Refractory powder flame projection moldings

摘要

Refractory moldings or repairing deposits formed by flame projection, composed of a solidified phase formed from fused fine refractory particles and nonfused coarse refractory particles dispersed in the solidified phase. The moldings or deposits have high thermal shock resistance and erosion resistance. They are produced by flame-projecting fine refractory particles and coarse refractory particles together into a mold or onto a substrate, e.g. onto a portion of a furnace to be repaired.
