[Title <strong>of</strong> the Invention]<br />
Hot metal desulfurization process and hot metal desulfurization agent<br />
[Claims]<br />
1. A process <strong>of</strong> hot metal desulfurization comprising calcium carbide powder in xx weight %<br />
<strong>of</strong> oil mixed in proportion <strong>of</strong> …kg/m 3 with a carrier gas and blown into the under side <strong>of</strong> the<br />
bath.<br />
2. A hot metal desulfurization agent comprising mixing <strong>of</strong> xx weight % <strong>of</strong> oil in calcium<br />
carbide powder.<br />
[Excerpt from Detail Description <strong>of</strong> the Invention]<br />
This invention concerns, in injection process desulfurization <strong>of</strong> hot metal, calcium<br />
carbide powder mixed with oil is used as desulfurization agent, thereby achieving efficiency in<br />
hot metal desulfurization process and desulfurization agent.<br />
Said oil can be gasoline, kerosene, vegetable oil, animal oil or waxes, and<br />
desulfurization agent, which includes one <strong>of</strong> the oils is blown into the <strong>for</strong>ge, the latter<br />
immediately turns into gas and destroys the particles <strong>of</strong> calcium carbide and disperses it,<br />
enlarging the area <strong>of</strong> contact with sulfur. Quick gassification, furthermore, improves the<br />
agitation in the bath, further improves desulfurization process. The oil also provides a better<br />
reducing environment in the bath, further improves efficiency <strong>of</strong> desulfurization.<br />
The proportion <strong>of</strong> calcium carbide powder to the oil is xx weight % <strong>for</strong> the reason <strong>of</strong>…<br />
In the said mixture, the calcium carbide powder digests the oil and manufactures<br />
calcium hydroxide on its surface, enhancing the motility <strong>of</strong> the powder, enabling a high<br />
proportion <strong>of</strong> calcium carbide to the carrier gas <strong>of</strong> …kg/m 3 to be carried by it, thereby reducing<br />
the amount <strong>of</strong> the carrier gas required in the process as well as a reduction in the amount <strong>of</strong><br />
calcium carbide powder, which also permits reduction in the temperature <strong>of</strong> the <strong>for</strong>ge.<br />
[Explanation]<br />
The related invention (Claim 2), hot metal desulfurization agent, is appropriate <strong>for</strong> the<br />
desulfurization. Even though it does not fall under the category <strong>of</strong> “equipment” being directly<br />
used in working the process <strong>of</strong> the specified invention (Claim 1), hot metal desulfurization<br />
process, it falls in the category <strong>of</strong> “other products” being directly used in working the process <strong>of</strong><br />
the specified invention.<br />
