At present, the mud sleeve is usually made manually, which is not only time-consuming and laborious, but also affects the iron removal of the blast furnace and even the operation inside the furnace. Therefore, how to make a high-quality mud sleeve in a short time, shorten the production time of the taphole mud sleeve, and ensure the timely discharge of slag and iron is an urgent problem for the current personnel in this field.

[0027] The technical solution of this embodiment will be further described below with reference to the drawings and through specific embodiments.

[0028] As Figures 1 - 3 shown, this embodiment provides a tool for making the mud sleeve of the blast furnace taphole, including a disc 10, a round steel 20, a round steel rod 50, and a limit plate 60. The round steel 20 and the round steel rod 50 are respectively arranged on both sides of the disc 10 and are in communication with each other. The round steel rod 50 can be inserted into the gun mud of the hydraulic gun head 100, and the round steel 20 can abut against the blast furnace taphole and convey the gun mud to the blast furnace taphole. One end of the limit plate 60 is fixed to the disc 10, and the other end can be buckled on the hydraulic gun head 100.

[0029] Specifically, in this embodiment, the primary forming of the mud sleeve can be achieved without secondary correction, which avoids damaging the new mud sleeve, improves the production quality, effectively improves the work efficiency, avoids time-consuming and laborious manual operations, and does not affect the operation of the blast furnace for iron removal. Further, by inserting the round steel rod 50 into the gunite, the round steel 20 can abut against the iron notch of the blast furnace, ensuring that the gunite is stably conveyed to the iron notch of the blast furnace, and thus realizing the primary forming production of the mud sleeve. Further, in this embodiment, the limiting plate 60 is buckled on the hydraulic gun head 100 to ensure the stable placement of the entire tool on the hydraulic gun head 100, avoiding falling off during use to ensure the operation quality and efficiency.

[0030] The following describes the specific structure of the tool for making the mud sleeve at the iron notch of the blast furnace in this embodiment.

Specifically, the round steel 20 and the ring 30 are respectively arranged on both sides of the disc 10, the round steel rod 50 and the ring 30 are arranged on the same side, and the round steel rod 50 can be inserted into the gunite of the hydraulic gun head 100. Further, the rib plates 40 are respectively connected to the disc 10 and the round steel rod 50 to improve the connection strength between the two, and the limiting plate 60 is fixed on the disc 10 to lock the entire device on the hydraulic gun head 100 to prevent falling off.

[0032] Combined with Figures 1 - 3 shown, in this embodiment, the diameter of the disc 10 is set to 280 mm and the thickness is set to 10 mm. In other embodiments, the corresponding dimensions can be set as needed. Further, the round steel 20 and the round steel rod 50 are located on both sides of the disc 10, and their interiors are interconnected, that is, the inner cavity of the round steel rod 50, the through hole provided on the disc 10, and the inner cavity of the round steel 20 are interconnected. In this way, when the round steel rod 50 is inserted into the gunite of the hydraulic gun head 100, the round steel 20 can abut against the iron notch of the blast furnace, and under the power action of the hydraulic gun head 100, the gunite is conveyed to the iron notch of the blast furnace, thereby completing the production of the mud sleeve. Exemplarily, the round steel 20 and the round steel rod 50 are both fixed to the disc 10 by welding to ensure the stable connection of the three. Further, in this embodiment, the diameter of the round steel 20 is set to 50 mm and the height is set to 20 mm, and the length of the round steel rod 50 is set to 200 mm and the diameter is set to 20 mm. In other embodiments, their corresponding dimensions can also be adjusted as needed.

Thus, the hydraulic gun head 100 can be positioned through the setting of the circular ring 30 to ensure the accuracy of the connection between the hydraulic gun head 100 and the tool for making the mud sleeve of the blast furnace tuyere, and improve the installation efficiency of the two. Correspondingly, in this embodiment, the inner diameter of the circular ring 30 is set to 140 mm, the outer diameter is set to 150 mm, and the thickness is 10 mm. Exemplarily, the circular ring 30 is fixed to the disk 10 by welding to improve the mechanical strength of the entire device.

Optionally, a plurality of rib plates 40 are provided, and the plurality of rib plates 40 are evenly distributed around the center line of the round steel rod 50 to ensure the stable connection between the disk 10 and the round steel rod 50. Specifically, the number and position of the relief grooves and the rib plates 40 are set in one-to-one correspondence, and in this embodiment, the length of the side of the rib plate 40 connected to the side of the disk 10 is less than or equal to the ring diameter of the circular ring 30, that is, the length of this side of the rib plate 40 is less than or equal to the length of the relief groove, so as to avoid interference of the rib plate 40 with the hydraulic gun head 100 when the hydraulic gun head 100 is positioned on the circular ring 30. Exemplarily, in other embodiments, the rib plate 40 can also be directly connected to the circular ring 30 to avoid setting the relief groove. Thus, the circular ring 30 and the disk 10 can be connected by welding, and still the overall structure of the circular ring 30 and the disk 10 can be ensured, and a stable connection can be achieved between the circular ring 30 and the disk 10 and the round steel rod 50 through the rib plate 40. The specific setting method can be set according to the needs of the operator and will not be elaborated here. Exemplarily, the thickness of the rib plate 40 is set to 5 mm, and in this embodiment, four rib plates 40 are provided and are evenly distributed on the outer side of the round steel rod 50.

[0035] Combined Figure 2 and Figure 3 As shown, in this embodiment, one end of the limiting plate 60 is fixed to the disk 10, and the other end can be buckled on the hydraulic gun head 100, so as to limit and fix the entire device on the hydraulic gun head 100, avoid falling off and improve the connection stability. Optionally, in this embodiment, the limiting plate 60 is set as an L-shaped structure, and the short side of the limiting plate 60 can press against the rear of the hydraulic gun head 100, so as to lock the position of the hydraulic gun head 100 and avoid the tool falling off during operation. Exemplarily, in this embodiment, two limiting plates 60 are provided, and the two limiting plates 60 are oppositely arranged at the edge of the disk 10, so as to ensure a stable connection with the hydraulic gun head 100 after the positioning of the circular ring 30. Exemplarily, the thickness of the limiting plate 60 is set to 5 mm.

[0036] Working process: First, prepare the casting material for the taphole mud jacket and evenly apply it above the taphole; then push out a part of the mud in the hydraulic gun head 100, insert the round steel rod 50 into the mud until the port of the hydraulic gun head 100 can be sleeved on the outside of the ring 30 to limit the position of the hydraulic gun head 100; at the same time, fix the two limit plates 60 behind the hydraulic gun head 100 respectively to further lock its position; finally, start the hydraulic gun head 100 so that the round steel 20 can abut against the blast furnace taphole and collide with it to realize the pressing of the mud jacket; finally, after the mud jacket is made, retract the hydraulic gun head 100 to its original position to complete the production of the blast furnace taphole mud jacket.
