Take the breathable brick as an example, briefly describe the basic knowledge of refractory materials

Qabul qiling nafas oladigan g’isht misol sifatida, o’tga chidamli materiallarning asosiy bilimlarini qisqacha tasvirlab bering

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.

(Rasm) O’tga chidamli

Olovga chidamli materiallarning issiqlik o’tkazuvchanligi: Issiqlik o’tkazuvchanligi moddaning issiqlik o’tkazuvchanligini ko’rsatadi. Issiqlik o’tkazuvchanligi qanchalik katta bo’lsa, issiqlik o’tkazuvchanligi shunchalik yaxshi bo’ladi. Havo o’tkazuvchan g’ishtlarning zichligi kattaroqdir va issiqlik o’tkazuvchanligi mos ravishda kattaroqdir.

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.

Olovga chidamli materialning yuk yumshatish harorati: Bu materialning bir vaqtning o’zida yuqori harorat va yukga chidamliligini ko’rsatadi. Olovga chidamli mahsulotlar xona haroratida yuqori bosim kuchiga ega, lekin yuqori haroratlarda yuklangandan so’ng, ular deformatsiyalanadi va bosim kuchini kamaytiradi.
