Description
Technical field
The utility model relates to silicomangan process units technical field, and in particular to a kind of association type silicomangan
Production system.
Background technology
The production of manganese-silicon, whether as commodity silicomanganese or the semi-finished product as other products, is a silicon all the time
Manganese electric furnace single-body type is produced, that is, go out one stove slag of a stove alloy strip.Silicomanganese electroslag is typically processed by the way of water quenching, water quenching
Afterwards as low price raw material or Solid state fermentation, pollute environment and comprehensive utilization value is relatively low, due to current mid-carbon fe-mn slag and
Other carbon manganese slags are more ripe as the method for manganese-silicon raw materials for production, but silicomanganese electroslag comprehensive utilization technique compared with
It is few, it is most of to coordinate other modes to utilize for silicomanganese electroslag（Such as electrolytic manganese etc.）, apparently DeGrain at present.
Traditional silicomanganese preparation method is：1st, the adjuvant such as manganese ore and coke, Silicon stone is upper to furnace roof material Jing after broken, dispensing
Storehouse, into electric furnace smelting.In ore-smelting electric furnace, the high oxide decomposes of manganese, manganese oxide, silicon oxide and phosphorus pentoxide
Reduced by carbon.Its reaction is as follows：

This utility model the first silicomanganese electric furnace controls basicity of slag in 0.1-0.4, and coke amount of allocating is subtracted by normal rates
Few 5% -10%, in the case where ensureing that the working of a furnace is stable, in making slag, MnO contents are maintained between 20%-28%.Furnace rear silicomanganese is gone out
Electroslag is poured into a mould, and is buckled in iron bucket by smelting personnel after cast（The vehicle frequency is arranged according to the quantity of slag）It is transported to appointed place
Storage is to be broken.As the second silicomanganese electric furnace smelting high silicon manganese-silicon alloy raw material after slag is broken, through burdening calculation, Burden
Example is stepped up with 5% as gradient from the beginning of 10%（It is up to 30%）, while MnO contents are controlled below 10% in slag, carry out
Normal Water Quenching.
The beneficial effects of the utility model：The slag that the low-silicon ferro-silicon-manganesc of carbon containing 1%-2% is produced is crushed, is matched somebody with somebody in proportion
Enter to another production silicon-manganese alloy electric furnace in, using silicon-manganese alloy production temperature it is higher the characteristics of, be passed through oxidation
Reduction reaction, makes full use of the MnO in slag, reaches raising comprehensive recovery, reduces the purpose that electric furnace produces the quantity of slag.Production technology
Control is simple, low cost of manufacture, and product recovery rate is high, and production process slag yields poorly, and preferably resolves waste residue yield excessive

Specific embodiment
Technological means, creation characteristic, reached purpose and effect to realize this utility model is easy to understand, below
With reference to specific embodiment, this utility model is expanded on further.
Reference picture 2-3, this specific embodiment are employed the following technical solutions：A kind of association type silicomangan production system,
Including the first silicomanganese electric furnace 1, the second silicomanganese electric furnace 2, the first furnace top bin 3, the second furnace top bin 4, the first ladle 5, second
Ladle 6, slag ladle 7, the first ingot mould 8, the second ingot mould 9 and water quenching pool 10, the first silicomanganese electric furnace 1, the second silicomanganese electric furnace 2 respectively with
First furnace top bin 3, the second furnace top bin 4 are connected, and the first silicomanganese electric furnace 1 is connected with the second silicomanganese electric furnace 2 by slag ladle 7, the
One silicomanganese electric furnace 1 is also connected with the first ladle 5, and the first ladle 5 is connected with the first ingot mould 8；Second silicomanganese electric furnace 2 respectively with
Second ladle 6, water quenching pool 10 are connected, and the second ladle 6 is connected with the second ingot mould 9.
The core technology of this specific embodiment reduces coke 5-10% coke amount of allocating by technique adjustment, makes silicomanganese electricity
In stove slag, MnO contents are reached between 25%-28%；Adopt low basicity operation simultaneously, coordination electrode position makes the working of a furnace stably transport
OK.
Its concrete technology is as follows：The determination of 1 coke amount of allocating：Reaction in furnace is controlled by losing charcoal mode, slag MnO is made
Content reaches more than 20%.Coke allocate into it is too low occur that electric furnace is underload, the phenomenon such as stove varus slag, the working of a furnace are difficult to stable fortune
OK.Excessively then make reaction in furnace relatively abundant conversely, coke is allocated into, MnO contents are reduced in slag, it is difficult to which reaching next stove that steps into will
Ask.By constantly adjustment coke allocation ratio, grope optimal operating parameter.Empirical tests, reduce 5-10% in the normal amount of allocating of coke
When, while MnO contents in slag can be made to reach more than 20%, it is ensured that the stable operation of the working of a furnace.
The determination of 2 basicity of slags：In silicomanganese electric furnace production process, basicity of slag is normally controlled between 0.6-0.8, with
Ensure slag fluidity, make to come out of the stove smooth.MnO is generated after the high oxide decomposes of manganese, because in silicomanganese smelting furnace material
SiO2 contents are higher, are combined into manganous silicate with MnO.CaO in slag can improve the reducing condition of manganous silicate, by MnO from silicon
Cement out in sour manganese, improve the reaction density of free MnO, be conducive to the reduction of MnO.Suppression is needed in silicon manganese slag production process
The reduction of MnO processed, to realize the raising of MnO contents in slag, meet the high silicon silicomanganese smelting of next step enters stove requirement.Therefore,
Need using low basicity operation between 0.1-0.4 when smelting.But slag reduces causing slag fluidity to reduce, and comes out of the stove not
Freely, affect the stable operation of the working of a furnace.To overcome basicity to reduce the problem of the slag fluidity brought difference, adjusted by furnace charge, made
Electrode is further inserted deeply, is improved in-furnace temperature, is made slag possess higher temperature, so as to improve mobility.
The determination of silicon manganese slag amount of allocating when 3 silicon silicomanganese are smelted：What silicon manganese slag was smelted as high silicon silicomanganese in cooling, after crushing
Raw material, can meet into stove requirement in terms of grade and granularity.But compare:For other manganese ores, grade is relatively low.The higher meeting of amount of allocating
Causing entirety to enter stove manganese grade reduces, and affects smelting index.The relatively low then reduces cost amount of amount of allocating is less than normal, it is impossible to embody resource
The meaning of comprehensive utilization.By being stepped up silicon manganese slag allocation ratio, silicon manganese slag allocation ratio is found out in 15-25%, electric furnace
Global index is the most economical.
The controlling of production process of this specific embodiment is simple, low cost of manufacture, and product recovery rate is high, production process slag
Yield poorly, preferably resolve the excessive problem of waste residue yield, be typical new cleanproduction process, meet national industry development
Require, economic benefit and social benefit are notable.Controlled by technique adjustment and lower slag ratio, contain a silicomanganese electric-furnace slag MnO
Amount is reached between 20%-28%.Slag carries out high silicon manganese-silicon alloy production as another silicomanganese electric furnace raw material Jing cast, after crushing
Use.The total quantity of slag of two silicomanganese electric furnaces is reduced, the target of comprehensive recovery is improved.Jing tests two 16500KVA silicomanganese electricity
Stove comprehensive yield improves 2%, and half a year can nearly million yuan of reduces cost.4100 tons of outer waste discharge slag is reduced simultaneously, realizes the synthesis of resource
Utilize, with good economic and social benefit.
