Thermic lance head for cutting metal or concrete has coating consisting of ductile metal matrix with hard material particles embedded in it

The thermic lance head (9) has a number of outlet nozzles (16) to plow and oxidizer such as oxygen onto molten metal. At least in the part of the head most susceptible to wear, it has a coating applied to it. The coating consists of a ductile metal matrix, in which hard material particles are embedd...

Beschreibung
Zusammenfassung:	The thermic lance head (9) has a number of outlet nozzles (16) to plow and oxidizer such as oxygen onto molten metal. At least in the part of the head most susceptible to wear, it has a coating applied to it. The coating consists of a ductile metal matrix, in which hard material particles are embedded. The part of the head most susceptible to wear is the front region facing towards the molten metal, including the edges (17) of the outlet nozzles, which may be in a nozzle head (15). Es werden ein Lanzenkopf (9) mit einer Anzahl von Austrittsdüsen (16) zum Aufblasen eines Oxidationsmittels, insbesondere von Sauerstoff (10), auf ein Metallbad sowie ein Verfahren zur Herstellung eines Lanzenkopfes (9) angegeben, wobei zumindest in einem einer Verschleißgefahr ausgesetzten Teilbereich eine Beschichtung aus einer duktilen metallischen Matrix mit eingelagerten Hartstoffpartikeln aufgebracht wird. Hierdurch wird die Standzeit des Lanzenkopfes (9) erhöht.
