ABSTRACT:
In direct pouring of molten metal for an ingot-making process, hollow long bodies made from self-fluxing heat-resistant sheets are used as a splash-preventive pipe. The self-fluxing heat-resistant sheet is composed of one or more inorganic fibers having fixed softening and fusion temperatures, binders and silicate fillers. The fusion rate and temperature of the sheet are selected in accordance with the teeming rate and temperature to insure that the body end is fused and consumed while being submerged in a given depth below the molten metal surface in a mold.
