous casting trench cutting roller is mainly used for drainage. In related technologies, the steel slag generated during the continuous casting process will fall into the continuous casting trench, which can easily cause blockage of the continuous casting trench. In daily production, once the trench is blocked, it will seriously affect the casting stability of the casting machine. At the same time, it will also require a lot of additional production time to clean up the accumulated slag, resulting in a large amount of manpower and material costs. In the daily production application of the casting machine, the main method of cleaning is to continuously flush it with slag water to prevent the continuous casting trench from accumulating slag for a long time and causing adverse effects on production.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In addition, in this utility model, the descriptions of "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0036] In the related art, there is a technical problem that the continuous casting trench is easily blocked by steel slag. The embodiment of the present application provides a continuous casting production line, which can at least to some extent solve the technical problem that the continuous casting trench is easily blocked by steel slag.

[0037] like Figure 1 and Figure 2 As shown, the continuous casting production line 100 includes a cutting roller table 110 , a continuous casting trench 120 , a strand cutting vehicle 130 , a guide slide 140 and a slag receiving bucket 150 .

[0038] The cutting rollers 110 are used to transport the cast strands. Molten steel from the ladle is poured into the segments. After cooling and solidifying within the segments, the strands are formed. The strands are then transferred to the cutting rollers 110 and transported forward along their conveying direction. The structures of the segments and cutting rollers 110 are diverse and well known to those skilled in the art, so detailed description is omitted here.

[0039] The continuous casting trench 120 is arranged below the cutting roller 110 along the length direction of the cutting roller 110. The continuous casting trench 120 is arranged below the cutting roller 110 to receive liquid, slag, etc. falling from above.

[0040] The slab cutting car 130 is used to cut the slabs and can move along the length direction of the cutting roller 110. The slab cutting car 130 is used to cut the slabs. Since continuous casting is a continuous production process, that is, the molten steel will be continuously cast into the fan-shaped segment to cool and solidify, and the slabs will be continuously formed. The slabs are continuously transported forward during the entire process. Therefore, the slab cutting car 130 needs to move along the length direction of the cutting roller 110 to keep adapting to the transmission rate of the slabs to ensure that the slab cutting car 130 can smoothly cut the slabs. The slab cutting car 130 can be installed on the cutting roller 110. Of course, it can also be installed on a support platform such as a steel structure or concrete where the roller is located. The slab cutting car 130 can be a flame cutting car.

[0041] The guide slide 140 is disposed below the roller conveyor. The guide slide 140 has a chute 141 arranged at an angle to the horizontal plane. At least a portion of the chute 141 is located under the movement path of the slab cutting vehicle 130. The chute 141 of the guide slide 140 is used to receive slag formed by the slab cutting machine when cutting the slabs. Therefore, at least a portion of the chute 141 is located under the movement path of the slab cutting vehicle 130. In other words, the chute 141 is not required to receive slag dropped from various locations by the slab cutting vehicle 130. Instead, the chute 141 is required to receive slag formed by the slab cutting vehicle 130 when cutting the slabs at at least one location, so that at least a portion of the slag formed by the slab cutting vehicle 130 when cutting the slabs can fall into the chute 141, thereby reducing the amount of slag falling into the continuous casting trench 120 to a certain extent. Of course, for the present application, it is preferred that the chute 141 be able to receive the slag produced by the movement of the ingot cutting car 130 to various locations, so as to receive all the slag formed by the ingot cutting car 130 and greatly reduce the amount of slag falling into the continuous casting trench 120. The present application requires that the chute 141 be inclined to the horizontal plane so that the slag falling into the chute 141 can move downward along the inclined direction of the chute 141 under the action of gravity and be discharged into the slag receiving hopper 150. The cutting roller 110 includes components such as rollers, roller mounting seats, and a drive motor. The guide slide 140 can be fixedly mounted on the roller mounting seat. Of course, the guide slide 140 can also be fixedly mounted on the side wall of the continuous casting trench 120, which is not limited in the present application. In some embodiments, the guide slide 140 is fixedly mounted on the roller mounting seat.

[0042] The slag receiving hopper 150 is placed in the continuous casting trench 120. The slag receiving hopper 150 has a slag receiving trough 151. The opening 1511 of the slag receiving trough 151 is located below the slag outlet 142 of the chute 141, and is used to receive the slag discharged from the slag outlet 142 of the chute 141. The slag outlet 142 of the chute 141 is located at the lower end of the chute 141, and the steel slag is discharged from the chute 141 through the slag outlet 142. After the steel slag is discharged from the slag outlet 142 of the chute 141, it falls through the opening 1511 and enters the slag receiving trough 151, and is collected by the slag receiving trough 151. The slag receiving hopper 150 can be placed directly in the continuous casting trench 120. Of course, the slag receiving hopper 150 can also be fixed on the cutting roller 110 or the guide slide 140, which is not limited in this application.

[0043] According to the above design, the steel slag formed during the ingot cutting process is collected in the slag receiving bucket 150 instead of accumulating in the continuous casting trench 120, which solves the problem that the continuous casting trench 120 is easily blocked by steel slag. After such design, the steel slag is collected in the slag receiving bucket 150. The staff lifts the slag receiving bucket 150 out of the continuous casting trench 120 and dumps the slag receiving bucket 150 to clean the steel slag. The cleaning is more convenient, which helps to save the workers' labor intensity and improve the operating efficiency of the continuous casting production line 100.

[0044] After the ingot is discharged from the sector, its temperature is relatively high. Heat is also released when the ingot cutting vehicle 130 cuts the ingot. Therefore, the slag formed by the cutting machine when cutting the ingot is extremely hot. If the slag falls directly onto the guide runner 140, it is likely to adhere to the guide runner 140. Furthermore, the slag will adhere to each other, making it difficult to clean and easily causing slag to accumulate on the guide runner 140. Therefore, in some embodiments, the continuous casting production line 100 further includes a first spray member 160 mounted on the ingot cutting vehicle 130. The water outlet of the first spray member 160 is positioned toward the cutting area of ​​the ingot cutting vehicle 130. The water outlet of the first spray member 160 is positioned toward the cutting area of ​​the ingot cutting vehicle 130. The first spray member 160 is configured to spray cooling water to cool the slag. This cooling of the slag prevents the slag from adhering to the guide runner 140 to a certain extent, thereby extending the service life of the guide runner 140.

[0045] The first spray element 160 may include a nozzle and a pipe, one end of the pipe being connected to a water source, and a nozzle mounted at the other end of the pipe. Cooling water is sprayed through the nozzle toward the cutting area of ​​the strand cutting vehicle 130. Alternatively, the first spray element 160 may include only a pipe, one end of the pipe being connected to a water source, and cooling water being discharged directly through the other end of the pipe, which is directed toward the cutting area of ​​the strand cutting vehicle 130. The structure of the first spray element 160 is diverse and is not limited in this application.

[0046] In some embodiments, the ingot cutting car 130 is a flame cutting car. In these embodiments, the first spray part 160 includes a nozzle and a pipe. One end of the pipe is connected to the cooling water network in the factory, and a plurality of nozzles are installed on the other end of the pipe. In these schemes, the nozzle is located below the cutting gun of the flame cutting car to reduce the interference of the cooling water on the flame.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments, the guide slide 140 includes a guide slide bottom plate 143, a guide slide first side plate 144 and a guide slide second side plate 145, the guide slide first side plate 144 and the guide slide second side plate 145 are arranged opposite to each other, the guide slide bottom plate 143 is connected to the guide slide first side plate 144 and the guide slide second side plate 145, the guide slide bottom plate 143 is set at an angle to the horizontal plane, and the guide slide bottom plate 143, the guide slide first side plate 144 and the guide slide second side plate 145 together form a chute 141.

[0048] The first and second side plates 144, 145 of the guide runner are disposed opposite each other. The guide runner base plate 143 is disposed below the first and second side plates 144, 145 and is fixedly connected to both. The guide runner base plate 143 is tilted so that the resulting chute 141 is tilted relative to the horizontal plane, allowing slag to slide downward along the guide runner base plate 143. In these embodiments, the upper ends of the first and second side plates 144, 145 can be welded to the roller mounting base.

[0049] In some embodiments, the guide slide 140 also includes two connecting plates 146, which are horizontally arranged. One connecting plate 146 is fixedly connected to the first side plate 144 of the guide slide, and the other connecting plate 146 is fixedly connected to the second side plate 145 of the guide slide. Bolt through holes are opened on the connecting plates 146, and the connecting plates 146 are fixedly connected to the roller mounting seat by bolts passing through the bolt through holes.

[0050] In some embodiments, the slide guide bottom plate 143 includes a first slide guide bottom plate section 1431 and a second slide guide bottom plate section 1432 connected to each other. Along the movement direction of the slag, the second slide guide bottom plate section 1432 is located in front of the first slide guide bottom plate section 1431. The first slide guide bottom plate section 1431 and the second slide guide bottom plate section 1432 are arranged at an obtuse angle, and the first angle α between the first slide guide bottom plate section 1431 and the horizontal plane is greater than the second angle β between the second slide guide bottom plate section 1432 and the horizontal plane.

[0051] With this design, the inclination angle of the first section 1431 of the guide plate bottom plate is greater than the inclination angle of the second section 1432 of the guide plate bottom plate, that is, the first section 1431 of the guide plate bottom plate is steeper. The slag is discharged from the end of the second section 1432 of the guide plate bottom plate away from the first section 1431 of the guide plate bottom plate. The movement path of the slag falling on the first section 1431 of the guide plate bottom plate is longer than the movement path of the slag falling on the second section 1432 of the guide plate bottom plate. This design can make the slag falling on the first section 1431 of the guide plate bottom plate experience a greater tangential component of gravity in a direction parallel to the first section 1431 of the guide plate bottom plate (i.e., the force that drives the slag downward along the first section 1431 of the guide plate bottom plate). This can increase the movement speed of the slag on the first section 1431 of the guide plate bottom plate, allowing the slag on the first section 1431 to be discharged quickly.

[0052] In some embodiments, the first angle α is 40°-45°, and the second angle β is 15°-20°.

[0053] In some embodiments, the width of the chute 141 tends to decrease along the moving direction of the slag.

[0054] That is, along the movement direction of the slag, the width of the chute 141 gradually decreases. This design enables the slag to gradually gather together during its movement on the guide slide 140, making it easier for the slag receiving bucket 150 to collect the slag.

[0055] In some embodiments, the continuous casting production line 100 further includes a second spray member 170 mounted on the first side plate 144 and / or the second side plate 145 of the guide slide. The water outlet of the second spray member 170 is located in the chute 141 and faces the guide slide bottom plate 143. The second spray member 170 sprays liquid onto the guide slide bottom plate 143 to accelerate the movement of the slag on the guide slide 140 so that the slag can be quickly collected in the slag receiving hopper 150. In some embodiments, the second spray member 170 includes a pipe and a nozzle. One end of the pipe is connected to the cooling water network in the factory building, and the nozzle is installed at the other end of the pipe.

[0056] like Figure 5 、 Figure 6 and Figure 7 As shown, in some embodiments, the slag hopper 150 includes a slag hopper bottom plate 152 and multiple slag hopper side plates 153. The slag hopper bottom plate 152 is connected to the multiple slag hopper side plates 153. The slag hopper side plates 153 are connected in sequence. The slag hopper bottom plate 152 and the slag hopper side plates 153 together form a slag trough 151.

[0057] Multiple hopper side panels 153 are connected end to end to form a ring structure, and the hopper side panels 153 are connected to the lower portions of these hopper side panels 153, thereby enclosing a slag trough 151. The number of hopper side panels 153 can be two, three, four, etc., and is not limited in this application. In some embodiments, the number of hopper side panels 153 is four, and the hopper 150 layers are isosceles trapezoidal. The cross-section of the slag trough 151 formed by the enclosed slag trough 151 is rectangular, and the slag trough 151 is larger at the top and smaller at the bottom.

[0058] In order to reduce the labor intensity of workers, in some embodiments, the slag receiving bucket 150 also includes a lifting lug 155 and a flip lug 156 set on the slag receiving bucket side plate 153, and the lifting lug 155 is located above the flip lug 156. After the lifting lug 155 is set, the slag receiving bucket 150 can be lifted by a crane in the factory and lifted out of the continuous casting trench 120, thereby reducing the labor intensity of manual labor. The cutting roller 110 includes a roller mounting seat and a plurality of rollers that are spaced and rotatably set on the roller mounting seat. There is a gap between two adjacent rollers. When the slag receiving bucket 150 is lifted, the slag receiving bucket 150 can pass through the cutting roller 110 through the gap between the two adjacent rollers, thereby ensuring that the slag receiving bucket 150 can be lifted out of the continuous casting trench 120 by the crane. When using the continuous casting production line 100 of the present application, the size of the slag receiving bucket 150 should be smaller than the gap between the two rollers so that the slag receiving bucket 150 can pass through the gap between the two rollers and pass through the cutting roller 110.

[0059] The flip lug 156 is disposed below the hoisting lug 155 so that when the hoisting lug 155 of the slag receiving bucket 150 is hoisted by a crane, the crane can also hoist the flip lug 156 and lift the flip lug 156 upward, thereby flipping the slag receiving bucket 150 and pouring out the slag in the slag receiving bucket 150. Specifically, the main hook of the crane is hung on the hoisting lug 155, and the auxiliary hook is hung on the flip lug 156. By lifting the main hook, the slag receiving bucket 150 can be lifted out of the continuous casting trench 120, and by lifting the flip lug 156, the slag receiving bucket 150 can be flipped.

[0060] In some embodiments, the bottom plate 152 of the slag hopper is provided with a filter hole 154, and / or the side plate 153 of the slag hopper is provided with a filter hole 154 on a side close to the bottom plate 152 of the slag hopper. The provision of the filter hole 154 allows the cooling water and the like in the slag trough 151 to be promptly discharged from the slag trough 151. It is easy to understand that the filter hole 154 is a through hole, and multiple filter holes 154 can be provided to increase the rate of cooling water discharge. In some embodiments, the filter hole 154 is provided on both the bottom plate 152 and the side plate 153 of the slag hopper.
