Abstract
The utility model discloses an extracting type molten steel and iron melt sampler. The utility model is mainly characterized in that a long paper tube (11) connects with a short paper tube (12), a short sleeve tube (3) is arranged at the left end in the short paper tube (2), the right end of short sleeve tube (3) is provided with an oblate iron sample mould (5), the left end of the oblate iron sample mould (5) is provided with a through hole (4), an opening at the right end of the oblate sampling mould (5) connects with the left end of a high-temperature resistant quartz tube (7), and the left end of the high-temperature resistant quartz tube (7) is sheathed with a small protecting cap (8). The right end of the short paper tube (2) is sealed with refractory cement (6) and the right end of the refractory cement (6) is provided with a large protecting cap (9). The left end of the long paper tube (11) is provided with a paper block (10) and the left end of the short paper tube (2) is provided with a paper block (1). The utility model has the main application that the sampler breaks through slag layers to sample in a steel-smelting furnace or iron-smelting furnace.
Description
The utility model relates to a kind of liquid-steel molten-iron sampler, especially a kind of bucket lifting liquid-steel molten-iron sampler.
In the steel-making ironmaking processes, to liquid-steel molten-iron sample examination aspect, most steelworks iron-smelters all are the sampler sample examinations with steel spoon or other pattern at present.All there is certain shortcoming in these two kinds of methods.The one, to pass through slag blanket with the steel dipper sampling, this just brings the slag blanket impurity in the molten steel or in the molten iron into unavoidably, and this just makes, and the steel sample is inaccurate can not be chemically examined.Also, prolonged the duration of heat, burn operating personnel accident has easily taken place again secondary sample.The 2nd, with other type sampler, though can avoid various shortcoming with the steel dipper sampling, but below the porch of taking a sample in its insertion molten steel is in the molten steel stove, molten steel returns from the below and causes in the sampler steel original mold, when having got sample sampler released from molten steel, because molten steel temperature height, mobile big, sampling is all in seconds finished, at this moment there is the part molten steel from sampler, to flow, thereby caused the sampling surface quality bad, the discontented ghost phenomenon that occurs of sampling sometimes, the surface occurs after the sampling that has and subside, the steel sample of this phenomenon can not be chemically examined.Must get again once again, cause the sampling success ratio low, increase the cost of steel-making ironmaking.
The purpose of this utility model provides and a kind ofly can make liquid-steel molten-iron sampling break through slag blanket at furnace inner sampling, has avoided occurring when getting the liquid-steel molten-iron sample shortcoming that ghost is not full or the sampling rear surface subsides simultaneously again.
The utility model is achieved like this, long paper pipe connects short paper pipe, left end has short sleeve in the short paper pipe, the short sleeve right-hand member is equipped with flat garden sections original mold, flat garden sections original mold left end has through hole, and sections original mold right-end openings place, flat garden is connected with high temperature resistant quartz ampoule left end, and high temperature resistant quartz ampoule right-hand member is with little helmet, short paper pipe right-hand member envelope has fire cement, and the fire cement right-hand member is equipped with big helmet.It is stifled at paper tube and short paper pipe left end paper to be housed.
During use bucket lifting sampler long paper pipe right-hand member is inserted the iron pipe identical with the long paper pipe internal diameter, the operator inserts sampler in molten steel or the molten iron with iron pipe, and the degree of depth is to be as the criterion by slag blanket.At this moment the little helmet of the big helmet of molten steel or molten iron is melting takes out sampler because static pressure molten steel or molten iron flow into from quartz ampoule in the sections original mold of flat garden again from molten steel, breaks paper tube and gets tapping sample.
The utility model compared with prior art has following advantage:
1, reliable fully, data are accurate, sampling success ratio height, the shortcoming of having avoided sampling ghost and surface to subside.
2, simple to operate, cost is low, and is economical and practical, easily promotes.Concrete structure of the present utility model and embodiment are provided by the following drawings.
Fig. 1 is that the utility model general structure is cutd open and shown synoptic diagram.
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are described in further detail.
With reference to shown in Figure 1, long paper pipe (11) left end connects short paper pipe (2), short paper pipe (2) left end is equipped with small casing (3), short sleeve (3) right-hand member is connected with flat garden sections original mold (5), flat garden sections original mold (5) left end has through hole (4), high temperature resistant quartz ampoule (7) is equipped with at flat garden sections original mold (5) right-end openings place, high temperature resistant quartz ampoule (7) right-hand member is with little helmet (8), short paper pipe (2) right-hand member has high temperature resistant cement (6), high temperature resistant cement (6) is connected with big helmet (9), be connected with little paper stifled (10) at the long paper pipe left end, be connected with big paper stifled (1) at the short paper pipe left end.
When sampling, sampler long paper pipe right-hand member is inserted the iron pipe identical with its internal diameter, the operator inserts sampler in molten steel or the molten iron with iron pipe, make the big helmet of molten steel or molten iron is melting, little helmet flows into by high temperature resistant quartz ampoule and causes in the sections original mold of flat garden, again sampler is taken out from molten steel or molten iron, break short paper pipe and get tapping sample.
Claims (1)
1, a kind of bucket lifting liquid-steel molten-iron sampler, it comprises long paper pipe (11), short paper pipe (2), little paper blocks up (10), big paper stifled (1) is formed, it is characterized in that: be connected with flat garden sections original mold (5) at short sleeve (3) right-hand member, be connected with high temperature resistant quartz ampoule (7) at the right-end openings place of flat garden sections original mold (5), right-hand member at high temperature resistant quartz ampoule (7) is with little helmet (8), right-hand member envelope at short paper pipe (2) has fire cement (6), right-hand member at fire cement (6) is connected with big helmet (9), has through hole (4) at the left end of flat garden sections original mold (5).
