Metal liquid integrative performance on-line intelligent checking system

Abstract

The invention relates to an on-line detection system for molten metal integration property, which includes a signal collection device for generating electric signal correlated with molten metal temperature change, a data processing main frame, a thermoemf combination measuring interface device for carrying amplification and analog/digital conversion of the electric signal, which is convenient for processing digital signal by the data processing main frame, and a data output device including a data remote transmission device, a storage device, a display device and a printing device. The detection system is adapted for eighteen kinds of designation molten iron and nineteen kinds of key parameter fast detection prescribed by national standard and international standard, and has high detection accuracy and good stability.

Description

Technical field [0001] The invention relates to an online intelligent detection system for the comprehensive performance of molten metal. The system adopts thermal analysis combined technology, and can quickly detect various physical and chemical parameters of molten metal in front of the furnace, so as to adjust the composition and process of molten metal before casting. To control the quality of castings. Background technique [0002] The foundry industry is the foundation of the machinery manufacturing industry. In order to improve the quality of castings, the detection of the comprehensive performance of castings is a key process. The test of comprehensive performance should include not only the test of chemical components such as carbon content and silicon content, but also the test of physical parameters such as strength, hardness, elongation, spheroidization rate and carbide. The traditional casting inspection is to analyze (section) the sample or casting after the c...

Problems solved by technology

[0003] The existing on-line detection system for the comprehensive performance of molten metal can not really realize the comprehensive performance detection, such as the NSP-510 molten iron composition tester in front of the furnace of Japan's Sabron Detection Instrument Company, the PQ-DIT detection system of Sweden's Novacast Company, Germany's Detal - CII detection system, etc., although the detection speed is much faster than offline detection, but the identification and detection range is small, and the parameters that can be tested are few, and it cannot detect gray iron, ductile iron, marsh iron and high carbon molten iron at the same time , and the anti-interference ability, detection stability, reproducibility and detection accuracy are difficult to meet higher requirements
