Abstract

The utility model relates to a molten steel sampler for electrolysis of a small sample, in particular to a molten steel sampler used in refining for steel making, belonging to the technical field of a special device in the metallurgical industry. In the technical scheme, the molten steel sampler comprises a sampler body, an inner cavity, an upper sealing cover, an inner coating and a base, wherein the wall of the sampler body is connected with the upper sealing cover and the base to form the inner cavity; and the inner coating is arranged on the inner side of the sampler body. In the improvement, the base is tapered. By adopting the molten steel sampler, the sampling success rate is high and wrapping of residues can be prevented effectively. Moreover, the molten steel sampler is simple and reliable, is convenient to operate, and is particularly suitable for sampling in refining during steel making.

Description

A kind of sample electrolysis molten steel sampler

Technical field

The utility model relates to a kind of sample electrolysis molten steel sampler, relates in particular to the molten steel sampler that the refining link is used in a kind of steelmaking process, belongs to metallurgy industry specialized equipment technical field.

Background technology

The sample electrolytic process is to detect a kind of effective ways of snotter, grades by The amount of inclusions, size, pattern, one-tenth after the sample electrolysis and manyly quantitatively comes analysis-by-synthesis to make steel link molten steel cleanliness factor state of a control with qualitative analysis.Generally carrying out the snotter electrolysis is can take a sample by mechanical processing tools on solid-state materials such as strand, but in the process of the different operation Control and Inclusion Removal of research steel-making link, relate to the liquid state sampling of link molten steel such as bag and crystallizer in converter, refining, the continuous casting, and the operation of liquid sampling is the difficult point of testing.Especially in steel-making refining link, after the refining finishing slag formed, ladle upper strata crust phenomenon was more common, because existing molten steel sampler is the bucket-type sampler, its bottom shape is a truncated cone-shaped.Utilize existing sampler sampling sample often to occur and wrap up in defectives such as slag, hollow, also can cause sampler to be difficult to break up skull when serious enters molten steel inside and causes the sampling failure, influence normal sample analysis, waste a large amount of manpower and materials, even cause whole sampling plan failure.

The utility model content

For solving the low problem of existing sampler sampling success ratio, reach from making steel the purpose that different operations successfully take out liquid molten steel, the utility model provides a kind of sample electrolysis molten steel sampler, this sampler has sampling success ratio height, can effectively prevent to wrap up in simultaneously the characteristics of slag, and is simple and reliable, easy to operate.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of sample electrolysis molten steel sampler comprises sampler main body, inner chamber, upper cover, coated inside and base in the composition, wherein, the body wall that constitutes the sampler main body is connected with upper cover and base, forms inner chamber; Coated inside is located at sampler main body inboard, and its improvements are that described base is taper.

Above-mentioned sample electrolysis molten steel sampler, described sampler main body are up big and down small round table-like, and body wall thickness from top to bottom diminishes gradually.

Above-mentioned sample electrolysis molten steel sampler, described inner chamber has back draught.

The beneficial effects of the utility model are that sampling success ratio height, while can effectively prevent to wrap up in slag, and be simple and reliable, easy to operate, the refining link that is suitable for especially making steel sampling use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model synoptic diagram

1. upper covers among the figure, 2. sampler main body, 3. coated inside, 4. inner chamber, 5. base.

Embodiment

Referring to Fig. 1, sampler main body 2 can be added by the round steel machine and forms, and forms the body shape of bottom taper, so that it has good break effect.Body wall is connected with upper cover 1 and base 5, forms inner chamber 4; The top of sampler main body 2 is provided with upper cover 1, and upper cover is made by flat cold-rolled sheet, links with main body by compacting.Molten steel upper strata slag entered sampler when upper cover 1 can prevent to take a sample, upper cover 1 fusing when sampler is goed deep into molten steel inside, and molten steel normally flows into sampler inside again.Be provided with coated inside 3 in sampler main body inboard, sampler inside scribbles the bath of glass coating and prevents that sample and the adhesion of sampler inwall be convenient to sample and take out, and forms good specimen surface quality simultaneously.Sampler main body 2 is up big and down small round table-like, and body wall thickness from top to bottom diminishes gradually.Adopt this design, when slowly entering in the molten steel process, sampler comparatively fast finishes preheating because the lower body wall thickness is less, very fast raising sampler bottom temp, prevent that molten steel from entering after the sampler condensation rapidly, also can create the strong condition of bits come-up and wrap up in slag to avoid sample even volume slag phenomenon occurs; And sampler base circular cone streamline shape profile prevents that the molten steel local eddy currents produces in the sampler insertion process, wraps up in slag to avoid sample; Inner chamber 4 has back draught and helps the sample taking-up.In the present embodiment, sampler main body 2 is connected with upper cover 1 and base 5, the back cut diameter of sampler main body 2 is that 80mm, lower port diameter are 50mm, the high 150mm of being, the back cut diameter of inner chamber 4 is that 40mm, end opening are diameter 30mm, the high 120mm of being, base 5 height are 40mm.
