Description

Technical Field

[0001] The utility model relates to the technical field of rectifier bridges, in particular to a long-life steel outlet. Background Art

[0002] The converter tapping port is the only channel for molten steel to enter the ladle from the converter. During tapping, the converter tapping port needs to withstand the friction, erosion and oxidation corrosion of high-temperature molten steel and slag, resulting in a very short service life of the tapping port. The current tapping port is equipped with a tapping port sleeve. The so-called tapping port sleeve is a tubular refractory made of magnesium-carbon refractory. When in use, it is placed in the tapping port seat brick and the joint is sealed with refractory mud. During tapping, molten steel flows into the ladle along the tapping port. When the tapping port is severely eroded, it must be replaced.

[0003] Patent network publication number CN216473308U discloses a new type of converter steel tapping port. When in use, cooling water is introduced through the water inlet and discharged through the water outlet. Cooling water can be introduced into the cooling water channel, which is conducive to rapid cooling after steel tapping is completed, avoiding heat accumulation and damaging the internal structure, and extending the internal life of the steel tapping port. During the actual use of the steel tapping port, in addition to cooling the steel tapping port, it is also necessary to prevent molten steel splashing to cause damage to personnel or equipment. However, this device lacks the function of preventing molten steel splashing. Utility Model Content
