If a porous refractory with embedded refractories is used in a high-temperature atmosphere, the metal refractories will deteriorate due to oxidation or melt and deform. Although it was difficult to fully demonstrate its functions,
When the porous refractories of the present invention are embedded with plastic tubes, when dry, oxygen, a mixture of combustible gas and air, or air is passed through the plastic tubes to melt or burn the plastic tubes. The maximum safe operating temperature of the porous refractories produced by this process is determined by the refractory's own fire resistance, and it has become possible to use them at high temperatures without deteriorating their functionality.
