Abstract
The utility model discloses a cooling unit on blast-furnace tuyere, which is characterized by comprising a cooling plate (1) which is fixed on a furnace shell and positioned on the upper part of the tuyere, and a cooling wall (2) which is fixed on the furnace shell and positioned on the lower part of the tuyere. The utility model fully utilizes the advantages of the cooling wall and the cooling plate, and has the advantages that the cooling unit has good cooling effect and high cooling efficiency, is not easy to damage, can effectively protect the tuyere combined brick and the tuyere device and improves the stability of the bosh part.
Description
Technical field
The utility model relates to the refrigerating unit at a kind of blast-furnace tuyere position, relates in particular to the refrigerating unit of a kind of blast-furnace tuyere band and bosh band junction.
Background technology
Blast-furnace tuyere top is the upper edge of blast furnace hearth, also be the basic place that the bosh position forms, and the bosh bottom is the dropping zone of blast-furnace smelting, the high temperature sludge flowing molten iron that is descended washes away, simultaneously, this position is in the air port zone of combustion again, so this position thermal load surely belongs to first of the whole blast furnace.What adopted at the blast-furnace tuyere position at present is that the monoblock cooling stave carries out the cooling of face formula along the circumferential arrangement of blast furnace, leaves air port equipment during the cooling stave casting passage is installed.This kind methods for cooling has cooling evenly; advantages such as good airproof performance; but the cooling degree of depth is not enough; can only protect tuyere big sleeve; reinforcement along with blast-furnace smelting; the increase of furnace heat load; the circle round expansion of district's scope of air port; the cooling power of cooling wall formula is difficult to meet the demands, and can not effectively protect tuyere brick, and tuyere brick is flowed by coal gas of high temperature in the district of circling round; the slag flowing molten iron; washing away for a long time of the burnt mixture of slag; the life-span of tuyere brick is shorter and shorter; after tuyere brick was etched, cover was exposed in the abominable smelting environment in the air port, causes air port equipment to burn out in a large number; even burning phenomenon all appears in the upper end of air port cooling stave in producing; cause water pipe to break and leak, jeopardize blast furnace hearth safety, on the other hand; after tuyere brick is etched fully; threaten the above position stability of structure of bosh, can cause bosh position furnace shell rubescent when serious; cracking, the safety in production of serious threat blast furnace.
The utility model content
The purpose of this utility model provides a kind of refrigerating unit of blast-furnace tuyere position of good cooling results.
To achieve these goals, adopt following technical scheme:
The refrigerating unit at a kind of blast-furnace tuyere position is characterized in that: described refrigerating unit comprise be fixed on the furnace shell, be positioned at the cooling plate on top, position, air port and be fixed on cooling stave on the furnace shell, that be positioned at bottom, position, air port.
Cooling plate can be one or more layers distribution.
In order to save material, improve the service efficiency of cooling plate, wherein cooling plate is positioned on the above longitudinal direction of air port equipment center line and is not more than the 1.5m scope, the multi-layer intercrossed distribution of cooling plate.
Cooling plate is welded on the furnace shell; Described cooling stave is by being bolted on the furnace shell.
The material of cooling plate and cooling stave is cast steel, cast iron or copper.
The beneficial effects of the utility model are:
Cooling plate is adopted on top, air port, and level is inserted in the stove darker, and the cooling degree of depth is big, the cooling intensity height, the cooling efficiency height, not fragile, under the condition of damaging the also removable advantage of cooling plate; And easy dross, the slag crust difficult drop-off help the protection of tuyere brick, and the existence of tuyere brick is of crucial importance to the safety at air port equipment and bosh position; Under worst situation, after tuyere brick was etched fully, cooling plate still can play a part tuyere brick, continues to keep type of furnace production;
Cooling stave is adopted in the bottom, air port, and cooling is even, and good airproof performance has the protection of overlapping in cooling plate and the air port on it, can guarantee the security of cupola well.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
The refrigerating unit at a kind of blast-furnace tuyere position, this device are included in the last furnace shell the two-layer copper cooling plate 1 of staggered arrangement on the interior longitudinal direction of the above 1.5m scope of air port medullary ray and bottom, the air port circumferential arrangement low-chromium cast-iron cooling stave 2 along blast furnace.The form that is interspersed has been saved the number of cooling plate 1, has saved material, does not influence the refrigerative effect simultaneously again.Copper cooling plate 1 is welded on the furnace shell, and low-chromium cast-iron cooling stave 2 is by being bolted on the last furnace shell.Cooling stave 2 has the cooling channel with cooling plate 1 inside, and water flowing is cooled off.
The utlity model has cooling power by force, not fragile, advantages such as cooling efficiency is high, Stability Analysis of Structures, operation type of furnace rule.
The cooling plate 1 here can be cast steel, cast iron or copper with the material of cooling stave 2, can also be other thermally conductive material also.Cooling plate can be one deck only, also can be multilayer and distributes, and the form of distribution also can adopt other mode.These all drop within the protection domain of the present utility model.
Claims (5)
1. the refrigerating unit at a blast-furnace tuyere position is characterized in that: described refrigerating unit comprises and is fixed on cooling plate on the furnace shell, that be positioned at top, position, air port (1) and is fixed on cooling stave on the furnace shell, that be positioned at bottom, position, air port (2).
2. the refrigerating unit at blast-furnace tuyere as claimed in claim 1 position is characterized in that: described cooling plate (1) is positioned on the above longitudinal direction of air port equipment center line and is not more than the 1.5m scope.
