  As a refractory brick manufacturer, we have received many calls from customers. The first sentence is "How much does a refractory brick weigh? What is the weight of a refractory brick?" The weight of a firebrick is determined by its bulk density, while the weight of a ton of firebrick is determined by its bulk density and quantity.

  Refractory bricks are used in various high-temperature equipment, which are subjected to physical and chemical corrosion and mechanical damage under high-temperature conditions, so the performance of refractory materials should meet the following requirements:

  (1) High fire resistance

  The heating temperature of modern metallurgical and industrial kilns is generally between 1000-1800℃. Refractory bricks should be hard to melt under high temperature.

  (2) High-temperature structural strength
