By Anderson Refractory clay fire bricks of this kind are vital in industry.
I. Properties
High Refractoriness: These bricks can bear temperatures above 1500°C without getting deformed. Their composition and firing process lead to a stable microstructure. For example, in a steelmaking furnace, the molten steel constantly subjects the bricks to intense heat. Still, the bricks keep their shape and integrity, which ensures the steelmaking process goes smoothly.
Good Thermal Insulation: With low thermal conductivity, they cut heat transfer, enhancing energy efficiency and safeguarding equipment shells. In a glass melting furnace, these bricks help to keep the heat inside the furnace, reducing the amount of energy required to maintain the high temperatures needed for glass production.
Chemical Resistance: Resistant to chemical corrosion in harsh industrial atmospheres. In a chemical processing kiln where various reactive substances are present, the bricks withstand the chemical attacks and prevent contamination of the products being processed.
II. Applications
Furnaces: Used in melting and heat-treatment furnaces for metals.In an aluminum smelting furnace, refractory clay fire bricks line the inside. They create a stable, high-temp space for melting aluminum ores. In steel heat-treatment furnaces too, these bricks are useful. Here, exact temperature control and stable structure are key for getting the right steel properties.
Kilns: Essential in ceramic and cement kilns. In a porcelain kiln, the bricks ensure even heat spread and fire the porcelain evenly, making it gain hardness and gloss. In a cement rotary kiln, they bear high temps and the corrosive setting from raw materials and reactions during cement making.
Boilers: Protect boiler walls from intense heat and boost thermal efficiency. In a large industrial power plant boiler, the refractory bricks act as a thermal barrier, reducing heat loss to the surroundings and increasing the overall efficiency of the power generation process.
