Abstract
Description
Technical Field
[0001] This utility model relates to pneumatic slag breaking technology, and more particularly to a pneumatic slag breaking steel rod device. Background Technology
[0002] Currently, the aluminothermic reduction reaction method used in our alloy production results in a certain amount of slag in some alloy molten materials after the reaction. Although the density of the slag is less than that of the alloy molten material, as the top of the alloy molten material solidifies, some of the slag will remain in the alloy, affecting the quality of the alloy ingot and reducing product quality. Utility Model Content
[0003] The purpose of this invention is to address the problem of product quality degradation caused by the incomplete floating of solidified slag on the surface of the alloy liquid after reaction. This invention proposes a pneumatic slag-breaking steel rod device. The device is simple in composition, reasonable in structure, and convenient to operate. It can create holes on the surface of the alloy liquid to help the slag inside the alloy liquid float to the surface, effectively improving the quality of the alloy ingot.
[0004] It should be noted that, in this utility model, unless otherwise specified, the specific meaning of "comprising" in relation to composition and description includes both open-ended meanings such as "comprising," "including," etc., and closed-ended meanings such as "composed of," "consisting of," etc., and similar meanings.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pneumatic slag-breaking steel rod device, comprising a platform cart, a slag-breaking chamber, a slag-breaking rod, a positioning sleeve, a cylinder, and a cylinder fixing frame. The slag-breaking chamber is provided with a chamber door, and the platform cart can enter and exit the slag-breaking chamber through the chamber door. The platform cart is used to place the crucible mold. A cylinder fixing frame is provided above the slag-breaking chamber, and the cylinder body of the cylinder is set inside the cylinder fixing frame. The slag-breaking rod is coaxially mounted on the piston rod of the cylinder. The positioning sleeve is welded to the center of the steel structure at the top of the slag-breaking chamber. The slag-breaking rod can pass through the positioning sleeve into the slag-breaking chamber and can penetrate deep into the crucible mold. The crucible mold contains alloy liquid that has not completely solidified after the reaction.
[0006] Furthermore, asbestos is installed on all four walls and the top of the slag-breaking chamber to insulate against heat.
[0007] Furthermore, the cylinder mounting bracket has two layers: the lower layer is used to mount the cylinder, and the upper layer is used to mount a hand chain hoist when repairing or replacing the cylinder.
[0008] Furthermore, a single-ear base is fixed to the tail of the cylinder body, and a double-ear base is fixed on the cylinder mounting bracket. The single-ear base and the double-ear base are connected by a pin to fix the cylinder to the cylinder mounting bracket.
[0009] Furthermore, the slag-breaking chisel includes a first internal threaded flange, a second internal threaded flange, an adapter rod, and a slag-breaking steel chisel connected in sequence, with the first internal threaded flange connected to the lower end of the cylinder piston rod.
[0010] Furthermore, the first and second internal threaded flanges are fixed by bolts; the length of the adapter rod should meet the following requirements: when the cylinder retracts, the lower part is inside the slag breaking chamber and above the crucible mold; when the cylinder extends, it can penetrate into the incompletely solidified alloy liquid inside the crucible mold; the lower end of the adapter rod is provided with an internal thread that mates with the external thread at the upper end of the slag breaking steel rod. During installation, the external thread of the slag breaking steel rod is screwed into the internal thread of the adapter rod and tightened in place.
[0011] Furthermore, the positioning sleeve includes a first inner threaded sleeve, a second inner threaded sleeve, an outer threaded extension tube, a ring, a first pressure cap, and a second pressure cap. The first inner threaded sleeve and the second inner threaded sleeve are respectively threadedly fitted at the upper and lower ends of the outer threaded extension tube. The outer side of the ring is welded to the roof steel structure of the slag crushing chamber, and the inner side is welded to the outer wall of the first inner threaded sleeve. The first pressure cap and the second pressure cap are respectively disposed on the inner walls of the first inner threaded sleeve and the second inner threaded sleeve.
[0012] Furthermore, a PTFE packing is provided in the gap between the first pressure cap and the inner wall of the first inner threaded sleeve, and a PTFE packing is provided in the gap between the second pressure cap and the inner wall of the second inner threaded sleeve, for positioning and dust prevention during slag breaking drill rod operation.
[0013] Furthermore, the top of the slag breaking chamber is also equipped with a heat dissipation vent, which is connected to a dust collector via a pipe to discharge the heat emitted during the solidification of the alloy liquid.
[0014] Furthermore, the floor of the slag breaking chamber is provided with a positioning structure, including but not limited to positioning buckles, for positioning and fixing the platform vehicle, thereby realizing the positioning of the crucible mold.
[0015] Furthermore, the pneumatic slag-breaking steel rod device also includes a control system (including but not limited to an electrical control program). Under the drive of the control system, the cylinder piston rod reciprocates to insert the slag-breaking steel rod into the alloy liquid in the crucible mold to a suitable depth, and repeatedly breaks the slag.
[0016] The working process of the pneumatic slag-breaking rod is as follows: A platform vehicle transports the reacted crucible mold to a designated position within the slag-breaking chamber, ensuring the slag-breaking rod is aligned with the center of the crucible mold. The slag-breaking chamber door is then closed, and the operator activates the slag-breaking rod switch, driving the cylinder to reciprocate. During this process, the rod at the tip continuously penetrates the surface of the molten alloy, causing the internal slag to float to the surface. This operation continues until the molten alloy solidifies, and until the rod can no longer penetrate the surface.
[0017] This utility model of pneumatic slag breaking steel rod device has the following advantages compared with the prior art:
[0018] 1) The pneumatic slag breaking steel rod device of this utility model has a simple and reasonable structure. The key components such as the slag breaking rod and positioning sleeve adopt a detachable modular design (such as flange connection and threaded connection), which is convenient for disassembly and replacement.
[0019] 2) The cylinder fixing frame of the pneumatic slag breaking steel rod device of this utility model is specially designed with a two-layer structure. The upper layer is specially used to fix the hand chain hoist during maintenance, which greatly facilitates the replacement and maintenance of the cylinder and reduces the intensity and difficulty of maintenance work.
[0020] 3) The pneumatic slag-breaking steel rod device of this utility model is suitable for slag breaking of alloy liquid that has not solidified after reaction. The device uses a pneumatically driven slag-breaking steel rod to repeatedly pierce the surface of the alloy liquid before it solidifies, effectively breaking the solidified shell and creating a channel for the internal slag material to float to the surface, thereby reducing slag inclusions in the alloy ingot and significantly improving the quality of the final product.
[0021] 4) The slag-breaking chamber of this utility model's pneumatic slag-breaking steel rod device is insulated with asbestos on all four walls and the top, ensuring the safety of outdoor equipment and personnel. The heat dissipation vents on the top can promptly discharge the heat and fumes emitted during the solidification of the alloy liquid, improving the working environment.
[0022] This utility model of pneumatic slag breaking steel rod has good application prospects and large-scale promotion potential in the field of alloy production. Attached Figure Description
