Abstract

The invention relates to an intelligent detector for molten iron with comprehensive performances such as elastic modulus elongation, tensile yield strength and the like. The detector comprises a signal acquisition device, a thermoelectric force joint metering interface device, a data processing host and data output equipment; the signal acquisition device is used for generating an electric signalrelated to the temperature change of the graphite-state molten iron; the thermoelectric force joint metering interface device is used for carrying out amplification and analog / digital conversion on the electric signal, so that the data processing host can process a digital signal; and the data output equipment comprises a data remote transmission device, a storage device, a display device and a printing device. The intelligent detector is suitable for rapid detection of 22 types of molten iron and 20 key parameters specified in national standards and international standards, and is high in detection precision and high in stability.

Description

technical field [0001] The invention relates to an intelligent detector for molten iron with comprehensive properties such as elastic modulus, elongation, tensile yield strength, etc. The instrument adopts big data, Internet + and thermal analysis combined technology, and can sample molten iron in front of the furnace and quickly measure it online Various high-end physical and chemical parameters of cast iron materials are produced, so as to ensure the quality of high-end castings by adjusting the composition and process of molten iron before casting. Background technique [0002] As the foundation of the equipment manufacturing industry, the foundry industry is constantly facing the pressure of upgrading and manufacturing high-end castings. In order to ensure the quality of high-end castings, the on-line detection of key parameters in the comprehensive performance of castings before the furnace is the most important. The detection of comprehensive performance needs to incl...

Problems solved by technology

[0008] Compared with other similar molten iron testing equipment, other existing equipment can not really realize comprehensive performance testing, such as the NSP-510 molten iron composition analyzer in front of the furnace from Japan's Sabransi Detection Instrument Co., Ltd., and the PQ-DIT detection system from Sweden's Novacast company. , Germany’s Detal-CII detection system, etc., although the detection speed is faster than offline detection, it lacks key core indicators such as elastic modulus E, yield strength σs, elongation A, low temperature impact toughness Ak, and cast iron grade; the detection range is narrow, The function is single; and it cannot detect gray iron, ductile iron, marsh iron, high carbon and other real molten irons at the same time; it cannot meet the requirements of high-end castings in terms of anti-interference ability, detection stability, reproducibility and detection accuracy.
