Problems solved by technology

[0005] The object of the present invention is to provide a fluorine-free, low-nitrogen and sulfur ferromolybdenum smelting raw material, a ferromolybdenum green smelting system and a ferromolybdenum green smelting method, and solve the problems in the prior art by designing a fluorine-free, low nitrogen and sulfur ferromolybdenum smelting raw material. The existing ferromolybdenum smelting more or less uses saltpeter as a heating agent, and a certain amount of nitrogen dioxide gas is produced after the saltpetre reaction. In addition, the environmental protection equipment is not in place, which will cause a certain amount of nitrogen dioxide to be emitted to the air, causing environmental pollution

Abstract

The invention relates to the technical field of ferromolybdenum smelting, in particular to a fluoride-free low-nitrogen-sulfur ferromolybdenum smelting raw material, a ferromolybdenum green smelting system and a ferromolybdenum green smelting method. The method discloses a high-temperature-resistant magnesium alloy which comprises 4-5 parts of molybdenum oxide, 0.2-0.4 part of quick lime, 1.2-2 parts of iron phosphorus, 0.5-1.2 parts of metal silicon powder, 0.2-0.4 part of aluminum particles, 0.4-0.9 part of steel scraps and 0.05 * 10 <-3 >-0.25 * 10 <-3 > parts of magnesium bars. Through thedesign of the fluoride-free low-nitrogen-sulfur ferromolybdenum smelting raw material, the problems that in the prior art, in current ferromolybdenum smelting, more or less nitratine is used as a heat supplementing agent, a certain amount of nitrogen dioxide gas is generated after the nitratine reaction, environment-friendly equipment is not in place, a certain amount of nitrogen dioxide is discharged into air, and the environment is polluted are solved; and meanwhile, in order to improve the fluidity of slag in traditional smelting, fluorite can be used, and calcium fluoride in the fluoritecan pollute the environment to a certain extent as well.

Description

technical field [0001] The invention relates to the technical field of ferromolybdenum smelting, in particular to a fluorine-free, low-nitrogen and sulfur ferromolybdenum smelting raw material, a ferromolybdenum green smelting system and a ferromolybdenum green smelting method. Background technique [0002] At present, ferromolybdenum smelting uses more or less saltpeter as a heating agent. After the reaction of saltpeter, a certain amount of nitrogen dioxide gas is produced. In addition, environmental protection equipment is not in place, which will cause a certain amount of nitrogen dioxide to be emitted into the air. , causing environmental pollution. At the same time, traditional smelting uses fluorite to improve the fluidity of slag, and the calcium fluoride in fluorite will also cause certain pollution to the environment. [0003] In addition, the materials required for ferromolybdenum smelting are relatively fine and dry, and a certain amount of dust will be generate...
