钨铁是冶炼高速工具钢、含钨冲模钢等各种合金钢的主要原料.我国是蕴藏和开采钨砂最多的国家;但在抗战以前尚无自产的钨铁,而且有关冶炼钨铁若干关键性问题的具体资料,在各国的科技文献中也极其缺乏.作者在抗战时期非常困难的生产条件下,首次在国内进行了多次的试炼和改进,总结这一系列实验的经验,对于钨铁生产实践,得到以下的若干结论,并作出若干相应的建议:在冶炼设备方面:对于间歇性生产的钨铁冶炼,主张采用能量在500～1,000千伏安的两相电炉,炉衬以纯净的炭质为最佳,并应装置吸尘设备和采用适当的电压.对于炉渣的选择,提出了参考炼铁炉炉渣成分进行冶炼的建议;并认为应使用炉前分析、严格地控制炉渣的组成和冶炼每批炉料的终点.总结了各种进料操作方法的优缺点,指出采用这些方法的适宜条件.本文探讨了控制钨铁中炭、锰、硫各项成分的具体措施,为了降低硫的含量和保证高度的钨回收率,从生产实践中得出了以食盐代替苏打,并尽量减少萤石的配料部分以粘土代替的初步结论.同时,指出在冶炼前应将原料加以严格的分类和选洗,以保证成品质量的提高.对鉴定成品质量的具体方法作出介绍,并对钨铁的成分规范提出了建议.此外,指出了降低钨铁冶炼成本的主要方向;建议深入地实验和研究炉渣炉尘的处理和利用.本文资料可提供从事冶炼钨铁合金工作者的参考、和有助于今后的正规生产工作.一、前言二、钨铁冶炼技术发展的简述三、冶炼方法概论四、钨铁的试炼五、技术研讨六、结论七、参考文献 Tungsten is the main raw material for smelting high-speed tool steel, tungsten die steel and other alloy steel.Our country is the country that contains and produces the largest amount of tungsten sand, but there is no tungsten iron produced by ourselves before the war, The specific information of the key issues is also extremely lacking in the scientific and technological literature of various countries.The author conducted many trials and improvements in China for the first time under the very difficult production conditions during the War of Resistance Against Japan and summarized the experience in this series of experiments. Some conclusions are drawn as follows, and some suggestions are made accordingly: In the smelting equipment: For the ferro-smelting of intermittent production, it is advocated to adopt the two-phase electric furnace with energy of 500-1,000 KVA, Of the carbonaceous is the best, and should be equipped with vacuum equipment and the use of appropriate voltage for the choice of slag, the reference to the smelting slag composition of iron smelting advice; and that the furnace should be used to analyze and strictly control the slag Composition and smelting the end of each batch of charges.This paper summarizes the advantages and disadvantages of various feeding methods and points out the appropriate conditions for using these methods.This paper discusses the control of carbon, In order to reduce the content of sulfur and ensure the high recovery rate of tungsten, preliminary conclusions were drawn from the practice of using salt instead of soda and minimizing the replacement of fluorite ingredients with clay.At the same time, Before the raw materials should be strictly classified and washed to ensure the quality of finished products to improve the quality of the identification of the specific methods to introduce and make recommendations for the composition of tungsten iron specifications.In addition, The main direction; it is recommended to in-depth experimental study and study of the treatment and utilization of slag furnace dust.This information can provide reference for workers engaged in smelting of ferro-tungsten alloy, and contribute to the formal production work in the future.
