The third guide wheel provided reduces the friction between the guide block and the billet, ensuring the integrity of the billet as much as possible. The inclined setting of the third guide wheel increases the friction between the third guide wheel and the first traction member, thereby improving the stability of the first traction member.

[0051] A casting process, using the vertical semi-continuous casting machine described above, the casting process comprises:

[0052] Ingot casting: Move the guide vehicle and the carrier vehicle to the bottom of the crystallizer, then start the first traction member to drive the starter head to move upward, and the molten steel falls onto the starter head through the crystallizer. At the same time, start the first traction member to drive the starter head and the ingot casting to move downward until the starter head contacts the placement seat;

[0053] Guiding: When the first traction member drives the ingot starter to rise, the sixth driving member is started to drive the guide block to move in the direction close to the first traction member; when the first traction member and the billet are lowered, the first driving member and the second driving member are started, the first driving member drives the first guide wheel to move in the direction close to the billet, and the second driving member drives the second guide wheel to move in the direction close to the billet;

[0058] When making ingots, first move the carrier to the bottom of the crystallizer, then start the first traction member to drive the ingot head upward; after the ingot head moves to the corresponding position, pour molten steel into the crystallizer, and the ingot falls onto the ingot head. At the same time, start the first traction member to drive the ingot head downward until it moves to the corresponding position; then stop pouring molten steel into the crystallizer, and finally use the carrier to drive the ingot to move to the ingot slow cooling zone, where the ingot is stored for a period of time. Compared with the existing vertical continuous casting machine, this design greatly reduces the height, which means that the construction volume and equipment investment are greatly reduced;

[0059] The first guide assembly is not only convenient for guiding the billets with the same diameter, reducing the possibility of the billets shifting during the descent process, but also convenient for guiding the billets with different diameters, thus improving the diversity of use;

[0060] After the billet moves to the position of the two push rods, the eighth driving member is started to drive the push rod to move in the direction close to the billet until the push rod abuts against the billet. After the insertion holes on the placement seat and the ingot head are aligned, the seventh driving member is started, and the seventh driving member is inserted into the placement seat and the ingot head to achieve the connection between the placement seat and the ingot head, and then the billet is lifted by the crane. At this time, since the placement seat and the ingot head remain connected, only the billet and the second traction member are lifted upward. This design reduces the separation of the ingot head and the placement seat during the movement of the billet, which leads to the need to re-place the ingot head and adjust the ingot head in the later stage, thereby improving the convenience of operation.

[0068] Reference Figure 1 The present application provides a vertical semi-continuous casting machine, comprising a ladle turret 19, a tundish car 20, a crystallizer 21, and a car-type billet conveying device arranged in sequence from top to bottom. When casting billets, the molten steel flows downward into the tundish car 20 through the ladle turret 19, and then flows downward into the crystallizer 21 to gradually solidify the molten steel into billets of required specifications and shapes; the formed billets continue to fall downward and fall into the car-type billet conveying device below the crystallizer 21; after billets of required specifications and shapes are formed in the car-type billet conveying device, the casting is stopped; finally, the billets are transported to the billet slow cooling zone for storage by the car-type billet conveying device.

Compared with the existing vertical semi-continuous casting machine, this design greatly reduces the height, which means that the construction volume is greatly reduced and the equipment investment is greatly reduced.

[0072] Reference Figure 1 In actual operation, the height of the billet is generally more than 10m. If the billet is transported only by the carrier vehicle 1, the billet is prone to collapse.

[0075] When the formed billet descends, the first driving member 73 is started to drive the first bending rod 72 toward the billet until it abuts against the billet. This design is not only convenient for guiding billets with the same diameter and reducing the possibility of the billets shifting during the descent, but also convenient for guiding billets with different diameters, thereby increasing the diversity of use.

[0078] When the formed ingot is about to be lowered onto the carrier vehicle 1, the second driving member 83 is started to drive the second bending rod 82 toward the ingot until it abuts against the ingot. Such a design is not only convenient for guiding ingots with the same diameter and reducing the possibility of deviation of the ingots during the descending process, but also convenient for guiding ingots with different diameters, thereby increasing the diversity of use.

[0079] Reference Figure 4 , optionally, the second support rod 81 is vertically arranged; the second guide assembly 8 also includes a second guide wheel 85, and the second guide wheel 85 is rotatably connected to a position at one end of the second bending rod 82 away from the second driving member 83.

[0080] Since the height of the ingot is generally high, the push rod in the first pulling member 4 needs to be raised to a high height during the actual operation. In this case, the push rod in the first pulling member 4 is prone to shaking. Figure 5 For this purpose, the car-type casting billet conveying device further comprises a third guide assembly 9, two third guide assemblies 9 are provided, and the two third guide assemblies 9 are arranged along the ingot starter 3 (refer to Figure 2) are symmetrically arranged along the central axis of the guide wheel 1. The third guide assembly 9 includes a guide block 91, a first light rod 92 and a sixth drive member 93. The guide block 91 is arranged on the carrier 1; there are two first light rods 92, which are respectively arranged at the two ends of the guide block 91, and the two first light rods 92 are fixedly connected to the carrier 1. The guide block 91 is sleeved on the first light rod 92 and is slidably connected to the first light rod 92. The sixth drive member 93 is arranged at one end of the guide block 91 away from the ingot head 3, and the movement direction of the sixth drive member 93 is the same as the extension direction of the first light rod 92; in the embodiment of the present application, the sixth drive member 93 adopts a hydraulic cylinder, and the push rod in the hydraulic cylinder is fixedly connected to the guide block 91. Of course, in other examples, the sixth drive member 93 can also adopt a cylinder.

[0081] During the ascending process of the first traction member 4 , the sixth driving member 93 is activated to drive the guide block 91 to move toward the first traction member 4 until the guide block 91 abuts against the push rod in the first traction member 4 .

[0082] Reference Figure 5 Optionally, the guide block 91 is horizontally arranged, and the first polished rod 92 is horizontally arranged. The third guide assembly 9 further includes at least one third guide wheel 94, which is arranged at a position of the guide block 91 close to the end surface of the ingot starter 3, and the third guide wheel 94 is rotatably connected to the guide block 91. In the embodiment of the present application, two third guide wheels 94 are provided, and are symmetrically arranged along the center line of the guide block 91.

[0083] Reference Figure 5 Optionally, the third guide wheel 94 is tilted from the direction away from the starter head 3 to the direction close to the axis of the starter head 3. Such a design improves the friction between the third guide wheel 94 and the first traction member 4, thereby improving the stability of the first traction member 4.

[0084] In order to realize the detachable connection between the first pulling member 4 and the ingot starter 3, it is convenient to separate the ingot starter 3 from the first pulling member 4. Figure 2 For this purpose, the vehicle-type casting conveying device further includes a locking assembly 10, which includes a second locking pin 101. The second locking pin 101 penetrates the starter head 3 and the first traction member 4, and is slidably connected with the starter head 3 and the first traction member 4; the starter head 3 and the first traction member 4 are provided with a plug hole for the second locking pin 101 to be inserted. When making castings, the second locking pin 101 is inserted into the starter head 3 and the first traction member 4 to connect the starter head 3 and the first traction member 4; after the casting is made, the second locking pin 101 is pulled outward from the starter head 3 and the first traction member 4, so that the first traction member 4 is separated from the starter head 3, so as to facilitate the moving of the casting to the casting slow cooling zone for storage.

[0085] Reference Figure 2Furthermore, the locking assembly 10 also includes a fourth driving member 102 and a plurality of pin-releasing racks 103. The fourth driving member 102 is arranged on one side of the ingot starter 3, and the movement direction of the fourth driving member 102 is colinear with the extension line of the axis of the second locking pin 101; in the embodiment of the present application, the fourth driving member 102 adopts a hydraulic cylinder, and the push rod in the hydraulic cylinder is coaxial with the second locking pin 101. The pin-releasing rack 103 is arranged on the other side of the ingot starter 3, and the pin-releasing rack 103 is fixedly connected to the carrier 1. The pin-releasing rack 103 is provided with a placement hole for placing the second locking pin 101, and the extension line of the axis of the second locking pin 101 is colinear with the extension line of the axis of the plurality of placement holes. After the production of the ingot is completed, the fourth driving member 102 is started to push the second locking pin 101 out of the ingot starter 3 and the first traction member 4 until it moves into the placement hole. When the ingot is produced, the ingot placed in the placement hole is inserted into the ingot starter 3 and the first traction member 4.

[0086] Reference Figure 2 Furthermore, the locking assembly 10 includes a fifth driving member 104. The fifth driving member 104 is disposed on a side of the pin-releasing frame 103 away from the starter head 3, and the movement direction of the fifth driving member 104 is colinear with the extension lines of the axes of the multiple placement holes. Such a design reduces the possibility of manual intervention and further improves the convenience of operation.

[0087] Reference Figure 2 and Figure 5 , so that the ingot can descend more stably. The car-type ingot conveying device also includes a second traction member 11, and the second traction member 11 includes an embedded column 111 and a traction column 112. The embedded column 111 is embedded in the ingot head 3, and is detachably connected to the ingot head 3. The embedded column 111 is coaxially arranged with the ingot head 3; the traction column 112 is fixedly connected to one end of the embedded column 111 close to the support frame 5, and at least one traction column 112 is provided. In the embodiment of the present application, four traction columns 112 are provided, and are evenly distributed on the end surface of the embedded column 111 close to the support frame 5.

[0088] When making the ingot, after the first traction member 4 drives the ingot starter 3 and the second traction member 11 to rise to the corresponding position, the molten steel flows downward from the crystallizer 21 to the second traction member 11 until the traction column 112 is completely wrapped; then the first traction member 4 is started to drive the ingot starter 3 and the second traction member 11 to move downward until they drop to the limit position. The second traction member 11 not only improves the connection strength between the formed ingot and the ingot starter 3, but also enables the formed ingot and the ingot starter 3 to be connected without contact. After the specifications of the ingot reach the corresponding specifications, stop pouring molten steel into the crystallizer 21, and then separate the second traction member 11 from the ingot starter 3, so that the ingot and the ingot starter 3 are separated; such a design facilitates the secondary use of the ingot starter 3, thereby achieving the effect of reducing the production cost.

[0089] Reference Figure 2 and Figure 5 Optionally, the traction column 112 is tilted from the direction close to the embedded column 111 to the direction away from the axis of the embedded column 111. Such a design improves the connection strength between the billet and the traction column 112, thereby facilitating a smoother downward movement of the formed billet.

[0090] Reference Figure 2 In order to make the starter head 3 and the embedding column 111 detachably connected, the car-type ingot conveying device further includes a fixing assembly 12, which includes a first locking pin 121 and a third driving member 122. The first locking pin 121 penetrates the placement seat 2, the starter head 3 and the embedding column 111, and is slidably connected with the placement seat 2, the starter head 3 and the embedding column 111; the placement seat 2, the starter head 3 and the embedding column 111 are provided with a plug hole for the first locking pin 121 to be inserted. There are two third driving members 122, which are respectively arranged on both sides of the placement seat 2; the movement directions of the two third driving members 122 are both colinear with the extension line of the axis of the first locking pin 121; one of the two third driving members 122 is arranged in the placement seat 2; in the embodiment of the present application, the third driving member 122 adopts a hydraulic cylinder, and the push rod in the hydraulic cylinder is coaxial with the first locking pin 121. Of course, in other examples, the third driving member 122 can also adopt a cylinder.

[0091] After the ingot is made, first start a third driving member 122 to push the first locking pin 121 outward from the ingot starter head 3 and the embedded column 111, and then use the ingot clamp to pull the ingot, the embedded column 111 and the traction column 112 outward from the ingot starter head 3; when making the ingot, start another third driving member 122 to push the first locking pin 121 into the ingot starter head 3 and the embedded column 111, so that the ingot starter head 3 is connected with the embedded column 111, and then start the first traction member 4 to drive the ingot starter head 3, the embedded column 111 and the traction column 112 to move upward.

At this time, the eighth driving member 134 is started, and the eighth driving member 134 drives the push rod 132 to move in the direction close to the billet until the push rod 132 abuts against the billet. At this time, the seventh driving member 14 is started, and the push rod in the seventh driving member 14 is inserted into the placement seat 2 and collides with the ingot starter 3. Through the impact of the seventh driving member 14, the ingot starter 3 will be separated from the billet, and finally the billet can be lifted by the billet clamp. Such a design facilitates the separation of the ingot starter 3 from the billet, reduces the workload of manual separation, and improves the convenience of operation.
