Following the approving of baotou municipal bureau of environmental protection and baotou municipal office of rare earth , baotou jintai rare earth co . , ltd was set up in 1999 and went into production in february , 2000 . it lies in the north of 761th km on no . 110 country road . jintai has a rare earth separation line with a capacity of 3000 ton rare earth cholride per year and enable to produce oxides , carbonates and chlorides of lanthanum , cerium and neodimium , rare earth chloride rich la and ce , rare earth carbonate rich la and ce , samarium - euranium - gadolinium concentrate and rare earth chloride poor zn and mg 包头市金泰稀土有限责任公司于1999年经包头市环保局包头市稀土办公室批准成立，于2000年2月正是投入生产，是包头市稀土行业唯一一家环保验收企业。公司位于110国道761公里往北1公里处，占地面积200亩。
Basing on the government s support and our effort for these years , the output has gradually increased from 800 ton in 1994 to 3000 ton in 2000 . especially in 1999 , the company invested 2 . 8 million yuan rmb emphasizing in technical reform , and set up a neodymium and samarium grouped separation production line to produce a new serious products of low - zinc and low - magnesium rare earth chloride . now the company formed a complete set of service system production to marketing . presently our products has saled covering shandong , shanghai and jiangsu province etc . the company totally possesses 7 million yuan of fized assets and 6 million yuan of circulating capital , and a steady and experienced technical and management team including 2 senior engineer , 3 engineers and 5 other technicians 1999年以来加大了技术改造，新投入280万元建成了钕钐分组线一条，生产低锌、低镁氯化稀土。 2000年追加技改投资580多万元，建成了3000吨萃取分离线，可生产稀土系列产品。企业现有固定资产1480多万元，流动资金1000多万元，高级工程师5名，工程师3名，大中专专业人才20余名。
By analyzing the microstructure of as - cast alloys with different surplus of samarium added , the optimum surplus of samarium is decided . by comparing the microstructure of the alloys annealed for different time , the ideal and economical annealing time is confirmed . the microstructure and phase composition of alloys during the whole preparation of sm2fe17nx are analyzed using the scanning electron micrograph with energy - dispersive x - ray analysis and x - ray diffraction patterns 本论文首先就熔炼工艺参数对铸态组织微结构的影响进行了探讨，并制定出一套较为合适的熔炼工艺；通过对不同钐加入量的铸态组织微观结构的观察分析，确定了原料配置过程中钐的最佳补偿量；通过对采用不同退火时间的合金组织进行比较，确定了理想、经济的退火时间；同时还利用扫描电子显微图像和x射线衍射图谱，比较了整个制备过程中，试样微结构和相组成的变化情况。
