Description
Technical field
The utility model is related to a kind of maintenance auxiliary tool more particularly to a kind of Blast Furnace Air Mouth Set Relieving Devices.
Background technology
Blast-furnace tuyere device is made of tuyere big sleeve, tuyere medium sleeve and tuyere small sleeve, wherein tuyere medium sleeve and tuyere small sleeve
For copper casting, copper sheathing inside is spiraled cavity formula structure, leads to high-pressure cooling water in cavity, to ensure tuyere medium sleeve and tuyere small sleeve
It can be worked normally in high temperature, hyperbaric environment in cupola well.Since tuyere small sleeve is directly entered in cupola well, working environment is severe,
So tuyere small sleeve is damaged relatively more.And tuyere medium sleeve front position is parallel with furnace wall, so the building ring of tuyere medium sleeve
Border is relatively preferable, and because there is cooling water to be cooled down, in the working of a furnace under normal circumstances, the spoilage of tuyere medium sleeve is much smaller than air port
Small set.Only when thermic load is excessive or cupola well is abnormal, burning damage accident can just occur for tuyere medium sleeve, but quantity is few.
Although the quantity that tuyere medium sleeve damages in use is considerably less, in the air port that annual ironworks is replaced and scrapped
Cover quantity it is very much (by taking 8 seat height stoves as an example, the tuyere medium sleeve quantity averagely replaced and scrapped about at 70-75, wherein there are about
Replaced in a non-damaged condition in two sets of the air port of 60 or so), the tuyere medium sleeve changed directly carries out scrapping processing.
Why needed replacing without damaged tuyere medium sleeveBlast furnace is in normal productive process, due to being subject in stove
The influence of blanking, the variation of gas stream in the stove etc. and misoperation cause to collapse the failures such as hanging, these can all cause two sets of air port
Position change, tuyere medium sleeve is made to upwarp, sink sometimes sometimes, cause blast furnace crucibe surrounding air inlet it is uneven, influence stove
Condition direct motion, it also occur that air port region gas leak.As replaced tuyere medium sleeve not in time, the lighter can influence furnace condition anterograde and reduce production
Amount, severe one is likely to result in furnace condition disorder, as tuyere medium sleeve change in location it is serious when, air port air hose contact can be caused not cause sternly
Leak out in addition can occur burn etc. serious accidents.
Tuyere medium sleeve needs why changing, without breakage are scrappedBecause in dismounting tuyere medium sleeve process
In, the spherical surface that extracting tool contacts tuyere medium sleeve with air port causes damage, therefore has to scrap.Analyze tuyere medium sleeve
Disassembly process to force to disassemble tuyere medium sleeve, employs the hook with sliding hammer as extracting tool, by hook during dismounting
Gib head is hooked to the end face of tuyere medium sleeve, keeps shank horizontal, then quick sliding sliding hammer, using the inertia of sliding hammer, is being rushed repeatedly
It hits and lower disassembles tuyere medium sleeve.In disassembly process steel, harder right-angle hook head with it is made of copper, relatively soft
The end face of tuyere medium sleeve contacts directly, and causes tuyere medium sleeve spherical deformation and cannot use.
If can ensure not damage the spherical surface of tuyere medium sleeve in disassembly process, these disassemble without damage
Tuyere medium sleeve can just reuse, and there is important reality to anticipate the energy-saving work of operating cost and ironworks for controlling blast furnace
Justice.
The content of the invention
The utility model provides a kind of Blast Furnace Air Mouth Set Relieving Device, it can be ensured that in tuyere medium sleeve disassembly process
Its spherical surface with air port cooperation is not damaged, so as to fulfill the recycling without damage tuyere medium sleeve, advantageously reduces production
Cost.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of Blast Furnace Air Mouth Set Relieving Device, including pull rod, drag hook and sliding hammer, drag hook is fixed on pull rod one end, sliding hammer
It is sleeved on pull rod and can be slided along pull rod；The drag hook is J-shaped structure, and long side one end is fixedly connected with pull rod.
Short side one end of the drag hook is equipped with copper or rubber cushion block, and one side and the drag hook of cushion block are bolted,
The contact surface of opposite side and tuyere medium sleeve is plane.
Protective case is equipped on the outside of the drag hook long side, protective case is made of copper or aluminum material.
Compared with prior art, the beneficial effects of the utility model are：
1) drag hook is improved to J-shaped structure by structure of right angle tyoe, so as to avoid the contact with spherical surface, tears tuyere medium sleeve open
Impact part will not damage spherical surface when unloading；
2) drag hook end face adds cushion block, and the hardness of cushion block material is less than or equal to the hardness of copper tuyere medium sleeve, so as to ensure
The tuyere medium sleeve surface of impact site will not damage；
3) rubber protecting jacket is added on the outside of pull rod, prevents that spherical surface is caused to abrade or worn in dismounting.
