摘要： A flame spraying burner melts or partially melts with combustion heat, a spray material comprising a powdered fire-resisting material to thermally spray a damaged portion of a furnace wall or the like. The flame spraying burner includes a burner nozzle body having a central passage for supplying oxygen-contained gas, the central passage having a projecting leading end, and a plurality of fuel gas supply passages formed around the central passage. Each of the plurality of fuel gas supply passages has a leading end recessed from the leading end of the central passage. A cylindrical burner tile is positioned around the leading end of the fuel gas supply passages and extends to at least the leading end of the central passage. A plurality of oxygen jetting ports are formed in the radial direction around the leading end of the nozzle cap.

摘要： In continuous casting a thin carbon cast strip, the scale formed thereon is made thin and made to have a composition suited to working such as cold rolling and pressing. Moreover, an apparatus for inhibiting scale formation is simplified, and the consumption amount of an inert gas is reduced. The cast strip is thus produced efficiently. A carbon steel containing up to 0.5% of C is cooled and solidified by a pair of cooling drums to give a thin cast strip having a thickness up to 10 mm. The cast strip is introduced into a seal chamber, where the strip is held in an Ar gas atmosphere containing up to 5% of oxygen through a temperature region to at least 1,200.degree. C., and the strip is cooled at a rate of at least 10.degree. C./sec through a temperature region to 750.degree. to 800.degree. C., followed by coiling the strip in a coil form with a coiler at a temperature of at least 500.degree. C. and up to 800.degree. C. Furthermore, the atmosphere is formed with a nitrogen gas or exhaust gas. The scale formation is inhibited, and the composition of the scale is controlled by the use of the atmosphere.
