Description
Technical field
The utility model belongs to steel-making support equipment field, is specifically related to a kind of continuous casting steel sampler.
Background technology
Need sampling in ladle beam, Metal in Tundish in steel-making continuous casting production run and molten steel composition is analyzed, now just need to use molten steel sampler, generally all adopt cup type three kinds of bucket-type, sonde-type and sample, the sample that bucket-type and sonde-type take out is respectively flat and round table-like or cylindric, and the specimen shape that sample cup for liquid takes out is determined by the shape of sample cup for liquid.Although flat sample can directly be analyzed after grinding by effects on surface, because surface is as-cast structure, higher to the requirement of grinding, workload is large, has a strong impact on work efficiency; Cylinder shaped test piece demoulding difficulty, sample in sampling process are easily with burr after taking out, and bring difficulty to sample processing, the utilization factor of sample mold is low.Bucket-type sampling mode solidifies to accelerate it after taking-up sample, generally put it in water and cool, to shorten the time being sampled to analysis result, boost productivity, but the sample shrinkage cavity of taking out is serious, organizes not fine and close, the utilization factor of sample is low, analysis result accuracy rate is low, even causes and cannot analyze, affect production efficiency.Although the cup type sampling mode of current sample can take out sample preferably, due to the restriction of its structure, the sample causing it to take out still there will be the phenomenon of shrinkage cavity, causes analysis result inaccurate, causes and cannot analyze, affect production efficiency time serious.
Utility model content
The purpose of this utility model is to provide a kind of continuous casting steel sampler, and take out rear shrinkage cavity phenomenon seriously to solve molten steel sample in prior art, organize not fine and close, sample analysis result accuracy rate is low, causes sample to analyze, the problem that production efficiency is low time serious.
For achieving the above object, the technical solution of the utility model is: a kind of continuous casting steel sampler, comprise sampling body 1 and Sampled Hand Grip 2, Sampled Hand Grip 2 is located at the side of sampling body 1, and be fixedly connected with sampling body 1, be provided with at least two upper taper holes 3 and lower cone hole 4 in sampling body 1, the bottom of lower cone hole 4 is provided with the sample plug 5 suitable with lower cone hole 4, and sample plug 5 is flexibly connected with lower cone hole 4.
Preferably, the minimum diameter of upper taper hole 3 is greater than the maximum inner diameter of lower cone hole 4.
Preferably, the maximum outside diameter of sample plug 5 is greater than the minimum diameter of lower cone hole 4.
The utility model has the advantage of: the utility model structure is simple, easy to use, sample take-off speed is fast, in use procedure, staff is only needed to hold Sampled Hand Grip, sampling body is stretched in molten steel, cooling is taken out after filling with molten steel in taper hole, sample plug is utilized to be taken out from taper hole by sample, the minimum diameter of upper taper hole is greater than the maximum inner diameter of lower cone hole, the molten steel heat-conduction coefficient at upper taper hole place is less than the molten steel at lower cone hole place, the molten steel solidification speed at taper hole place is reduced, accelerate the solidification shrinkage of the molten steel at lower cone hole place, decrease the internal shrinkage of sample, improve the molten steel probability that gas floating is discharged in taper hole simultaneously, decrease the bubble of sample inside, reduce the generation of sample shrinkage cavity phenomenon, not only increase sample mass, and improve the take-off speed of sample, effectively improve the accuracy rate of sample analysis, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional structure schematic diagram of the utility model sampling body.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of continuous casting steel sampler as depicted in figs. 1 and 2, comprise sampling body 1 and Sampled Hand Grip 2, Sampled Hand Grip 2 is located at the side of sampling body 1, and be fixedly connected with sampling body 1, at least two upper taper holes 3 and lower cone hole 4 is provided with in sampling body 1, the bottom of lower cone hole 4 is provided with the sample plug 5 suitable with lower cone hole 4, and sample plug 5 is flexibly connected with lower cone hole 4.
In order to reduce the generation of sample shrinkage cavity phenomenon, the minimum diameter arranging taper hole 3 is greater than the maximum inner diameter of lower cone hole 4, the molten steel heat-conduction coefficient at taper hole 3 place is made to be less than the molten steel at lower cone hole 4 place, the molten steel solidification speed at taper hole 3 place is reduced, supplement the solidification shrinkage of the molten steel at lower cone hole 4 place, decrease the internal shrinkage of sample, improve the molten steel probability that gas floating is discharged in taper hole simultaneously, decrease the bubble of sample inside.
Sample the tightness of body during in order to ensure to materials, ensure that molten steel can not flow out lower cone hole 4, the maximum outside diameter arranging sample plug 5 is greater than the minimum diameter of lower cone hole 4.
The course of work of the present utility model is as follows: first, and sample plug 5 is inserted lower cone hole 4, and ensures that sample plug 5 stretches out the bottom of lower cone hole 4, make its coordinate firm after, use separant smear sampling body 1 inside and outside after drying for standby; Secondly, staff holds Sampled Hand Grip 2, is sampled the appropriate location that sampling body 1 stretches into Metal in Tundish, after waiting for that molten steel is full of sampling body 1, takes out sampling body 1; Again, after waiting for that molten steel solidifies completely, sample is taken out by knocking outstanding sample plug 5; Finally, the molten steel sample of taking-up is sent to laboratory in time and carries out the analytical works such as constituent analysis.
Sampling body 1, in molten steel sample sampling process, also can be accessed ladle beam, be poured into by molten steel in sampling body 1, carry out molten steel beam sampling operation by the utility model.
Above-described is only preferred embodiments of the present utility model; the technical solution of the utility model is not limited thereto; should be understood that to those skilled in the art; under technology enlightenment provided by the utility model; as the common practise of this area; other equivalent modifications and improvement can also be made, also should be considered as protection domain of the present utility model.
