Abstract
The present invention relates to a high-power carburetant and its preparation method. It uses petrol coke whose sulfur content is below 0.6%, volatile matter content is 6-15% and ash content is less than 0.5%, and makes it undergo the processes of heating for 35-45 hr. with electric furnace and natural cooling for 10-14 days so as to obtain the invented product.
Description
The present invention relates to a kind of high-power carburetant that is applicable to production high-quality carbon steel and preparation method thereof.
High-power carburetant is one of main raw that is used for production high-quality carbon steel, the main users of this product is countries and regions such as economy, the relatively advanced U.S. of technology, Japan and Europe in the world, and this also is as long as that developed country's steel product quality is good one of reason.At present the employed high-power carburetant of producer of the carbon steel of production high-quality in the world all is that the chip that will produce in the high power graphite electrode course of processing is processed into certain particle size and forms.But because of its expensive raw material price, the source is poor, and does not satisfy user's demand far away.
Purpose of the present invention provides a kind of cost of material lower at above-mentioned weak point of the prior art exactly, and its resource is than horn of plenty, and can substitute a kind of high-power carburetant of prior art products and preparation method thereof fully.
Purpose of the present invention can adopt following measure to realize:
High-power carburetant of the present invention comprise sulphur content below 0.6%, fugitive constituent between 6-15%, ash is not more than 0.5% refinery coke.
Its preparation method is as follows: with sulphur content below 0.5%, fugitive constituent between 6-15%, ash is not more than 0.5% refinery coke and places in the electric furnace, is finished product through 10-14 days behind the naturally cooling in heating under 2500-3000 ℃ the temperature after 35-45 hour.
Finished product of the present invention is through surveying its sulphur content below 0.05%, and carbon content is more than 98%, and ash is not more than 0.5%, and moisture is below 1%.
It is lower that product of the present invention not only has a cost of material, and resourceful advantage improves China's steel product quality for quickening, for national multiple exit, earn foreign exchange all has important and far-reaching meaning more.
The present invention is described in further detail below with reference to embodiment:
Embodiment 1:
With sulphur content 0.2%, fugitive constituent is 12%, ash is not more than 0.5% refinery coke and places in the electric furnace, is finished product through 11 days behind the naturally cooling in heating under 2800 ℃ the temperature after 43 hours.
Embodiment 2:
With sulphur content 0.5%, fugitive constituent is 9%, ash is not more than 0.5% refinery coke and places in the electric furnace, is finished product through 13 days behind the naturally cooling in heating under 2600 ℃ the temperature after 38 hours.
Embodiment 3:
With sulphur content 0.3%, fugitive constituent is 10%, ash is not more than 0.5% refinery coke and places in the electric furnace, is finished product through 10 days behind the naturally cooling in heating under 2900 ℃ the temperature after 40 hours.
Claims (2)
1, a kind of high-power carburetant is characterized in that: it comprise sulphur content below 0.6%, fugitive constituent between 6-15%, ash is not more than 0.5% refinery coke.
2, according to the preparation method of the described high-power carburetant of claim 1, it is characterized in that: with sulphur content below 0.5%, fugitive constituent between 6-15%, ash is not more than 0.5% refinery coke and places in the electric furnace, be finished product through 10-14 days behind the naturally cooling in heating under 2500-3000 ℃ the temperature after 35-45 hour.
