Description

Technical Field

[0001] The utility model belongs to the technical field of metal sampling, and specifically relates to a device for collecting shavings of molten steel in steelmaking. Background Art

[0002] Pig iron for steelmaking is the main raw material for converter steelmaking. To simplify the steelmaking process, improve the quality of steel products, and reduce production costs, hot metal pretreatment is an important pretreatment process before steelmaking. Desulfurization of hot metal reduces the sulfur content in hot metal, which helps to improve the steelmaking efficiency and the quality of steel products. Accurate detection of sulfur elements in molten steel for steelmaking is of great significance for guiding the steelmaking process.

[0003] Most domestic steel plants use two methods, namely "GB / T 4336-2016 Spark discharge atomic emission spectrometric analysis for multi-element determination of carbon steel and medium and low alloy steel" and "GB / T 223.79-2007 Determination of multi-element contents of steel and iron - X-ray fluorescence spectrometric method", to detect the desulfurized hot metal. Among them, the sulfur element analysis range of "GB / T 4336-2016 Spark discharge atomic emission spectrometric analysis for multi-element determination of carbon steel and medium and low alloy steel" is 0.008 - 0.05%, and the sulfur element analysis range of "GB / T 223.79-2007 Determination of multi-element contents of steel and iron - X-ray fluorescence spectrometric method" is 0.0026 - 0.1%. When accurately detecting low-content sulfur elements using the two methods of GB / T 4336-2016 and GBT / 223.79-2007, there are problems of exceeding the analysis range and poor analysis accuracy.

[0004] To accurately detect the sulfur element in pig iron for steelmaking, only "GB / T 20123-2006 Determination of total carbon and sulfur contents in steel and iron - Infrared absorption method after combustion in high-frequency induction furnace" can be used. The sulfur element analysis range of this standard is 0.0005 - 0.33%, and the analysis range, repeatability, and reproducibility meet the production requirements. The standard sample of infrared carbon and sulfur pig iron is usually in the form of shavings. GB / T 20123-2006 requires that the particle size of the test sample should be consistent and not less than 0.4 mm, and the particle size of the test sample for analysis and calibration should be the same. Therefore, it is required to process pig iron into shavings of test samples with a particle size not less than 0.4 mm. Since pig iron is brittle and hard, it cannot be drilled by a traditional drill press, and it is impossible to obtain shavings samples and it is not convenient to collect them.
