Abstract
Instant invention overcomes the deficiency that prior art is present, there is provided the method for impurity in a kind of blast furnace cooling stave removal pipe, it is simple to operate, low cost, it is time saving and energy saving, it is prevented effectively from scrapping for casting, steel ball is positioned in the water pipe of blocking from one end of water pipe, when a steel ball is fallen into pipe, first can be blocked by firm impurity thing, and the mouth of pipe is gradually overflowed by steel ball, now steel ball is impacted with hand hammer, make first steel ball that the effect of thrust is produced to impurity thing, constantly in impact, impurity thing is set to come off, then steel ball is ejected successively from other end stone dead wire, it is last to do logical ball experiment and the water pressure test again, ensure that casting is qualified.
Description
Technical field
The method of impurity in a kind of blast furnace cooling stave removal pipe of the present invention, and in particular to after blast furnace cooling stave casting,
There are impurity, the logical ball index of influence, the side of impurity in a kind of removal pipe used in the case of conventional method is indeterminable in pipe
Method.
Background technology
Need to set cooling wall in the furnace wall of blast furnace, cooling wall is by rectangle fragment of brick and is cast into the cold of its internal bending
But water pipe is constituted.During cooling, by being realized to cooling water is injected in water pipe, and cooling effect is then length, the energy by water pipe
Enough determined by the water velocity size of water pipe and the service life length of cooling water pipe.It is placed in the length of rectangle fragment of brick reclaimed water pipe
Degree is more long, bigger by the flow velocity of water pipe reclaimed water and service life of water pipe is more long, and the effect for cooling down is then better, on the contrary meeting
It is poor.
And the important indicator of cooling wall detection is logical ball inspection and pressure testing inspection, and logical ball experiment directly affects the water of water pipe
Flow velocity degree, in production process, then impact and cladding of the water pipe by molten iron be cooled to normal temperature, and water pipe is heated oxygen in the process
Change and produce oxide skin to come off, if blowing clean not in time, treat that water blows unclean in follow-up suppress pipe, can form precipitation, influence is logical
Ball is checked, and this is one.The second is in cooling wall casting process, thering is molten iron to splash in pipe unavoidably, firm hard spot is formed
Impurity, makes subsequently to lead to ball disqualified upon inspection.
The underproof processing method of ball is led to more than in current overwhelming majority cooling wall manufacturer：With drain cleaner or
Stone dead wire is dredged, but the method can only be cleared up less firm impurity, and firmly impurity cannot then be removed, still
Study a kind of steel ball siphunculus method, decontamination treatment is carried out to water pipe, be prevented effectively from scrapping for casting.
The content of the invention
Instant invention overcomes the deficiency that prior art is present, there is provided the side of impurity in a kind of blast furnace cooling stave removal pipe
Method, simple to operate, low cost is time saving and energy saving, is prevented effectively from scrapping for casting.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：It is miscellaneous in a kind of blast furnace cooling stave removal pipe
The method of matter, operates as follows：
The first step：Steel ball is positioned in the water pipe of blocking from one end of water pipe, until the mouth of pipe is gradually overflowed by steel ball；
Second step：The steel ball of the mouth of pipe is impacted with hand hammer, makes the steel ball at blocking that the effect of thrust is produced to impurity thing；
3rd step：Keep impact, until making impurity thing come off；
4th step：Steel ball is ejected successively from other end stone dead wire；
5th step：After completing the 4th step, then do logical ball experiment and the water pressure test, it is ensured that casting is qualified.
The steel ball is using the steel ball in discarded bearing.
A diameter of standard of the steel ball purchases the 76% of bore.
The present invention has an advantageous effect in that compared with prior art：Can effectively be removed in pipe firmly using the present invention
Property impurity, without destruction pipe inner wall, it is ensured that logical ball inspection is qualified, it is to avoid casting is scrapped.
Specific embodiment
The method of impurity, operates as follows in a kind of blast furnace cooling stave removal pipe of the present invention：
The first step：Steel ball is positioned in the water pipe of blocking from one end of water pipe, until the mouth of pipe is gradually overflowed by steel ball；
Second step：The steel ball of the mouth of pipe is impacted with hand hammer, makes the steel ball at blocking that the effect of thrust is produced to impurity thing；
3rd step：Keep impact, until making impurity thing come off；
4th step：Steel ball is ejected successively from other end stone dead wire；
5th step：After completing the 4th step, then do logical ball experiment and the water pressure test, it is ensured that casting is qualified.
The steel ball is using the steel ball in discarded bearing.
A diameter of standard of the steel ball purchases the 76% of bore.
The present invention scraps in order to avoid casting, cylinder iron cold in accordance with national iron and steel industry professional standard YB/T4073 blast furnaces
But on the premise of wall requirement（Logical ball standard to being cast into cooling wall water pipe is：The 76%-2mm of bore is qualified）, for seamless
The specification of steel pipe, purchases steel ball in worn bearing, and 76% steel ball of bore is purchased by the standard of being better than, for removing impurity in pipe.
Operating method of the invention is：Steel ball is positioned in the water pipe of blocking from one end of water pipe, when a steel
Pearl is fallen into when in pipe, and first can be blocked by firm impurity thing, and the mouth of pipe is gradually overflowed by steel ball, now impacts steel with hand hammer
Pearl, makes first steel ball that the effect of thrust is produced to impurity thing, constantly in impact, impurity thing is come off, and is then used from the other end
Stone dead wire successively ejects steel ball, logical ball experiment and the water pressure test is finally done again, it is ensured that casting is qualified.
The present invention is low to material requirements, simple to operate, and smooth steel ball to seamless inside pipe wall without destruction, be a kind of being worth
The method of popularization.
The present invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to above-described embodiment, at this
In the ken that field those of ordinary skill possesses, various changes can also be made on the premise of present inventive concept is not departed from
Change.
