Abstract: A cored wire for refining molten metal includes a reactive core material that is in the form of a solid rod. A non-reactive particulate material radially surrounds the solid core material, and an exterior metal jacket radially surrounds the particulate material. The particulate material may include wood or other material that when introduced into the molten metal, undergoes thermal decomposition to release carbon dioxide, hydrocarbons, or combinations thereof as a shroud around the core material.

Abstract: A consumable thermal torch for cutting through materials includes a first elongated generally cylindrical member adapted to receive an associated supply of oxygen into a first end and react with the oxygen at a second end. A second member has a hollow profiled similarly adapted to receive an associated supply of oxygen into a first end and react with the oxygen at a second end. The second member is received radially within the first member and is substantially axially coextensive therewith. At least one first gas flow passage is formed radially between the second member and the first member. At least one second gas flow passage is formed within the hollow profile of the second member and extends from the first end of the second member to the second end of the second member.

Abstract: The invention relates to a method for forming a corrosion-resistant coating on a ferrous substrate comprising: mixing the coating components in the powdered form with water until all of the powder is in suspension; coating the selected exposed surfaces of the ferrous substrate with the suspension; drying the ferrous substrate coated with the suspension to remove substantially all of the water; heating the coated substrate to an appropriate temperature and maintaining the coated substrate at this temperature for an amount of time sufficient for the formation of an alloy coating at the substrate-coating interface; cooling the coated substrate; and further to the coating produced according to this method.
