Preparation method of vanadium carbide and chromium carbide composite material
The invention relates to the technical field of metallurgy, in particular to a preparation method of a vanadium carbide and chromium carbide composite material, which comprises the following steps: 1, uniformly mixing a material containing vanadium and chromium with a carbon raw material, adding a binder, and uniformly mixing to prepare pellets; 2, drying the pellets, putting the pellets into a vacuum furnace, increasing the temperature to 900-1200 DEG C at the constant temperature increasing speed of 350-450 DEG C/h, and conducting heat preservation for 2-4 h; and 3, cooling the pellets under the protection of inert gas, discharging the pellets out of a furnace, and crushing the pellets to obtain the vanadium carbide and chromium carbide composite material. The preparation method of the vanadium carbide and chromium carbide composite material provided by the invention is simple to operate, and the prepared vanadium carbide and chromium carbide composite material is fine in granularity, uniform in particle size, single in composition and low in impurity content, can meet the requirements in the fields of superfine hard alloy, metal ceramic and the like; and has great significance in improving the quality of the vanadium carbide and chromium carbide composite material.
本发明涉及冶金技术领域，尤其涉及一种碳化钒和碳化铬复合材料的制备方法，包括如下步骤：步骤一，将含钒铬的物料和碳原料混合均匀后加入粘结剂，混合均匀后制成球团；步骤二，将所述球团干燥后放入真空炉中，以350～450℃/h的升温速度匀速升温至900～1200℃，保温2～4h；步骤三，将所述球团在惰性气体的保护下冷却出炉，破碎即得到碳化钒和碳化铬复合材料。本发明提供的碳化钒和碳化铬复合材料的制备方法操作简单，制备得到的碳化钒和碳化铬复合材料粒度细，粒径均匀，组成单一，杂质含量少，可以满足超细硬质合金、金属陶瓷等领域的需求，对于提高碳化钒和碳化铬复合材料品质具有十分重要的意义。
