Abstract

The invention discloses a high-performance stokehole liquid iron management analysis system. The composition and the working process of the system are as follows: a thermal analysis sensor is installed on a liquid iron furnace body, and transmits a temperature analog signal to a signal amplifying and conditioning circuit; the temperature analog signal is converted into a digital signal through signal conditioning, and the digital signal is transmitted through a Bluetooth transmitting module to a Bluetooth receiving module; a data acquisition card reads the temperature digital signal received by the Bluetooth receiving module and transmits the temperature digital signal to a virtual instrument; a computer reads the temperature information in the virtual instrument, and predicts the amount of supplement and the content of carbon and silicon in the liquid iron furnace by a grey neural network algorithm, and the computer realizes data sharing and calculating by a cloud computing algorithm via an Internet network; and a mobile phone accesses the cloud computing algorithm and realizes remote calculation and display of the liquid iron management analysis system through a GPRS network. The system of the invention enables users to conveniently maintain, extend and upgrade the virtual instrument. A grey theory and a neural network are combined to improve the prediction accuracy.

Description

1. Technical field [0001] The technical field involved in this system is analysis and measurement control technology, and specifically relates to a management and analysis system for rapid detection of various parameters of molten iron in front of the furnace. 2. Background technology [0002] In recent years, with the continuous improvement of the strength performance requirements of mechanical parts, the development and application of some new cast iron materials have received extensive attention, among which the development speed of high-strength nodular cast iron and vermicular graphite cast iron is particularly rapid. The key technologies for the production of high-strength nodular cast iron and vermicular graphite cast iron are the spheroidizing and vermicularizing processes before the furnace, and the quality of molten iron is the most influential factor on these pre-furnace treatments. Therefore, how to realize the rapid detection of molten iron before the furnace ha...
