Abstract
The utility model belongs to STEELMAKING PRODUCTION equipment technical field, discloses a kind of practical skimming device of coverter pig, is provided with small kickstand, and the upper end of the small kickstand is welded with supporting rack, movable arms are movably installed on the inside of support frame as described above；The front end of the movable arms is welded with skimming ball towing loop, and the rear end of the movable arms is welded with handle.The practical skimming device of the coverter pig directly controls movable arms by handle in smelting high carbon steel, realizes that skimming ball towing loop carries out pushing off the slag, the factors such as basicity of slag height is avoided to influence pushing off the slag effect.
Description
Technical field
The utility model belongs to STEELMAKING PRODUCTION equipment technical field more particularly to a kind of practical skimming device of coverter pig.
Background technology
Currently, in pneumatic steelmaking production process, slag-stopping tapping is the technique needs for improving steel quality.For it is medium-sized with
On converter, generally pass through slag retaining cone slag-stopping tapping.Affected by various factors, pushing off the slag efficiency can only achieve 80% or so, steel
Water quality declines；In order to improve steel quality, needs to add deoxidier, increase consumption, cost increase.
In conclusion problem of the existing technology is：The slag-stopping tapping device pushing off the slag efficiency of existing pneumatic steelmaking
80% or so is can only achieve, steel quality declines.In order to improve steel quality, needs to add deoxidier, increase consumption, in cost
It rises.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of practical skimming device of coverter pig.
The utility model is realized in this way the practical skimming device of the coverter pig is provided with small kickstand, the trolley
The upper end of holder is welded with supporting rack, and movable arms are movably installed on the inside of support frame as described above；
The front end of the movable arms is welded with skimming ball towing loop, and the rear end of the movable arms is welded with handle.
Further, the lower end of the small kickstand is movably installed with wheel.
Further, the outer cover of the handle is equipped with thermal insulation layer.
The utility model has the advantage that and actively has the technical effect that：The practical skimming device of the coverter pig is in smelting high carbon
Directly movable arms are controlled by handle when steel, realize skimming ball towing loop carry out pushing off the slag, avoid basicity of slag height etc. because
Element influences pushing off the slag effect.
Description of the drawings
Fig. 1 is the practical skimming device schematic diagram of coverter pig that the utility model embodiment provides.
In figure：1, skimming ball towing loop；2, movable arms；3, small kickstand；4, supporting rack；5, wheel；6, handle.
Specific implementation mode
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing.
The practical skimming device of the coverter pig is provided with small kickstand 3, and the upper end of the small kickstand 3 is welded with supporting rack
4,4 inside of support frame as described above is movably installed with movable arms 2；
The front end of the movable arms 2 is welded with skimming ball towing loop 1, and the rear end of the movable arms 2 is welded with handle 6.
The lower end of the small kickstand 3 is movably installed with wheel 5.
The outer cover of the handle 6 is equipped with thermal insulation layer.
It when using slag retaining cone operation failure, can at once be launched using skimming ball towing loop 1, carry out pushing off the slag operation, it will not
Influence steel quality；When finding that clinker is sticky in tapping process, 1 pushing off the slag of skimming ball towing loop can be used instead at once, ensure pushing off the slag
Effect；When smelting middle, high-carbon, it can directly use pushing off the slag trolley to launch skimming ball and implement pushing off the slag operation, improve pushing off the slag rate；When
After pushing off the slag operation failure, second of dispensing can be carried out immediately, clinker is avoided to flow in ladle.
Pushing off the slag rate can reach 95% or more, and be simple to manufacture, at low cost, and maintenance cost is few, safe and reliable in production.
In use, during bessemerizing, skimming ball can be contained onto skimming ball towing loop 1, be put into converter platform
It is spare.When tapping proceeds to about 3/4ths, operation handle 6 shifts trolley by converter onto, by movable arms 2 by pushing off the slag
Ball is sent to tapping hole position in stove and implements pushing off the slag operation.
Or when former slag retaining cone pushing off the slag fails, pushing off the slag trolley is pushed to launch skimming ball, makes up origin operation deficiency.
Or when in tapping process finding that clinker is sticky, skimming ball pushing off the slag can be used instead immediately, prevent former pushing off the slag from operating
Failure.
Or after a pushing off the slag operation failure, skimming ball can be put into skimming ball towing loop 1 immediately, carried out second
It launches, completes pushing off the slag operation.
The operation of the utility model trolley is flexible, easy to use, and mechanical breakdown will not occur.
Dispensing skimming ball support arm is that head is not interfering with pushing off the slag trolley just when converter tilt angles degree changes
Often work.
After a pushing off the slag operation failure, second of dispensing can be carried out immediately, and avoidable clinker flows in ladle.
The pushing off the slag trolley of offer can immediately be remedied in former pushing off the slag operation failure, it is ensured that pushing off the slag operates not by shadow
It rings.The small automobile-used skimming ball pushing off the slag can also be directly applied when smelting middle, high-carbon, and the factors such as basicity of slag height is avoided to influence
Pushing off the slag effect.This pushing off the slag trolley pushing off the slag rate can reach 95% or more, and be simple to manufacture, and at low cost, maintenance cost is few, production
It is upper safe and reliable.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
