Abstract
The utility model discloses a kind of ladle pocket block structure, this structure comprises pocket block body, pocket block body centrally axis offers through upper bellmouth orifice, the first isometrical straight hole, lower bellmouth orifice and the second isometrical straight hole successively, the big opening end of upper bellmouth orifice flushes with the end face of pocket block body, the osculum end of lower bellmouth orifice connects the first isometrical straight hole and osculum end diameter is greater than the diameter of the first isometrical straight hole, and the big opening end of lower bellmouth orifice connects the second isometrical straight hole and big opening end diameter is consistent with the diameter of the second isometrical straight hole.This structure overcomes the defect of traditional pocket block, avoids the direct erosion of molten steel to pocket block, improves scour resistance, thus increases service life, extends ladle maintenance cycle, ensure that normal, the safe handling of ladle.
Description
Technical field
The utility model relates to a kind of ladle pocket block structure.
Background technology
Ladle is the important container piece of metallurgy industry smelting iron and steel, plays the important function of storage, transhipment molten steel, double refining.Along with the development of metallurgical technology, the effect of ladle seems more outstanding, and the length in its service life directly affects normal production and the production cost of steel mill.
An important indicator of ladle life is the repair cycle of ladle, and wherein the pocket block life-span is the key factor affecting the ladle repair cycle.
Bottom of steel ladle is equipped with pocket block and filling pipe end, as shown in Figure 1, the structure of tradition pocket block is be provided with through upper bellmouth orifice 2 and lower bellmouth orifice 3 along the central axis of pocket block body 1, the big opening end of upper bellmouth orifice 2 flushes with pocket block body 1 end face, and the big opening end of lower bellmouth orifice 3 flushes with pocket block body 1 bottom surface.Pocket block is directly installed on the bag end, and filling pipe end loads in pocket block, and filling pipe end and upper bellmouth orifice, lower bellmouth orifice are the passages that molten steel is derived.Ladle pocket block in use, to cold and heat succeed each other and molten steel washes away due to long-term, pocket block can be made to contact molten steel position to be corroded serious, after using a period of time, during the cold and hot replacing of filling pipe end, upper bellmouth orifice and the lower bellmouth orifice joint portion of filling pipe end top and pocket block can produce comparatively wide arc gap, make pocket block shorter for service life, about service life of current ladle pocket block being only 40 stoves, have impact on the stability of production process, ladle uses exists certain potential safety hazard, improves maintenance cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of ladle pocket block structure, this structure overcomes the defect of traditional pocket block, avoid the direct erosion of molten steel to pocket block, improve scour resistance, thus increase service life, extend ladle maintenance cycle, ensure that normal, the safe handling of ladle.
For solving the problems of the technologies described above, the utility model ladle pocket block structure comprises pocket block body, described pocket block body centrally axis offers through upper bellmouth orifice successively, first isometrical straight hole, lower bellmouth orifice and the second isometrical straight hole, the big opening end of described upper bellmouth orifice flushes with the end face of described pocket block body, the osculum end of described lower bellmouth orifice connects described first isometrical straight hole and osculum end diameter is greater than the diameter of the first isometrical straight hole, the big opening end of described lower bellmouth orifice connects described second isometrical straight hole and big opening end diameter is consistent with the diameter of the second isometrical straight hole.
Further, the cross sectional shape of described pocket block body is rectangle or circle.
Because the utility model ladle pocket block structure have employed technique scheme, namely this structure comprises pocket block body, pocket block body centrally axis offers through upper bellmouth orifice, the first isometrical straight hole, lower bellmouth orifice and the second isometrical straight hole successively, the big opening end of upper bellmouth orifice flushes with the end face of pocket block body, the osculum end of lower bellmouth orifice connects the first isometrical straight hole and osculum end diameter is greater than the diameter of the first isometrical straight hole, and the big opening end of lower bellmouth orifice connects the second isometrical straight hole and big opening end diameter is consistent with the diameter of the second isometrical straight hole.This structure overcomes the defect of traditional pocket block, avoids the direct erosion of molten steel to pocket block, improves scour resistance, thus increases service life, extends ladle maintenance cycle, ensure that normal, the safe handling of ladle.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of traditional pocket block;
Fig. 2 is the utility model ladle pocket block structural representation.
Detailed description of the invention
Embodiment as shown in Figure 2, the utility model ladle pocket block structure comprises pocket block body 1, described pocket block body 1 centrally axis offers through upper bellmouth orifice 2 successively, first isometrical straight hole 4, lower bellmouth orifice 3 and the second isometrical straight hole 5, the big opening end of described upper bellmouth orifice 2 flushes with the end face of described pocket block body 1, the osculum end of described lower bellmouth orifice 3 connects described first isometrical straight hole 4 and osculum end diameter is greater than the diameter of the first isometrical straight hole 4, the big opening end of described lower bellmouth orifice 3 connects described second isometrical straight hole 5 and big opening end diameter is consistent with the diameter of the second isometrical straight hole 5.
Further, the cross sectional shape of described pocket block body 1 is rectangle or circle.
This structure still offers bellmouth orifice on the top of pocket block body, not affect the connection with ladle upper nozzle, molten steel flows to the first isometrical straight hole after upper bellmouth orifice, and then flow out through lower bellmouth orifice, the second isometrical straight hole, thus avoid molten steel to the erosion of upper bellmouth orifice and the lower direct-connected joint portion of bellmouth orifice, enhance erosion resistibility, and do not affect the sealing between ladle upper nozzle and pocket block body, improve service life.
The pocket block of this structure is by mechanical pressing, make rectangle or circle, to meet the needs of installation, use through reality, service life brought up to more than 60 stoves by the pocket block of this structure, when guaranteeing that ladle is normal, safe handling, improve the stability of production process, reduce maintenance cost, obtain larger economic benefit.
Claims (2)
