Description
Technical field
The present invention relates to metallurgical technology fields, mend aluminium device more specifically to a kind of ladle and its mend aluminium method.
Background technology
It is a kind of new technique for requiring extra high steel grade to use to carry out ladle metallurgy on continuous casting revolving platform in ladle, especially
It is the steel grade sternly required for some high standards, and the composition of dissolved aluminum is a most important chemical index, once in this ring
Section does not adjust ingredient, or melting down or scrapping after composition comes out, melts down to add and sentences useless rate up to 5.6%.And
The exploitation that ladle mends aluminum technology can be good at making up the risk brought since double refining composition adjustment is not in place, while
Properties of product can accurately be met.
It is to encounter the low heat of refining end sample aluminium that currently used ladle, which mends aluminium method, and operative employee just holds aluminium bar
(or being ladle) is directly thrown into the ladle for filling with molten steel, due to all throwing away in the surface of ladle molten steel, one layer of slag on surface
Son can all absorb these aluminium, and Al yield at this time is at a fairly low, and the qualification rate for mending aluminium is only 20% or so, therefore the benefit aluminium
Although method makes to melt down and sentence useless rate in a slight decrease, but also reaches 4.5% or more.
Therefore how to mend aluminium to ladle on revolving platform is just particularly important, and relates in one aspect to safety problem, many institutes
It is known, it is the high-temp liquid of a fully loaded molten steel on the revolving platform of continuous casting, if not accomplishing to protect well, it is possible to occur
The accidents such as burn, scald；Another aspect ladle can all generate knot lid phenomenon in the case of refining out one, it is desirable to very well
Cover aluminium bar, just must first carry out break lid operation, so need a kind of break operation that can either be conveniently operated personnel,
The device of molten steel composition effectively adjusted can be ensured again.
Invention content
In view of the above defects of the prior art, the object of the present invention is to provide a kind of ladles to mend aluminium device and its benefit

The lower section for making bar body, by supporting block so that operation bar body is set on the railing of revolving platform, the threaded upper ends for covering fourth finger connect
In on the end face of operation bar body front end, lower end is connected with aluminium bar.
It is additionally provided with spiral button on the set fourth finger, to tightening sleeve fourth finger, prevents aluminium bar from falling off.
The direction controller is made of stainless steel.
The supporting block setting is triangular in shape, and the bottom edge of triangle is set on the railing of revolving platform, and apex angle is connected in behaviour
Make the lower section of bar body.
The vertex angle is connected in below operation bar body on the position of distance operation bar body rear end 500mm.
The aluminium bar upper end is connected with set fourth finger, and the lower end setting of aluminium bar is in cone.
On the other hand, a kind of method that ladle mends aluminium, includes the following steps：
S1. one layer of heating block is spread in the molten steel surface of ladle, in order to continuous casting break；
S2. this benefit aluminium device is mounted on the railing of revolving platform, this benefit aluminium device is held by direction controller
All around move；
S3. break is carried out to molten steel surface in ladle using the lower end of aluminium bar, then aluminium bar is inserted into molten steel again；
S4. aluminium bar is dissolved in ladle in molten steel, and the self-loopa by molten steel in ladle so that the ingredient in molten steel
Uniformly, to achieve the purpose that mend aluminium.
In the above technical solution, a kind of ladle provided by the present invention mends aluminium device and its mends aluminium method, not only can
It is enough that break is carried out to molten steel surface, so that aluminium bar is smoothly dissolved in molten steel, additionally it is possible to ensure that entire ladle benefit aluminium operation can
It safely and effectively carries out, prevents the generation of major accident, and the product quality of molten steel can be improved in a short time.
