摘要
微波加热钛渣制备人造金红石具有均匀高效、能耗较低等突出优势。在不同条件下,钛渣在微波场中呈现出不同的升温特性,以钛渣为研究对象,系统地分析了微波输出功率、钛渣粒度以及物料量等参数对其微波吸收性能的影响,研究表明,增加微波输出功率有利于增加钛渣在微波场中温度升高的速率;物料量增多会导致钛渣在微波场中温度升高的速率变慢;钛渣粒度减小同样不利于其在微波场中加速升温。
Microwave heating of titanium slag to prepare artificial rutile has the outstanding advantages of uniform high efficiency and low energy consumption.Under different conditions,titanium slag exhibits different temperature rise characteristics in the microwave field.Using titanium slag as the research object,the effects of microwave output power,particle size of the titanium slag and material quantity on the microwave absorption performance of the slag were systematically investigated.The results show that increasing the microwave output power is beneficial to increase the heating rate of titanium slag in the microwave field,while the increase of material quantity will cause a decrease in the rate of temperature rise of titanium slag,and the reduction of particle size is also adverse to the temperature rise of titanium slag in the microwave field.
