Description

Technical Field

[0001] The present invention relates to the technical field of furnace production, and in particular to a furnace production system and a scheduling method thereof which are conducive to safe and efficient operation and maintenance. Background Art

[0002] Induction melting furnace or induction melting furnace is a short-process steelmaking and melting equipment, and is also a general-purpose equipment for metallurgical casting, which is used to melt metal return materials into liquid state. Due to the short service life of the furnace lining, it is necessary to frequently build the furnace lining, and slowly heat up and bake and sinter the new furnace lining of the first furnace. In the absence of a spare furnace, the cooling and removal of the entire old furnace lining, as well as the building, baking and sintering of the new furnace lining take a lot of time, resulting in a significant decrease in production capacity and low equipment utilization.

[0003] In order to improve equipment utilization and production capacity, the current furnace production system mainly adopts one power plant and two furnaces (one in use and one in reserve) or two power plants and three furnaces (two in use and one in reserve). The above furnace production system has the following main defects: 1. The number of spare furnaces is limited, for example, two furnaces are used and one is used as a spare furnace; 2. The standby furnace usually has to be operated online (repairing and lining, maintenance and repair, etc.), that is, it must be operated on site without disconnecting the water and electricity connections or moving the furnace body; 3. When the working furnace next to the standby furnace is in operation, it poses a great safety hazard to the standby furnace within the splashing range of the molten metal liquid; 4. Even in rare application cases, if the production workshop has the basic conditions to transport the spare furnace to the maintenance station by crane, the efficiency is relatively low and there are certain safety risks. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, to provide a furnace production system that can improve the replacement efficiency and maintenance safety of the furnace, and to provide a scheduling method based on the production system.

[0005] The technical solution adopted by the present invention is as follows: A furnace production system that facilitates safe and efficient operation and maintenance, comprising: Several workstations are equipped with pedestals; Several furnaces are installed on a pedestal with space reserved at the bottom of the furnace; A plurality of longitudinal tracks, each of which is connected to at least one working position; At least one transverse track arranged crosswise with the longitudinal track; The middle transfer position is located at the intersection of the longitudinal track and the transverse track and is provided with a pedestal; The maintenance area is set at a position away from the working position and outside the distance radius that meets the safety regulations, and has at least one maintenance position connected to the longitudinal track or the transverse track, and each maintenance position is provided with a pedestal; The waiting area has at least one waiting position connected to the longitudinal track or the transverse track, and each waiting position is provided with a pedestal; The transfer vehicle travels on the longitudinal track and / or the transverse track and can enter the space between the furnace and the pedestal. The transfer vehicle is provided with a supporting mechanism for driving the furnace to rise and fall to separate from the pedestal.

[0006] In a further solution, the furnace is provided with a plurality of supporting points, and the supporting mechanism drives the furnace to be raised and lowered via the supporting points.

[0007] In a further solution, the longitudinal track passes through the ground plane projection of the working position, so that the transfer vehicle can move to the space below the furnace to complete the lifting action.

[0008] In a further solution, the transfer vehicle fixes the furnace it carries by means of an anti-slip fixing mechanism.

[0009] In a further solution, the transfer vehicle includes a longitudinal transfer vehicle and a transverse transfer vehicle, the longitudinal transfer vehicle is adapted to the longitudinal track, and the transverse transfer vehicle is adapted to the transverse track.

[0010] In a further solution, the transfer vehicle has a longitudinal walking component, a transverse walking component and a switching mechanism. The longitudinal walking component is adapted to the longitudinal track, and the transverse walking component is adapted to the transverse track. The switching mechanism switches to the corresponding walking component to work according to the track on which the transfer vehicle needs to travel.

[0011] In a further solution, the transfer vehicle has a traveling mechanism that can travel on longitudinal tracks and transverse tracks, and the traveling mechanism is provided with a wheel in-situ steering mechanism, so as to achieve steering on the longitudinal track and the transverse track in the mid-transfer position.

[0012] In a further solution, the maintenance area is connected to the longitudinal track or the transverse track in such a way that the maintenance area is arranged at or near a position that can be reached by the track.

[0013] In a further solution, the standby area is connected to the longitudinal track or the transverse track in such a way that the standby area is arranged at or near a position that can be reached by the track.

[0014] Another technical solution of the present invention is: a scheduling method, using the above-mentioned furnace production system, comprising: Use a transfer vehicle to transfer the furnace that needs to be replaced offline from the working position to the transfer position, and then transfer it to the vacant maintenance position in the maintenance area; Use a transfer vehicle to transfer the repaired furnace or new furnace in the standby area to the transfer position, and then transfer it to the corresponding work position; After the furnace in the maintenance area is overhauled, it is transported to an empty standby position in the standby area using a transfer vehicle to wait for the next replacement.

[0015] The beneficial effects of the present invention are: (1) The space at the bottom of the furnace is used to allow the transfer vehicle to enter and exit, and then the furnaces to be taken offline for maintenance and put online for work are transported to the corresponding workstations by rail operation, thereby improving the replacement efficiency of the induction furnace; (2) By utilizing the extendable characteristics of the track, the maintenance area and the standby area are separated, and online maintenance is not required. Maintenance does not affect the online operation of the furnace, so that the entire induction furnace can be dismantled and replaced in an orderly manner, further improving the replacement efficiency; (3) The maintenance area is located far away from the work station and outside the distance radius that meets safety regulations, which greatly improves the safety of operators; (4) Workstations can be set up and tracks can be laid according to local conditions, which improves the space utilization rate in the workshop and avoids the risk of high-altitude lifting; (5) The standby area can be equipped with multiple standby positions to increase the number of spare furnaces; the maintenance area can be equipped with multiple maintenance positions to adapt to the production system with multiple furnaces.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] It will be understood that the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] Embodiment 1: See also Figure 1 As shown, this embodiment provides a furnace production system that is conducive to safe and efficient operation and maintenance, including: four furnaces 1, three working positions 2, three longitudinal tracks 3, one transverse track 4, three transfer positions 5, a maintenance area 6, a standby area 7, and four transfer vehicles 8.

[0028] Among them, three of the four furnaces are used as working furnaces and one is used as a standby furnace. The three working furnaces are installed on three working positions 2 respectively, and each working position 2 leads out a longitudinal track 3. The transverse track 4 is arranged vertically and crosswise with each longitudinal track 3, and the intersection forms the above-mentioned three transfer positions 5. The transfer vehicle 8 is divided into three longitudinal transfer vehicles and one transverse transfer vehicle. The longitudinal transfer vehicle is adapted to the longitudinal track, and the transverse transfer vehicle is adapted to the transverse track, and both can reciprocate on the corresponding track.

[0029] The furnace working position 2 is the position where the furnace 1 is normally produced. The furnace of the furnace 1 is filled with high-temperature molten metal liquid, and the inductor of the furnace carries high voltage during operation. Therefore, for the safety of personnel, the specification usually requires that there should be no crowded areas or working areas within a certain distance radius from the furnace. However, in terms of the current traditional furnace production system, the maintenance work of the furnace is usually carried out on-site after a power outage, while the working furnace not far from the maintenance furnace continues to produce, which poses certain safety hazards.

[0030] In this embodiment, the maintenance area 6 and the standby area 7 are arranged at both ends of the transverse track 4, and the maintenance area 5 is set at a position away from any working position and outside the distance radius that meets safety regulations.

[0031] In the present application, the number of maintenance positions in the maintenance area 6 and the number of standby positions in the standby area 7 can be set according to the number of furnaces. Figure 1 Shown is 1 maintenance position and 1 standby position. In other embodiments, the maintenance area 6 may also be provided with 2 to 4 maintenance positions, and the standby area 7 may be provided with 2 to 4 standby positions. The maintenance positions are connected in series via rails, and the standby positions are connected in series via rails. When the transfer vehicle 8 transfers the furnaces in the maintenance area 7 and the standby area 6, the furnace closest to the transfer position 5 is preferentially transferred.

[0032] The working position 2, the transfer position 5, the maintenance position, and the standby position are all provided with a pedestal for installing and fixing or temporarily supporting the furnace 1. The transfer vehicle 8 is provided with a supporting mechanism for driving the furnace to be lifted and lowered to separate from the pedestal. The supporting mechanism can adopt an existing mechanism. For example, in one embodiment, the supporting mechanism includes a plurality of jacks, or a lifting platform using a jack as a power source.

[0033] The bottom of the furnace 1 is reserved with space to allow the transfer vehicle 8 to pass through and lift up. This space can be the space at the bottom of the furnace 1 itself, or the space reserved on the pedestal, or a combination of the two. The furnace 1 is provided with a number of support points that are supported by the support mechanism of the transfer vehicle. These support points are arranged in the space at the bottom of the furnace, or other parts of the furnace that can be lifted by the support mechanism. After the support mechanism is raised, it presses against the support points to lift the furnace 1 up and away from the pedestal. Similarly, after the support mechanism is lowered, the furnace 1 can be placed on the pedestal.

[0034] The longitudinal track 3 passes through the ground plane projection of the working position 2, so that the transfer vehicle can use the track to move to the space below the furnace to complete the lifting action.

[0035] The transfer vehicle 8 fixes the furnace 1 it carries through an anti-skid fixing mechanism. The main function of the anti-skid fixing mechanism is to prevent it from falling from the transfer vehicle during transportation. This can be achieved in a variety of ways. For example, in one embodiment, the anti-skid fixing mechanism can use bolts and nuts to fix the furnace 1 to the transfer vehicle 8. In another embodiment, the anti-skid fixing mechanism uses a hydraulic lock or a hydraulic clamp. In yet another embodiment, the anti-skid fixing mechanism uses a restraint belt.

[0036] In this embodiment, the maintenance area is connected to the transverse track in such a way that the maintenance area is arranged at or near a position that the transverse track can reach. The standby area is connected to the transverse track in such a way that the standby area is arranged at or near a position that the transverse track can reach.

[0037] The working principle of this embodiment is: When a working furnace needs to be taken offline for maintenance, the water and electricity connections of the working furnace are disconnected, and the longitudinal transfer vehicle on the longitudinal track corresponding to the working furnace is controlled to drive under the furnace. The supporting mechanism of the longitudinal transfer vehicle lifts the furnace and fixes it through the anti-slip fixing mechanism, and then transports it to the corresponding transfer position; the longitudinal transfer vehicle puts down the furnace at the transfer position and then drives away from the transfer position; Then, the horizontal transfer vehicle on the horizontal track is controlled to drive under the furnace, lift the furnace, fix it through the anti-slip fixing mechanism, and transport it to the maintenance area so that the staff can carry out maintenance work; the furnace in the standby area is then transported to the corresponding transfer position by the horizontal transfer vehicle, and the furnace is transported to the corresponding work position for installation by the corresponding longitudinal transfer vehicle, thus completing the replacement of the induction furnace; After the furnace is transported to the maintenance area and inspected by the staff, it is transported to the standby area at the other end by a horizontal transfer vehicle, waiting for the next induction furnace replacement work.

[0038] Embodiment 2: See also Figure 2 As shown, the difference from Example 1 is that this embodiment includes: three furnaces 1, two working positions 2, two longitudinal tracks 3, one transverse track 4, two transfer positions 5, two maintenance areas 6, two standby areas 7, and three transfer vehicles 8.

[0039] Among them, two of the three furnaces are used as working furnaces, and one is used as a standby furnace. The two working furnaces correspond to two working positions and two longitudinal tracks. The transfer vehicles are divided into two longitudinal transfer vehicles and one transverse transfer vehicle. The maintenance area is arranged at the other end of the longitudinal track corresponding to the working position, away from the working position and outside the distance radius that meets safety regulations. The standby area is arranged at both ends of the transverse track. Similar to Example 1, in this embodiment, the number of maintenance positions in the maintenance area 6 and the number of standby positions in the standby area 7 can be set according to the number of furnaces.

[0040] The working principle of this embodiment is: When a working furnace needs to be taken offline for maintenance, the water and electricity connections of the working furnace are disconnected, and the longitudinal transfer vehicle on the longitudinal track corresponding to the working furnace is controlled to drive under the furnace, lift the furnace and fix it through the anti-slip fixing mechanism, and then transport it to the corresponding maintenance area to wait for the staff to perform maintenance operations; By controlling the transfer vehicle on the transverse track, the repaired or brand new furnace located in the waiting area at either end of the transverse track is transported to the corresponding transfer position, and then the corresponding longitudinal transfer vehicle is controlled to transport the furnace to its working position for installation, thus completing the replacement of the induction furnace; After the furnace is transported to the maintenance area and inspected by the staff, it is again transferred to the nearest standby area through the longitudinal transfer vehicle and the transverse transfer vehicle at the transfer position, waiting for the next induction furnace replacement work.

[0041] Embodiment 3: See also Figure 3 As shown, the difference from Example 1 is that this embodiment includes: four furnaces 1, three working positions 2, three longitudinal tracks 3, one transverse track 4, three transfer positions 5, a maintenance area 6, a standby area 7, and a transfer vehicle 8.

[0042] The transfer vehicle 8 can switch between the longitudinal track 3 and the transverse track 4 and continue to move. There are at least two implementation methods for realizing the above function.

[0043] One implementation method is as follows: the transfer vehicle has a longitudinal walking component, a transverse walking component and a switching mechanism. The longitudinal walking component is adapted to the longitudinal track, and the transverse walking component is adapted to the transverse track. The switching mechanism switches to the corresponding walking component to work according to the track on which the transfer vehicle needs to travel. The above-mentioned walking components are wheels and drive motors adapted to the tracks. The switching mechanism can use a controller. When traveling on the longitudinal track, the controller controls the motor of the longitudinal walking component to work, and the motor of the transverse walking component does not work. After reaching the transfer position, after the wheels of the transverse control component are aligned with the transverse track, the controller shuts down the longitudinal walking component, and the transverse walking component walks on the transverse track. The above-mentioned walking components and controllers can be implemented with reference to the prior art and will not be further introduced.

[0044] Another embodiment is: the transfer vehicle has a running mechanism that can travel on the longitudinal track and the transverse track, the running mechanism is wheels and a drive motor that are compatible with both the longitudinal track and the transverse track, and the running mechanism is provided with a wheel in-situ steering mechanism, so as to realize the steering from the longitudinal track to the transverse track and from the transverse track to the longitudinal track in the mid-transfer position. The wheel in-situ steering mechanism can be realized by referring to the existing technology and will not be further described.

[0045] Three of the four furnaces in this embodiment are used as working furnaces, and one is used as a standby furnace. The three working furnaces correspond to three working positions and three longitudinal tracks. The maintenance area and the standby area are arranged at both ends of the transverse track, and the maintenance area is set at a position away from any working position and outside the distance radius that meets safety regulations. Similar to Example 1, in this embodiment, the number of maintenance positions in the maintenance area 6 and the number of standby positions in the standby area 7 can be set according to the number of furnaces.

[0046] The working principle of this embodiment is as follows: when a working furnace needs to be taken offline for maintenance, the water and electricity connections of the working furnace are disconnected, and the transfer vehicle can be controlled to drive under the furnace, lift the furnace and fix it through an anti-slip fixing mechanism, and then transport it to the corresponding transfer position; At the transfer position, the transfer vehicle completes the on-site track change from the longitudinal track to the transverse track through its wheel on-site steering or switching mechanism, thereby continuing to transport the furnace to the maintenance area at one end of the transverse track so that the staff can carry out maintenance work; after the transfer vehicle successfully places the furnace in the maintenance area, it continues to drive along the transverse track into the waiting area at the other end, and transports the furnace in the waiting area to the corresponding transfer position; The transfer vehicle again completes the on-site track change from the transverse track to the longitudinal track by turning its wheels on-site or switching the mechanism at the intermediate transfer position, and finally transports the furnace to the working position at one end of the longitudinal track for installation, thus completing the replacement of the induction furnace; After the furnace transported to the maintenance area has been inspected by the staff, it can be transported to the standby area at the other end by a transfer vehicle to wait for the next induction furnace replacement work.

[0047] Embodiment 4: refer to Figure 4 As shown, the difference from Example 2 is that in this embodiment, the standby area is arranged at the other end of the longitudinal track corresponding to the working position, and the maintenance area is arranged at both ends of the transverse track, away from the working position and outside the distance radius that meets the safety regulations. Similar to Example 1, in this embodiment, the number of maintenance positions in the maintenance area 6 and the number of standby positions in the standby area 7 can be set according to the number of furnaces.

[0048] The working principle of this embodiment is: When a working furnace needs to be taken offline for maintenance, the water and electricity connections of the working furnace are disconnected, and the longitudinal transfer vehicle on the longitudinal track corresponding to the working furnace is controlled to drive under the furnace. The supporting mechanism of the longitudinal transfer vehicle lifts the furnace and fixes it through the anti-slip fixing mechanism, and then transports it to the corresponding transfer position; after the longitudinal transfer vehicle puts down the furnace at the transfer position, it drives away from the transfer position (it is recommended to drive to the standby area 7 corresponding to the working position 2); By controlling the transverse transfer vehicle on the transverse track to drive under the furnace, the furnace is lifted and fixed by the anti-slip fixing mechanism, and then transported to the nearest maintenance area 6 for the staff to carry out maintenance work; and then the furnace with the previous maintenance number or the new furnace in the standby area 7 is transported to the corresponding work station for installation by the longitudinal transfer vehicle, completing the replacement of the induction furnace; After the furnace is transported to the maintenance area and inspected by the staff, it is handed over at the transfer position by the horizontal transfer vehicle and the longitudinal transfer vehicle, and the furnace is transported to the nearest standby area to wait for the next induction furnace replacement work.

[0049] Embodiment 5: This embodiment provides a scheduling method, which is applied to any furnace production system of Embodiments 1-4, and includes the following steps: S1. Use a transfer vehicle to transfer the furnace that needs to be replaced offline from the working position to the transfer position, and then transfer it to the vacant maintenance position in the maintenance area; S2. Use a transfer vehicle to transfer the repaired furnace or new furnace in the standby area to the transfer position, and then transfer it to the corresponding work position; S3. After the furnace in the maintenance area is overhauled, it is transported to an empty standby position in the standby area using a transfer vehicle to wait for the next replacement.

[0050] In one embodiment, when multiple furnaces need to be taken offline for replacement, the furnace that is taken offline first is preferentially transferred to the vacant maintenance position at the farthest end of the corresponding track, and then arranged to each vacant maintenance position from far to near; when transferring the furnace from the maintenance area to the standby area, it is preferentially transferred from the nearest maintenance position to the farthest vacant standby position in the standby area; when transferring the furnace from the standby position to the working position, it is preferentially transferred from the nearest standby position to the working position.

[0051] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
