Description

Technical Field

[0001] The utility model relates to the technical field of molten iron sampling and analysis instruments, and particularly relates to a multifunctional molten iron sampler. Background Technique

[0002] In the production process of metal castings, accurately detecting the main chemical components of molten iron is a key step to ensure product quality. At present, the commonly used instruments for in-furnace analysis are direct-reading spectrometers and infrared carbon-sulfur analyzers. A direct-reading spectrometer can detect multiple elements, but the detection results of non-metallic elements such as carbon and sulfur have large errors. Therefore, an infrared carbon-sulfur analyzer needs to be additionally used to detect carbon and sulfur elements. However, existing samplers usually can only meet the sampling requirements of a single instrument, with cumbersome operations and low efficiency. Moreover, existing samplers cannot be disassembled, and after the molten iron is poured, it is not easy to remove the pouring mold, reducing the applicability of the sampler.
