Abstract
The invention discloses a method for installing and centering an oxygen lance as well as a vaporized flue and a converter mouth. The method comprises the following steps of: installing a laser emitting device at the center of the converter mouth; adjusting the direction of a laser beam so as to enable the laser beam to be perpendicular to a horizontal plane; installing a flue terminal target; covering an opening at the flue terminal with a semi-transparent thin film to form the flue terminal target, and labeling the position at the center of the flue terminal on the flue terminal target; adjusting the position of the flue terminal so as to enable the laser beam to penetrate through the center of the flue terminal target; labeling the center position of an oxygen lance inserting mouth on an oxygen lance inserting mouth target; adjusting the position of the oxygen lance inserting mouth so as to enable the laser beam to penetrate through the center of the oxygen lance inserting mouth target; centering the oxygen lance; adjusting the position of the oxygen lance so as to enable the laser beam to be dead against the center of the front end of the oxygen lance. By using the method for installing and centering the oxygen lance as well as the vaporized flue and the converter mouth, the labor intensity of installing workers can be lightened, the installing accuracy can be enhanced, the installing speed can be quickened, the installing engineering cost can be lowered, and the installing efficiency can be improved.
Description
Technical field
The present invention relates to the installation method of converter in metallurgical equipment, specifically, relate to the installation centering method of a kind of oxygen rifle and evaporated flue and converter mouth.
Background technology
Metallurgical equipment requires converter evaporated flue end center, oxygen rifle, oxygen rifle insert port center and 4, converter mouth center being aligned in installing.On-the-spot general the employing hung steel wire, and the mode of putting plummet is carried out centering.This kind method takes a lot of work, time-consuming, and cause accuracy of alignment not high because the thickness of steel wire and line pendant are subjected to the impact of wind-force etc., be difficult to guarantee converter evaporated flue end center, oxygen rifle, oxygen rifle insert port center and 4, converter mouth center being aligned.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides and a kind ofly can guarantee converter evaporated flue end center, oxygen rifle, the oxygen rifle of 4 being aligneds in oxygen rifle insert port center and converter mouth center and the installation centering method of evaporated flue and converter mouth.
The technical solution used in the present invention is:
The installation centering method of a kind of oxygen rifle and evaporated flue and converter mouth, comprise the steps:
A, at converter mouth center, settle laser beam emitting device;
B, adjustment beam direction, make laser beam perpendicular to horizontal plane;
C, flue end target is set; Use translucent film to cover flue end openings place and form flue end target, on flue end target, mark out the position at flue end center;
D, adjustment flue terminal position, make laser beam pass through flue end Target Center;
E, oxygen rifle insert port target is set; Use translucent film to cover oxygen rifle insert port place and form oxygen rifle insert port target, on oxygen rifle insert port target, mark out the position at oxygen rifle insert port center;
F, adjustment oxygen rifle insert port position, make laser beam pass through oxygen rifle insert port Target Center;
G, oxygen rifle centering; Adjust the position of oxygen rifle, make the front end center of laser beam over against the oxygen rifle, the rifle body axis of oxygen rifle is coaxial with laser beam.
The beneficial effect of the relative prior art of the present invention:

Embodiment
The present invention will be described in detail referring to drawings and Examples:
Accompanying drawing 1 is as can be known, and the installation centering method of a kind of oxygen rifle and evaporated flue and converter mouth, comprise the steps:
A, determine converter mouth 7 centers with the planche cross frame of scale, settle laser beam emitting devices 5 at converter mouth 7 centers;
B, adjustment laser beam 4 directions, make laser beam 4 perpendicular to horizontal plane, and namely laser beam 4 is perpendicular to the plane at converter mouth 7 places;
C, flue end target 8 is set; Use translucent film to cover flue end 3 opening parts and form flue end targets 8, on flue end target 8, mark out the position at flue end 3 centers with the planche cross frame of scale;
D, adjustment flue end 3 positions, make laser beam 4 pass through flue end target 8 centers, now flue end 3 centers and converter mouth 7 center;
E, oxygen rifle insert port target 9 is set; Use translucent film to cover oxygen rifle insert port 2 places and form oxygen rifle insert port targets 9, on oxygen rifle insert port target 9, mark out the position at oxygen rifle insert port 2 centers with the planche cross frame of scale;
F, adjustment oxygen rifle insert port 2 positions, make laser beam 4 pass through oxygen rifle insert port target 9 centers; Now oxygen rifle insert port 2 centers and converter mouth 7 center;
G, oxygen rifle 1 centering; Adjust the position of oxygen rifle 1, make the front end center of laser beam 4 over against the oxygen rifle, the rifle body axis of oxygen rifle 1 is coaxial with laser beam 4.
The installation centering method of oxygen rifle of the present invention and evaporated flue and converter mouth, the converter mouth center that selection is in stationary state is reference point, one laser beam emitting device is set in the above, laser beam is perpendicular to upwards emission of horizontal plane, on the straight line at laser beam place, evaporated flue end oxygen rifle insert port and oxygen rifle
are installed respectively.Utilization of the present invention be light along the rectilinear propagation principle, and the propagation that laser has poly-and loose characteristic, light is not subjected to the characteristics of the impact of external force can guarantee the stable of alignment.
The installation centering method of oxygen rifle of the present invention and evaporated flue and converter mouth, reduced installer's labour intensity, improves the precision of installing, and accelerates the speed of installing, and saves the installation work cost, improved installation effectiveness.
