The influence of the oxygen lance on the blowing is realized through the interaction of the oxygen jet stream and the molten pool, and the influence mainly depends on the velocity and the distribution of the jet stream when reaching the surface of the molten pool, so the optimization of various process parameters of the oxygen lance nozzle and the optimization design of the structure are very important. The application field of the oxygen lance is mainly applied to the steel industry, the metallurgy industry and the like.
The oxygen lance comprises oxygen, water inlet and water return pipes, three pipes correspond to an interface respectively and converge the oxygen lance body again, the three interface connection modes adopt flange connection, in the use process, because of long-term external force, some interface bent pipes deform, the oxygen lance cannot be centered after being installed, the difficulty and time for replacing the oxygen lance are increased, even the situation of repeated replacing and robbing occurs, and certain influence is brought to production.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel oxygen rifle off-line calibration device to propose the oxygen rifle in solving above-mentioned background art and by oxygen, intake, the wet return is constituteed, three root canals correspond an interface respectively, collect the oxygen rifle body again, three interface connection mode adopts flange joint, in the use, because long-term exogenic action, lead to some interface return bends to warp, unable centering after the oxygen rifle installation, the degree of difficulty and the time that the oxygen rifle was changed have also been increased, the repeated condition of robbing of trading appears even, bring the problem of certain influence for production.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel oxygen rifle off-line check-up device, includes the bottom plate, the upper end welding of bottom plate has the support frame, from the top down has inlet tube check-up flange, oxygen pipe check-up flange and outlet pipe check-up flange to welding in proper order on the support frame, all be connected with companion flange on inlet tube check-up flange, oxygen pipe check-up flange and the outlet pipe check-up flange, it is three be connected with the oxygen inlet pipe, inlet tube and the outlet pipe of oxygen rifle on companion flange respectively.
Preferably, the oxygen inlet pipe, the water inlet pipe and the water outlet pipe are respectively in one-to-one correspondence with the oxygen pipe check flange, the water inlet pipe check flange and the water outlet pipe check flange.
Preferably, both ends of the companion flange are connected with metal hoses.
Preferably, the oxygen inlet pipe, the water inlet pipe and the water outlet pipe of the oxygen lance comprise three concentric pipelines with different diameters.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the device is characterized in that three flange ports of a water inlet pipe check flange, an oxygen pipe check flange and a water outlet pipe check flange are welded on a support frame, the three flange ports can be aligned off line, the three flange ports and the support frame are fixed through a bottom plate and kept immovable, when the flanges have the problems of opening or misalignment, the bent pipe of the oxygen gun is deformed, the online use is avoided, the oxygen gun can be directly aligned to find whether the bent pipe of the oxygen gun is deformed, the online use of the oxygen gun with the deformed bent pipe is avoided, the replacement time is influenced, the management of the oxygen gun can be promoted, the optimization of a table tent tracking and replacement scheme can be well done for the oxygen gun with small deformation, guide suggestions are provided for replacement personnel, and the replacement errors are avoided;
2. directly not letting the oxygen rifle that warp greatly go on the line, avoiding the unable installation of oxygen rifle after going on the line to trade the rifle again and cause maintenance delay and influence production, this novel oxygen rifle off-line calibration equipment can the off-line carry out the centering to three flange interface, can discover whether the oxygen rifle return bend has the deformation, avoids changing and receives the influence, can promote the management to the oxygen rifle, guarantees production efficiency.
