Method for preparing boron carbide powder by adopting vertical smelting furnace
The invention relates to a method for preparing boron carbide powder by adopting a vertical smelting furnace, and belongs to the field of preparation of boron carbide materials. The method comprises the following steps: uniformly mixing a boron source material and a carbon source material; after a furnace top sealing cover covers the top end of the furnace body, a graphite electrode is inserted and is in contact with a bottom plate valve; after the raw materials are put into the furnace body, voltage and current are adjusted for heating; in the heating period, along with the temperature rise of the smelting raw materials, according to different temperature stages, the graphite electrode is lifted through an automatic lifting device, and the insertion depth of the graphite electrode is dynamically adjusted; and heating to 1900-2300 DEG C to obtain the boron carbide material. In the process of preparing the boron carbide through the method, the position of the graphite electrode is dynamically adjusted through the automatic lifting device so as to accurately control the crystallization process and the smelting process of the boron carbide, the generated boron carbide product is taken out through the bottom discharging device, and the method has the advantages of being simple in process, high in temperature rising speed, capable of achieving large-scale production and the like.
本发明涉及一种采用立式冶炼炉制备碳化硼粉体的方法，属于碳化硼材料制备领域。该方法为：取硼源材料与碳源材料混合均匀；在炉体顶端盖上炉顶封闭罩后，插入石墨电极，并与底板阀接触；将原料装入炉体后，调整电压电流进行加热；加热期间随着冶炼原料温度的升高，根据不同的温度阶段，通过自动升降装置对石墨电极进行提升，动态调整石墨电极插入深度；加热至1900~2300℃，即可得到碳化硼材料。通过该方法制备碳化硼的过程中通过自动升降装置动态调整石墨电极位置，以精准控制碳化硼的结晶过程和冶炼工艺制程，生成的碳化硼产品通过底部卸料装置取出，具有工艺简单，升温速度快，可以规模化生产等优点。
