Description

A sampling device for copper magnesium production composition detects

Technical Field

The utility model belongs to the technical field of metallurgy, and particularly relates to a sampling device for detecting copper and magnesium production components.

Background

When the magnesium copper rod is produced by the upward drawing method, in order to prevent the copper liquid from being exposed in the air to absorb oxygen, a layer of covering agent is covered on the surface of the copper liquid so as to achieve the effects of oxygen isolation and heat preservation. Meanwhile, slagging is easy to generate in magnesium-copper production, and the slagging agent floats on the surface of copper liquid along with the covering agent. When magnesium component monitoring requires sampling, the covering layer is pulled off, and then a sampling device is stretched into copper liquid for sampling, so that the copper liquid in the furnace generally absorbs oxygen; meanwhile, if the covering agent is not completely pulled out or passes through the covering layer, the covering agent often enters the sampling cavity, so that pit-shaped or impurity-mixed problems are caused after the copper water sample is formed, and the sample cannot be normally repaired and the components of the sample can be detected.

At present, the current copper liquid sampling device is more in kind, wherein mainly gives priority to two main types: the first type is a steel sampling cup, which comprises a cover and an uncovering cover, wherein a common cup cover adopts a thin steel sheet or an aluminum sheet, a handle is welded on the outer side, the covered sampling cup can effectively block a covering agent and the like after entering copper liquid, the cover plate is thoroughly melted, so that the copper liquid enters the cup body for sampling, the defect that the copper liquid is polluted due to the melting of the metal cover plate is overcome, and the magnesium-copper component is inaccurate due to the rising of the local copper content even if a pure copper sheet is adopted. Meanwhile, the steel sampling cup is easy to carry iron into the molten copper, so that the product quality is influenced; the second type is tectorial membrane sand type sampler, though can effectively avoid metal liquid to be contaminated, nevertheless can local burning loss and produce a large amount of flue gases at the sampling process, cause the inside great fluctuation that appears of copper liquid to influence the casting quality of magnesium copper pole, and this type of sampling tool can not used repeatedly.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a sampling device for detecting copper and magnesium production components, which comprises an end cover, a cup body, a sheath and a handle, wherein the end cover is provided with a plurality of holes and is connected with the cup body through threads; the sheath is in threaded connection with the handle and then in threaded connection with the cup body, and the joint of the sheath and the cup body is sealed by refractory mortar.

Compared with the prior art, the utility model has the following advantages: the structure is simple, and the cost is low; the design is reasonable, the durability is good, and the installation is convenient; the oxygen absorption of copper water can be reduced in the production sampling process, the slag blocks and the covering agent are prevented from entering the cavity of the sampling device, the pure graphite cup body and the sheath can avoid the pollution of copper liquid in the furnace caused by sampling, the stability of local sampling components is ensured, the sampling success rate is greatly improved, and the accuracy of spectral analysis is also improved.

Detailed Description

The sampling device for detecting the copper and magnesium production components as shown in the figures 1 and 2 comprises an end cover 2, a cup body 3, a sheath 4 and a handle 5, wherein the end cover 2 is provided with a plurality of holes 1, and the end cover 2 is connected with the cup body 3 through threads; the sheath 4 is connected with the handle 5 by screw thread and then connected with the cup body 3 by screw thread, and the joint of the sheath 4 and the cup body 3 is sealed by refractory mortar.

Before sampling in magnesium-copper production, a handle 5 and a sheath 4 are installed, an end cover 2 is screwed down, refractory mortar is used for sealing and baking for 30min, a sampling device slowly penetrates through a covering layer during sampling, extends into a position with the copper liquid depth of about 200mm-300mm, then stands for 8s-10s, and is lifted vertically and slowly at the same position after the copper liquid is completely filled in a cavity of a cup body 3. After the copper liquid is taken out, the end cover 2 can be taken down by using refractory tongs when the copper liquid is not completely solidified, and finally, the solidified sample is poured out. In the process, the end cover 2 can effectively prevent the covering agent and the slag block from entering the cavity of the device, when the covering agent and the slag block enter the copper liquid, even if the covering agent or the slag block is adhered to the upper surface of the end cover 2, the covering agent or the slag block can be quickly separated and lifted under the pressure of the copper liquid, the hole 1 in the end cover 2 cannot be blocked, and the copper liquid can enter the cup cavity through the hole 1 in the end cover 2.

The above embodiments are preferred embodiments of the present invention, and those skilled in the art can make variations and modifications to the above embodiments, therefore, the present invention is not limited to the above embodiments, and any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
