The limiter is used to abut the middle-pack sample port to ensure the consistency of the insertion depth of the sampler, and the plug-in rod position is fixed through a threaded top rod. The limit ring at the lower end of the sliding rod is greater than the diameter of the sampling hole to achieve stability of the sampling position.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of iron and steel casting, in particular to a tundish sampler. Background Art
[0002] In the field of iron and steel casting, it is often necessary to sample and analyze the finished product of tundish molten steel to analyze the component content of the molten steel. Usually, when sampling, it is necessary to take multiple samples at the same depth. Controlling the consistency of the sampling position is very important. Slight carelessness in the component deviation will affect the component judgment of the entire furnace of steel.
[0003] Often when sampling, the operator directly inserts the insertion end of the glass tube sampler wrapped with a hard paper tube onto the sampling rod, and then inserts the sampler into the molten steel for sampling. Since multiple samplings need to be repeated, it is very difficult for the operator to control the consistency of the depth of the sampler inserted into the molten steel, resulting in inevitable deviation in the components of the taken finished samples. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a tundish sampler, which can effectively ensure the consistency of the sampling depth of tundish molten steel, and at the same time can adjust the sampling position according to needs, which is convenient and fast.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A tundish sampler, comprising,
[0007] Sampler;
[0008] Sampling rod, the sampling rod includes a hand rod and an insertion rod, and the hand rod and the insertion rod are fixedly connected through an arc section, and the free end of the insertion rod is inserted and fixed on the sampler;
[0009] Limiter, the limiter is fixedly connected to the insertion rod and is used to limit the position of the sampler inserted into the tundish.
[0010] A further improvement of the utility model is that the limiter includes a fixed tube, the fixed tube is fixedly connected to the insertion rod, a sliding rod is inserted and fixed in the fixed tube with adjustable position, and a threaded ejector rod is radially and threadedly fixed to the fixed tube for pressing against the sliding rod.
[0011] A further improvement of the utility model is that the lower end of the sliding rod is fixedly connected with a limit ring, and the bottom edge length of the limit ring is greater than the diameter of the sampling hole of the tundish to be sampled.
[0012] A further improvement of the utility model is that a hand ring is arranged at the free end of the hand rod.
[0013] A further improvement of the present utility model is that both the sampling rod and the position limiter are made of cast steel parts.
[0014] The beneficial effects of the present utility model are as follows:
[0015] By setting a position limiter on the sampling rod, the position limiter abuts against the sampling port of the tundish to ensure the consistency of the depth of the sampler inserted into the tundish, thereby ensuring the stability of the sampling composition.
[0016] By setting the position limiter as a fixed pipe, a plug-in rod and a threaded jack rod, the position of the plug-in rod is fixed by the threaded jack rod, thereby ensuring the stability of the installation position of the plug-in rod.
[0017] In the present utility model, a position limiting ring is fixed at the lower end of the sliding rod, and the length of the bottom edge of the position limiting ring is greater than the diameter of the sampling hole of the tundish, thereby realizing the stability of the sampling position.
[0018] By setting a hand ring in the present utility model, the holding of the sampling rod is made more stable. BRIEF DESCRIPTION OF THE DRAWINGS
[0019] Figure 1 is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The present utility model will be further clarified below with reference to the drawings and specific embodiments. Embodiment
[0021] Combined with Figure 1 As can be seen, a tundish sampler includes a sampler 10, a sampling rod 20, and a position limiter 30. By setting the sampling rod 20 as a hand rod 201 and a plug-in rod 202, the hand rod 201 and the plug-in rod 202 are fixedly connected by an arc section. Such a setting can keep the operator away from the tundish sampling hole and reduce heat radiation. The free end of the plug-in rod 202 is inserted and fixed into the sampler 10. In this way, it is convenient to insert the sampler 10 into the molten steel for sampling by holding the sampling rod 20. The sampler 10 is a glass sampling tube wrapped with a hard paper tube, which is prior art and will not be described in detail here;
[0022] In addition, the position limiter 30 is fixedly connected to the plug-in rod 202 and is used to limit the position of the sampler 10 inserted into the tundish to maintain sampling stability.
[0023] Further, the stopper 30 includes a fixed tube 301 which is fixedly connected to the insertion rod 202. A sliding rod 302 is inserted and fixed in the fixed tube 301 with adjustable position. Such a setting can make the sliding rod 302 parallel to the insertion rod 202 and the sampler 10, better restricting the insertion depth. A threaded ejector rod 303 is radially and threadedly fixed to the fixed tube 301 for pressing against the sliding rod 302.
[0024] Further, a limit ring 3021 is fixedly connected to the lower end of the sliding rod 302. The bottom edge length of the limit ring 3021 is greater than the diameter of the sampling hole of the tundish to be sampled. The limit ring can be set as a triangle, which can facilitate observing whether it is in place in contact with the tundish sampling port.
[0025] Meanwhile, in order to hold the hand rod 201 more stably, a hand ring 2011 is provided at the free end of the hand rod 201.
[0026] In order to reduce the influence of molten steel on the sampling device, both the sampling rod 20 and the stopper 30 are made of cast steel parts.
[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention.
