Abstract
An improved apparatus for EAF steelmaking providing a lance for the injection of oxidizing gas, preferably oxygen, or other metallurgical gases and particulate materials into a steelmaking process. In one embodiment, the apparatus comprises a lance body configuration which has a central conduit for the supply of a pressurized flow of oxygen. A consumable lance tip made of refractory material is connected to the lance body such that it is in fluid communication with the central conduit.
Claims19
An apparatus for the introduction of gases, particulate materials entrained in a carrier gas, and or combinations thereof into a metal melting, processing or refining process, said apparatus comprising:
- a reusable body having at least one supply conduit for carrying the gases, particulate materials entrained in a carrier gas, and or combinations thereof;
- and
- a consumable tip coupled to the reusable body and having at least one introduction conduit in communication with said at least one supply conduit for introducing the gases, particulate materials entrained in a carrier gas, and or combinations thereof.
An apparatus for the introduction of gases, particulate materials entrained in a carrier gas, and or combinations thereof into a metal melting, processing or refining process, said apparatus comprising:
- a reusable body made at least partially of a thermally conductive material and having at least one supply conduit for carrying the gases, particulate materials entrained in a carrier gas, and or combinations thereof;
- and
- a consumable tip made at least partially of a thermally resistive material, coupled to the reusable body and having at least one introduction conduit in communication with said at least one supply conduit for introducing the gases, particulate materials entrained in a carrier gas, and or combinations thereof.
An apparatus for the introduction of gases, particulate materials entrained in a carrier gas, and or combinations thereof into a metal melting, processing or refining process, said apparatus comprising:
- a reusable body made at least partially of a thermally conductive material and having a plurality of supply conduits for carrying the gases, particulate materials entrained in a carrier gas, and or combinations thereof;
- and
- a consumable tip made at least partially of a thermally resistive material, coupled to the reusable body and having a plurality of introduction conduits in communication with said supply conduits for introducing the gases, particulate materials entrained in a carrier gas, and or combinations thereof.
