Abstract
The invention discloses a kind of molybdenum-iron preparation method, the method is comprised the following steps：A, 30-40 according to the mass fraction parts of molybdenum oxide powder, 20-30 parts of brown iron oxide, 20-30 parts of iron powder, 18-22 parts of calcium molybdate, 15-20 parts of industrial residue, 10-15 parts of carbon dust are uniformly mixed, amount containing molybdenum is 12%-18% in the industrial residue；B, by mixed material carry out in stove smelt, smelting temperature be 1500 degrees Celsius；C, will be separated and obtain molybdenum-iron product after the product cooling after smelting.A kind of molybdenum-iron preparation method of the present invention, by rationally using industrial residue can quickly, efficient, low temperature prepare molybdenum-iron, not only simplify molybdenum-iron smelting equipment and technique, and greatly reduce energy consumption, and environmental pollution is effectively prevent, with remarkable progress.
Description
Technical field
The present invention relates to a kind of metal smelt method, more particularly to a kind of molybdenum-iron preparation method.
Background technology
Molybdenum-iron is widely used at present as a kind of important metallurgical addition agent, and tradition prepares the method predominantly aluminothermic process of molybdenum-iron, but it has many drawbacks, such as influence environment, high energy consumption manufacturing cost high reaction temperature whard to control, pollutant emission higher etc. more.
The content of the invention
The technical problems to be solved by the invention are to provide the relatively low molybdenum-iron preparation method of a kind of process is simple, energy consumption.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of molybdenum-iron preparation method, comprises the following steps：A, 30-40 according to the mass fraction parts of molybdenum oxide powder, 20-30 parts of brown iron oxide, 20-30 parts of iron powder, 18-22 parts of calcium molybdate, 15-20 parts of industrial residue, 10-15 parts of carbon dust are uniformly mixed, amount containing molybdenum is 12%-18% in the industrial residue；B, by mixed material carry out in stove smelt, smelting temperature be 1500 degrees Celsius；C, will be separated and obtain molybdenum-iron product after the product cooling after smelting.
Preferably, in the step B duration of heat be 1-2 hours.
Preferably, being separated using centrifugal separator in the step C.
Compared with prior art, a kind of molybdenum-iron preparation method of the present invention, by rationally using industrial residue can quickly, efficient, low temperature prepare molybdenum-iron, not only simplify molybdenum-iron smelting equipment and technique, and greatly reduce energy consumption, and environmental pollution is effectively prevent, with remarkable progress.
