Description
Technical Field
The invention relates to a mounting tool of a converter oxygen lance nozzle, in particular to a top mounting device of the converter oxygen lance nozzle.
Background
The oxygen top-blown converter steelmaking of China starts from 1962, and has more than 22 types of oxygen lances in China through practical development of 60 years, and the basic form is mainly a water-cooled oxygen lance structure form. The gun body is formed by nesting three concentric circular tubes, and is formed by oxygen transmission of an inner tube, and annular cracks between the three layers of tubes are used for cooling water to enter and return to a channel.
The nozzle is used as an important component of the oxygen lance, the quality of the nozzle determines the performance quality of the oxygen lance, the design parameters of the nozzle must meet the requirements of smelting technology, and the final work of maintaining and manufacturing the oxygen lance is to install the nozzle.
At present, an O-shaped rubber sealing structure is adopted for a converter nozzle (the application of the sealing structure on an oxygen lance starts in the 80 th century, and a double-flow four-layer steel pipe oxygen lance designed for a 120T converter in a steel climbing mill is adopted for the first time, and then the sealing structure is simple in structure, excellent in performance and popularized nationally) as shown in fig. 1.
Because the fit dimensional tolerance between the oxygen pipe of the spray head and the oxygen seal sliding section is 0.1-0.2 mm, the roughness is below 32. The sealing O-shaped rubber ring of the spray head is in certain tight fit with the sliding section of the oxygen pipe, and the O-shaped ring can meet the sealing requirement only by being compressed by 1-2 mm. This makes it possible to install the nozzle with a relatively high pressure (about 500-2000KG actually measured) to press the sealing section into the oxygen tube (outer tube of the lance) for effective sealing. The mode that adopts long thick stick striking to install among the prior art, and the operation risk is big, and intensity of labour is high, and striking can damage the red copper surface and the welded seam structure of shower nozzle simultaneously, has certain equipment to use the risk.
From the above, it can be seen that: the operating mode of the striking mode of the long bar in the prior art has at least the following disadvantages:
1. 4 persons are required to perform the operation in coordination, about 2 hours.
