Abstract: A three dimensional flame nozzle on which at least four conduits stand upright. Each conduit has at least upper and lower nozzle tips. The angles of each nozzle tip can be adjusted so that a flame blown from each nozzle tip intersects with the flame blown from a corresponding nozzle tip to form a three dimensional flame having a number-sign shape that is steady and focused near the central portion of reinforcement steel. A nozzle supporting fixture has a first hold fitting to firmly hold and release the reinforcing steel at one end of a nearly L-shaped nozzle supporting fixture and a second hold fitting to firmly hold and release a three-dimensional nozzle at the other end of the L-shaped nozzle supporting fixture.
