Abstract

The utility model provides a bottom air blowing type liquid iron pot comprising a liquid iron pot with an open top. The bottom air blowing type liquid iron pot is characterized in that an air-permeable brick is arranged at the bottom of the liquid iron pot; and a metal guide pipe on the air-permeable brick passes through the wall of the liquid iron pot and outwards extends to be connected with an air supply pipe. Liquid iron is agitated and pre-treated through air, so that high-sulfur residues in the liquid iron be completely removed, the temperature of the liquid iron is not greatly reduced; and the smelting effect and the product quality are guaranteed. The bottom air blowing type liquid iron pot is an ideal liquid iron pot for smelting iron.

Description

A kind of bottom blowing formula iron ladle
Technical field
The utility model relates to a kind of iron ladle, and particularly a kind of bottom blowing formula iron ladle belongs to steel smelting equipment manufacturing technology field.
Background technology
Molten iron all need carry out the desulfurization pre-treatment to it before getting into steel melting furnace, so that remove wherein too high objectionable constituent---sulphur.The employing hot metal pretreatment is technological, not only can alleviate the steel-making burden of steel melting furnace, and the while can also be optimized process for making and improve the quality of steel, also is that highly economical ground production high added value super low sulfur steel are created good processing condition.The main at present hot metal pretreatment mode that adopts is a mechanical mixing method, and this method desulfuration efficiency is high, and controls simple.But mechanical mixing method has but brought the deslagging weak effect, and molten iron can't thoroughly separate with slag, causes a large amount of high sulphur slags to get into converter on the one hand, is with iron in the slag on the other hand, causes iron loss to raise, thereby can't satisfy the target of molten iron expection desulfurization.And, have to prolong the deslagging time in order to satisfy desulfurizing iron, and certainly will cause molten iron temperature significantly to reduce like this, not only influence metallurgical effect, also upset the normal production order.Therefore be necessary prior art is improved.
The utility model content
Adopt mechanical agitation desulfuration for solving existing hot metal pretreatment, the high-sulphur molten iron deslagging weak effect that is caused, problem such as the deslagging time is long, and molten iron temperature declines to a great extent, and iron loss is big, the utility model provides a kind of bottom blowing formula iron ladle.
The utility model is accomplished through following technical proposal: a kind of bottom blowing formula iron ladle, comprise that its top is open iron ladle, and it is characterized in that the iron ladle bottom is provided with gas permeable brick; Metal tubing on this gas permeable brick passes the molten iron tank skin and stretches out and link to each other with air-supply duct, so that the rare gas element that air-supply duct is carried is sent in the iron ladle through metal tubing, gas permeable brick, blows with the molten iron in it; And stirring molten iron by force, the promotion sweetening agent contacts with molten iron, improves the dynamic conditions of desulphurization reaction; Improve desulfuration efficiency, simultaneously in the process of skimming, through the effect of bottom blowing air-flow; Make the slag fluctuation on molten iron surface and come together in skimming gate, help slagging-off.
Have the hole on the refractory masses of said iron ladle bottom and the thermal insulation layer, gas permeable brick is located in this hole, and is the fire resistant infilling packing layer between hole and the gas permeable brick, so that the fixed ventilation brick.
Figure DEST_PATH_IMAGE001
said gas permeable brick is to iron ladle axis direction inclination 25-30 degree; And the gas permeable brick top is higher than the refractory masses of iron ladle bottom; So that to the processing of skimming of gas permeable brick top, prevent that simultaneously the molten iron residue from stopping up gas permeable brick.
The gas permeable brick of said band metal tube is located at distance of shaft centers tank wall 1/3rd places, iron ladle bottom, so that make the bottom blowing effect reach best effect.
The utlity model has advantage and effect: adopt such scheme, will come preprocessed molten iron through churned mechanically mode originally, change into and bottom iron ladle, set up gas permeable brick and come molten iron is carried out pre-treatment through gas.Make that so not only the high sulphur slag in the molten iron can all be cleaned out, and can not make molten iron temperature that the excessive range of decrease is arranged, guaranteed metallurgical effect and final product quality.Be that iron ladle is used in ideal ironmaking in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The bottom blowing formula iron ladle that the utility model provides; Comprise that its top is an iron ladle 3 uncovered, that inwall is established refractory masses 1 and thermal insulation layer 2; The refractory masses 9 of iron ladle 3 bottoms and thermal insulation layer 8 perforates 4 are provided with gas permeable brick 5 in this hole 4, are filled with fire resistant infilling 7 between hole 4 and the gas permeable brick 5; Be used for fixing gas permeable brick 5; Metal tubing 6 on the gas permeable brick 5 passes iron ladle 3 walls and stretches out and link to each other with air-supply duct, and
Figure 669201DEST_PATH_IMAGE001
gas permeable brick 5 is to iron ladle axis direction 25 degree that tilt, and gas permeable brick 5 tops are higher than the refractory masses 9 of iron ladle 3 bottoms; So that to the processing of skimming of gas permeable brick top; Prevent that simultaneously the molten iron residue from stopping up gas permeable brick, gas permeable brick 5 is located at distance of shaft centers tank wall 1/3rd places, iron ladle 3 bottom, so that make the bottom blowing effect reach best effect.
