Description

Technical Field

[0001] This utility model relates to the field of lightweight scrap steel sample preparation technology, specifically a lightweight scrap steel sample preparation device. Background Technology

[0002] The main types of aluminum-based ferroalloys used in steelmaking include ferroaluminum, ferromanganese, ferrosilicon, and other alloys containing a certain amount of alkaline earth metals. These alloys are high-quality deoxidizers and alloying agents used in steelmaking and are widely used to replace pure aluminum for deoxidation and alloying of molten steel. The production of these alloys depends on the specific requirements of each product, and different raw materials are selected, such as remelted aluminum ingots, scrap steel, metallic manganese, medium-carbon ferromanganese, alkaline earth metals calcium, strontium, and barium, as well as industrial silicon and ferrosilicon. Aluminum ingots and scrap steel account for a relatively large proportion of the raw material usage. To ensure that the quality of raw materials meets the standard requirements, composition monitoring is a crucial aspect of quality management.

[0003] Scrap steel alone requires inspection of over 10,000 tons annually. To ensure product quality, production efficiency, and low costs, the scrap steel is generally thin and light, with a thickness of no more than 4mm (mostly less than 2mm). These scrap steels vary in thickness, size, shape, and hardness, making sample preparation extremely difficult. Previously, large iron shears were used to cut randomly selected scrap steel into small pieces, but this was extremely difficult, time-consuming, and labor-intensive. Furthermore, it was impossible to cut relatively thick samples into suitable pieces, resulting in poor sample representativeness. Sometimes, the lack of representativeness in sampling led to quality disputes. Therefore, we proposed a thin and light scrap steel sampling device to solve these problems. Utility Model Content
