Abstract
The invention discloses the technique that a kind of electrothermal way produces molybdenum-iron, the technique is comprised the following steps：A, molybdenite be calcined to obtain oxidizing molybdenum ore；B, oxidizing molybdenum ore is crushed after add brown iron oxide, carbon dust and be well mixed；C, in mixed-powder add binding agent it is re-compacted blocking；D, block base is put into high-temperature electric heat stove and carries out melting and can obtain molybdenum-iron.The technique that a kind of electrothermal way of the present invention produces molybdenum-iron, after by the way that molybdenite is calcined powder processed and with brown iron oxide, carbon dust is uniform mix after be made block molybdenum-iron obtained by high-temperature electric heat furnace smelting again, not only equipment is simple, the preparation technology cycle is shorter, and operation difficulty is low, environment friendly and pollution-free, manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of metallurgical method, more particularly to a kind of technique of molybdenum-iron production.
Background technology
Main aluminothermic process is prepared ferro-molybdenum at present, and its thermal source is mainly aluminium and silicon, and its required equipment is not only complicated but also cost is high, and pollution of the product to environment is also larger, thus its serious non-compliance energy-conserving and environment-protective production theory.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of needed for equipment is simple and free of contamination electrothermal way produces molybdenum-iron technique.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of electrothermal way produces the technique of molybdenum-iron, comprises the following steps：A, molybdenite be calcined to obtain oxidizing molybdenum ore；B, oxidizing molybdenum ore is crushed after add brown iron oxide, carbon dust and be well mixed；C, in mixed-powder add binding agent it is re-compacted blocking；D, block base is put into high-temperature electric heat stove and carries out melting and can obtain molybdenum-iron.
Preferably, molybdenum oxide miberal powder, brown iron oxide, the mass ratio of carbon dust are 3 in the step B:1:1 or 4:1:1.
Preferably, the electrothermal furnace used in the step D is plasma electrothermal furnace.
Compared with prior art, the technique that a kind of electrothermal way of the present invention produces molybdenum-iron, after by the way that molybdenite is calcined powder processed and with brown iron oxide, carbon dust is uniform mix after be made block molybdenum-iron obtained by high-temperature electric heat furnace smelting again, not only equipment is simple, the preparation technology cycle is shorter, environment friendly and pollution-free and operation difficulty is low, manufacturing cost is low.
