Abstract
The utility model relates to the technical field of a blast furnace with long service life, in particular to a novel tuyere zone cooling wall. The tuyere zone cooling wall is characterized in that a binding face of the tuyere zone cooling wall connected with a blast furnace shell is a curved surface structure, the cooling wall tightly contacts with the blast furnace shell after the cooling wall is installed, and a heat-resistant resinous sealing gluing layer is arranged between the cooling wall and the blast furnace shell in a smearing mode. The thickness of the sealing gluing layer is 3 millimeters to 5 millimeters. Compared with the prior art, the novel tuyere zone cooling wall can effectively avoid water leaking into a blast furnace bottom and the inner portions of a furnace cylinder carbon bricks caused by damage and leakage of a cooling device so as to relieve a corrosion progress of a furnace lining carbon bricks, and prolong the service life of the blast furnace cylinder and furnace bottom. The novel tuyere zone cooling wall has the advantages of being low in investment and convenient to operate, and has a considerable economic benefit.
Description
Technical field
The utility model relates to the long-lived technical field of blast furnace, relates in particular to a kind of novel tuyere-belt cooling wall.
Background technology
A lot of hearth breakout accidents occur in recent year many large blast furnaces successively, and these blast furnaces have also all adopted long-lived complex art, but effect is unsatisfactory, and indivedual blast furnaces are gone into operation less than the hearth breakout accident namely occured in 3 years.Traditional air port cooling wall structure pattern is, the cooling stave at corresponding cooling water inlet pipe and rising pipe place is respectively equipped with the thick boss of 30mm, and the cooling stave at standing bolt place is provided with the thick boss of 40mm, and during installation, smash into filler in the slit between cooling stave and furnace shell.When the cooling stave water pipe is damaged, water coolant washes away filler from top to bottom, enlarged gas flue, blast furnace gas is carrying basic metal and Zn infiltrates cupola well brick fuel slit, leak and brick fuel generating gasification reactive etching brick fuel, basic metal and the deteriorated brick fuel performance of Zn meeting, affect the bottom hearth of blast furnace life-span.
Summary of the invention
The purpose of this utility model is to provide a kind of novel tuyere-belt cooling wall, and the water that leakage produces when weakening the cooling stave damage and blast furnace gas prolong the bottom hearth of blast furnace life-span to the damage effect of tuyere equipment.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of novel tuyere-belt cooling wall, its binding face that is connected with furnace shell is curved-surface structure, after cooling stave is installed, cooling stave and furnace shell close contact, the sealant layer of application fire resistant resin between cooling stave and the furnace shell.
Described seal gum bed thickness 3-5mm.
Compared with prior art, the beneficial effects of the utility model are: owing to the assemblage gap that has reduced between cooling stave and furnace shell, effectively avoid cooling apparatus to damage the water that leaks generation and enter furnace bottom and cupola well brick fuel inside, thereby alleviated the process of deteriorating of furnace lining brick fuel, prolonged life-span of blast furnace hearth, furnace bottom, have less investment, easily the advantage of constructing operation has considerable economic benefit.
Description of drawings
Fig. 1 is that the utility model improves structural representation.
Among the figure: 1-cooling stave water pipe 2-standing bolt 3-furnace shell 4-cooling stave 5-sealant layer
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, that a kind of novel tuyere-belt cooling wall of the utility model improves structural representation, its binding face that is connected with furnace shell 3 is curved-surface structure, cancelled the boss at present corresponding cooling stave water pipe 1 place and standing bolt 2 places, in the installation of cupola well cooling stave, make cooling stave 4 and furnace shell 3 close contacts, and between cooling stave 4 and furnace shell 3 sealant layer 5 of application fire resistant resin, it is mobile to cupola well and iron oral region to stop that cooling apparatus leaks the water that produces; Sealant layer 5 thick 3-5mm.
Claims (2)
1. a novel tuyere-belt cooling wall is characterized in that, its binding face that is connected with furnace shell is curved-surface structure, after cooling stave is installed, and cooling stave and furnace shell close contact, the sealant layer of application fire resistant resin between cooling stave and the furnace shell.
2. a kind of novel tuyere-belt cooling wall according to claim 1 is characterized in that, described seal gum bed thickness 3-5mm.
