A high-efficiency detection method for particle steel

Abstract

The invention relates to a high-efficiency detection method for particle steel, which includes: sampling the particle steel three times, determining the quality difference coefficient Z according to the sample ratio, and then processing the sample to ensure the representativeness of the sample, sieving the sample, and classifying the sample. It is the rough material group, the sieve material group, and the sieve material group. At the same time, the above sample groups are measured to determine the particle steel irregularity coefficient G and estimate the estimated particle steel water yield Y0 according to the preset rules, and determine Estimate whether the water yield Y0 can be used as the final total water yield. If not, melt the particle steel, and accurately adjust the current and melting time of the high-frequency reaction furnace during the melting process to ensure the melting effect, so as to determine the particle steel Water yield.

Description

technical field [0001] The detection method in the field of the present invention is specifically a high-efficiency detection method for particle steel. Background technique [0002] Particle steel is a by-product of the steelmaking process, which is made of various oxides formed by the oxidation of silicon, manganese, phosphorus, sulfur and other impurities in pig iron during the smelting process and salts formed by the reaction of these oxides with solvents. Composition, steel slag contains a variety of useful components: 2% to 8% of metallic iron, 40% to 60% of calcium oxide, 3% to 10% of magnesium oxide, 1% to 8% of manganese oxide, so it can be used as raw materials for iron and steel metallurgy, particles The mineral composition of steel is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide. Steel slag is clinker, which is a remelting phase with a low melting temperature. When remelting, the liquid The phase ...

AI Technical Summary

Problems solved by technology

[0003] 1. In the traditional method, the samples in the particle steel detection process are distinguished, so the water yield of the particle steel obtained has errors;

[0004] 2. The traditional method does not provide a method for quickly estimating the water yield of particle steel;

[0005] 3. In the traditional method, the melting process of the particle steel is not adjusted during the melting process, resulting in errors in the final detection results
