Description
Technical field
This utility model relates to a kind of blast furnace taphole cooling wall that can carry out integral replacing, belongs to blast furnace taphole equipment skill
Art field.
Background technology
Blast furnace taphole cooling wall is the key position of blast furnace, and ferrum mouth is safeguarded playing vital effect, once because
A variety of causes causes damage, should change in time, the most easily causes production accident, as the blast of ferrum mouth and ferrum mouth burn.Conventional
Replacing way be use level-lowering blowing out method, take off furnace rear from inside, to the cupola well resistance to material of ferrum port part remove, cold to ferrum mouth afterwards
But wall is replaced.The shortcoming of this method is that shutdown maintenance time length, maintenance cost are high, big on the impact produced.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can be with the ferrum mouth cooling wall of integral replacing, this ferrum
Mouthful cooling wall can not level-lowering, reduce the damping down time, quick, safe and environment-friendly, be replaced efficiently.
The technical scheme solving above-mentioned technical problem is:
A kind of can be with the ferrum mouth cooling wall of integral replacing, it includes on the left of taphole frame, ferrum mouth cold on the right side of cooling wall and ferrum mouth
But wall, on the left of ferrum mouth, on the right side of cooling wall and ferrum mouth, cooling wall lays respectively at taphole frame both sides, and it also has annular furnace shell, annular furnace shell
The outside surrounding of inside edge and taphole frame be welded to connect, cooling wall and taphole frame on the right side of cooling wall and ferrum mouth on the left of ferrum mouth
Both sides and upper end, lower end are welded to connect, and the neighboring of annular furnace shell is connected with body of heater furnace shell.
Above-mentioned can divide equally inside cooling wall on the right side of cooling wall, ferrum mouth on the left of ferrum mouth with the ferrum mouth cooling wall of integral replacing
Outside cooling water pipe and inner side cooling water pipe are not installed.
The beneficial effects of the utility model are:
This utility model welds lower online for cooling wall on the right side of cooling wall, ferrum mouth on the left of annular furnace shell, taphole frame and ferrum mouth,
The formula that is combined into one ferrum mouth cooling wall.Available blast furnace interior damping down servicing machine meeting in 72 hours, to two pieces of on-the-spot ferrum mouth coolings
Wall carries out integral replacing after extracing and is in the milk, it is achieved Quick overhaul.And every piece of cooling wall is respectively by inside and outside two cooling water
Pipe cools down, and after side cooling water pipe is damaged, opposite side cooling water pipe can also maintain the cooling of 30%-50% strong
Degree, gains time to integral replacing.
This utility model simple in construction, easy to operate, ferrum mouth cooling wall can be carried out integral replacing, stop ferrum mouth cold
But cornice disease dangerous operation and energetically abatement level-lowering blowing out from inside change ferrum mouth cooling wall high cost, change operation permissible
Not level-lowering, reduces maintenance time, and Renewal process is quick, safe and environment-friendly, efficient, does not interferes with being smoothed out of production, has
Significantly economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is installation site schematic diagram of the present utility model.
In figure, labelling is as follows: cooling wall 3 on the right side of cooling wall 2, ferrum mouth on the left of annular furnace shell 1, ferrum mouth, outside cooling water pipe 4,
Inner side cooling water pipe 5, taphole frame 6, lifting nose 7, grout hole 8, the mouth of a river 9, fastening bolt 10, tap drain 11, ferrum mouth centrage 12,
Body formula ferrum mouth cooling wall 13, body of heater furnace shell 14.
Detailed description of the invention
This utility model is cold by cooling wall 3 on the right side of cooling wall 2, ferrum mouth on the left of annular furnace shell 1, ferrum mouth, taphole frame 6, outside
But water pipe 4, inner side cooling water pipe 5 form.
Showing in figure, the outside surrounding in taphole frame 6 is welded with annular furnace shell 1, on the left of ferrum mouth on the right side of cooling wall 2 and ferrum mouth
Cooling wall 3 lays respectively at taphole frame 6 both sides, on the left of ferrum mouth on the right side of cooling wall 2 and ferrum mouth cooling wall 3 and taphole frame 6 both sides and
Upper end, lower end are welded to connect, the formula that is combined into one ferrum mouth cooling wall 13, and the periphery of annular furnace shell 1 is connected with body of heater furnace shell 14.
Figure shows, cooling water in outside is installed inside cooling wall 3 on the right side of cooling wall 2, ferrum mouth on the left of ferrum mouth respectively
Pipe 4 and inner side cooling water pipe 5.Every piece of cooling wall is cooled down by inside and outside two water pipes, after side cooling water pipe is damaged,
Opposite side cooling water pipe can also maintain the intensity of cooling of 30%-50%, gains time to integral replacing.
Replacing operation process of the present utility model is as follows:
First the formula that is assembled into one before damping down ferrum mouth cooling wall 13, chooses annular furnace shell 1 according to old ferrum mouth cooling wall
Size, accomplishes fluently 45 degree of grooves by annular furnace shell 1 thickness surrounding, assembles taphole frame 6, install cooling wall 2 and Tie Kou on the left of ferrum mouth
Right side cooling wall 3.
Next utilizes damping down chance, the partial demolition contacted with body of heater furnace shell 14 by tap drain 11, find ferrum mouth cooling wall with
The gap location of the adjacent cooling wall of surrounding, with gas welding lower part body of heater furnace shell 14 at surrounding gap, utilizes stokehold overhead traveling crane to coordinate
Guide chain entirety is extractd, and before extracing, taphole frame 6 is carried out telltale mark.Body of heater furnace shell 14 after cutting off is accomplished fluently 45 by furnace shell thickness
Degree groove.Material resistance at ferrum mouth is suitably cleared up according to damaged condition.
According to telltale mark, Integral iron mouth cooling wall 13 is installed afterwards, in outside, new and old furnace shell is welded, it is desirable to
Through welding, weldering meat is enough.After welding, ferrum mouth is carried out formwork and pours, and on new furnace shell, carry out perforate grouting, after being dried upper intensity
Form removal.Finally recover the tap drain part removed.
This utility model is particularly suited for dischargeable capacity 500m3Following blast furnace casting operation.
