The invention discloses a method for measuring the yield of broken scrap steel metal materials, and relates to the technical field of metal recovery. The method for measuring the yield of the broken scrap steel metal material comprises the following specific operations: S1, preparing related equipment, namely preparing a 200kg vacuum induction furnace for melting broken scrap steel, an ingot mold for pouring steel ingots, a platform scale for weighing the scrap steel with the precision of 0.05 kg, an electronic scale for weighing alloys and samples with the precision of 0.01 g, and a spectrum analyzer for component analysis. According to the method for measuring the yield of the crushed scrap steel metal material, the yield of the metal material is measured by adopting a mode of adding electrolytic nickel and taking [Ni] as a tracer agent and matching with an original weighing method, so that the measurement accuracy is effectively improved, and meanwhile, the influence degree of human errors on a result is reduced; the accuracy of final numerical values is improved while the operation difficulty is reduced, and large-scale production is facilitated.
Description
technical field [0001] The invention relates to the technical field of metal recovery, in particular to a method for measuring the yield of crushed scrap metal material. Background technique [0002] In the process of metal recovery, it is necessary to calculate the yield of metal materials. The metal yield refers to the production of steel billets per unit time and the steel materials and other alloy materials consumed in the production of this batch of steel billets during the steelmaking production process. The ratio of the sum of . [0003] In the prior art, only a simple weighing method is used to roughly calculate the yield. This method is prone to large errors due to human error, which increases the difficulty of operation and reduces the accuracy of the final value. , is not conducive to large-scale production. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] Aiming at the deficiencies of the prior art, the present invention provides a me...
