Problems solved by technology

One sample takes about 4 hours. For large-scale inspections in iron and steel plants, the inspection volume of raw dolomite rubble is about 20 batches per day. In the actual inspection operation, there are low efficiency, long time, many people and labor. The disadvantage of high intensity also seriously restricts and affects the rhythm of existing inspection tasks

Abstract

The invention discloses a raw dolomite high-temperature melting X fluorescence measurement method. The method comprises the following steps: grinding a to-be-measured sample; obtaining a to-be-measured sample test piece; preparing a calibration sample; calibrating the sample test piece; adding a release agent; heating the sample melting furnace; establishing a calibration curve; and determining the elements of the to-be-measured sample test piece. The analysis method can be used for analyzing the content of magnesium and silicon in the raw dolomite by using an X-ray fluorescence spectrum method, can be applied to determination of magnesium and silicon content elements in the raw dolomite, can realize rapid, comprehensive and rapid analysis of the raw dolomite, has a shorter test period which is superior to that of similar high-temperature melting X-ray fluorescence analysis, and achieves accurate and rapid inspection.

Description

technical field [0001] The invention relates to the technical field of raw dolomite testing, and more specifically relates to a method for measuring raw dolomite by high-temperature melting X-ray fluorescence. Background technique [0002] Raw dolomite is a newly purchased material in the iron and steel plant. Raw dolomite plays a role in slag removal, adjustment of slag composition, alkalinity, viscosity and reaction ability in the ironmaking and steelmaking smelting processes in the factory. The purpose is to refine the metal with the required composition and temperature through the reaction of slag and metal. [0003] In order to meet the needs of production inspection indicators, the inspection of raw dolomite in the laboratory refers to "GB / T 3286.1-2012" Limestone and Dolomite Chemical Analysis Methods Part I: Measurement of Calcium Oxide and Magnesium Oxide Content Complexometric Titration and Flame Atomic Absorption Spectrometry and "GB / T 3286.2-2012" Limestone and ...
