This means that if it is less than (+) 5% by weight, even if the hot spray repair material reaches the repaired part of the molten metal processing container, it will not harden sufficiently, and it will eventually fall without adhering to the repaired part. (ii) 10
This is because if it exceeds % by weight, the hot spray repair material will harden before reaching the repaired part of the molten metal processing container and will fall without being attached to the repaired part.

能している。Fireclay powder is FL for hot spray repair materials! It helps the hot spray repair material adhere to the repaired part of the molten metal processing container by controlling the IJ property, and after adhering to the repaired part of the molten metal processing container, the hot spray repair material is cured and the hot sprayed repair material is attached to the repaired part of the molten metal processing container. Powder of at least one of sepinite, bentonite, magnesium silicate, kaolin, humic silica, etc. is suitable. Fire-resistant viscosity 1=The powder is preferably used in an amount of 1 to 10% by weight of the total weight of the hot spray repair material (excluding the weight of the organic solvent). This is (i)l! l! ! This is because the hot-sprayed repair material cannot be sufficiently cured, and even if it adheres to the repaired part of the molten metal processing container, it cannot be stably bonded and falls off, and (ii) 10% by weight
This is because if the hot spray repair material is exceeded, the hot spray repair material will rapidly harden before reaching the repaired part of the molten metal processing container and will not be able to adhere sufficiently to the repaired part. The fireclay powder also functions as a sintering aid when it is bonded to the repair part of the molten metal processing vessel and then sintered by the hot spray repair material or the high temperature environment of the molten metal processing vessel.

硬化性樹脂粉末を多量に付着してしまうためである。Organic solvents are used to sufficiently and reliably adhere thermoplastic resin powders and thermosetting resin powders to refractory aggregate powders, such as ethylene glycol, polyethylene glycol, methanol, or low-viscosity novolak-type phenolic resins. It is preferable if it says. The organic solvent is preferably blended in an amount of 0.5 to 1.5% by weight of the total weight of the hot spray repair material (excluding the weight of the organic solvent). This is because (i) if it is less than 0.5% by weight, the thermoplastic resin powder and thermosetting resin powder cannot be sufficiently adhered to the refractory aggregate powder, and (ii) if it exceeds 1.5% by weight. This is because a large amount of thermoplastic resin powder and thermosetting resin powder adheres to the refractory aggregate powder.

て、本来の性能を失うことがない。The hot spray repair material is pumped by pressurized air toward the repair portion of the molten metal processing vessel. Once inside the molten metal processing vessel, the hot spray repair material is exposed to a high temperature environment and heated. As a result, the thermoplastic resin, thermosetting resin, and fireclay gradually become fluid, and at the same time, the thermosetting resin gradually begins to harden. At this time, the thermoplastic resin and thermosetting resin are prevented from oxidizing by the action of the metal powder, so that they do not lose their original performance.
