Abstract
A process for preparing low-carbon ferromanganese includes adding the electrolytic metal manganese, finished iron product, and auxiliary charge/raw material to high-temp electric induction furnace by different technologies, and smelting and 1300-1800 deg.C. Its advantages are high Mn content up to (70-99.8%), simple process, and high quality of product.
Description
Technical field: the present invention relates to the ferroalloy smelting method, be specifically related to the improvement of low carbon ferromanganese (or claiming little carbon ferromanganese) smelting technology method.
Background technology: at present; the difference that traditional both at home and abroad low carbon ferromanganese is smelted by processing method and smelting equipment has electric furnace process (electro-silicothermic process); shaking ladle process; shaking ladle-electric furnace process; blow oxygen etc.; it respectively has the advantage of oneself; but its common shortcoming is: the basic raw material that is adopted is manganese ore; manganese-silicon; the process of smelting all relates to redox; the chemical reaction of class complexity such as polyphase equilibrium; often need to add auxiliary furnace charge/raw material (as slag former; refrigerant etc.); therefore; all exist technology controlling and process factor complexity; technical process is long; system's required equipment is many; facility investment is big; the finished product grade is difficult to control and improves; abandon manganese content height (usually more than 8%) in the waste residue; the manganese yield is low; shortcomings such as environmental pollution is serious can not adapt to fierce competitive market and requirement on environmental protection.
Summary of the invention: at the above-mentioned shortcoming of prior art, technical problem to be solved by this invention is to provide a kind of smelting process not relate to complex chemical reaction, single, the essentially no environmental pollution of processing step, the higher method with induction furnace production low carbon ferromanganese of final product quality substantially.
For this reason, technical solution of the present invention is: a kind of method of producing low carbon ferromanganese with induction furnace, comprise that will contain manganese raw material, iron-bearing material and auxiliary furnace charge/raw material adds in the high temperature furnace by different process, according to certain process conditions until the low carbon ferromanganese finished product of producing required index, it is characterized in that: the described manganese raw material that contains is the electrolytic metal Mn finished product, and described iron-bearing material is a constituent content irony finished product up to standard.
Described electrolytic metal Mn finished product is GB one-level/secondary electrolytic manganese, inferior manganese sheet and granular electrolytic manganese; Described high temperature furnace be in the following induction furnace any: high frequency, intermediate frequency, line frequency furnace.
The smelting temperature of described high temperature furnace is controlled at 1300 ℃～1800 ℃.
The adding ratio of described ferriferous raw material can be in 5%～30% range regulation of total charge weight, and the manganese content of described low carbon ferromanganese finished product can be in 70%～99.8% range regulation.
After having adopted aforesaid method to improve, the present invention has following advantage:
Owing to produce low carbon ferromanganese after directly adopting highly purified electrolytic metal Mn and the fusion of high purity irony, substantially do not need to add other auxiliary furnace charge/raw material (as slag former, refrigerant etc.), substantially do not relate to complex chemical reaction, so can only adopt an induction furnace to get final product output high-quality finished product as the high temperature furnace, the harmful element in the finished product (C, Si, S, P) content can reduce by tens percent to two orders of magnitude than currently available products;
Simple, lower, the less investment of price of system device, and Production Flow Chart is short, process control condition is simple, easy and simple to handle, production cost is low, essentially no environmental pollution;
Because there is not the polyphase equilibrium problem, so can 5%～30% on a large scale in the adjusting high-purity irony the adding ratio, to satisfy the requirement (Mn from 70%～99.8%, Fe from 8%～18%) of user, market adaptability and competitive capacity have been strengthened greatly to the different grades of low carbon ferromanganese finished product;
And method of the present invention has manganese yield height, the advantage that energy consumption is low, and the marketing prospect is long-range.
Embodiment: specific embodiments of the invention: with the electrolytic manganese 200kg of manganese content 99.7%, add iron and steel 25kg, drop into about 50 minutes of the interior melting of medium-frequency induction furnace, look and form in its whole stove behind the molten bath in the impouring mold, treat the complete hardening by cooling hypsokinesis of alloy mould, the piece footpath (being generally 5～20mm/ piece or 10～50mm/ piece) that is crushed to customer requirement is finished product, and the chemical ingredients measured data of low carbon ferromanganese finished product is as follows:
C：0.03％～0.042％， Si：0.09％～0.11％，
P：0.0016％～0.011％， S：0.015％～0.018％，
Mn：82％～91.01％， Fe：8.3％～17.02％；
The data of Chang Yong ad eundem low carbon ferromanganese relatively:
C：≤0.10％， Si：≤1.5％， P：≤0.1％，
S：≤0.02％， Mn：80％～85％，
As seen, the low carbon ferromanganese of producing with processing method of the present invention is much better than other equivalents.
