发明名称 POST-SINTER CONGLUTINATION AND OXIDATION-PREVENTATIVE VANADIUM-NITROGEN ALLOY PREPARATION METHOD
摘要 <p>Disclosed is a post-sinter conglutination and oxidation-preventative vanadium-nitrogen alloy preparation method, comprising the following steps: (1) mixing a vanadium-containing compound, bonding agent, and pre-mixed carbon reducing agent and compressing the mixture into raw materials balls, and naturally air-drying the raw materials balls containing vanadium-containing compound and the bonding agent; (2) mixing the raw materials balls and granulated carbon reducing agent and continuously feeding the mixture into the vertical kiln of an intermediate frequency induction furnace, and supplying high-purity nitrogen, the material being fed and the product being discharged once every 6 to 8 hours, and the process occurring in three stages: drying, carbonization and nitrogenization, and cooling. The method can reduce production cost and increase production efficiency.</p>
