Problems solved by technology

Usually, composite silicon carbide contains free carbon, silicon carbide, aluminum oxide, calcium, titanium, phosphorus and other material elements. Conventional detection techniques generally measure the content of each element one by one, and the measurement methods used are independent of each other. At present, there is no mature detection method for the determination of the composite silicon carbide, and there is no national standard, and the existing silicon carbide, that is, the national standard for the inspection of SiC>95%, is not fully applicable to the determination of the composite silicon carbide for metallurgy

Abstract

The invention relates to a method for measuring the substance content of composite silicon carbide. The composite silicon carbide contains the following substance elements: free carbon, silicon carbide, aluminum oxide, calcium, titanium, phosphorus and the like. The method for measuring the substance content of the composite silicon carbide comprises the following steps of measuring the content of the free carbon by adopting a burning method; measuring the content of the silicon carbide by measuring the residues of the free carbon; measuring the content of subsequent substances by measuring the product of the silicon carbide. The method for measuring the substance content of the composite silicon carbide, which is disclosed by the invention, can be used for measuring the other substances by measuring the substances, such as the free carbon and sample residues, and filter liquor which are remained from the silicon carbide, so that the resampling is avoided, and further the measurement cost is reduced, the measurement efficiency is improved.

Description

technical field [0001] The invention relates to a method for measuring chemical substances, in particular to a method for measuring the content of substances in composite silicon carbide. Background technique [0002] Composite silicon carbide is widely used as a new type of strong composite deoxidizer in the steelmaking process. It has the characteristics of rapid deoxidation, strong reaction and strong deoxidation ability. Composite silicon carbide can not only achieve the effect of strengthening deoxidation in the steelmaking process, but also increase silicon and carbon, and replace ferrosilicon, carbon powder and some ferrosilicon and aluminum; in order to determine the specific effect of composite silicon carbide on the steelmaking process, it is necessary to The content of various substances in the composite silicon carbide is determined. Usually, composite silicon carbide contains free carbon, silicon carbide, aluminum oxide, calcium, titanium, phosphorus and other ...
