Abstract
The invention provides a blast-furnace integral air supply branch pipe device comprising a large flange, an inclined pipe shell, a branch pipe shell, a water-cooling shell, a convex spherical end, an end cover flange, a peephole flange, a peeping device component, a refractory plug and a fireproof material. In the invention, paired flanges in a traditional blast-furnace air supply device are omitted, the branch pipe shell is formed by spinning a seamless steel tube, the internal fireproof material is cast into a whole to thoroughly eliminate the possibility of direct contact between the hot air and the branch pipe shell on structural design and also eliminate the possibility of burnthrough accidents of the air supply branch pipe device with a cracked welding line. The invention has the advantages that the surface temperature of the branch pipe is lowered, the service life of the branch pipe is prolonged, and production cost is decreased.
Description
Technical field
The invention belongs to technical field of blast furnace ironmaking, relate to the air-supply arrangement of blast furnace, especially relate to a kind of all-in-one-piece blowpipe device.
Background technology
As everyone knows, the air-supply arrangement of existing blast furnace includes an elbow and one at least and directly blows arm.This elbow and directly to blow between the arm be to be coupled to each other by a pair of companionflange to become integral body.Because they are separated to make separately, therefore, after they connected by companionflange, at the flange contact facings place, the refractory materials of its inner cast disconnected, and this directly blows a tube shell for the direct contact of hot blast provides structural passage.Especially when directly blowing the arm repeated use, thermal contraction appears being subjected in the refractory materials that directly blows the inner cast of arm, directly blow then expanded by heating of a tube shell, in such cases, directly blowing arm inside, refractory materials will and its housing between form small gap, therefore, hot blast will enter in this gap from this structural passage, make directly to blow tube shell and bear hot blast temperature and rubescent phenomenon occurs.Particularly when directly blowing tube shell and weld cracking occurs, this structural passage will become to bring out and directly blow the inevitable reason that arm burns accident.
Summary of the invention
The present invention proposes a kind of blast furnace monoblock type blowpipe device, it has cancelled the companionflange in the above-mentioned existing air-supply apparatus of blast furnace, make the refractory materials of pouring into a mould in the blowpipe become as a whole, its effect is to eliminate the housing possibility that hot blast directly contacts arm from structure design.
Specific implementation is such: a kind of blast furnace monoblock type blowpipe device is by big flange, inclined tube shell, prop up shell, water-cooled housing, protruding sphere termination, end cap flange, peep hole flange, spy on device assembly, the plug of anti-material the and refractory materials constitutes.Wherein: an end of inclined tube shell is to be connected with big flange, and the other end is and the perforation that crosses of shell; The afterbody that props up shell is sealed by the end cap flange, and its head is to be connected with protruding sphere termination by one section water-cooled housing; On the end cap flange, spy on device assembly and be installed in a shell afterbody by the peep hole flange; In inclined tube shell, a shell and protruding sphere termination, poured into a mould the refractory materials that constitutes hot-air channel; In the hot-air channel of a shell afterbody, embedded one section plug of anti-the material; At the core of this plug of anti-the material, left and spied on passage.
An above-mentioned shell is the whole steel pipe by a weldless steel tube rotary press modelling, no longitudinal weld.
Above-mentioned shell or directly be connected with protruding sphere termination cancelled one section above-mentioned water-cooled housing.This protruding sphere termination or carry a water-cooled cavity, identical with the protruding sphere termination of existing water-cooled.
The above-mentioned plug of anti-the material is and spies on the anti-material of pouring into a mould in the device assembly and constitute one.
Above-mentioned blast furnace monoblock type blowpipe device, the coal spouting gun that is provided with a routine is plugged in the rifle hole.
The invention has the beneficial effects as follows:
(1) the blast furnace monoblock type blowpipe device of the present invention's proposition has been cancelled the companionflange in the existing air-supply apparatus of blast furnace, and a shell is the whole steel pipe by a weldless steel tube rotary press modelling, and its been provided with internal refractories is also poured into as a whole.Therefore, this will thoroughly eliminate the possibility that hot blast directly contacts a shell on structure design, thereby will have eliminated the possibility of bringing out the accident of burning when weld cracking appears in the blowpipe device.
(2) because hot blast can not touch a tube shell, therefore, the present invention is useful to the surface temperature that reduces the blowpipe housing, and is simultaneously also useful to the work-ing life of having improved the blast branch pipe of blast furnace device.
(3) because the present invention has cancelled a pair of companionflange, alleviate the weight of air-supply apparatus of blast furnace, therefore can reduce its manufacturing cost, reduced the replacement charge in the air-supply apparatus of blast furnace production maintenance process.
