Description

Technical Field

[0001] This patent application belongs to the field of metallurgical casting technology, and more specifically, relates to an apparatus and method for automatically adding ladle diverting agent. Background Technology

[0002] The flow guide agent is a type of filler for the sliding gate of a ladle. Practical experience shows that the automatic opening rate of the ladle castable can reach 99%, making it an ideal filler for the sliding gate of a ladle. It is added to the upper gate before casting, and the heat generated by the combustion of the flow guide agent prevents the molten steel in the upper gate from solidifying, thus achieving automatic opening and avoiding the problem of inclusions in the steel ingot.

[0003] Currently, the addition of ladle priming agent involves manually injecting the agent after the ladle is burned by the tilting machine and the slide plate is replaced. This requires workers to manually align the ladle's sand-adding area. During this manual alignment and sand-adding process, workers' faces are exposed to the high temperature of the ladle, posing a significant safety hazard. The agent is manually added to the inlet area, a slow and inefficient method that cannot accurately deliver the agent to the ladle's inlet, resulting in a low automatic flow rate and substantial agent waste, hindering automatic casting. Furthermore, the need for continuous casting workers to manually burn the inlet for casting increases labor intensity and safety risks, ultimately impacting normal production. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by designing and installing a highly efficient, safe, convenient, and precise automatic and rapid filling device and method for metallurgical steel ladles. Compared with traditional tilting mechanisms for filling, this device requires less space, less infrastructure, and less investment. It is easy to operate and maintain, reduces the labor intensity of employees, eliminates potential safety hazards during production, ensures smooth production, and improves the automatic pouring rate of steel ladles.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: An automatic ladle-filling device includes a first base installed on an argon station platform, a support column on the first base, a rotating ladle-filling transverse wall connected to the support column via a pressure bearing, a counterweight installed at the bottom end of the rotating ladle-filling transverse wall, a second base and a fixed pulley bracket installed at both ends of the upper part of the rotating ladle-filling transverse wall, a fixed pulley installed on the fixed pulley bracket, a chain fixing bolt installed on the upper part of the rotating ladle-filling transverse wall, a multi-functional electric hoist installed on the second base, an encoder and a first chain installed on the multi-functional electric hoist, a chain directional cylinder installed at the bottom end of the front end of the rotating ladle-filling transverse wall, a through hole installed on the rotating ladle-filling transverse wall and communicating with the chain directional cylinder, a second chain fixed at one end to the chain fixing bolt, a ladle hopper connected to the other end of the second chain, a cross beam installed in the ladle, and a central hole installed on the cross beam. One end of the second chain is fixed to the chain fixing bolt, and the other end of the second chain passes through the through hole, the chain direction cylinder, and the center hole of the cross beam and is connected to the diverting agent cone plug. The diverting agent cone plug is located in the diverting agent hopper and is matched with the diverting agent hopper. The first chain and the fixed pulley are on the same horizontal plane. The first chain is wound around the fixed pulley. The first chain is connected to the crossbeam on the cross beam in the diverting agent hopper through the through hole and the chain direction cylinder. The chain retaining bolt is located between the second base and the fixed pulley bracket; The support column is located between the converter process and the argon station process, the second base is located directly above the counterweight, and the multi-functional electric hoist is connected to the main control system.

[0006] Further: The first and second chains are of unequal length.

[0007] Further: The diverting agent cone plug is set at 2 / 3 of the diverting agent hopper volume via a second chain.

[0008] Further information: The model of the multi-functional electric hoist is TSJ-A.

[0009] Further details: The main control system includes a main control computer and a PLC. The main control computer controls the multi-functional electric hoist via the PLC.

[0010] Furthermore: the distance between the chain fixing bolt and the second base is greater than the distance between the chain fixing bolt and the fixed pulley bracket.

[0011] A method for automatically adding draining agent to a ladle, utilizing the aforementioned device, comprises the following steps: During the process of adding the diverting agent to the ladle, the second chain connects the diverting agent cone plug to the diverting agent hopper and sets the diverting agent cone plug at 2 / 3 of the volume of the diverting agent hopper; The main control computer in the main control system is connected and controlled via PLC. The command to start the sand-adding work position / sand-adding standby position is displayed in the main control computer dialog box. This controls the multi-functional electric hoist and the first chain to perform the adding and lifting operations of the diverting agent. The diverting agent hopper descends relative to its original position, and the diverting agent cone plug disengages and opens. Once the diverting agent is added to the ladle, the diverting agent hopper is lifted to a certain height by the multi-functional electric hoist and the first chain. At this point, the diverting agent cone plug engages and blocks the central hole of the diverting agent hopper to add more diverting agent. Due to the adoption of the above technical solution, the beneficial effects achieved by this invention are: This device, a rapid dewatering agent loading system for metallurgical steel ladles, is characterized by high efficiency, safety, convenience, and precision. Compared with traditional tilting mechanisms for dewatering agent loading, this device requires less space, less infrastructure, and less investment. It is also easy to operate and maintain, effectively reducing the labor intensity of employees, eliminating potential safety hazards during production, ensuring smooth production, and increasing the automatic ladle casting rate.

One end of the second chain 13 is fixed to the chain fixing bolt 12, and the other end of the second chain 13 passes through the through hole, the chain direction cylinder 14, and the center hole of the cross beam 17 and is connected to the drainage agent cone plug 16. The drainage agent cone plug 16 is located in the drainage agent hopper 15 and corresponds to and cooperates with the center hole of the drainage agent hopper 15.

[0022] The first chain 9 and the fixed pulley 10 are on the same horizontal plane. The first chain 9 is wound around the fixed pulley 10. The first chain 9 is connected to the crossbeam on the cross beam 17 in the diverting agent hopper 15 through the through hole and the chain direction cylinder 14. The chain fixing bolt 12 is located between the second base 6 and the fixed pulley bracket 11; The support column 2 is located between the converter process and the argon station process, the second base 6 is located directly above the counterweight 5, and the multi-functional electric hoist 7 is connected to the main control system.

[0023] The first chain 9 and the second chain 13 are of unequal length. The diverting agent cone plug 16 is positioned at 1 / 3 to 2 / 3 of the volume of the diverting agent hopper 15 via the second chain 13.

[0025] The main control system includes a main control computer and a PLC. The main control computer controls the multi-functional electric hoist 7 via the PLC.

[0026] The distance between the chain fixing bolt 12 and the second base 6 is greater than the distance between the chain fixing bolt 12 and the fixed pulley bracket 11, that is, the chain fixing bolt 12 is closer to the fixed pulley bracket 11.

[0027] An automatic method for adding a draining agent to a ladle utilizes the aforementioned device. During the process of adding the draining agent to the ladle, a second chain 13 connects the draining agent cone plug 16 to the draining agent hopper 15, and sets the draining agent cone plug 16 at 2 / 3 of the volume of the draining agent hopper 15.

[0028] In the main control system, the main control computer is connected to the PLC for control.

The diverting agent hopper 15 descends relative to its position, and the diverting agent cone plug 16 disengages and opens. Figure 6 After the drainage agent is filled into the ladle, and the drainage agent hopper 15 is lifted to a certain height by the multi-functional electric elevator 7, the drainage agent cone plug 16 engages to block the drainage agent hopper 15, thus adding more drainage agent. Figure 7 .

[0029] Figure 6 , Figure 7 The diagram illustrates the working states of the drainage agent cone plug 16 during standby and operation. In standby mode, the drainage agent cone plug 16 is positioned above the drainage agent hopper 15. During operation, the drainage agent hopper 15 is raised, causing the drainage agent cone plug 16 to engage and block the central hole of the drainage agent hopper 15. There are two central holes in total: one at the center of the cross beam 17 and the other at the center of the drainage agent hopper 15. These two central holes are not located in the same location. Figure 4 , Figure 5 , Figure 6 , Figure 7 These differences are clearly reflected.

[0030] The following examples further illustrate this point.

The chains 9 and 13 are of unequal length.

[0032] During the process of adding the diverting agent to the ladle, the second chain 13 connects the diverting agent cone plug 16 to the diverting agent hopper 15 and sets the diverting agent cone plug 16 at 2 / 3 of the volume of the diverting agent hopper 15. The diverting agent hopper 15 is lowered by relative displacement, and the diverting agent cone plug 16 disengages and opens, allowing the diverting agent to be added to the ladle. After the diverting agent is added to the ladle, when the diverting agent hopper 15 is lifted to a certain height by the multi-functional electric hoist (model: TSJ-A) 7, the diverting agent cone plug 16 engages and blocks the central hole of the diverting agent hopper 15 to add the diverting agent.
