in the furnace for 45 min to permit the complete dissolution of Cu in the melt. Similar procedure was adopted in the subsequent addition of Ni. This step was repeated three times to guarantee......
Biochar was produced using rice straw, which was pyrolysed at 300 °C for 1 h (17 °C/min) in a high-performance muffle furnace (SX 2-5-12, Yuandong Therm Corporation in Changsha, China). Biochar (10 g......
炉型使用等离子体喷枪替代传统炼钢炉的石墨电极,简化了炼钢炉的整体结构,所炼制金属的品质可达到真空熔炼的效果.但由于熔炼产生的液态金属与耐火材料铺砌底座与炉壁之间发生接触,导致金属被液态金属与炉衬交界处产生的反应物质所污染. 图2 等离子电弧炉结构示意图[18] Fig. 2 Structure diagram of plasma arc furnace[18] 由于传统的...;Schematic diagram of plasma induction furnace[20] 等离子体熔炼技术已在国内外多家冶金企业中得以应用.早在20世纪60年代,原民主德国的Freital钢铁厂采用配备有水冷钨阴极转移弧等离子体枪来熔炼废钢,功率达到4 MW级,阳极寿命大于100 h,年产钢约60000 t[21].之后,采用等离子体作为热源的等离子体熔融还原法也逐步在矿石还原工业中得以应用.20世......
the contact between the sample and the external environment, the crucible was placed in a furnace to heat to the designed temperature and the temperature was held for the designed time. The results revealed......
) [128]. ZHOU et al [129] found another way to produce VN powder by calcining V2O5 xerogel in a furnace under an anhydrous NH3 atmosphere at 400 °C. The specific capacitance of VN reached 161 F/g at 30......
