Metal hose is linked with oxygen tank and cooling water pipeline respectively.
When oxygen top blown converter steel making produces, oxygen rifle is inserted in the molten steel of converter, anti-by the oxidation of oxygen
Should, play the effect of de-carbon and intensification, owing to oxygen rifle contacts high-temperature molten steel, in smelting process, usually can
Because of oxygen rifle leak, dry slag, the reason such as flexural deformation cannot normally use, and need to change in time oxygen rifle；Change
Oxygen rifle will dismantle and install the high-strength bolt connected on oxygen and cooling water metal hose flange, due to often
On root oxygen rifle, the position of related features between three bend pipe flanges is the most different, and will be to oxygen rifle during installing
Carrying out centering, i.e. the oxygen rifle perpendicularity of guarantee more than 20 meter long is in technique Measurement Allowance, and this is just to three
The mounting technology of group bolt proposes the highest requirement, once nut can not be screwed into the end during fastening bolt,
Will according to diagonal angle in pairs, gradually keep oxygen rifle position by stages while the fastening of tentative carrying out is adjusted
Whole, its highly difficult adjustment process causes this work time consuming, even if skilled operation teams and groups lead to
Often it is also required to about six hours, time-consuming takes a lot of work.
Summary of the invention
