Abstract
The utility model relates to a composite slag stopper, which comprises a tapping hole plug and a sealing ring, wherein, the sealing ring is sleeved at the lower part of the cone frustum-shaped tapping hole plug; a circular cavity pore, which is provided with an opening at the lower end and formed by bending a steel plate, is formed in the middle of the tapping hole plug; an irregular piliferous wing is processed on the outer wall of the steel plate; a steel plate with a hole in the center is arranged at the bottom end of the tapping hole plug, and is connected with a pored steel plate; before oxygen is blown in a converter, the slag stopper is plugged in a tapping hole by the steel plate from the external of the converter, the sealing ring is plugged on the inner wall of the tapping hole, so that iron slag is prevented from spilling from the tapping hole, which eliminates the potential safety hazards; and smoke dust is enabled to be discharged from the upper part of the converter and is processed by a dedusting system, so that the smoke dust pollution and the personal injury are reduced, and the water quality is not influenced. The slag stopper has the advantages of simple structure, low cost, portability, flexibility, convenient operation, safety and reliability.
Description
Technical field
The utility model belongs to the attached utensil of steel-making field, the compound slag stopper that particularly a kind of converter taphole is used.
Background technology
In the blowing oxygen converter steelmaking process, oxygen blast is one requisite treatment process.Yet, when winding-up oxygen in converter, flue dust in the converter will be scurried out from tap hole, because flue gas and amount of dust are big, tap hole is far away again apart from dust-removal system in addition, and dust-removal system can't siphon away the flue dust of emerging, thereby causes smoke contamination, degradation manipulation environment not only, and influence the healthy of staff.Even more serious is, in whole winding-up oxygen process, the molten iron in the stove is in extremely boiling state all the time, and the molten iron of splash especially slag iron can constantly spill from tap hole, very easily causes burning accident, operator's personnel safety is constituted greatly threaten.In order to eliminate the problem of smoke contamination and scum splash in the oxygen blast process, each steelworks was all once taked a lot of different solutions, but because special position and the condition of tap hole, around the used in addition converter taphole " extension wax ", rough and uneven in surface can't shutoff, cause problem unresolved always.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, aims to provide a kind of simplely, safe and reliable, can prevent from effectively that the tap hole flue dust from emitting with scum outward to spill, and reduces the slag stopper of environmental pollution and burning accident.
For this reason, the solution taked of the utility model is:
A kind of compound slag stopper is made up of tap hole plug and sealing-ring, is with a sealing-ring in the bottom of truncated cone tap hole plug, is provided with the circular vestibule of a lower ending opening in the middle of the tap hole plug; The circular vestibule of tap hole plug is to be bent by steel plate to form, and is processed with irregular list edge on the steel plate outer wall; Also be provided with center steel plate with holes in the bottom of tap hole plug, this steel plate is connected with the vestibule steel plate.
Tap hole portion's size and gradient beyond the Great Wall cooperates according to the concrete size of converter taphole and determines.Described sealing-ring is the annulus frustum that adopts ceramic fiber to make for adopting described sealing-ring; The tap hole plug adopts refractory materials vibratory compaction.
After iron has been converted in converter and before the oxygen blast, utilize a steel pipe that is inserted in suitable length in the tap hole consent chamber, this slag stopper is filled in the interior front portion of converter taphole from the converter outside, sealing-ring then shutoff on the inwall of tap hole, because sealing-ring system adopts the ceramic fiber with excellent toughness and refractoriness to make, it can be fitted with the tap hole inwall well, stop slag iron and objectionable impurities to spill the possibility of hurting sb.'s feelings from tap hole fully because of Converter Oxigen Blowing, liquid slag and the objectionable impurities that enters in the tap hole early stage that more can prevent to tap enters in the ladle, influences the purity and the quality of molten steel.In addition,, flue dust can only be emerged from converter top, and disposed, reduced the pollution and the damage to person of flue dust, thereby made the utility model have safety and environmental protection double effects concurrently by dust-removal system because tap hole is dead by the slag stopper complete closed.It is simple in structure, and is cheap, and light and flexible is convenient to operation and safe and reliable.
Description of drawings
Fig. 1 is compound slag stopper diagrammatic cross-section.
Fig. 2 is compound slag stopper vertical view.
Among the figure: tap hole plug 1, vestibule 2, vestibule steel plate 3, list edge 4, sealing-ring 5, steel plate 6.
Embodiment
By accompanying drawing as seen, the utility model is made up of tap hole plug 1 and sealing-ring 5.Tap hole plug 1 is the circular cone stage body that a side has constant slope, and 5 of sealing-rings are an annulus frustum.Tap hole plug 1 adopts the vibratory compaction of refractory materials injection molding, and sealing-ring 5 is made for refractory ceramic fibre.With the lower end that sealing-ring 5 is inserted in tap hole plug 1, promptly form the compound slag stopper of rank trapezoidal shape of the utility model.Embodiment in the middle of tap hole plug 1, be provided with a vestibule steel plate 3 that has a list edge 4 by the surface along the axis of tap hole plug 1 and bend the conical vestibule 2 that forms, also be provided with center steel plate with holes 6 in the bottom of tap hole plug 1, and steel plate 6 is connected with vestibule steel plate 3.The effect of vestibule 2 mainly is when alleviating slag stopper weight, as the usefulness of intubate, so that the laying of slag stopper.Vestibule steel plate 3 is set prevents that the steel pipe that inserts from breaking tap hole plug 1, and be connected with steel plate 6.List edge 4 can increase by 3 surface resistances of vestibule steel plate, makes refractory materials and vestibule steel plate 3 bond more firmly.
