Production manner of mat for surface burnup burner and mat null for surface burnup burner

摘要

PROBLEM TO BE SOLVED: To prevent back fire from occurring and enhance high temperature oxidation resistance even if thickness of plate is thin by guiding material metal from a lower side in a vicinity of a metallic circular disc having a protrusion protruding from a periphery thereof, melting the raw material metal to make thin metallic wire and randomly tangling, weaving into meshes, or simply laminating the metallic wire. ;SOLUTION: A raw material metal held in a tubular guiding member 12 is contained in a chamber 16, which is evacuated in order to the raw material metal and metal wire from being oxidized before gas is allowed to enter the chamber 16. A circular copper disk 11 is rotated at a constant velocity. The raw material metal (M) is pushed upward through the tubular guiding member 12 by an upwardly pushing member 14 and an distal end portion is heated and melted by a high frequency induction coil 13. The molten distal end portion of the raw material metal (M) is made to get into contact with a periphery of the circular copper disk 11 which is being rotated to form thin metallic wire 5. As the distal end portion of the raw material metal (M) is consumed, an actuator 18 effects control so as to keep state of contact of the material metal (M) with the circular copper disk 11 constant. Heat radiation effect is enhanced and effect of preventing back fire from occurring is also enhanced. High temperature oxidation resistance is also enhanced.;COPYRIGHT: (C)1997,JPO
