Abstract
The invention relates to a method for producing micro-carbon ferromanganese, which takes an electrolytic manganese metal piece or electrolytic manganese metal powder as raw material, and comprises the steps of: adding 0.5-20% of iron into the raw material; adopting an intermediate frequency furnace to enable the electrolytic manganese metal piece and the iron to be melted; during ingot casting, scattering the electrolytic manganese metal piece or electrolytic manganese metal powder into a casting mould while casting; forming a whole cast ingot by enabling the electrolytic manganese metal piece or electrolytic manganese metal powder to be coated by molten micro-carbon ferromanganese; and finally, crushing the cast ingot into the micro-carbon ferromanganese. Compared with the micro-carbon ferromanganese completely prepared by a melting method, the product prepared by the method provided by the invention is lower in impurity content and has the same antioxidation performance; and the energy consumption of every ton products can be greatly reduced.
Description
Technical field
The invention belongs to field of metal casting technology, be specifically related to a kind of method of producing little carbon ferromanganese.
Background technology
At present, add the little carbon ferromanganese of the direct ingot production of scorification of iron with electrolytic metal Mn sheet or electrolytic metal manganese powder, product energy consumption per ton is high.
Summary of the invention
Add iron with the little carbon ferromanganese of the direct ingot production of scorification in order to solve electrolytic metal Mn sheet or electrolytic metal manganese powder, the deficiency that product energy consumption per ton is high, the present invention provides a kind of method of producing little carbon ferromanganese.
The technical solution adopted for the present invention to solve the technical problems is: do raw material with electrolytic metal Mn sheet or electrolytic metal manganese powder; Add 0.5% ~ 20% iron, adopt intermediate frequency furnace with electrolytic metal Mn sheet and iron fusion, when ingot casting; The limit casting; The limit is sprinkled into electrolytic metal Mn sheet or electrolytic metal manganese powder in the mold, and little carbon ferromanganese parcel electrolytic metal Mn sheet of fused or electrolytic metal manganese powder form the ingot casting of an integral body, again ingot casting are broken into little carbon ferromanganese.With compare with little carbon ferromanganese of scorification production fully, its product foreign matter content is lower slightly, the product antioxidant property is identical, product energy consumption per ton will reduce greatly.
The invention has the beneficial effects as follows, reduce scorification greatly and produce little carbon ferromanganese energy consumption and production cost, and do not influence the use properties of little carbon ferromanganese product.
Embodiment:
Embodiment 1: with 1 ton of electrolytic metal Mn sheet; Be broken into the electrolytic metal manganese powder with its 600 kilograms; 400 kilograms of electrolytic metal Mn sheets and 20 kilograms of iron are used the intermediate frequency furnace fusion, during ingot casting, 600 kilograms of electrolytic metal manganese powders are sprinkled in the mold; The little carbon ferromanganese parcel of fused electrolytic metal manganese powder forms the ingot casting of an integral body, again ingot casting is broken into little carbon ferromanganese.
Embodiment 2: with 1 ton of electrolytic metal Mn sheet; 600 kilograms of electrolytic metal Mn sheets and 30 kilograms of iron are used the intermediate frequency furnace fusion; During ingot casting; With distributor 400 kilograms of electrolytic metal Mn sheets are sprinkled in the mold simultaneously, the little carbon ferromanganese parcel of fused electrolytic metal Mn sheet forms the ingot casting of an integral body, again ingot casting is broken into little carbon ferromanganese.
Claims (1)
1. the working method of a little carbon ferromanganese is characterized in that: do raw material with electrolytic metal Mn sheet or electrolytic metal manganese powder, add 0.5% ~ 20% iron; Adopt intermediate frequency furnace with electrolytic metal Mn sheet and iron fusion; When ingot casting, the limit casting, the limit is sprinkled into electrolytic metal Mn sheet or electrolytic metal manganese powder in the mold; Little carbon ferromanganese parcel electrolytic metal Mn sheet of fused or electrolytic metal manganese powder form the ingot casting of an integral body, again ingot casting are broken into little carbon ferromanganese.
