Background
In the metal smelting process, sampling, inspection and analysis are indispensable links for ensuring the smelting quality, and the addition proportion of alloy elements and base metal can be adjusted according to actual conditions through analysis of molten metal components to ensure that the chemical components of the molten metal are in a controllable state. The traditional sampling is mostly spooned in a molten pool, poured into a mold with a certain shape, and then the position without casting defects is selected for chemical composition analysis. The sampling mode wastes metal solution, impurities such as slag, covering agents and the like easily enter the sample in the sampling process, and the accuracy of a component detection result is seriously interfered. In addition, the traditional sampling mode is limited by the sampling depth, only the chemical components of the shallow metal in the furnace can be measured, and the sample representativeness is poor.
The invention is mainly applied to the detection of carbon equivalent in molten steel in a measuring probe for sampling in molten metal in Chinese patent with patent publication No. CN103630423A, but the structure is complex and the use cost is high. CN108225845A presents a sampler for hot metal, providing a DA type sample for OES analysis that can be used to sample hot metal and form a crack-free solidified hot metal sample, but the structure is complex and the sampled sample volume is small. CN207439730U is used for the sampling tool of molten metal liquid sample, and this sampling tool includes sample cup and bracing piece, and the sample cup is made by non-metallic refractory material spare in the industry, has reduced the pollution of sample cup to molten metal liquid, has guaranteed the accuracy of the kind and the content of metallic element in the sample, but can only survey the chemical composition of stove top layer metal, can not get the metal sample of position darker.

an end cover 5 is arranged on the sampling cup 1, the end cover 5 is sleeved on the handheld rod 6 through the shaft hole 3, and the upper end of the end cover 5 is further connected with a push-pull rod 7.
The push-pull rod 7 is arranged on the end cover 5 through the threaded hole 4, and the end cover 5 can move up and down and rotate left and right under the action of the push-pull rod 7.
The sampling cup 1 is of an inverted cone structure, and the cup wall and the cup bottom are arranged at a certain angle, so that the sampling cup can be conveniently demoulded after sampling.
The bottom of the end cover 5 is of a concave structure, one side of the concave surface of the end cover completely covers the top of the sampling cup 1 and extends downwards to prevent slag and covering agent from entering the sampling cup.
The surface of the handheld rod 6 is provided with scales for displaying the sampling depth.
The shaft hole 3 is in clearance fit with the handheld rod 6.
In this embodiment, the sampling cup 1 is hollow, and the inner surface of the cup wall can be coated with a coating, so as to facilitate demoulding after sampling.
In this embodiment, all the parts are made of materials that are not reactive with the metal solution and have a shape and properties that remain stable during sampling.
In this embodiment, the utility model relates to a molten metal sampling device's working method as follows:
during sampling, the end cover 5 is pushed towards one side of the sampling cup 1 through the push-pull rod 7, the end cover 5 is ensured to be in close contact with the top end of the sampling cup 1 (the end cover is closed), slag, a covering agent and the like on the surface layer of molten metal are taken off, and the sampling device is vertically and slowly placed into the metal liquid to be sampled;
when the sampler sinks to a specified depth (the scales on the handheld rod 6 can be referred), the push-pull rod is lifted upwards, so that the end cover 5 is ensured to be removed from the top end of the sampling cup 1 (the end cover is opened), and molten metal enters the sampling cup 1;
after the sampling cup 1 is filled with molten metal, the end cover 5 is closed, the sampling device is slowly taken out of the molten metal through the handheld rod 6 in the state, after the metal is solidified, the sampling cup 1 is inverted, the cast ingot is demoulded and taken out by utilizing the gravity action of the metal, and the whole sampling process is finished.
