Description

Technical Field

[0001] The utility model belongs to the technical field of metal surface processing, and particularly relates to a device for detecting the surface coating content of steel wires in large quantities. Background Art

[0002] In the metal processing industry, wire drawing is a common metal processing technology, mainly used for producing steel wires of various specifications. This process involves passing thick steel wires through a series of gradually smaller dies (usually made of cemented carbide or diamond). Under the action of tensile force, the diameter of the steel wire gradually decreases, while its length and strength increase.

[0003] During the metal wire drawing process, lubricants play key roles such as cooling, reducing friction, improving surface quality, promoting forming, and increasing efficiency. The amount of the coating of the lubricant on the surface of the steel wire is directly related to the quality of the steel wire drawing process and is also closely related to the quality of the final product. Therefore, the detection of the surface coating amount of the steel wire is crucial.

[0004] Currently, when detecting the surface coating content of steel wires, a corresponding dissolving solution is prepared and placed in a beaker. The cut and weighed steel wires are put into the prepared dissolving solution. The beaker is heated until the solution boils. After a period of time, all the steel wires are taken out, washed, dried, cooled, and weighed. Through calculation, the surface coating amount of the steel wire is obtained.

[0005] If there are many samples, the steel wires are respectively loaded into separate test tubes, and the dissolving solution is filled in the test tubes. All the test tubes are placed in a beaker filled with water. By heating the beaker, the test tubes are heated in a water bath until boiling. After a period of time, the steel wires are taken out respectively, washed, dried, cooled, and weighed. Through calculation, the surface coating amount of the steel wire is obtained.

[0006] However, the above methods have many drawbacks. For example, since the containers are usually made of glass, when detecting a large number of steel wires, the containers are prone to breakage, which is unsafe; when heating the solution, an electric furnace is used for heating, with low heating efficiency and long time; during the heating process, the solution will boil over and overflow, which will damage the electric furnace and the test tubes; when conducting large-scale detection, in order to distinguish samples and avoid confusion, the processes of boiling and dissolving and washing, drying, and cooling need to be carried out one by one, which takes a long time; there will be a phenomenon that the coating on the steel wires in the test tubes is not completely dissolved during the reaction with the dissolving solution, resulting in inaccurate detection results. Summary of the Invention

[0007] The purpose of the utility model is to overcome the defects of the existing equipment and provide a device for detecting the surface coating content of steel wires in large quantities.

[0008] The technical solution adopted by the utility model is: a device for detecting the surface coating content of steel wires in large quantities, including a 430 stainless steel container and a sample rack placed in the container;

[0023] The following further describes the present utility model with reference to the drawings.

[0024] As Figure 1 and Figure 2 shown, the utility model is a device for detecting the surface coating content of steel wires in large quantities, including a container 1 made of 430 stainless steel and a sample rack 2 placed inside the container 1. The container 1 is made of 430 stainless steel so that there is no risk of breakage, and at the same time, it can be heated by an induction cooker, facilitating the rapid boiling of the solution. The container 1 is a cube with an open top, and the sample rack 2 is put in and taken out through the opening at the top of the container 1. Handles 6 are provided on both side walls of the container 1, facilitating the tester to move the container. The container 1 has a relatively deep space, and the zeolite placed at the bottom makes the phenomena of solution bumping and overflowing almost non-existent.

[0025] The sample rack 2 is of a frame structure. A support frame 4 is longitudinally provided in the sample rack 2, and sample bins 3 are provided between adjacent support frames 4. The top of the sample bin 3 is open for placing steel wires. Handles 5 are provided on the support frames 4 at both ends, facilitating the tester to take out the sample rack 2 from the container 1. A large number of dense holes 8 are opened on the wall of the sample bin 3, ensuring the full flow of the dissolution liquid. A water control gap 7 is provided at the bottom of the sample bin 3, ensuring that when the sample rack 2 is taken out, the dissolution liquid in the sample bin 3 can all flow out quickly.

[0026] As Figure 3 shown, the usage mode of the utility model is as follows:

[0027] Step 1, prepare the dissolution liquid;

[0028] Step 2, cut the steel wire samples into several small sections each 7 - 10 cm long, weigh each sample and record it;

[0029] Step 3, sequentially put the weighed steel wire samples into the sample bins respectively;

[0030] Step 4, put the sample rack with samples into container A filled with the dissolution liquid, and place container A on the induction cooker to heat until the solution boils;

[0031] Step 5, after a period of time, stop heating, take out the sample rack, and sequentially put it into other containers B and C filled with cleaning agents, manually shake and clean it. After cleaning, take out the sample rack, and when there is no more liquid dripping, put the sample rack into the oven to dry. After drying, take out the sample rack, and after cooling, weigh and calculate each sample respectively.
