The present invention is a lance to blow a source gas into a container, comprising a nozzle unit provided with an internal space through which the source gas passes. The nozzle unit includes a nozzle wall provided with an internal space, a main nozzle penetrating the nozzle wall facing the container and communicating with the internal space to blow the source gas to the outside, and a sub nozzle penetrating through the nozzle wall to be positioned on an upper side of the main nozzle, communicating with the internal space, and extended to intersect a widthwise extension line passing through a center in a widthwise direction of the nozzle unit. According to an embodiment of the present invention, a contact ratio or opportunity with CO gas is increased by a swirl flow of a sub jet by the sub-nozzle; thereby a secondary combustion rate of CO being increased. Accordingly, it is possible to secure a sufficient heat source through secondary combustion without adding a separate heat source from ...

Принадлежит:

The present invention relates to a desulfurizer for molten iron, wherein a mixing material of the desulfurizer is manufactured by mixing quicklime, Al by-products generated during an Al dissolving process, and ladle slag. The desulfurizer for molten iron comprises: 80-85 wt% of the quicklime; 5-17 wt% of the Al by-products; 3-15 wt% of the ladle slag; and inevitable impurities. Therefore, desulfurizing efficiency of molten iron can be improved without fluorite which is an environmental pollution material. Moreover, as a material generated in a steel mill process is recycled for the Al by-products and the ladle slag, costs consumed for manufacturing the desulfurizer can be reduced.

The present invention relates to a lance and an operation method using the same. Since raw material gas is injected through a main channel of a lance onto molten metal inside a container and is injected through an auxiliary channel in which an extension line has an inclination angle of 10 to 40° with respect to a vertical axis orthogonal to a bath surface of the molten metal, the life of the nozzles and the secondary combustion efficiency of the molten metal can be increased. As such, the straightness and flowability of the raw material gas injected from the auxiliary channel are increased by providing a formation angle of the auxiliary channel capable of suppressing or preventing interference between the raw material gas injected from the main channel and the raw material gas injected from the auxiliary channel, and thus the problem of shortening the life of the nozzles due to backfiring of the raw material gas can be solved and the effect of increasing the secondary combustion efficiency ...
