Embodiment 1

[0042] A zinc-calcium master alloy for hot-dipping is prepared according to the following method:

[0043] A. 72.7 parts of 99.95 zinc ingots and 27.3 parts of metal calcium (purity 99%wt) are fed and melted at the same time, and the argon protection is turned on. When the melting temperature reaches 650 ° C, increase the blowing and stirring, and the gas used for blowing and stirring is argon. The pressure is 0.02MPa;

[0044] B. After blowing and stirring for 8 minutes, cool down naturally to 560°C, remove the slag, pour into the mold after the slag removal, and solidify to obtain the zinc-calcium master alloy for hot dipping. The temperature of the mold before pouring is 200°C.

Abstract

The invention discloses a detection of calcium, iron, aluminum, magnesium and manganese content in zinc-calcium alloy. The method comprises the following steps: A, heating and dissolving the zinc-calcium alloy in a solvent, and diluting to obtain analysis solution, wherein the mass concentration of the analysis solution is 0.04+0.01%; B, selecting analysis lines of calcium, iron, aluminum, magnesium and manganese; C, preparing the standard solutions with various to-be-detected element concentrations from low to high according to the concentrations of various to-be-detected elements in the zinc-calcium alloy, importing the standard solutions into an ICP emission spectrometer, measuring the emission light intensities corresponding to different concentrations of various to-be-detected elements by using the analysis lines corresponding to various elements, and drawing a standard curve; and D, importing the analysis solution obtained in the step A into the ICP emission spectrometer to measure the emission light intensity corresponding to various to-be-detected elements, and determining the contents of various to-be-detected elements according to the standard curve obtained in the step B. The contents of the required elements can be simultaneously detected by only using one solution, the test solution preparation process is simple, the detection process is simple and fast, the detection result is good in stability and high in accuracy.

Description

technical field [0001] The invention relates to a method for detecting the content of calcium, iron, aluminum, magnesium and manganese in a zinc-calcium alloy, belonging to the field of detection of zinc-calcium alloy elements. Background technique [0002] In the field of detection of element content, the detection of calcium, iron, aluminum, magnesium, and manganese content in zinc-calcium alloys often uses classical chemical analysis methods and atomic absorption spectrometry. Each time a sample is dissolved, only one element can be determined, and a variety of chemical reagents must be added from the sample dissolution to the final analysis, and a series of chemical reactions must be performed, which will inevitably lead to a cumbersome operation process, and each step may introduce errors. The result is slow analysis and not necessarily high accuracy. [0003] The classic detection methods currently used have the following disadvantages: [0004] 1. The analysis of ea...
