DETAILED DESCRIPTION

[0012] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, systems, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0013] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.

[0014] Scrap steel, the primary raw material for converter or electric furnace steelmaking, has a significant impact on production costs, technical and economic indicators of the smelting process, and production stability. Water yield, the most important indicator of scrap steel quality, significantly influences scrap settlement prices, solvent consumption during the smelting process, splash control, and steel material consumption.

[0015] There are many types of scrap steel used in steelmaking at present. For heavy scrap steel, medium scrap steel and other clean scrap steel that can be directly put into the furnace, the water yield of the scrap steel can be accurately judged by manual visual observation or automatic quality inspection system; while for industrial steel chips, light and thin materials, particle steel, industrial crushed materials, etc., in order to facilitate moving to charging, they are usually briquetted or packaged, which brings great difficulties to the inspection of the water yield of the scrap steel. The manual naked eye or automatic quality inspection can only judge the surface quality, but the internal quality cannot be directly judged. What's more, some scrap steel suppliers will artificially adulterate the core of the briquettes or packaged materials, causing great losses to the steel mills.

[0016] In response to the current problem in the industry that the quality inspection methods for medium-pressed blocks, packaged materials, and crushed materials are cumbersome and inaccurate, this patent intends to indirectly measure the water yield of scrap steel by testing the density of scrap steel.

[0017] Among common industrial raw materials and waste materials, the prices of elements with densities greater than Fe, such as Au, Ag, Ni, Mo, Nb, Gu, and Pb, as either single elements or in complexes, are generally higher than those of scrap steel. This means that steel is the most dense and inexpensive material commonly found in industry. Therefore, the density of adulterants within scrap steel is generally lower than that of steel. The water yield of scrap steel decreases as its density decreases, making it theoretically feasible to indirectly measure its water yield using its density.

[0018] Please refer to Figure 1 , Figure 1 A flow chart of a method for semi-quantitatively measuring the water yield of scrap steel provided in one embodiment of the present application can be executed by an electronic device. The method may include S101 to S103.

[0019] S101 : determining target scrap steel from the scrap steel to be measured based on scrap steel parameters of the scrap steel to be measured.

[0020] S102: Calculate the density of the target scrap steel according to the mass and volume of the target scrap steel.

[0021] S103 , calculating the water yield rate of the target scrap steel based on the predetermined impurity density and the density of the target scrap steel, and determining the water yield rate of the scrap steel to be measured according to the water yield rate of the target scrap steel.

[0022] In the embodiments of the present application, the scrap parameters to be measured include the scrap material type, that is, the mass of a single piece of scrap. If the mass of a single piece of scrap is large, the single piece of scrap can be directly selected as a sample to calculate the water yield, i.e., the target scrap, and thus determine the water yield of the scrap to be measured. If the mass of a single piece of scrap is small, multiple pieces of scrap can be selected as samples to calculate the water yield, i.e., the target scrap, and thus determine the water yield of the scrap to be measured.

[0023] Specifically, the execution process can be as follows: Take a whole piece or a certain amount of scrap steel to be measured, weigh it and record it as m 废钢 .

[0024] Place the weighed scrap steel into a container filled with water or other non-toxic, non-volatile liquid with a volume measurement scale. Soak for 1 to 10 minutes depending on the type of scrap steel. Use the Archimedes displacement method to measure the volume of the scrap steel type, which is recorded as V. 废钢 .

[0025] Calculate the density of scrap steel ρ scrap steel = m 废钢 / V 废钢 ; The water output rate of scrap steel is calculated through theoretical models, which can also be used as the water output rate of scrap steel to be measured.

[0026] The present embodiment determines the target scrap from the scrap to be measured based on its scrap parameters, utilizing sample calculation to reduce computational complexity. Subsequently, the density of the target scrap is calculated based on its mass and volume. Finally, the water yield of the target scrap is calculated based on the predetermined impurity density and the density of the target scrap. The water yield of the scrap to be measured is then determined based on the water yield of the target scrap. This method is fast and efficient, enabling quick measurement, making it suitable for industrial applications and improving the accuracy of water yield calculations.

[0027] In one embodiment of the present application, the scrap steel parameters include quality; Determining target scrap steel from the scrap steel to be measured based on scrap steel parameters of the scrap steel to be measured, including: If the material type of a single piece of scrap steel in the scrap steel to be measured is within the first mass range, the entire piece is taken as the target scrap steel; If the material type of a single piece of scrap steel in the scrap steel to be measured is within the second mass range, the scrap steel of the target weight is taken as the target scrap steel; The minimum value of the first mass range is greater than the maximum value of the second mass range.

[0028] The first mass range is 20kg~3000kg, and the second mass range is 0~20kg.

[0029] Specifically, scrap steel types include steel cutting cakes, light and thin material briquettes, crushed materials, and packaged materials, including but not limited to other scrap steel types whose internal quality is difficult to measure.

[0030] For example, for scrap steel materials with a single piece weight of 20kg to 3000kg, the whole piece is measured; for scrap steel materials with a single piece weight of less than 20kg, 50 to 1000kg is measured.

[0031] In one embodiment of the present application, the water yield of the target scrap steel is calculated based on the predetermined impurity density and the density of the target scrap steel, including: The water yield rate calculation formula is used to calculate the water yield rate of the target scrap steel. The water yield rate calculation formula is:

[0032] Among them, ρ 废钢 represents the density of target scrap steel, ρ 杂质 represents the impurity density, ρ 钢 represents the steel density, where ρ 钢 =7600kg / m 3 The range of impurity density is: 2000~3500kg / m³.

[0033] Specifically, the derivation process of the calculation formula for scrap steel water output rate is: first step: .

[0034] The second step is simplification: .

[0035] The third step is simplification: .

[0036] The fourth step is simplification: .

[0037] .

[0038] Among them, V 废钢 、V 钢 、V 杂质 Represent the volumes of scrap steel, steel and impurities respectively, ρ 废钢 , ρ 钢 , ρ 杂质 Represent the density of scrap steel, steel and impurities, m 废钢 、m 钢 、m 杂质 Represent the mass of scrap steel, steel and impurities respectively, V 废钢 =V 钢 +V 杂质 .

[0039] The present invention proposes a method for semi-quantitatively measuring the water yield of scrap steel based on density changes, which has many advantages. The measurement process is fast and efficient, and can be completed in a short time, which is very suitable for industrial application scenarios; it is simple and easy to operate, does not require complex equipment, and does not require pre-treatment of samples, which greatly reduces the difficulty of operation; the cost advantage is significant, and compared with traditional methods, the equipment cost and maintenance costs are greatly reduced; it achieves a moderate balance in accuracy, and on the basis of ensuring a certain accuracy, it can fully meet the actual needs of industrial production. With the characteristics of being fast, simple, low-cost and moderately accurate, this method provides a more practical and economical solution for the semi-quantitative measurement of the water yield of scrap steel, and can be effectively used for the rapid evaluation and monitoring of the water yield of scrap steel in industrial production processes.
