【摘要】：金红石是一种短缺的自然资源,以钛渣、钛铁矿等为原料生产人造金红石的研究和实践情况不断见诸报道。为了推动人造金红石生产技术的进步,对几种常见的人造金红石制备和生产技术进行了介绍,指出了这些技术的主要优缺点:(1)电热法生产人造金红石虽说"三废"少,工艺技术容易掌握,但其用电量大,生产的人造金红石品位较低,只能作为电焊条表面涂料。(2)酸浸法可获得高品位的人造金红石,但其副流程长,生产成本较高,生产过程中设备腐蚀严重,因而限制了该工艺的工业化应用。(3)亚熔盐法工艺流程较长,添加剂用量大。(4)选择性析出技术存在流程较长,能耗较高,酸耗较大等问题。(5)微波加热技术具有工艺流程简单,产品品质优良,生产能耗低,制备效率高,无环境污染等优点,是一项很有前景的人造金红石生产技术,但目前还仅局限于实验室试验阶段,因此,应加大工业化应用的研究力度。
[Abstract]:Rutile is a kind of shortage of natural resources. The research and practice of producing artificial rutile from titanium slag and ilmenite have been reported. In order to promote the progress of artificial rutile production technology, several common synthetic rutile preparation and production technologies are introduced. The main advantages and disadvantages of these technologies are pointed out: (1) the "three wastes" of artificial rutile production by electrothermal method are less, The technology is easy to master, but its electricity consumption is large, the grade of manufactured rutile produced is low, it can only be used as surface coating of electrode. (2) High-grade artificial rutile can be obtained by acid leaching method, but its secondary process is long and the production cost is high. Due to the serious corrosion of the equipment in the production process, the industrial application of the process is limited. (3) the process of submolten salt process is longer and the amount of additives is large. (4) the selective precipitation process has long process and high energy consumption. (5) Microwave heating technology has the advantages of simple process, good product quality, low energy consumption, high preparation efficiency and no environmental pollution, so it is a promising artificial rutile production technology. But at present, it is limited to the stage of laboratory test, so we should strengthen the research of industrial application.
