Abstract
The utility model discloses a kind of blast-furnace bosh cupola well junction cooling wall protection structure of technical field of blast furnace ironmaking, the problem of to solve erodible current blast-furnace bosh cupola well junction, short life.It includes the bosh cooling wall wall body and cupola well cooling wall wall body that inside is embedded with cooling water pipe; bosh cooling wall wall body and cupola well cooling wall wall body junction leave gap; filling fire resisting material in gap; bosh cooling wall wall body and cupola well cooling wall wall body junction extend to form boss to huyashi-chuuka (cold chinese-style noodles) respectively; groove is respectively equipped with two boss huyashi-chuuka (cold chinese-style noodles); two legs of groove profile guard member are embedded in two boss grooves respectively, and the huyashi-chuuka (cold chinese-style noodles) direction in gap is sealed.The utility model junction above and below cooling wall huyashi-chuuka (cold chinese-style noodles) adds boss respectively; add the distance that coal gas or slag iron are scurried out; groove profile guard member is additionally arranged on boss simultaneously; it can effectively stop that coal gas or slag iron are scurried out from gap and burn out the cooling wall water pipe of huyashi-chuuka (cold chinese-style noodles), improve the service life of cooling wall.
Description
Technical field
The utility model is related to a kind of blast-furnace bosh cupola well junction cooling wall protection knot of technical field of blast furnace ironmaking
Structure.
Background technology
Blast furnace cooling stave is played an important role in blast furnace cooling system or even whole blast furnace iron-making process, cooling wall
Normal operation is the important guarantee of prolonging campaign and blast furnace stable smooth operation.Blast furnace cooling stave working environment is severe, not only to bear
High temperature, the erosion of abrasion, slag iron and washing away for Gas Flow also subject to furnace charge.Although researcher is to the material of blast furnace cooling stave
Substantial amounts of research has been carried out in terms of matter, properity, but the life-span that China repaiies in many blast furnace generation furnace life without at present is less than
10 years, only seldom blast furnace can realize that the life-span that generation furnace life repaiies without in reaches more than 15 years.The life of the blast furnace, integral level was with setting
Meter target has a certain distance.
Production practices show, have many cooling walls damage not be from hot face by high-temperature coal air-flow or slag iron scaling loss, but
High-temperature coal air-flow or slag iron are scurried out from the gap of cooling wall junction above and below blast-furnace bosh cupola well burns out the cooling wall water of huyashi-chuuka (cold chinese-style noodles)
Pipe, so as to cause cooling wall to damage.Although the gap at the cooling wall place of being vertically connected with all is filled by refractory material during construction, due to
Protection in structure is not enough, and after filler suffers erosion, high-temperature coal air-flow or slag iron are easily scurried out at gap.Blast furnace cooling stave
The safety in production of badly broken threat blast furnace, when especially badly broken is repaiied in needing, considerably increases production cost.Therefore,
It is necessary to be improved bosh cupola well junction cooling wall structure, hinders the gap of shelves high-temperature coal air-flow or slag iron from junction
Scurry out, slow down cooling wall breakage, extend its service life.
Utility model content
The purpose of this utility model is to overcome prior art defect to cool down there is provided a kind of blast-furnace bosh cupola well junction
Wall protection structure, to extend blast furnace cooling stave service life.
What the technical solution of the utility model was realized in：A kind of blast-furnace bosh cupola well junction cooling wall protection knot
Structure, including the internal bosh cooling wall wall body and cupola well cooling wall wall body, bosh cooling wall wall body and cupola well for being embedded with cooling water pipe
Cooling wall wall body junction leaves filling fire resisting material in gap, gap, and it is, bosh cooling wall wall body and cupola well cooling
Wall wall body junction extends to form boss to huyashi-chuuka (cold chinese-style noodles) respectively so that bosh cooling wall wall body and cupola well cooling wall wall body convergence part
The refractory masses filled in position gap and gap also accordingly extend, and groove, groove profile protection are respectively equipped with two boss huyashi-chuuka (cold chinese-style noodles)
Two legs of part are embedded in two boss grooves respectively, and the huyashi-chuuka (cold chinese-style noodles) direction in gap is sealed.
The utility model junction above and below cooling wall huyashi-chuuka (cold chinese-style noodles) adds boss respectively, extends gap length, so that
The distance that coal gas or slag iron are scurried out is added, while being additionally arranged groove profile guard member on boss, can effectively stop coal gas or slag
Iron is scurried out from gap burns out the cooling wall water pipe of huyashi-chuuka (cold chinese-style noodles), improves the service life of blast furnace cooling stave, it is ensured that the stabilization of blast furnace
Direct motion.

Part.
Embodiment
It is further described below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of blast-furnace bosh cupola well junction cooling wall protection structure, including inside are embedded with cooling water pipe
3 wall body of bosh cooling wall 1 and the wall body of cupola well cooling wall 2, the wall body of bosh cooling wall 1 and the wall body junction of cupola well cooling wall 2
Leave filling fire resisting material in gap 4, gap 4, the wall body of bosh cooling wall 1 and the wall body junction of cupola well cooling wall 2 respectively to
Huyashi-chuuka (cold chinese-style noodles) extends to form boss 5 so that in the wall body of bosh cooling wall 1 and the wall body junction gap 4 of cupola well cooling wall 2 and gap 4
The refractory masses of filling also accordingly extend, so as to add the distance that coal gas or slag iron are scurried out, on two huyashi-chuuka (cold chinese-style noodles) of boss 5 respectively
Provided with groove, two legs of groove profile guard member 6 are embedded in the groove of two boss 5 respectively, and the huyashi-chuuka (cold chinese-style noodles) direction in gap 4 is sealed
Firmly, it can effectively stop that coal gas or slag iron are scurried out from gap 4 and burn out the cooling water pipe 3 of huyashi-chuuka (cold chinese-style noodles), improve making for blast furnace cooling stave
With the life-span, it is ensured that the stable smooth operation of blast furnace.Boss 5 and cooling wall are integral structures, and guard member 6 should select fusing point high, anti-
The preferable material of thermal shock performance, it is optional to be processed with cooling wall identical material.
