The specific requirements for the application of refractory bricks are detailed below.
⑤ It can resist chemical corrosion of solution, dust and gas without deterioration and erosion. The refractory brick shall have good slag resistance.
⑥ It can resist the erosion, impact and abrasion of flame, furnace charge and material dust, and the surface will not be damaged. It is required that the refractory bricks have fairly high compactness and wear resistance at room temperature and high temperature.
⑦ It can withstand high-temperature vacuum operation and atmosphere change, without volatilization and damage. Firebricks are required to have low vapor pressure and high chemical stability. The appearance is neat, the dimension of refractory bricks are accurate, the quality is excellent and the price is low, and it is convenient for transportation, construction and maintenance.
⑨ For refractory bricks with special requirements, their thermal conductivity, electric conductivity and permeability should also be considered.
