Abstract
The utility model discloses a convex platform inclined cooling wall for blast furnaces, composed of a convex platform 1, a cooling wall body 2 and a cooling water tube 3. The included angle theta of the convex platform 1 and the cooling wall body 2 is 91-98 DEG; the convex platform 1 is also provided with a third cooling water tube 4 which has an independent cooling tube system from the cooling water tube 3. The convex platform structure of the utility model can overcome the problem that the inner lining bricks of blast furnaces collapse to fall down, and thus the service life of blast furnaces is prolonged. Compared with the latest cooling wall technology used at present, the utility model can prolong the service life of blast furnace about 2 years.
Description
The utility model belongs to the blast furnace parts, relates in particular to the blast furnace furnace wall refrigerating unit.
Blast furnace furnace wall not only will bear high temperature aborning, also will stand erosive wear, and working conditions is very abominable.In order to prolong the work-ing life of blast furnace furnace wall, often on the shaft of blast furnace, cooling stave is housed, pass to water coolant in it, to reduce the temperature of bricking, keep the intensity and the wear resistance of bricking.The length that the boss of the present up-to-date cooling stave that uses on blast furnace both at home and abroad stretches out the cooling wall body is 250～300mm, and two water-cooled tubes are established in the complete horizontal setting of boss in boss.This cooling stave is poor to the supporting capacity of bricking in the blast furnace.Occur the bricking instability in the actual production, very easily cause bricking to collapse to fall, influence the work-ing life of blast furnace.
The purpose of this utility model is to improve at the problem that existing cooling stave exists, to improve cooling stave to the supporting capacity of bricking and the stability of raising bricking.
To achieve these goals, the scheme that the utility model adopted is, cooling stave is made up of boss 1 cooling wall body 2 and water-cooled tube 3, boss 1 is 91～98 ° with the angle theta of cooling wall body 2, the 3rd water-cooled tube 4 also is housed on boss 1, and water-cooled tube 4 is independently to cool off piping respectively with water-cooled tube 3.
Adopt effect of the present utility model:
Because boss structure of the present utility model can overcome the problem that falls that collapses of bricking in the blast furnace, therefore can prolong blast furnace work-ing life.Compare with the up-to-date cooling stave technology of present use, can prolong about the 2 years work-ing life of blast furnace.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 cooling stave front view
Fig. 2 cooling stave side-view
Fig. 3 embodiment of the present utility model
One of embodiment of the present utility model is the middle part that boss 1 is located at cooling wall body 2, and its angle theta is 93 °.
The utility model compared with prior art, boss with respect to the cooling wall body distance obviously lengthen. Make the refractory material of cooling wall top all be positioned at the boss range.
Claims (2)
1, a kind of boss cooling stave of section that inclines, it is made up of boss (1), cooling wall body (2) and water-cooled tube (3), it is characterized in that the boss (1) and the angle of cooling wall body (2) are 91～98 °, the 3rd water-cooled tube (4) also is housed on boss (1), and water-cooled tube (4) is independently to cool off piping respectively with water-cooled tube (3).
2, cooling stave according to claim 1 is characterized in that, boss (1) is 93 ° with the angle of cooling wall body (2), and the 3rd water-cooled tube is housed on boss (1).
