Background
In the steel metallurgical process, in the steel making, continuous casting and other processes, it is necessary to extract a metal solution sample from a metal solution and analyze parameters such as chemical components of the sample. When a metal solution sample is extracted, a sampling probe is usually inserted into a sampling gun, the sampling gun and the sampling probe are inserted into a steel ladle filled with liquid molten metal through a transmission mechanism, the molten metal enters a steel mould of the sample body through a sampling port of the sampling probe and is held, and after the steel ladle is pulled out of the sampling probe, the molten metal is solidified and forms a solid. As shown in fig. 1, a typical sampling probe 1 for this type of application consists essentially of two long cylindrical tubes of paper: a clamping section 2 and a sampling section 3. Wherein, a refractory material draft tube 17 is arranged on the sampling section 3 contacted with the metal solution, the refractory material draft tube 17 is provided with a sampling port on the surface of the sampling section 3, and the whole body of the refractory material draft tube 17 is composed of refractory material or ceramic body. Wherein, probe sample section 3 contains steel honeycomb duct 16, refractory material honeycomb duct 17, steel mould 37 that are used for forming and hold metal sample body 18 and wraps up the obround fiber container and the ceramic body 19 etc. of the tip of above-mentioned a plurality of parts, and sampling probe afterbody clamping section 2 has the obround centre gripping fiber container that does benefit to the mechanism and snatchs.
In order to analyze the metal solution in the ladle in real time, a metal sample body formed by solidification after sampling must be separated from a sampling section in a sampling probe in time.
At present, a method of manually holding a clamping section paper tube of a sampling probe by hand and knocking the sampling section paper tube so as to take out a sample body is mostly adopted. Because of the manual operation, the sampling probe body is not reliable in terms of safety and efficiency in consideration of the fact that the sampling probe body is even in an open fire state during knocking. In order to more efficiently grasp the state of molten metal, the time for sampling and sample feeding is shortened as much as possible, and the related process steps are performed as soon as possible.
In the conventional patent application, in the device for automatically exposing the sample body as described in patent document "device for automatically exposing the sample body" CN 203545142U, since the internal structure of the sampling probe is such that the housing having the sample body is surrounded by the filling material and the paper tube, the former processing manner of the sampling probe in the patent, that is, the method of extruding the filling material and the sample body having the housing from the paper tube by the punch, is not applicable to all types of sampling probes. For example, in the sampling probe disclosed in the patent application, the shell of the sample body is directly wrapped by the steel die and the paper long round tube, and the wrapping structure has a stepped structure, so that the shell with the sample body cannot be separated from the steel die and the paper long round tube by a punch extrusion method.
Further, in the apparatus for automatically exposing sample bodies as described in "apparatus for automatically exposing sample bodies" of patent document CN 203545142U, since the housing having the sample bodies is dropped into the housing removing apparatus and then separated by the centrifugal means, that is, the housing having the sample bodies is fixed by the clip, the centrifugal means is expected to push the housing toward the collision body by the impulse generated by the collision by striking the housing and then to knock the housing, and the sample bodies can pass through the housing removing apparatus alone, there is a problem that the centrifugal means can be rotated at a high speed and after a plurality of times of strong strikes, the sample bodies can be separated from the housing, the apparatus is complicated, and it is not guaranteed that the sample bodies can be completely separated from the housing.
