Description

Technical Field

[0001] The utility model relates to a zinc liquid sampling die and belongs to the technical field of metallurgical cold rolling detection. Background Art

[0002] With the wide application of galvanized sheets in various fields such as construction, automobiles, and home appliances, galvanizing plants have gradually emerged, and market competition is becoming increasingly fierce. In order to maximize benefits, in addition to developing high-end and high-profit new products, efforts should be made to improve product quality and reduce production costs. As we all know, the zinc pot is an important link in galvanizing, and the composition of zinc liquid is the top priority of research. We know that good products come from continuous and stable production. Reasonable control of zinc liquid composition and no drastic fluctuations will not only make product quality stable, but also effectively reduce production costs and improve product yield, which is a significant indicator of cost reduction. Then, how to ensure the stability of zinc liquid composition has become one of the focuses of research. Among the zinc liquid components, the effective aluminum content is one of the key detection items. In addition to the online aluminum content detection device, sample delivery and detection are also necessary. If the zinc liquid composition can be accurately mastered, then there will be a reassurance for the stability of product quality. The traditional sampling mold is a small steel cup, which is directly cast. Not only can it not eliminate zinc slag defects, but there is no riser supplement, which makes the test data of several zinc samples very different, and the effective zinc liquid composition is difficult to master. To this end, it is necessary to develop a zinc liquid sampling mold to accurately grasp the zinc liquid composition data, improve product stability, achieve precise production guidance, improve product quality and reduce production costs. Utility Model Content

[0004] The technical solution of the utility model is: a zinc liquid sampling mold, including a mold body and a fixed sleeve, the mold body is composed of two symmetrically arranged metal structures, three truncated cone-shaped cup cavities with larger upper parts and smaller lower parts are arranged in the central part of the mold body, the central position is a pouring cup, and the two sides are sample cups, a runner is arranged between the bottom of the pouring cup and the bottom of the sample cups on both sides, the pouring cup, the sample cup and the runner are symmetrically arranged separately in the middle, and the fixed sleeve is a metal hoop, and its inner shape matches the outer shape of the mold body.

[0005] In the zinc liquid sampling mold as described above, the cross section of the pouring channel is circular or quadrilateral. When the cross section of the pouring channel is quadrilateral, the corners are rounded, and the radius of the rounded corners is 3-5 mm.

[0006] The zinc liquid sampling die as described above, the upper opening radius of the sample cup is 35 - 45 mm, the lower opening radius is 15 - 25 mm, and the height is 40 - 60 mm.

[0007] The zinc liquid sampling die as described above, the runner is conical, and the connection part with the sample cup is the narrow - mouth end.

[0008] The zinc liquid sampling die as described above, the bottom corners of the sample cup are rounded, and the radius of the rounded corner is 5 - 8 mm.

[0009] The beneficial effects of the present utility model are as follows: The device of the present utility model has a simple structure and is convenient to operate. The zinc liquid is fully mixed through the runner, and the zinc liquid forms from bottom to top in the sample cup, ensuring the uniformity of the bottom. At the same time, the riser replenishes to reduce defects. The zinc slag components will stay in the runner, ensuring the qualification of the sampled product, accurate measurement data, and being conducive to guiding the production of high - quality products.

[0014] The following further illustrates the present utility model through examples in conjunction with the drawings.

[0015] As shown in the attached drawings, a zinc liquid sampling die includes a die body 1 and a fixing sleeve 3. The die body 1 is composed of two symmetrically arranged metal structures. At the central part of the die body 1, there are three frustum-shaped cup cavities with a larger upper part and a smaller lower part. The one at the central position is the sprue cup 2, and the two on both sides are the sample cups 4. A runner 5 is arranged between the bottom of the sprue cup 2 and the bottoms of the two sample cups 4 on both sides. The sprue cup 2, the sample cups 4, and the runner 5 are symmetrically arranged with a middle separation. The fixing sleeve 3 is a metal ferrule, and the inner shape thereof matches the outer shape of the die body 1. The cross-section of the runner 5 is circular or quadrilateral. When the cross-section of the runner 5 is quadrilateral, the corners are rounded, and the radius of the rounded corner is 5 mm. The bottom corners of the sample cup 4 are rounded, and the radius of the rounded corner is 8 mm. The rounded corner design is beneficial for the separation of the solidified zinc block from the die without corner adhesion. The upper mouth radius of the sample cup 4 is 40 mm, the lower mouth radius is 20 mm, and the height is 50 mm. The runner 5 is conical, and the connection with the sample cup 4 is the narrow end, which is beneficial for retaining the zinc slag in the runner and also for peeling the runner from the zinc sample after solidification.

[0016] During use, place the die flat, put the fixing sleeve 3 on the outside of the die body 1 to fix the die body 1. Pour the zinc liquid from the sprue cup 2. The zinc liquid enters the sample cup 4 through the runner 5 and fills the sample cup 4 from the bottom. After the zinc liquid solidifies, remove the fixing sleeve 3, separate the die body 1, take out and separate the sample and the solidified runner, and the production of the zinc liquid sample is completed.

[0017] The utility model device has a simple structure and is easy to operate. The zinc liquid is fully mixed through the runner. The zinc liquid forms from the bottom up in the sample cup, ensuring the uniformity of the bottom. At the same time, the riser replenishes to reduce defects. The zinc slag component will stay in the runner, ensuring the qualification of the sampled product, accurate measurement data, and being beneficial for guiding the production of high-quality products.
