Description

The invention relates to a cooling arrangement for blast furnaces by sprinkling the furnace shell.

The cooling of a blast furnace in the area of the furnace shell in the Rast and lower Schachtdereici. are in »Ρ ο c h w i s η e w, The blast furnace operation, page 510 and 466, Fig. 174 ”and in“ P a w I ο w, Metallurgy des Roheisens, Volume II, pages 185 and 187 «. The known cooling arrangements have disadvantages afflicted that make uniform cooling difficult or impossible. So sit z. B. the The outflow openings of the funnel-shaped cooling water tank (see page 187, Fig. 172) are slightly closed, see above that the cooling water runs off ineffectively when it overflows.

It is also known to cool the entire armor using spray strips and fringes. Here is «A quantity of the cooling water is sprayed off or diverted by the cooling boxes, so that a very high water consumption with uneven cooling and impairment of the environment by the sprayed cooling water ^ entry To eliminate these disadvantages, a double jacket cooling (DT-AS 20 50443) is proposed been. This design is very complex and can not or only due to the closed design be controlled with considerable effort.

In previously known cooling systems, frequent clogging of the nozzles resulted in an even flow Cooling of the outer armor, especially in the dead flow spaces under the cooling boxes, is not guaranteed

It is the object of the invention to provide a cooling arrangement for To create blast furnaces that uniform cooling of the armor or the masonry between the Cooling boxes guaranteed with simple means and the largely avoids the disadvantages described above,

To achieve this object a cooling arrangement for blast furnaces in the region of, the furnace tank in the catch and at the lower Schachtbcreich is proposed erflndungsgemäß which is characterized known by at obliquely on the tank directed cooling water bags, which are sealed at aer joint over its entire length and üirer at the upper edge _((J outer wall are provided with means which allow a defined and determined in the direction of outflow of the cooling water as the direction directing agent for the cooling water means disposed on the outer wall under prestress elastic <is:. bar suggested that such The individual cooling pockets are offset between and below the cooling boxes protruding into the refractory lining.

The inventive arrangement is a Prevents clogging of the outlet openings. The in Impurities in the cooling water settle

partly on the sealed bottom of the cooler bags

from or are through the large recesses in the

'Flushed out elastic bar. The cooling water flows

by pulling out over the rear wall

Defined recesses of the prestressed strips

and is picked up again by the offset, lower-lying cooler bags.

One possible embodiment of the cooling arrangement according to the invention is shown schematically in the drawings shown.

Show it:

F i g. 1 shows a cross section through a cooling bag on the line A -A of FIG. 3,

F i g. 2 shows a cross section through a cooling bag on the line £ -ß of Fig. 3,

3 shows a front view of the cooling bag from the direction X, see FIG. 2,

F i g. 4 a part of the overall arrangement in view.

In Fig. 1 and 2 are the cooling bags, consisting of the side walls 1 and the outer wall 2, welded to the armor 3 and sealed downwards over their entire length with a sealing compound 4 elastic bar 6 provided. The elastic bar 6 is fastened on both sides by screws 7 and protrudes with its lugs ii over the outer wall 2 of the cooling bag in such a way that the recesses 9 of the bar 6 serve as drainage openings for the cooling water.

In F ϊ g. 3 is the way in which the bar 6 is fastened the outer wall 2 shown The overall arrangement of the cooling bags 10, which are offset between or below the cooling box 11 is welded on is shown in FIG

The inventive arrangement is a Defined and in the direction of certain drainage of the cooling water allows, with the area under the Cooling box is fully included in the cooling.
