[0014] As a further solution of the present invention, a supercharger is installed on one side of the top of the box cover, and a connecting pipe is installed at the bottom of the supercharger. The connecting pipe is installed on the box cover and communicated with the inside of the box body.

[0015] A construction method for a ladle working layer casting device, the construction method comprising the following steps:

[0016] Before pouring, the ladle needs to be inspected to ensure that it is intact, and the casting material is selected according to the casting requirements of the ladle working layer. When pouring the outer ring working layer of the ladle, the casting material is 60-80mm carbon-free corundum spinel casting material. The casting material is added into the box through the material pipe, and water is added in the specified proportion for stirring;

[0017] The motor is controlled to drive the main shaft to rotate, and the main shaft drives the auxiliary rod to rotate through the connecting seat. Since the auxiliary rod is connected to a gear outside, and the top of the auxiliary rod is connected to the connecting seat through a bearing seat, the auxiliary rod can rotate in the bearing seat. Since the gear is meshed with the gear ring inside the box, while the connecting seat drives the auxiliary rod and the gear to rotate, the auxiliary rod can rotate by itself, so that the main shaft and the auxiliary rod respectively drive multiple blades to rotate and mix and stir the casting material in the box. The auxiliary rod can make a circular motion around the main shaft while rotating, so that the casting material can be mixed in multiple directions.

[0018] After completing the mixing of the pouring material, push the push handle in the support assembly to drive the fixed frame and the box to move, so that the universal wheel at the bottom of the fixed frame can roll on the ground, and move the pouring device to just above the ladle, so that the ladle is located inside the fixed frame. When pouring the working layer of the ladle, the winding machine is controlled to drive the rope drum to rotate, and the rope drum releases the four pull ropes, and the elastic force of the spring is used to support the sliding sleeve, so that the sliding sleeve drives the connecting rod to move, and the connecting rod drives the flexible tube to move through the adjusting frame, so that the four flexible tubes can move away from each other until the bottom of the flexible tube. Located just above the working layer of the ladle, four electrically controlled valve tubes are opened at the same time, so that the casting material inside the box can be discharged from the bottom end of the flexible tube through the electrically controlled valve tube, and the push handle is rotated by holding it, and the push handle drives the support ring seat and the box to rotate through the fixed rod. Because the box body is connected to the fixed frame through the support bearing outside, it plays a role in supporting the box body, thereby improving the rotation stability of the box body. The box body drives the winding assembly at the bottom to rotate, so that the flexible tube in the winding assembly can revolve around the center of the ladle, so that the casting material can be filled into the working layer of the ladle from multiple directions at the same time;

[0019] During the pouring process, the vibrating rod can be inserted into the socket in the adjustment frame, and the vibrating rod can be limited by the socket so that the vibrating rod can be stably placed in the steel bar working layer. The vibrating rod can be controlled to vibrate while pouring, thereby preventing the pouring material from hollowing, so that the pouring work and the vibrating work can be completed synchronously, ensuring the compactness of the pouring material and improving the pouring efficiency. When the pouring speed needs to be adjusted, the booster on the top of the control box cover works, and the booster pressurizes the inside of the box through the connecting pipe, so as to increase the discharge speed of the electric control valve pipe;

[0020] After the pouring work is completed, the pouring device is removed, the working layer of the ladle is baked, dried and sintered, and after the mold is removed from the ladle, the ladle is baked at low temperature according to the heating curve. When the temperature reaches 200-300℃, it is baked for more than 24 hours.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention moves the pouring device to the top of the ladle so that the ladle is located inside the fixed frame. When pouring the working layer of the ladle, the winding machine is controlled to drive the rope drum to rotate. The rope drum releases four pull ropes and supports the sliding sleeve with the elastic force of the spring, so that the sliding sleeve drives the connecting rod to move. The connecting rod drives the flexible tube to move through the adjusting frame, so that the four flexible tubes can move away from each other until the bottom end of the flexible tube is located above the working layer of the ladle. At the same time, the four electric control valve tubes are opened so that the pouring material inside the box can pass through the electric control valve tube. The valve tube is discharged from the bottom end of the flexible tube, and the push handle is held to rotate. The push handle drives the box to rotate through the fixed rod, and cooperates with the box to drive the flexible tube to revolve around the center of the ladle, so that the casting material can be filled into the working layer of the ladle from multiple directions at the same time, abandoning the traditional single-point casting method, so that the casting material can be evenly distributed in the working layer of the ladle, and the socket in the adjustment frame is used to place the vibrating rod, so that the vibrating rod can be stably placed in the working layer of the ladle, so that the casting work and vibration work can be completed simultaneously, ensuring the compactness of the casting material and improving the casting efficiency.

[0023] 2. The present invention controls the operation of the motor to drive the main shaft to rotate, and the main shaft drives the auxiliary rod to rotate through the connecting seat. Because the gear outside the auxiliary rod is meshed and connected with the gear ring, and the top of the auxiliary rod is connected to the connecting seat through the bearing seat, the auxiliary rod can rotate in the bearing seat. While the connecting seat drives the auxiliary rod and the gear to rotate, the auxiliary rod can rotate on its own, so that the main shaft and the auxiliary rod can respectively drive multiple blades to rotate and mix and stir the casting material in the box. The auxiliary rod can make a circular motion around the main shaft while rotating, so that the casting material can be mixed in multiple directions, thereby improving the mixing effect of the casting material. Moreover, the stirring work can be carried out continuously during the casting process to prevent the casting material from settling and affecting the casting quality.

[0045] As a further solution of the present invention, a booster 12 is installed on one side of the top of the box cover 2, and a connecting pipe 13 is installed at the bottom of the booster 12.

Because the end of the fixed rod 405 is fixed to the box body 1, it plays a role of supporting the box body 1, further improving the rotation stability of the box body 1.

[0049] A construction method for a ladle working layer casting device, the construction method comprising the following steps:

[0050] Before pouring, the ladle needs to be inspected to ensure that it is intact, and the casting material is selected according to the casting requirements of the ladle working layer. When pouring the outer ring working layer of the ladle, the casting material is 60-80mm carbon-free corundum spinel casting material. The casting material is added into the box 1 through the material pipe 3, and water is added in a prescribed proportion for stirring;

[0051] The motor 5 is controlled to work so as to drive the main shaft 701 to rotate, and the main shaft 701 drives the auxiliary rod 705 to rotate through the connecting seat 702. Since the auxiliary rod 705 is connected with a gear 704 on the outside, and the top of the auxiliary rod 705 is connected to the connecting seat 702 through the bearing seat 703, the auxiliary rod 705 can rotate in the bearing seat 703. Since the gear 704 is meshed with the gear ring 6 inside the box body 1, while the connecting seat 702 drives the auxiliary rod 705 and the gear 704 to rotate, the auxiliary rod 705 can rotate by itself, so that the main shaft 701 and the auxiliary rod 705 respectively drive the multiple blades 706 to rotate and mix and stir the casting material in the box body 1. The auxiliary rod 705 can make a circular motion around the main shaft 701 while rotating, so that the casting material can be mixed in multiple directions.

[0052] After the mixing of the casting material is completed, the push handle 403 in the support assembly 4 is pushed to drive the fixed frame 401 and the box body 1 to move, so that the universal wheel 402 at the bottom of the fixed frame 401 can roll on the ground, and the casting device is moved to the top of the ladle, so that the ladle is located inside the fixed frame 401. When casting the working layer of the ladle, the winding machine 101 is controlled to drive the rope drum 102 to rotate, and the rope drum 102 releases the four pull ropes 103, and the elastic force of the spring 117 is used to support the sliding sleeve 115, so that the sliding sleeve 115 drives the connecting rod 114 to move, and the connecting rod 114 drives the flexible tube 112 to move through the adjusting frame 111, so that the four flexible tubes 112 can move away from each other until The bottom end of the flexible tube 112 is located directly above the working layer of the ladle. The four electrically controlled valve tubes 113 are opened at the same time, so that the casting material inside the box body 1 can be discharged from the bottom end of the flexible tube 112 through the electrically controlled valve tube 113. The push handle 403 is held and rotated, and the push handle 403 drives the support ring seat 404 and the box body 1 to rotate through the fixed rod 405. Since the outside of the box body 1 is connected to the fixed frame 1 through the support bearing 406, it plays a role in supporting the box body 1, thereby improving the rotation stability of the box body 1. The box body 1 drives the winding assembly 10 at the bottom to rotate, so that the flexible tube 112 in the winding assembly 10 can revolve around the center of the ladle, so that the casting material can be filled into the working layer of the ladle from multiple directions at the same time;

[0053] During the pouring process, the vibrating rod can be inserted into the socket 118 in the adjustment frame 111, and the vibrating rod can be limited by the socket 118, so that the vibrating rod can be stably placed in the steel bar working layer, and the vibrating rod can be controlled to vibrate while pouring, thereby preventing the pouring material from hollowing, so that the pouring work and the vibrating work can be completed synchronously, ensuring the compactness of the pouring material and improving the pouring efficiency. When the pouring speed needs to be adjusted, the supercharger 12 on the top of the box cover 2 is controlled to work, and the supercharger 12 pressurizes the inside of the box body 1 through the connecting pipe 13, so as to increase the discharge speed of the electric control valve pipe 113;

[0054] After the pouring work is completed, the pouring device is removed, the working layer of the ladle is baked, dried and sintered, and after the mold is removed from the ladle, the ladle is baked at low temperature according to the heating curve. When the temperature reaches 200-300℃, it is baked for more than 24 hours.

9. A construction method for a ladle working layer casting device, according to a ladle working layer casting device according to any one of claims 1 to 8, characterized in that: The construction method comprises the following steps: Before pouring, the ladle needs to be inspected to ensure that it is intact, and the casting material is selected according to the casting requirements of the ladle working layer. When pouring the outer ring working layer of the ladle, the casting material is a 60-80mm carbon-free corundum spinel casting material. The casting material is added into the box (1) through the material pipe (3), and water is added in a prescribed proportion for stirring; The motor (5) is controlled to drive the main shaft (701) to rotate, and the main shaft (701) drives the auxiliary rod (705) to rotate through the connecting seat (702). Since the auxiliary rod (705) is connected to the outside with a gear (704), and the top end of the auxiliary rod (705) is connected to the connecting seat (702) through a bearing seat (703), the auxiliary rod (705) can rotate in the bearing seat (703). The connecting seat (702) is engaged with the gear ring (6) of the main shaft (701), and while the connecting seat (702) drives the auxiliary rod (705) and the gear (704) to rotate, the auxiliary rod (705) can rotate on its own, so that the main shaft (701) and the auxiliary rod (705) respectively drive the plurality of blades (706) to rotate and mix the casting material in the box body (1). The auxiliary rod (705) can make a circular motion around the main shaft (701) while rotating on its own, so that the casting material can be mixed in multiple directions; After the mixing of the casting material is completed, the push handle (403) in the support assembly (4) is pushed to drive the fixed frame (401) and the box (1) to move, so that the universal wheel (402) at the bottom of the fixed frame (401) can roll on the ground, and the casting device is moved to the top of the ladle, so that the ladle is located inside the fixed frame (401). When casting the working layer of the ladle, the winding machine (101) is controlled to drive the rope drum (102) to rotate, and the rope drum (102) releases the four pull ropes (103), and cooperates with the elastic force of the spring (117) to support the sliding sleeve (115), so that the sliding sleeve (115) drives the connecting rod (114) to move, and the connecting rod (114) drives the flexible tube (112) to move through the adjustment frame (111), so that the four flexible tubes (112) can move away from each other until the casting operation is carried out. The bottom end of the flexible tube (112) is located directly above the working layer of the steel ladle. The four electrically controlled valve tubes (113) are opened at the same time, so that the casting material inside the box body (1) can be discharged from the bottom end of the flexible tube (112) through the electrically controlled valve tube (113). The push handle (403) is held and rotated, and the push handle (403) drives the support ring seat (404) and the box body (1) to rotate through the fixed rod (405). Since the outside of the box body (1) is connected to the fixed frame (1) through the support bearing (406), it plays a role in supporting the box body (1), thereby improving the rotation stability of the box body (1). The box body (1) drives the winding assembly (10) at the bottom to rotate, so that the flexible tube (112) in the winding assembly (10) can revolve around the center of the steel ladle, so that the casting material can be filled into the working layer of the steel ladle from multiple directions at the same time; During the pouring process, the vibrating rod can be inserted into the socket (118) in the adjustment frame (111), and the vibrating rod can be limited by the socket (118), so that the vibrating rod can be stably placed in the steel bar working layer. The vibrating rod can be controlled to vibrate while pouring, thereby preventing the pouring material from hollowing, so that the pouring work and the vibrating work can be completed synchronously, ensuring the compactness of the pouring material and improving the pouring efficiency. When the pouring speed needs to be adjusted, the booster (12) on the top of the control box cover (2) is controlled to work, and the booster (12) increases the pressure inside the box body (1) through the connecting pipe (13), thereby increasing the discharge speed of the electric control valve pipe (113); After the pouring work is completed, the pouring device is removed, the working layer of the ladle is baked, dried and sintered, and after the mold is removed from the ladle, the ladle is baked at low temperature according to the heating curve. When the temperature reaches 200-300℃, it is baked for more than 24 hours.
