Abstract
The present invention relates to a compound deoxidant produced by reduction reaction in a purpose-made intermediate frequency furnace from a plurality of common raw materials. The deoxidant is mainly used for the end deoxidation of steel liquid. The deoxidant comprises is produced by the working procedures comprising mixing, smelting, casting from the furnace, etc by the main raw materials comprising silica, lime, barite and dolomite and the assistant materials comprising fluorite, coke particles, etc. The deoxidant is a novel efficient compound deoxidant and a desulfurizer. The deoxidant can absorb impurities in steel, increase the fluidity of steel water, improve the forms of impurities in steel, purify steel liquid and increase steel quality.
Description
Technical field
The invention belongs to metallurgy industry reductor production field, relate to a kind of production technique of Si-Ca-Ba-Mg composite deoxidant.
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.
Summary of the invention
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 the production technique of having invented the Si-Ca-Ba-Mg composite deoxidant in this case.
The object of the present invention is to provide a kind of quality of production stable, the smelting process of the Si-Ca-Ba-Mg composite deoxidant that cost reduces.
The invention has the advantages that: it is that the disposable batching of intermediate frequency furnace of interior benefit is produced silico-calcium barium power consumption is reduced greatly that the present invention adopts with plumbago crucible, and constant product quality, has reduced unnecessary operation, has improved output.
The production technique of Si-Ca-Ba-Mg of the present invention comprises raw material crushing, mixing, melting temperature raising, packing warehouse-in operation.Raw material comprises silica, lime, barite, rhombspar, fluorite, Jiao Li etc., and its weight percent is a silica: lime: barite: rhombspar: fluorite: burnt grain=2.5: 3: 2.5: 2.5: 1: 1.
Production technique of the present invention comprises: 1 raw material is selected for use, 2 batchings, melting, four aspects of 4 tapping casting.
1, raw material is selected for use: raw material comprises silica, lime, barite, rhombspar, fluorite, six kinds of raw materials of burnt grain;
2, ingredient requirement is as follows:
Silica: SiO
2＞97%
Lime: CaO＞80%
Barite: BaCO
4＞90%
Rhombspar MgO＞15%
Fluorite: CaF
2＞80%
Burnt grain: fixed carbon＞80%
2, prepare burden: just put into crusher for crushing after finishing by the ratio of components batching and become granularity 80-120 purpose meal 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 degree back insulations and comes out of the stove after 1 hour.
4, tapping casting: treat after the intermediate frequency furnace inclination liquid in the stove to be poured in the ingot mould after raw material melts fully.
Embodiment
Example: at first choose SiO
2＞97% silica 50kg; The lime 60kg of CaO＞80%; BaCO
4＞90% barite 50kg; The rhombspar 50kg of MgO＞15%; 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, then furnace temperature is raised to that 1400 degree back insulations were come out of the stove after 1 hour 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%.
Claims (1)
1. the production technique of a Si-Ca-Ba-Mg composite deoxidant, comprise that raw material is selected for use, batching, melting, tapping casting operation, it is characterized in that: raw material comprises silica, lime, barite, fluorite, rhombspar, burnt grain, and its weight percent is: silica: lime: barite: rhombspar: fluorite: burnt grain=2.5: 3: 2.5: 2.5: 1: 1.
