Research And Design On Iron Grade Of Fine Iron Powder Tester

Fine iron powder the total iron(Fe) content (iron grade) is an important indicator to measure the quality of iron ore. In order to improve economic efficiency efficiency and enhance market competitivene, meet environmental requirements, the universal application of the modern into the furnace, "Concentrate approach", "Concentrate approach" is the core of iron ore into the furnace to improve utilization, reduce slag volume, thus into the blast furnace iron grade of Tie Jingfen the implementation of evaluation is necessary.This test instrument designed to iron grade of fine iron powder achievement test function, taking into account the practicality of this tester measurement system based on the MCU, using MSP430F135 and peripheral interface devices, using permeability changes in theory affect the inductance the sensor the output inductor signal conversion and measurement, indirectly Iron grade of fine powder grade values. In this paper, Iron grade of fine powder grade and test the mechanism related to the nature of research, based on the tester is given a viable development of the overall design of the program.Test hardware design to architecture MSP430F135 microcontroller as the core construct the micro-controllers, sensors, signal conditioning circuits, double-integrating A/D, LCD monitors, etc. as one of the Tie Jingfen iron taste tester hardware platform.Experimental results showed that the MSP430F135 as the core of the testing instrument, it can be real-time display the measured values of the iron taste, the value of a resolution of 0.001 of its taste, good stability, to achieve the desired design goals.
