Problems solved by technology

[0002] Ferro-molybdenum alloys are currently prepared by the aluminothermic method. The heat sources are mainly aluminum and silicon. The equipment required is not only complicated but also expensive, and the reaction products pollute the environment. Therefore, it seriously does not meet the production concept of energy saving and environmental protection.

Abstract

The invention discloses a process for producing ferro-molybdenum through an electrothermal method. The process includes the following steps that A, molybdenite is roasted to obtain molybdenum oxide minerals; B, the molybdenum oxide minerals are smashed, ferric oxide powder and carbon powder are added into the smashed molybdenum oxide minerals for uniform mixing; C, a binder is added into mixed powder and then briquetting is performed; and D, a briquetted blank is put in a high-temperature electrothermal furnace to be smelted, and then the ferro-molybdenum can be obtained. By means of the process for producing the ferro-molybdenum through the electrothermal method, the molybdenite is roasted, powdered and uniformly mixed together with the ferric oxide powder and the carbon powder to obtain the mixture, the mixture is briquetted, smelting is performed through the high-temperature electrothermal furnace so as to obtain the ferro-molybdenum, equipment is simple, the period of the preparation process is short, the operation difficulty is low, the environment is protected, pollution is avoided, and the production and manufacturing cost is low.

Description

technical field [0001] The invention relates to a metallurgical method, in particular to a process for producing ferromolybdenum. Background technique [0002] Ferro-molybdenum alloys are currently prepared by the aluminothermic method. The heat sources are mainly aluminum and silicon. The equipment required is not only complicated but also expensive, and the reaction products pollute the environment. Therefore, it seriously does not meet the production concept of energy saving and environmental protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a process for producing molybdenum ferromolybdenum with simple required equipment and no pollution by electrothermal method. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: [0005] A process for producing ferromolybdenum by electrothermal method, comprising the following steps: A, roasting...
