Abstract
The present invention belongs to the field of steel smelting, which relates to a steel-smelting slag-discharging device, particularly to a device for discharging slag in the process of smelting steel. The steel-smelting slag-discharging device is composed of a slag-discharging cap 1, a slag-blocking barrel 2, a bobweight 3, the refractory material coating 4 of the slag-blocking barrel, the refractory material coating 5 of the slag-discharging cap, the position limiting ring 6 of the slag-blocking barrel, the hanging ring 7 of the slag-discharging cap, the hanging ring 8 of the slag-blocking barrel, and an indicating lamp 9 for the appearance of a positioning steel column with molten steel. When the present invention is used, the slag-discharging cap 1 with a horn-shaped truncated cone is put in a steel containing barrel, and gradually sinks into slag under the function of the bobweight 3, the slag gradually rises along the lower surface of the horn-shaped truncated cone of the slag-discharging cap and flows into the upper surface of the horn-shaped truncated cone of the slag-discharging cap through the upper part of the slag-discharging cap, and then the circumference of the slag is blocked by the slag-blocking barrel. When the slag is discharged and the molten steel is adjacent to the upper surface of the horn-shaped truncated cone of the slag-discharging cap, the molten steel appears so that the indicating lamp 4 is turned on, and the hanging ring 7 of the slag-discharging cap is hung up so that the steel-smelting slag-discharging device is disengaged from the steel containing barrel. The present invention has the characteristics of low labor intensity, rapid slag discharging, little temperature reduction of the molten steel and simple equipment.
Description
Technical field
The invention belongs to field of steel-making, particularly a kind of equipment of in steelmaking process, getting rid of slag.
Background technology
Get rid of slag and help gas and non-metallic inclusions such as hydrogen, nitrogen in decarburization, deoxidation, desulfurization, the removal steel.
Also there are some problems in used deslagging method at present, and anxious to be solved: 1 with regard to manually skimming, and labour intensity is too big, and the time is long, and molten steel temperature drop is greatly its deadly defect.2 with regard to the machinery of present employing is skimmed, and the fast inadequately and big problem of molten steel temperature drop of speed is also arranged.3 with regard to the vacuum deslagging, the equipment more complicated, and be Japanese equipment, need with remitting purchase outward.4 with regard to slag-blocking ball, though the pushing off the slag effect is pretty good, only is applicable to the occasion of converter tapping.
Summary of the invention
The present invention seeks in order to solve the present machinery speed of skimming slow and molten steel temperature drop big, vacuum residue extraction mechanism complexity, colored foreign exchange, problem that cost is high.
A kind of steel-smelting slag-discharging device, slag off apparatus pilot lamp 9 occurs by refractory coating 5, sediment block canister position limit ring 6, sediment ejected cap hoisting ring 7, sediment block canister suspension ring 8, location steel column and the molten steel of the refractory coating 4 of dreg discharging cap 1, sediment block canister 2, counterweight 3, sediment block canister, dreg discharging cap and constitute.Sediment block canister 2 bottom lower surfaces are planes, lie on the upper surface of dreg discharging cap 1 bottom.Sediment block canister 2 can slide up and down along four steel columns under the sediment ejected cap hoisting ring 7 in sediment block canister position limit ring 6, during use the dreg discharging cap 1 of trumpet truncation cone is put into steel teeming ladle, under the effect of counterweight 3, dreg discharging cap 1 sinks in the slag, slag rises along the lower surface of dreg discharging cap trumpet truncation cone, flow to the upper surface of dreg discharging cap trumpet truncation cone by dreg discharging cap top, blocked by sediment block canister all around.When slag emptying, molten steel during to the upper surface of dreg discharging cap trumpet truncation cone, molten steel pilot lamp 9 occurs and lights, and the sediment ejected cap hoisting ring 7 of slinging allows slag off apparatus break away from steel teeming ladle.In order to remove the slag in the slag off apparatus, transport slag off apparatus with the crane main hook behind the slag field by sediment ejected cap hoisting ring 7, make main hook motionless, utilize the little hook of crane to promote sediment block canister 2 by the suspension ring 8 of deslagging tube, allow slag from slag off apparatus outside impouring slag field.
For preventing scattering and disappearing of heat, sediment block canister 2 will be made tapered, and external diameter is than the little 200-300mm of steel teeming ladle interior diameter, and the sediment block canister tapering is identical with the steel teeming ladle tapering.The dreg discharging cap upper and lower surface is evenly equipped with the high barb of 30-40mm, and the internal surface of sediment block canister is provided with the high barb of 30-40mm, so that the coating refractory materials.
The characteristics of this equipment are:
1 according to Archimedes' principle, utilizes the dreg discharging cap with tubaeform frusto-conical surface that slag is entered in its outer annular slag off apparatus.
2 in order to remove the slag in the slag off apparatus, can utilize crane to promote sediment block canister, allows slag from slag off apparatus outside impouring slag field.
3 because the proportions of molten steel and slag differ very big (7 with 1-4.5 ratio), in order to get rid of slag, how slag off apparatus are fallen into molten steel, are exactly the problem of key, have installed the counterweight of certainweight on shelves slag tube top for this reason.
4 in order to prevent that molten steel from flowing into slag off apparatus, removes two steel columns in order to the installing suspension ring, and outside the lifting slag off apparatus, two other open tubular column then is used for by insulation tube installing electric wire and pilot lamp to show the moment of molten steel.

Embodiment
Slag off apparatus pilot lamp 9 occurs by refractory coating 5, sediment block canister position limit ring 6, sediment ejected cap hoisting ring 7, sediment block canister suspension ring 8, location steel column and the molten steel of the refractory coating 4 of dreg discharging cap 1, sediment block canister 2, counterweight 3, sediment block canister, dreg discharging cap and constitutes.Sediment block canister 2 bottom lower surfaces are planes, lie on the upper surface of dreg discharging cap 1 bottom.Sediment block canister 2 can slide up and down by four steel columns along sediment ejected cap hoisting ring 7 in sediment block canister position limit ring 6, during use the dreg discharging cap 1 of trumpet truncation cone is put into steel teeming ladle, under the effect of counterweight 3, dreg discharging cap 1 sinks in the slag, slag rises along the lower surface of dreg discharging cap trumpet truncation cone, flow to the upper surface of dreg discharging cap trumpet truncation cone by dreg discharging cap top, blocked by sediment block canister all around.When slag emptying, molten steel during near the upper surface of dreg discharging cap trumpet truncation cone, molten steel pilot lamp 9 occurs and lights, and the sediment ejected cap hoisting ring 7 of slinging allows slag off apparatus break away from steel teeming ladle.In order to remove the slag in the slag off apparatus, transport slag off apparatus with the crane main hook behind the slag field by sediment ejected cap hoisting ring 7, make main hook motionless, utilize the little hook of crane to promote sediment block canister 2 by the suspension ring 8 of deslagging tube, allow slag from slag off apparatus outside impouring slag field.
