Abstract
The utility model provides an improved generation blast furnace electro thermol bed, includes top brick body structure, top brick body structure is laid bricks the layer by inside and is makeed firm by ramming with the outside and layer constitute, it is equipped with condenser tube to make the in situ firm by ramming. Utilize the utility model discloses can effectively solve the problem that the electro thermol bed top brick body easily sinks, electro thermol bed improves back life to be increased to 2 years from 10 months, can guarantee the continuous stable production of blast furnace.
Description
Technical field
This utility model is related to a kind of modified model blast furnace electrothermal front bed.
Background technology
Existing blast furnace electrothermal front bed, as shown in figure 1, it mainly by upper and lower two parts brick construction and encloses brick and constitutes,
Upper and lower two parts brick construction is identical, and using two-layer brick arch, internal layer is vertical brick, and outer layer is flat brick.Which has the drawback that：
Technique of laying bricks at the top of electrothermal front bed load-bearing, temperature resistant capability are poor, easily subside, and the continuous production of blast furnace is restricted.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and can effectively prevent roof collapse, it is ensured that blast furnace
The modified model blast furnace electrothermal front bed of continuous and stable production.
This utility model is solved and its technical scheme that adopted of technical problem is：Before a kind of modified model blast furnace electric heating
Bed, including top brick laying structure, the top brick laying structure is laid bricks layer by inside and outside is made layer firm by ramming and constituted, described to make firm by ramming in layer
It is provided with cooling water pipe.
Further, the cooling water pipe is snakelike cooling water pipe.
Further, described making firm by ramming be provided with layer steel skeleton.
Further, the steel skeleton is in netted.
Further, the steel skeleton is screw thread steel skeleton.
Using the givey problem of brick body at the top of this utility model energy effectively solving electrothermal front bed, electrothermal front bed is made after improving
2 years were increased to from 10 months with the life-span, it is ensured that the continuous and stable production of blast furnace.
Description of the drawings
Fig. 1 is the structural representation of existing blast furnace electrothermal front bed；
Structural representations of the Fig. 2 for this utility model embodiment；
The structural representations of making layer of the Fig. 3 for embodiment illustrated in fig. 2.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Reference picture 2- Fig. 3, the present embodiment include top brick laying structure, and the top brick laying structure is laid bricks 1 He of layer by inside
Outside is made layer 2 firm by ramming and is constituted, and described making firm by ramming in layer 2 is provided with cooling water pipe 3.
In the present embodiment, the cooling water pipe 3 is snakelike cooling water pipe.
In the present embodiment, described making firm by ramming in layer 2 is provided with netted screw thread steel skeleton 4.
This utility model adds layer of laying bricks using making layer firm by ramming, both can effectively reinforce intensity at the top of external crucible, prevents top from laying bricks knot
Structure subsides, and ensures that the service life and heat insulation effect of external crucible.
Intensity of the present utility model and resistance to elevated temperatures are excellent, and the heat stability for making layer and internal brick body firm by ramming is good.
