Abstract
The utility model relates to a refining furnace water-cooling bell covers on ladle upper portion, include upper portion bell, lower part bell, bell shirt rim and the bell flue that encloses by the water-cooling coil respectively, upper portion bell, lower part bell, bell shirt rim are arranged from top to bottom in proper order, and the diameter increases in proper order, upper portion bell top surface sets up the resistant material opening that is used for inserting heating electrode, the bell flue link up from the side simultaneously upper portion bell, lower part bell, the bell shirt rim directly covers on the ladle. The turning angle of the furnace cover skirt is 110-130 degrees. The utility model discloses refining furnace bell has solved the problem that the flue caused the unable effective absorption of refining furnace smoke and dust because of gluing the sediment and blockking up when original two flues of adoption smoked respectively upper portion bell and lower part bell. But also overcomes the defects of easy slag accumulation and difficult cleaning at the lower part of the furnace cover, and plays an important role in the production environment of production enterprises and the improvement of slag cleaning operation efficiency.
Description
Technical Field
The utility model relates to a refining furnace of molten steel refining usefulness, concretely relates to bell of this refining furnace.
Background
The refining furnace can produce a large amount of smoke and dust in molten steel processing procedure, and the ladle top sets up the water-cooled furnace lid, and the bell top sets up 3 electrode holes, and the water-cooled furnace lid is coiled by the coil pipe that leads to water and forms, and for confined bell, the inlet scoop will be seted up to the water-cooled furnace lid side as the bell flue, discharges the smoke and dust that overflows in the ladle of refining procedure.
The upper layer of flue is responsible for absorbing and removing smoke dust on the upper part, and the lower layer of flue is communicated with the annular flue on the lower part of the furnace cover and is responsible for absorbing and removing smoke dust emitted from the lower part of the furnace cover. Because the flue becomes very small after the flue is layered, the upper flue can be blocked due to dust deposition in a short time, and the lower annular flue is also blocked due to the rapid accumulation of splashed steel slag. And the furnace is not stopped for removing the slag in the flue at ordinary times, and the problem can be solved only by supporting to overhaul even if the flue is blocked, so after the flue is blocked, the smoke generation condition of the refining furnace is very serious, and the operation environment of workers is seriously influenced. And the slag accumulated on the 90-degree skirt annular flue at the lower part of the furnace cover is very difficult to remove. The normal use of refining dust removal during smelting is guaranteed, the problem that furnace cover slag removal is difficult is solved, clean production is achieved, and related technical personnel are troubled all the time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a refining furnace water-cooling bell is provided to above-mentioned prior art, solve two flues in current upper and lower part and be blocked up easily a difficult problem to and reduce the clearance degree of difficulty of bell lower part shirt rim.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a refining furnace water-cooling bell covers on ladle upper portion, includes upper portion bell, lower part bell, bell shirt rim and the bell flue that becomes by the water-cooling coil pipe encloses respectively, upper portion bell, lower part bell, bell shirt rim are arranged from top to bottom in proper order, and the diameter increases in proper order, upper portion bell top surface sets up the resistant material opening that is used for inserting heating electrode, the bell flue link up from the side simultaneously upper portion bell, lower part bell, the bell shirt rim directly covers on the ladle.
Preferably, the turning angle of the furnace cover skirt is larger than 90 degrees, so that the smoke and scale in the turning angle of the furnace cover skirt can be conveniently cleaned.
Preferably, the turning angle of the furnace cover skirt is 110-130 degrees.
Compared with the prior art, the utility model has the advantages of: the utility model discloses refining furnace bell has solved the problem that the flue caused the unable effective absorption of refining furnace smoke and dust because of gluing the sediment and blockking up when original two flues of adoption smoked respectively upper portion bell and lower part bell.
But also overcomes the defects of easy slag accumulation and difficult cleaning at the lower part of the furnace cover, and plays an important role in the production environment of production enterprises and the improvement of slag cleaning operation efficiency.
Drawings
FIG. 1 is a schematic view of the lid of an original finer;
FIG. 2 is a schematic view of the furnace lid of the refining furnace according to the embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in figure 1, in the water-cooled furnace cover of the prior refining furnace, an upper flue 1 is arranged on the side surface of the upper furnace cover, a lower flue 2 is connected to the bottom of the lower flue, and the upper flue 1 and the lower flue 2 smoke at the same time.
As an improvement, the refining furnace water-cooled furnace cover is redesigned in the embodiment and covers the upper part of a steel ladle opening 8, and comprises an upper furnace cover 3, a lower furnace cover 4, a furnace cover skirt 5 and a furnace cover flue 6 which are respectively surrounded by water-cooled coils, wherein the upper furnace cover 3, the lower furnace cover 4 and the furnace cover skirt 5 are sequentially arranged from top to bottom, the diameters of the upper furnace cover 3, the lower furnace cover 4 and the furnace cover skirt 5 are sequentially increased, a refractory material through opening 7 for inserting a heating electrode is formed in the top surface of the upper furnace cover 3, the furnace cover flue 6 simultaneously penetrates through the upper furnace cover 3 and the lower furnace cover 4 from the side surface, the turning angle of the furnace cover skirt 5 is designed to be 115 degrees.
Although the preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
