Description
Technical field
The invention belongs to technical field of metallurgical equipment, the blowing slag-removing mechanism of more particularly to a kind of desulfurizing iron.
Background technology
In steelmaking process, the molten iron after desulfurization process must remove the desulfurization slag on molten iron surface, in order to avoid steel-making
Shi Zaocheng returns sulphur.Steel mill is equipped with Cinder Machine and blowing slag-removing device, and blowing slag-removing device is that the auxiliary of desulfurizing iron is taken off
Slag equipment, it is acted on is that auxiliary Cinder Machine is skimmed, and effectively solves the scattered slag in hot-metal bottle, shoddye and pulls out problem, improves
Depeeling rate, and then iron loss is reduced, it is that steel mill produces huge economic benefit.At present, most of blowing slag-removing devices are insertion iron
Water level certain depth, causes molten iron to stir, makes molten iron surface slag by one end using the opposition of steel ladle by blowing
The other end is gathered, finally recycles Cinder Machine to pull down slag.In order to adapt to high temperature liquid iron, plug-in type blowing slag-removing device blows
Air gun head need to use the resistance to material of casting, but even using resistance to material of casting, also easily by broken under conditions of high temperature is born for a long time
It is bad, therefore the operation stove number of pipette tips is limited, and plug-in type injection is also easy to occur stifled rifle, so as to influence to catch up with slag effect.Together
When, stir perturbed force to barral of a gun to balance molten iron during blowing slag-removing, it is necessary to ensure the strength and stiffness of barral of a gun (as pinched
Formula barral of a gun etc.), the volume increase of equipment is so allowed for, mechanism is complicated.
The Chinese utility model patent of Application No. 201120551436.1 provides a kind of contactless blowing slag-removing dress
Put, but it is only capable of realizing single injector blowing slag-removing, and efficiency is low, and the operating time is long；Meanwhile, because desulphurization and slag skimming need to consider that hot-metal bottle can
It can be skimmed in different molten iron levels height and in the case of tumbling to different angles, so blowing slag-removing device not only needs
Consider to catch up with the lifting of slag rifle, and be also contemplated that and catch up with slag rifle to be swung in the range of certain angle, only in this way, blowing slag-removing
Device could meet smelting converter environment requirement.
The content of the invention
