Abstract
Provided is a method for smelting metal waste into steel. Metal waste is placed into a steel making furnace to be molten and form molten metal waste, and a soluble metal salt is placed into the molten metal waste. The method is characterized in that precipitate is dried and treated to be particles, low-temperature plasma reduction treatment is performed to the particles, hydrogen is added to convert a compound containing metal into an oxidized molten metal, potassium permanganate is added to perform smelting, and then the low-temperature plasma reduction treatment is performed to produce qualified steel. Compared with the prior art, the method for smelting the metal waste into the steel has the prominent advantages of being low in processing temperature, simple in process, low in production cost, short in treatment time, high in production efficiency, free of environmental pollution and the like.
Description
Technical field
The present invention relates to a kind of recovery method of noble metal, particularly a kind of method of utilizing Low Temperature Plasma Treating technology for recovery copper.
Background technology
As everyone knows, steel has a kind of very high industrial application value, in industrial production, can produce a large amount of scrap metal pieces, goes out of use, and has not only caused waste, also can produce environmental pollution.Therefore, from scrap metal pieces, smelt steel, turn waste into wealth, turn bane into boon, beyond doubt a positive and significant thing.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of practical, processing efficiency is high, and cost is low, and does not produce the method for the scrap metal pieces smelting steel of environmental pollution.
For achieving the above object, scrap metal pieces of the present invention is smelted the method for steel, and the technological power case of employing is:
A kind of scrap metal pieces is smelted the method for steel, melts putting into steel melting furnace in the scrap metal pieces, generates metallic wastewater; Put into soluble metallic salt, it is characterized in that: after drying precipitate is processed into particulate state, it is carried out plasma deoxidization in low termprature handle; Add hydrogen, be converted into oxidized metal water to the containing metal compound, add potassium permanganate and smelt; Carry out plasma deoxidization in low termprature again and handle, so just smelt into qualified steel.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
Compared with prior art, have that processing temperature is low, technology is simple, production cost is low, the treatment time is relatively shorter, production efficiency is high, and outstanding advantage such as non-environmental-pollution.
Embodiment
A kind of scrap metal pieces is smelted the method for steel, melts putting into steel melting furnace in the scrap metal pieces, generates metallic wastewater; Put into soluble metallic salt, it is characterized in that: after drying precipitate is processed into particulate state, it is carried out plasma deoxidization in low termprature handle; Add hydrogen, be converted into oxidized metal water to the containing metal compound, add potassium permanganate and smelt; Carry out plasma deoxidization in low termprature again and handle, so just smelt into qualified steel.
