Embodiment Construction
[0011] like figure 1 Shown: a steel ladle protection tube, including a tube body, fastening bolts, and bolt gaskets. The tube body includes a fixed area and a liquid flow area. Tight fastening bolts, bolt gaskets are fixed on the fastening bolt heads inside the pipe body, the inner cavity of the liquid flow area is a barrel-shaped structure with a small top and a large bottom, and the fixed area and the liquid flow area are connected. The injection through hole.
[0012] Further, there are more than two fastening bolts. Multiple bolts make the fixation between the device and the lower port of the ladle more firm.
[0013] It further includes a top cover, the top cover is located above the tube body and matches the upper opening of the tube body fixing area, and the center part of the top cover has a top cover through hole matching the size of the liquid injection through hole and coaxial. The top cover makes it a sealed space to further ensure that the molten steel does not...

The invention provides a steel ladle protective pipe. The steel ladle protective pipe comprises a pipe body, fastening bolts and bolt gaskets. The pipe body comprises a fixing area and a liquid flowing area. The fastening bolts capable of being screwed inwards are evenly distributed on the periphery of the fixing area of the pipe body, and the bolt gaskets are fixed to the parts, located inside the pipe body, of the fastening bolts. The inner cavity of the liquid flowing area is of a big-end-down cylindrical structure, and the fixing area and the liquid flowing area are provided with communicated liquid injection through holes. The number of the fastening bolts is two or more. The steel ladle protective pipe further comprises a top cover located on the upper portion of the pipe body and matched with an upper opening of the fixing area of the pipe body, and the inner cavity of the liquid flowing area inclines outwards by 15-20 degrees. The steel ladle protective pipe has the advantages and beneficial effects that the upper portion of the steel ladle protective pipe is fixed in a bolt fastening mode, use of mechanical backing rings is reduced, and fixation is more convenient and simpler. The protective pipe is provided with the big-end-down inclined pipe body, so that molten steel descends in a divided mode in the descending process, and linear fixed point impact of multiple tundishes is reduced.
Description
technical field [0001] The invention relates to the field of casting, in particular to a ladle protection tube Background technique [0002] In the process of casting molten steel, when the molten steel enters the tundish from the ladle, in order to prevent the molten steel from contacting with the air, the molten steel protection tube is generally used for sealing protection, but the general molten steel protection sleeve is fixed by a mechanical support ring, which is difficult to operate , and the protective pipe is a straight-through pipe, the molten steel is likely to cause impact on the tundish during the process of going into the well, affecting the production process. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a ladle protection tube, including a tube body, fastening bolts, bolt gaskets, the tube body includes a fixed area and a liquid flow area, and the fi...
