Abstract
The invention relates to a method for fixing a stopper rod, which consists of an upper arm, a lower arm and a clamping piece, wherein both ends of the upper arm and the lower arm are respectively provided with a part of inner spherical surface or inclined surface which is matched with an outer spherical surface joint on the stopper rod. The ball joint of the stopper rod is placed in the inner spherical surface or inclined plane between the upper arm and the lower arm, the stopper head is adjusted to be matched with the water gap, and the upper arm and the lower arm are clamped tightly, so that the stopper head and the water gap can not shift any more. The method can shorten the adjusting time, ensure the adjusting precision, and reduce the material of the plug and the nozzle and correspondingly reduce the steelmaking cost due to the improvement of the precision.
Description
The present invention relates to a kind of steel-making throttling arrangement, is the method that is used for fixing stopper on ladle or the pans.
When stopper is installed, in order to reach the effect of stopper energy better controlled steel stream, just must well coincide the nock position of the chock plug position of stopper and sprue gate, but in practical operation, adopt the method for feel and range estimation to conclude whether chock plug is identical with the nock position of sprue gate often, this method requires to improve to workman's qualification and operant level, though through repeatedly adjusting, but whether chock plug is genuine identical with the mouth of a river, can only judge with feeling.So at present the stopper that adopts out-of-control phenomenon occurs in the casting process of being everlasting, this is because chock plug is not identical with the mouth of a river fully, and steel flow is washed away inhomogeneous causing to chock plug and the mouth of a river.What the stopper out-of-control phenomenon was given pouring in steel smelting technology normally brings very big difficulty, causes a large amount of waves of molten steel useless when serious.
In order to address this problem, the method that adopts is to improve the material at the chock plug and the mouth of a river at present, and for example application number is that 95216572.4 utility model patent is that compound zirconium matter composite bed improves the erosion resisting at the mouth of a river at the mouth of a river.Application number is 92106398.9 patent of invention, and application number is 92211433.1 utility model patent, and application number is that 93107549.1 patent of invention is all made the chock plug position with high-grade anti-material.Though take these measures can reduce the stopper out-of-control phenomenon, because of its cost of manufacture higher, the corresponding steel-making cost that increased.
The purpose of this invention is to provide a kind of stopper fixing means, this method can make the chock plug position of stopper and the nock position of sprue gate coincide easily, very accurately.
The object of the present invention is achieved like this: the metal bar on stopper top is made the spherical outside surface body, and transverse arm makes by upper and lower arm clamp arm dimerous, and the front end of upper and lower arm has Internal Spherical Surface, and this Internal Spherical Surface is to match with spherical outside surface body joint on the stopper.Spheroid on the stopper is put into the Internal Spherical Surface of upper and lower arm, stopper device is operated closed dead position again, at this moment the chock plug and the mouth of a river fit like a glove, and then upper and lower arm are clamped, and so just guarantee that the chock plug and the mouth of a river coincide.
Because this is invented described clamping means and has adopted the sphere location, so can easily the chock plug and the mouth of a river be coincide, in whole casting process, the erosion at the stopper and the mouth of a river all is more uniform, even the material at the chock plug position and the mouth of a river is a little inferior slightly, also can guarantee stopper device better controlled molten steel flow speed.This invents described method can alleviate the labour intensity that the workman adjusts stopper, shortens the adjustment time, can reduce the production cost of stopper again.
Below in conjunction with drawings and Examples the present invention is done further explanation.
Fig. 1 is the profile of the method for the fixing plunger be made up of upper arm, underarm, clamping linkage and spring preloading device.
Fig. 2 is the profile of the method for the fixing plunger formed of upper arm, underarm and clamping screw.
The top of stopper (1) is a joint (2) that has the spherical outside surface body, globe joint is contained in the Internal Spherical Surface between upper arm (4) and the underarm (3), upper arm (4) and underarm (3) are assembled together, be installed on the lowering or hoisting gear (7), lowering or hoisting gear (7) is installed on the tundish (8), on sprue gate (9) is installed at the bottom of the bag of tundish (8).
In the embodiment shown in fig. 1, the opening of upper arm (4) and underarm (3) closed tightly and finished by clamping linkage (5), in order to guarantee under high-temperature baking, upper arm (4) and underarm (3) distortion back clamping force still keep dress state just, at the afterbody of upper arm (4) and underarm (3) adjustable spring preloading device (6) have been installed.
In the embodiment shown in Figure 2, the opening and close tightly by screw rod (10) and round nut (11) and finish of upper arm (4) and underarm (3), upper arm (4) and underarm (3) lean on Xiao Zi (12) to link together.
Claims (4)
1, a kind of method of fixing plunger is characterized in that, is made up of upper arm and underarm and clamping element.
2, according to claim 1, it is characterized in that each some Internal Spherical Surface of the front end of upper arm and underarm.
3, according to claim 2, it is characterized in that the Internal Spherical Surface of upper arm and underarm front end also can be the inclined-plane.
4, according to claim 1,2 or 3, it is characterized in that the Internal Spherical Surface of upper arm and underarm front end or inclined-plane are to match with spherical outside surface body joint on the stopper.
