Abstract
A blast-furnace novel tuyere-belt cooling wall comprises: a tuyere-belt cooling wall body, a tuyere-belt cooling wall water cooling pipe, a water cooling pipe protection sleeve, a water cooling pipe protection sleeve seal annular pad, a tuyere-belt cooling wall hanging ring and a protection asbestos rope, characterized in that: the tuyere-belt cooling wall has a thin lower part, a thick middle part and a thin upper part. A fillet is formed at the cross part between a top surface of the tuyere-belt cooling wall and a hot surface. The bend radius of the tuyere-belt cooling wall water cooling pipe is arranged at the top of the tuyere-belt cooling wall is two times of the diameter of the tuyere-belt cooling wall water cooling pipe. The cooling wall uses cast iron or cast steel or copper material and the cooling wall water cooling pipe uses a steel pipe or a copper pipe. The thickness of the front brick liner at the upper part of the tuyere-belt cooling wall is obviously thickened and the stability of the brick liner is reinforced, thus the upper part of the tuyere-belt cooling wall and the lower part of the bosh copper cooling wall cross at the cold surface and the tuyere-belt cooling wall is effectively protected and the damage on the tuyere-belt cooling wall is reduced, therefore the service life of the blast-furnace is increased and the blast-furnace novel tuyere-belt cooling wall is suitable for cooling the tuyere-belt of the blast-furnace.
Description
Technical field
The utility model relates to blast-furnace smelting equipment, particularly relates to big-and-middle-sized blast-furnace tuyere band cooling stave.
Background technology
Current; domestic big-and-middle-sized blast furnace generally adopts the structure formation of the thin full cooling stave of liner; because liner attenuate; tuyere zone cooling stave and bosh band copper cooling wall junction are to the blast furnace off centering; the elevated temperature heat load that bear at this place increases; what existing blast-furnace tuyere band cooling stave adopted is bottom thin; the thick structure formation in top, middle part; cause the anterior protection of tuyere zone cooling stave bricking attenuate; the hot side of tuyere zone cooling stave top and bosh band copper cooling wall bottom intersects; make the intersection of tuyere zone cooling stave be subjected to thermal conditions very poor; be easy to generate crackle and damage cooling stave, influence blast furnace campaign.
Summary of the invention
The purpose of this utility model is the problem that exists at above-mentioned existing tuyere zone cooling stave, and a kind of damage that reduces tuyere zone cast iron wall is provided, and improves the novel tuyere zone cooling stave of blast furnace campaign.。
The technical solution of the utility model is: comprise tuyere zone cooling stave wall body, tuyere zone preparing water cooling pipe for cooling wall, water cooling tube protective casing, water cooling tube protective casing sealing ring pad, tuyere zone cooling stave suspension ring, protection asbestos twine, it is characterized in that tuyere zone cooling stave (1) wall thickness is the structure formation that bottom thin, middle part are thick, top is thin.
The end face (6) of described tuyere zone cooling stave wall body (1) and hot side (7) intersection rounding.
Described tuyere zone preparing water cooling pipe for cooling wall (5) bending radius that is positioned at tuyere zone cooling stave (1) top is the twice of tuyere zone preparing water cooling pipe for cooling wall 5 diameters.
Described cooling stave wall body (1) adopts cast iron or cast steel or copper material, and preparing water cooling pipe for cooling wall (5) adopts steel pipe or copper pipe.
The beneficial effects of the utility model are: tuyere zone cooling stave top thin thickness; can significantly thicken the thickness of the preceding bricking of tuyere zone cooling stave; strengthened the stability of bricking; can also make tuyere zone cooling stave top and bosh copper cooling wall bottom intersect at huyashi-chuuka (cold chinese-style noodles); thereby strengthen tuyere zone cooling stave cooling protection; reduce the damage of tuyere zone cooling stave, improve blast furnace campaign.The end face of tuyere zone cooling stave and hot side intersection rounding reduce the internal stress of tuyere zone cooling stave, improve the inner quality of tuyere zone cooling stave, improve blast furnace campaign.The tuyere zone preparing water cooling pipe for cooling wall bending radius at tuyere zone cooling stave top is the twice of tuyere zone preparing water cooling pipe for cooling wall diameter, can effectively improve the water cooling tube bending quality, reduces the water cooling tube damage, prolongs the cooling stave life-span, improves blast furnace campaign.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is to use tuyere zone and bosh band junction structural representation behind the utility model.
1. tuyere zone cooling stave wall bodies, 2. tuyere zone cooling stave suspension ring, 3. water cooling tube protective casing among the figure; 4. water cooling tube protective casing sealing ring pad, 5. tuyere zone preparing water cooling pipe for cooling wall, 6. end face; 7. hot side, 8. big thickness protection bricking, 9. the bosh band copper cooling wall huyashi-chuuka (cold chinese-style noodles) before the tuyere zone cooling stave.
Embodiment
As shown in Figure 1; comprise tuyere zone cooling stave wall body (1), cooling stave suspension ring (2), water cooling tube protective casing (3), protective casing sealing ring pad (4), tuyere zone preparing water cooling pipe for cooling wall (5), protection asbestos twine, tuyere zone cooling stave (1) wall thickness is the structure formation that bottom thin, middle part are thick, top is thin.
The end face (6) of tuyere zone cooling stave (1) and hot side (7) intersection rounding reduce the cold internal stress of tuyere zone, to avoid or to slow down the generation of tuyere zone cooling stave top crackle.
Tuyere zone cast-iron cooling wall water cooling tube (5) bending radius that is positioned at tuyere zone cast-iron cooling wall (1) top is the twice of water cooling tube diameter.And prior art only is 1.5 times, and the structure after the improvement can reduce the water pipe damage, thereby prolongs the cooling stave life-span.
Tuyere zone cooling stave wall body (1) adopts cast iron, and preparing water cooling pipe for cooling wall (5) adopts steel pipe.
As shown in Figure 2, behind use the utility model, can significantly thicken the thickness of the preceding bricking of tuyere zone cooling stave, strengthen the stability of bricking, strengthen protection the tuyere zone cast-iron cooling wall.Make tuyere zone cooling stave top and bosh copper cooling wall bottom intersect at huyashi-chuuka (cold chinese-style noodles) (9) simultaneously, thereby strengthen tuyere zone cooling stave cooling protection is reduced the damage of tuyere zone cooling stave.
Therefore, behind use the utility model tuyere zone cooling stave, can improve the heat distribution situation of the junction of tuyere zone cooling stave and bosh band copper cooling wall, more help protection and cooling, thereby improve blast furnace campaign the tuyere zone cooling stave.
