Abstract
The present invention relates to a steel liquid cleaning agent made by smelting a plurality of common raw materials in a purpose-made intermediate frequency furnace. The cleaning agent is mainly used for the end deoxidation of steel liquid. The production method of the cleaning agent comprises: celite, lime, barite and dolomite are used as main raw materials; fluorite, coke particles, etc. are used as assistant materials by working processes such as mixture, smelting, furnace delivery casting, etc. The cleaning agent is a novel efficient steel liquid cleaning agent, a deoxidizing agent and a desulfurizing agent. The present invention absorbs impurities in steel, enhances the fluidity of steel water, improves the forms of the impurities in the steel, cleans the steel liquid and enhances steel quality.
Description
Technical field
The invention belongs to metallurgy industry agent for purifying molten steel production field, relate to a kind of production technique and employed equipment of silicon calcium barium magnesium liquid steel scavenging agent.
Background technology
At present, the production technique of China's Si-Ca-Ba-Mg mainly is to use the hot stove production in ore deposit, Si-Ca-Ba-Mg power consumption height and unstable product quality that this method is produced, the present invention's employing are that the intermediate frequency furnace production Si-Ca-Ba-Mg of liner reduces power consumption greatly with the plumbago crucible, and constant product quality.
Along with the development of steel market, can produce the low Si-Ca-Ba-Mg of cost is the serious hope of manufacturing enterprise always, and the inventor is exactly production technique and an employed equipment thereof of having invented the silicon calcium barium magnesium liquid steel scavenging agent in this case.
Summary of the invention
Be to provide a kind of quality of production stable order of the present invention, the smelting process of the silicon calcium barium magnesium liquid steel scavenging agent that cost reduces, this mainly comprises the improvement of the smelting technology and the equipment of silicon calcium barium magnesium liquid steel scavenging agent.
The present invention is achieved in that the production technique of silicon calcium barium magnesium liquid steel scavenging agent of the present invention, comprise that raw material is selected for use, batching, melting, tapping casting operation, it is characterized in that raw material comprises silica, lime, barite, rhombspar, fluorite, burnt grain, its weight percent is:
Silica: lime: barite: rhombspar: fluorite: burnt grain=5: 5: 5: 5: 2: 2.
After the raw material of aforementioned proportion mixed, drop in the intermediate frequency furnace, through 1400～1800 ℃ furnace temperature condition meltings 1.5-2 hour, treat that raw material turns to liquid and reaction finishes after, can come out of the stove behind cast, the cooling forming, be broken into product; Its product compositional characteristic is: silicon-dioxide 25-65%, calcium oxide 20-48%, barium oxide 2-20%, magnesium oxide 2-20%, surplus is aluminium, sulphur, phosphorus and/or carbon.
The invention has the advantages that: once drop into raw material with ratio of components accurately, make constant product quality, reduced unnecessary operation, reduced power consumption, improved output.
Embodiment
Production technique of the present invention comprises: 1, raw material is selected for use; 2, batching: 3, melting: 4, four aspects of tapping casting.
1, raw material is selected for use: raw material comprises raw materials such as high quality silicon stone (or quartz sand, roast silica), carbonate-free lime, barite, rhombspar, fluorite, Jiao Li.
Ingredient requirement is as follows: silica: SiO
2＞97%
Lime: Cao＞80%
Barite: BaSO
4＞90%
Rhombspar: MgO＞15%
Fluorite: CaF
2＞80%
Burnt grain: fixed carbon＞80%
2, batching: the content according to the silicon of the silicon calcium barium magnesium liquid steel scavenging agent that will produce, calcium, barium, magnesium can suitably be adjusted ratio of components.Just putting into crusher for crushing after finishing by ratio of components batching, to become granularity be that 80-120 purpose meal is stand-by.
3, melting: the raw material input after will pulverizing has in the intermediate frequency furnace of electrode graphite crucible lining, throws full fire door with raw material and is as the criterion, and then furnace temperature is raised to 1400-1800 ℃ after 1.5-2 hour the molten stove of producing.
4, tapping casting: treat raw material melt fully be in a liquid state after, intermediate frequency furnace is tilted, liquid is poured in the ingot mould.
5, crushing packing: after treating the product cooling caking in the ingot mould, carry out crushing packing.
It is the intermediate frequency furnace of liner that the improvement of melting equipment of the present invention is to use with the electrode graphite crucible.It is characterized by: crucible is that Graphite Electrodes makes after inside hollows out.
Example: require to produce calcic more than 25; Baric is more than 15; Contain the silicon calcium barium magnesium liquid steel scavenging agent of magnesium more than 5.At first choose SiO
2＞97% silica 50kg:CaO＞80% lime 50kg; BaSO
4＞90% barite 50kg; MgO＞15% rhombspar 50kg; CaF
2＞80% fluorite 20kg: the burnt grain 20kg of fixed carbon＞80%.Putting into crusher for crushing after above raw material mixed, to become granularity be 80-120 purpose meal, raw material input after pulverizing is had in the intermediate frequency furnace of electrode graphite crucible lining, throw full fire door with raw material and be as the criterion, come out of the stove after melting 1.5-2 hour after then furnace temperature being raised to 1400-1800 ℃ and product.
The product that this examples produce goes out is calcic 26.38% after chemically examining, and baric 16.32% contains magnesium 8.21%.
