What is the refractory mechanism of refractory materials? !

Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580°C. Refractoriness refers to the Celsius temperature at which a conical sample of refractory material can resist the effects of high temperatures without softening or melting, in the absence of any load. However, defining refractory materials solely based on refractoriness is no longer sufficient to describe them fully; 1580°C is not an absolute value. Materials whose physicochemical properties permit their use in high-temperature environments are now defined as refractory materials.

Refractory materials don’t burn easily, hahahahaha. What a strange question...

Mechanism: it contains no C or very little, so it cannot reach the ignition point; it is non-flammable and lacks an oxidizing agent. . .

Then why isn’t that steel heat-resistant? It can’t even reach its ignition point.

The principles of fire prevention can be summarized in the following five points: (1) Fire-resistant coatings are inherently flame-retardant or non-flammable, preventing the protected substrate from coming into direct contact with air, thereby delaying the onset of combustion and reducing its speed. ⑵In addition to being flame-retardant or non-flammable, fireproof coatings also have a low thermal conductivity, which helps to delay the transfer of flame temperature to the substrate being protected. ⑶Fireproof coatings decompose when heated to release non-flammable, inert gases, which dilute the flammable gases produced by the heating of the object being protected, thereby making it harder for those gases to catch fire or slowing down their combustion rate. ⑷Nitrogen-containing fire-retardant coatings decompose when heated, releasing groups such as NO and NH3, which combine with organic free radicals to interrupt the chain reaction and reduce the temperature. ⑸Expansive fireproof coatings expand and foam when heated, forming a carbonaceous foam insulation layer that encloses the object to be protected, delaying the transfer of heat to the substrate and preventing the object from catching fire or experiencing a decrease in strength due to rising temperatures.

Umm, creep... Sister, I was wrong

Refractory materials, not fireproof coatings.
