Analysis of chemical composition adjustment of aluminum alloy during smelting process before die casting

是一个要求严谨的过程,压铸的前提必须要熔炼铝合金,使其为熔融的金属液,而在熔炼过程中,由于各种原因都可能会使合金彩虹股份发生改变,这种改变可能使熔体的真是成分与配料计算值发生较大的偏差,因而须在炉料熔化后,取样进行快速分析,以便根据分析的结果确定是否需要调整成分。 Aluminum alloy die-casting is a rigorous process. The premise of die-casting must be to melt the aluminum alloy to make it a molten metal liquid. During the smelting process, alloy rainbow shares may be changed for various reasons. This change The actual composition of the melt may be greatly deviated from the calculated value of the ingredients. Therefore, after the charge is melted, a sample must be taken for rapid analysis in order to determine whether the composition needs to be adjusted based on the results of the analysis.

快速分析试样需要有代表性,天然气炉在两个炉门中心部位各取一组试样,电炉在 1/2熔体的中心部位取试样。 The rapid analysis of aluminum alloy die-casting samples needs to be representative. A natural gas furnace takes a group of samples at the center of two furnace doors, and an electric furnace takes samples at the center of 1/2 melt. The spoon should be preheated before sampling. For high-purity aluminum and aluminum alloy, in order to prevent the sample spoon from being contaminated, the stainless steel sample spoon should be used for sampling.

厂家快速分析结果和合金要求成分不相符时,就应调整成分,补料或者冲淡,如果是补料,则要通过计算保证补料准确。 When the rapid analysis results of the aluminum alloy die-casting manufacturer do not match the required composition of the alloy, the composition should be adjusted, replenished or diluted. If it is replenishment, the replenishment must be calculated to ensure accuracy.
