This technique has two prominent problems: titanium"s burning loss and high temperature melt treatment (up 1873K). The author puts forward melting protective cover used by plant ash which can insulate air and enhance effect of heat preservation effectively. At the same time, the author chooses alkalinous magnesite for furnace lining which can avoid redox reaction between silicon oxide (SiO2) and titanium, improve fireproofness of furnace lining and decrease titanium"s burning loss ratio.
针对制备工艺的两个突出问题:Ti元素的烧损问题和高温熔体处理问题(1873K以上),提出利用草木灰作为熔炼的覆盖剂,能有效地隔离空气,强化保温效果,同时选用碱性镁砂炉衬,提高了炉衬的耐火度,克服了酸性炉衬中SiO_2与Ti元素的氧化还原反应,降低了Ti元素的烧损率。

During the actual production, that the oxygen contamination from the crucible material by heat composition increases the oxygen content of molten steel will result in melting losses of the alloys in the molten steel, and will results in more heavier melting losses of the alloys, incontrollable exact chemical content of molten steel, increment of oxide inclusions and bad processability and serviceability, especially in the high strength(σb≥1600MPa) steels and alloys with special performance used in aerospace industry, manufacturing industry for precision instruments and meters, military industry, nuclear industry etc. because these steels usually have a high content of some active alloys such as Ti, V, Nb, Al, RE, etc. and a nearly zero content of dissolved oxygen.
实际生产中,如果炉衬热分解向钢液供氧,势必会造成钢液中合金元素的烧损,尤其是在航空航天、精密仪器仪表制造、军工及核工业部门使用的某些具有特殊性能的高强度(抗拉强度σb≥1600MPa)合金或钢材,因它们通常需要具有较高的活泼合金元素(如Ti、V、Nb、Al、RE等)含量,且钢中溶解氧含量接近于零,炉衬热分解供氧将造成这些合金元素的大量烧损,其结果是钢液化学成分难以精确控制,并增加了氧化物夹杂含量,恶化了钢的加工和使用性能。

FeSi nanoparticles were synthesized via thermal decomposition of iron pentacarbonyl in the solution of dioctyl ether, stabilizers oleic acid and oleylamine. The TEM images showed that FeSi nanoparticles had cubic shape, but it seemed that the composition was not uniform. According to the EDS results, the Fe:Si ratio of gray-uniform nanopaiticles was almost 1:1, and blacker FeSi nanoparticles contained more Fe atoms. Although FeSi didn't have uniform structure, it still could be proved that the incorporation of Fe and Si existed in a single nanoparticle. All possible structure, lattice, binding, morphology, surface condition would be discussed. These results indicated that perhaps FeSi2 was the main structure of the new products; however, due to incompletely combination and less synthesized time, it might still contain some part of Si and Fe structure. Besides, FeSi nanoparticles preserved the optical properties from Si atoms, but the PL intensity was much lower. The maxima PL peak appeared at 388 nm with the excitation at 300 nm. Their saturation magnetization, remanent magnetization and coercivity were measured by the SQUID, exhibiting their nearly superparamagnetic behavior.
利用热裂解系统可成功将研磨矽奈米粒子及五羰铁结合,制备出铁矽奈米粒子;从穿透式显微镜照片可知其粒子呈现立方体型态,但颜色深浅及组成不均,EDS结果则显示颜色均匀之粒子铁与矽之组成大致为1:1,颜色较深之粒子则含有较高量的铁元素;尽管组成比例并不统一,但单颗粒子同时含有矽与铁两种元素,初步说明铁矽奈米粒子之形成;进行多种结构与表面分析并探讨所有可能之键结、结构及表面元素后,推测铁矽奈米粒子可能以FeSi2之结构形成,并同时包含未重组完成的矽及铁之结构;利用PL分析得知铁矽奈米粒子确实保留矽之放光特性,并在300 nm激发光源下,於波长388 nm处有一最强放光特性峰,但整体发光效益不及研磨矽奈米粒子之结果;最后,利用超导量子干涉磁化仪量测其饱和磁化量、残留磁化量、与矫顽磁力,发现磁滞现象并不明显而几乎呈超顺磁性。
