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.

ចរន្តកំដៅនៃវត្ថុធាតុ refractory: ចរន្តកំដៅបង្ហាញពីចរន្តកំដៅនៃសារធាតុមួយ។ ចរន្តកំដៅកាន់តែធំ ចំហាយកម្ដៅកាន់តែល្អ។ ដង់ស៊ីតេនៃឥដ្ឋដែលអាចជ្រាបចូលខ្យល់បានធំជាង ហើយចរន្តកំដៅគឺធំជាង។

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.

សីតុណ្ហភាពនៃការបន្ទន់បន្ទុកនៃសម្ភារៈ refractory: វាបង្ហាញពីភាពធន់នៃសម្ភារៈទៅនឹងសីតុណ្ហភាពខ្ពស់ និងការផ្ទុកក្នុងពេលតែមួយ។ ផលិតផល Refractory មានកម្លាំងបង្ហាប់ខ្ពស់នៅសីតុណ្ហភាពបន្ទប់ ប៉ុន្តែបន្ទាប់ពីផ្ទុកនៅសីតុណ្ហភាពខ្ពស់ ពួកវានឹងខូចទ្រង់ទ្រាយ និងកាត់បន្ថយកម្លាំងបង្ហាប់របស់វា។
