A method for producing a component includes joining individual wall parts, especially for producing a melting crucible for use at a high operating temperature in a crucible-pulling method for quartz glass, wherein at least two wall parts of a refractory metal or of a base alloy of a refractory metal are provided, butt-joined to form a joint and joined together by sintering at a temperature above 1500 C. to form the component. A sealant is inserted into the joint to provide a component of improved tightness and to ensure improved sintering of the individual parts of the component. A component produced according to the method, particularly a melting crucible, particularly in a crucible pulling method for quartz glass, has the joint between the butt-joined walls closed in a gas-tight manner by a sealant.

Continuous flow submerged combustion melter cooling wall panels, including a primary metal plate, and several 90 degree metal pieces welded to the primary metal plate in parallel configuration, each of the 90 degree metal pieces having metal leg plates forming a 90 degree vertex there between. Each metal leg plate has an edge distal to the vertex, the distal edge of the first metal leg plate welded to the first major surface of the primary metal plate, the distal edge of the second metal leg plate welded to the vertex of an adjacent 90 degree metal piece. The plurality of 90 degree metal pieces may have a length (l) such that l<L, each welded to the primary metal plate in staggered configuration to form, along with first and second end plates and a seal plate, a serpentine continuous flow coolant channel.
