就拿 透氣磚 舉個例子，簡單介紹一下耐火材料的基礎知識

For steel manufacturers and refractory materials industry, breathable bricks are very important and common refractory products; taking breathable bricks as an example, this article discusses the refractory materials from the four aspects of thermal conductivity, specific heat capacity, refractoriness, and load softening temperature. Basic knowledge.

耐火材料的導熱係數：導熱係數表示物質的導熱係數。 導熱係數越大，導熱性能越好。 鋼包透氣磚的密度較大，導熱係數相應較大。

Specific heat capacity of refractory materials: Specific heat capacity represents the heat absorption or heat dissipation capacity of an object. The larger the specific heat capacity, the stronger the corresponding heat absorption or heat dissipation capacity. The specific heat capacity of ventilated bricks is related to its baking and cooling time.

Refractoriness of refractory materials: As mentioned in the previous article, it is a technical indicator that integrates the chemical composition, dispersion, proportion and viscosity of the liquid phase contained in the material. Refractoriness is one of the important indicators of refractory materials. Refractory materials need to be able to withstand the high temperature of the use scene during use; for ventilating bricks, if the temperature of molten steel is too high, it will not only affect the life of the ventilating bricks, but even cause major leaks, etc. accident.

耐火材料的荷重軟化溫度：表示材料同時承受高溫和荷重的能力。 耐火製品在常溫下具有很高的抗壓強度，但在高溫下受壓後會變形，降低抗壓強度。
