铁矿石氧化还原反应动力学实验系统的设计

The design of iron ore oxidation-reduction reaction kinetics experiment system

阐述了铁矿石氧化还原反应实验系统的设计原理、工艺流程、设计思路,包括硬件和软件方面的设计以及系统在实验中的应用情况等。系统可为实验过程物料反应提供等温、非等温的实验温度场和精确的气氛环境。实验结果表明:该系统可实现对200～1 600℃区间内的温度和升温速率的精确控制,控制精度为±1℃,对气体流量的控制精度为±0.01L/min,质量测量精度为±0.001g。

The principles of design, experiment process, including hardware and software design, application of ideas of system design, the system in actual experiments, and so on, were discussed. The system could provide accurate isothermal and non-isothermal experiment temperature field and atmosphere for sample reaction. Results showed that the system could achieve precise control of temperature and heating rate in the range of 200- 1 600 ℃ at an accuracy of ±1 ℃ in temperature, ±0.01 L/rain in gas flow, and ±0. 001 g in mass measurement.
