Abstract
The utility model relates to a steel cooling stud for a blast furnace, which is characterized in that: the cooling stud comprises a cylindrical steel pipe (2) and a water inlet steel pipe (4), wherein one side of the cylindrical steel pipe (2) is provided with a water outlet steel pipe (8); the cylindrical steel pipe (2) is provided with a cylindrical bottom sleeve (5); both end parts of the cylindrical steel pipe (2) are provided with a front end steel plate (1) and a tail end steel plate (7) with an opening respectively; the cylindrical bottom sleeve (5) is connected with a reinforcing rib plate (6); the water inlet steel pipe (4) is inserted from the opening of the tail end steel plate (7); the water outlet steel pipe (8) is arranged between the reinforcing rib plate (6) and the tail end steel plate (7); and the water inlet steel pipe (4) is provided with a guide vane (3). The steel cooling stud has the characteristics of convenient manufacturing and low cost.
Description
Technical field
The utility model relates to but post of a kind of blast furnace cold, relates in particular to a kind of blast furnace steel cooling stud.
Background technology
Blast furnace generation stove labour enters the middle and later periods and cooling stave will take place damages problem, is exactly the above bosh of cupola well, shaft to be damaged cooling stave change usually and repair in the blast furnace, recovers blast furnace production after building liner again by laying bricks or stones.Therefore be on active service the phase in order to prolong blast furnace, repair in the minimizing or the number of times of light maintenance, people have at first invented and have utilized the copper cooling stud of stove skin boring installation to substitute the local refrigerating function that has damaged cooling stave in the recovery stove, people's but post of blast furnace cold of having developed comparatively economic copper steel one again afterwards, it is whole copper materials that this cooling stud stretches into stove intracutaneous work termination, the stove skin connects water inlet pipe and water outlet pipe outward and partly makes for steel, but its structure exists: the one, because cooling stud shaft copper steel is heterogeneous, strengthen the welding difficulty, though sophisticated copper steel welding technique is arranged at present, cannot say for sure under hot conditions, not take place the weld cracking problem; The 2nd, the termination is whole copper materials, and it is higher relatively to make tooling cost; The 3rd, this cooling stud water outlet does not have any type of guiding device (having cut saw dissection confirmation to damaging cooling stud), and it is serious to go out the water turbulence phenomenon, has influenced cooling performance.
The utility model content
Technical problem to be solved in the utility model provide a kind ofly be convenient to make, blast furnace with low cost steel cooling stud.
For addressing the above problem, a kind of blast furnace steel cooling stud described in the utility model is characterized in that: this cooling stud comprises that a side is provided with the cylinder steel pipe and the water inlet steel pipe of water outlet steel pipe; Described cylinder steel pipe overlaps at the bottom of being provided with cylinder, and its end is respectively equipped with the tail end steel plate of front end steel plate and band perforate; Put at the bottom of the described cylinder and be connected with the reinforcement gusset; Described water inlet steel pipe inserts from the tapping of tail end steel plate; Described water outlet steel pipe is located between described reinforcement gusset and the described tail end steel plate; Described water inlet steel pipe is provided with guide vane.
Described guide vane is straight-plate type or spiral type blade.
Interplanar distance is the diameter dimension of described water inlet steel pipe in the effluent pipe mouth of described water inlet steel pipe and the described front end steel plate.
Cover is positioned at 1/3～1/4 cylinder steel pipe place near described tail end steel plate at the bottom of the described cylinder.
The utility model compared with prior art has the following advantages:
1, because the utility model adopts all steel material to make, reduced the welding difficulty, it is minimum that weld seam reaches, so the cooling stud globality is good.
2, because the utility model according to cylinder length, has designed spiral type and straight two kinds of guiding devices of plate flow guiding type to the water outlet of cooling stud, it is smooth and easy therefore to help current, has avoided the generation of turbulent phenomenon.
3, since the utility model omitted peripherally uniform beat the mud chamber, the hole is designed, make processing and fabricating efficient quick more, can be delivered for use owing to the utility model only needs to control and suppress test passes by the container weldprocedure simultaneously, therefore be convenient to very much each Steel Plant and independently complete.
4, the utility model is installed in position, shaft middle and upper part, i.e. the interior solid material position of blast furnace and initially cohesive zone position, its opposing decline furnace charge friction and rising dust-laden coal gas flow performance of flushing and all are better than copper cooling stud; Even be installed in restoration of lower stack up to the bosh position, guarantee that water temperature difference in setting range, not only can form slag crust layer stably, also help and prevent that incrustation scale from generating.
5, cost of manufacture is cheap: March in 2008, wine steel on the 31st 6# blast furnace maintenance was installed 81 of steel making cooling studs in stack stave 7,8 fragment position, thereafter in 4,5 monthly repairs, in 4#, 6# blast furnace stack cooling stave 6,7,8 fragment position steel are installed respectively again and are made each 80 of cooling studs, two blast furnaces have been installed 251 altogether.The 6# blast furnace has 1 to be burnt out at present, is equipped with 18 in 6# blast furnace 7,8 fragment position in January, 2008 and introduce copper steel one cooling stud, is burnt out by having 2 by the end of May.800 yuan/of the inner valencys of self-control steel cooling stud, and 5000 yuan/of outsourcing copper sheet cooling studs, alternative buying is economized on the use of funds about 105.42 ten thousand yuan.
