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.

ການນໍາຄວາມຮ້ອນຂອງວັດສະດຸ refractory: ການນໍາຄວາມຮ້ອນຊີ້ໃຫ້ເຫັນເຖິງການນໍາຄວາມຮ້ອນຂອງສານ. ການ conductivity ຄວາມຮ້ອນຫຼາຍ, ການ conductor ຄວາມຮ້ອນທີ່ດີກວ່າ. ຄວາມໜາແໜ້ນຂອງດິນຈີ່ທີ່ລະບາຍອາກາດໄດ້ມີຂະໜາດໃຫຍ່ກວ່າ, ແລະການນຳຄວາມຮ້ອນມີຂະໜາດໃຫຍ່ກວ່າ.

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.

ອຸນຫະພູມການໂຫຼດ softening ຂອງວັດສະດຸ refractory: ມັນຊີ້ໃຫ້ເຫັນຄວາມຕ້ານທານຂອງວັດສະດຸກັບອຸນຫະພູມສູງແລະການໂຫຼດໃນເວລາດຽວກັນ. ຜະລິດຕະພັນ refractory ມີຄວາມເຂັ້ມແຂງ compressive ສູງຢູ່ໃນອຸນຫະພູມຫ້ອງ, ແຕ່ຫຼັງຈາກໄດ້ຖືກ loaded ຢູ່ໃນອຸນຫະພູມສູງ, ພວກເຂົາເຈົ້າຈະ deform ແລະຫຼຸດຜ່ອນການບີບອັດຂອງເຂົາເຈົ້າ.
