Abstract
The utility model relates to a molten iron pretreatment skimming plate, including skimming the board, skimming the board by skimming board one and skimming two and constitute, the top of skimming board one is fixed at the tip of skimming the pole through the bolt, is fixed with skimming board two through the bolt on the skimming pole of 200 + 700mm department apart from skimming board one side, and the top of skimming board one and skimming board two is the arc structure, and its radian is 120 + 160 °; the height of the second slag skimming plate is smaller than that of the first slag skimming plate, and the difference value is 100-300 mm; the bottom of the second slag skimming plate is of a sawtooth structure. Compared with the prior art, the beneficial effects of the utility model are that: the slag removing plate for the molten iron pretreatment has the characteristics of simple structure, low cost, convenience in use and strong practicability, effectively reduces slag removing dead zones and slag removing iron loss, improves the slag removing effect, shortens the slag removing time and improves the product quality.
Description
Technical field
The utility model relates to the hot metal pretreatment technical field, particularly a kind of molten iron pretreatment slag skimming plate.
Background technology
Hot metal pretreatment refers to that molten iron is before being blended into steel melting furnace, for removing or extract the treating processes that certain element carries out, wherein desulfurization with skim be two separate, and the hot metal pretreatment technology that is closely connected again, sulfur removal technology has determined to handle the level of terminal point molten iron sulfur-bearing, skimming then is the important means that the high sulphur slag after desulfurization is handled is removed from molten iron, it is the principal element that determines stove sulphur total amount, therefore compare, slag skimming process seems even more important to control sulphur process, if desulfurization product can not get effective removal, good again sulfur removal technology can not play one's part to the full; Therefore, adopting the advanced equipment and technology of skimming is very necessary to system's control sulphur with reducing production costs.
At present, what the process of skimming generally adopted is the hydraulic pressure slag removal machine, smooth operation, controllability is good, and iron loss significantly reduces, and it is more thorough to skim, size according to different iron ladles determines the size that the hydraulic pressure slag removal machine is taken off slag plate, and the plate major part of skimming that generally adopts is rectangle or trapezoidal at present, and is veneer, exist mainly but shortcoming have: the one, take off the slag blanket place that slag plate can not reach wall behind the iron ladle, the dead band of having skimmed; The 2nd, the plate operation of singly skimming, the slag that once removes is less, and slag-removing time is long, and the plate of skimming is done short stay 1-3 second when arriving jar mouthful, and then lifts slag is clawed, thereby reduces the band iron water amount of skimming.
Summary of the invention
The purpose of this utility model provides a kind of minimizing skim dead band and the iron loss of skimming, and improves the effect of skimming, and shortens the molten iron pretreatment slag skimming plate of slag-removing time.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of molten iron pretreatment slag skimming plate, comprise and take off slag plate, the described slag plate of taking off is by taking off slag plate one and taking off slag plate two and form, take off the top of slag plate one by being bolted to the end of skimmer, taking off slag plate two by bolting on the skimmer at side 200-700mm place one by one apart from taking off slag plate, take off slag plate one and take off slag plate two tops and be arcuate structure, its radian is 120-160 °.
Described slag plate two height of taking off are less than taking off slag plate one, and its difference is 100-300mm.
Described slag plate two bottoms of taking off are the prionodont structure.
Compared with prior art, the beneficial effects of the utility model are:
A kind of molten iron pretreatment slag skimming plate has simple in structure, with low cost, easy to use, practical characteristics, has effectively reduced skim dead band and the iron loss of skimming, and has improved the effect of skimming, and has shortened slag-removing time, has improved quality product.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of molten iron pretreatment slag skimming plate of the utility model, comprise and take off slag plate, the described slag plate of taking off is by taking off slag plate 1 and taking off slag plate 22 and form, take off the top of slag plate 1 by being bolted to the end of skimmer 3, taking off slag plate 22 apart from taking off on the skimmer 3 at slag plate one 1 one side 200-700mm places by bolting, taking off slag plate 1 and take off slag plate 22 tops and be arcuate structure, its radian is 120-160 °; Described slag plate 22 height of taking off are less than taking off slag plate 1, and its difference is 100-300mm; Described slag plate 22 bottoms of taking off are the prionodont structure.
When using the utility model, in the process of skimming, the utility model arrives iron ladle jar mouth, and a little lifts and does not do stop, and taking off slag plate 22 bottoms because of it is prionodont, can not cause molten iron to overflow with the process of skimming, and only needs a little to lift, and slag can be clawed iron ladle jar mouth.
Skimming with 120 tons of iron ladles is example, adopts the utility model and does not adopt effect comparison of the present utility model:
| Slag-removing time min | Sulfur content % is returned in converter | The iron loss of skimming molten iron kg/t | |
| The former slag plate of taking off | 13.4 | 0.0041 | 15.8 |
| Newly take off slag plate | 9.3 | 0.0023 | 11.3 |
Above described only be ultimate principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
