Background technology
One essential important step of modern steel desulfurization is molten iron pretreatment, and the molten iron of desulfurization adds converter and entered
Row steel-making.Converter enters stove molten iron band slag and brings numerous difficulties to converter smelting, not only influences the accurate control of Impurities of Molten Steel content,
Also increase flux consumption simultaneously, extend the duration of heat, cause steel quality to fluctuate, production cost rises, efficiency declines.Mesh
Before, iron and steel enterprise is generally controlled into the stove molten iron band quantity of slag, especially for the iron by pretreatment using hot-metal bottle slag skimming process
Water, return in molten steel, as far as possible should remove pretreatment slag dry in steelmaking process to reduce the impurity element of pretreatment removing
Only.As can be seen here, it is one of key factor for influenceing steel quality, STEELMAKING PRODUCTION efficiency and cost that hot-metal bottle, which is skimmed, has been developed
As the indispensable process of modern steel enterprise.
In steel industry, liquid slag is skimmed, is just low typically by the position of hot-metal bottle tipping to slag removal device
Realized in the position at iron/slag interface.But common issue existing for Slagging-off device is slag removal device can not reach hot-metal bottle after
At the slag blanket of wall, so the bits only started around skimming gate could be pulled down quickly, it is decreased obviously the rate of skimming.For
Dregs are made ceaselessly to be flowed out with slag removal device, it is desirable to which in hot-metal bottle the bits of distant place have to move to the domain of walk of slag removal device
It is interior.

Enter end to be connected with dynamical system, output end and the moving cart of the linear motion transmission are connected, described to blow
The end of air gun and moving cart is flexibly connected, and the end set of the air blow gun has spout, the gas blow pipe and scavenger system
Connection, the gas blow pipe and spout connection, the guiding mechanism include horizontal segment and tilting section, and the horizontal segment is with tilting section
It is rotatably connected, the moving cart is arranged on guiding mechanism, and the air blow gun is arranged on guiding mechanism.
It is further that the linear motion transmission is expansion link.
It is further that the guiding mechanism is load-bearing guide rail, the moving cart bottom is provided with roller, the air blowing
Rifle bottom is provided with roller.
Being further that the horizontal segment of the guiding mechanism is provided with is fixedly connected with mechanism, the inclination of the guiding mechanism
Section, which is provided with, is fixedly connected with mechanism.
It is further that the tilting section of the guiding mechanism and the angular range of horizontal direction are 30 ° to 60 °.
The beneficial effects of the invention are as follows：Using the desulfurizing iron blowing slag-removing device of the application, in hot metal pre process procedures
On the basis of original layout, emphasis considers the space around existing mill construction and preprocessing station, realizes mechanical structure light weight
Change, mechanism yardstick and its compact-sized, there is big working space/volume ratio, stabilization of equipment performance height, air blowing auxiliary is skimmed effect
It is good.
