Product Details
Mullite Refractory Brick for Sale
Mullite bricks are a kind of high-alumina refractory material, mainly made of mullite as the main crystalline phase.Fireramo’s Mullite Series refractory bricks have an alumina content of between 65% and 75%. Mullite bricks have a high refractoriness of more than 1790 °C.
High-performance mullite bricks are a high-quality refractory material that can be categorized into sintered mullite bricks and electrofused mullite bricks. Mullite bricks are widely used in industrial fields due to their unique physical properties and chemical stability.
Fireramo, as a leading refractory brick manufacturer in China, manufactures our mullite bricks in strict accordance with national standards and undergoes fine processing and strict quality control to ensure that each brick has excellent performance and stability.
Characteristics of Fireramo mullite bricks
High alumina content: the alumina content of mullite bricks is up to 60% or more, and with the upgrading of the model, the alumina content increases gradually, making the mullite bricks have excellent high temperature resistance.
Low impurity content: Fireramo strictly controls the content of iron oxides and titanium oxides to ensure the purity of the product and reduce the impact of impurities on the product’s performance.
Excellent physical properties: Mullite bricks are characterized by high density and low porosity, which gives them better compressive strength and wear resistance.
Good thermal stability: in a high-temperature environment, mullite bricks can maintain stable physical and chemical properties and are not easy to deform or crack.
Outstanding thermal shock resistance: after many cycles of hot and cold tests, Fireramo’s mullite tiles remain intact and are not easily damaged, with good thermal shock resistance.
Applications of Fireramo mullite bricks
High-performance mullite bricks are widely used in metallurgy, ceramics, glass, the chemical industry, and other high-temperature industrial fields, as the lining material of furnaces and thermal equipment, which can withstand high temperatures and chemical erosion to ensure the long-term and stable operation of the equipment. In addition, mullite bricks can also be used to make high-temperature furnaces, refractory pipes, etc., to provide reliable refractory protection for industrial production.
Common applications of mullite bricks
Hot blast furnace roof
Blast furnace body and bottom
Glass kiln heat storage chamber
Ceramic sintering kilns
Dead-end linings for oil cracking systems
Production process of Fireramo mullite bricks
Ingredients: high-bauxite clinker, industrial alumina, and kaolin are used as raw materials.
Forming and drying: High-frequency vibration pressurization is used to form the bricks with dimensions of 230 x 114 x 65 mm, after which they are dried.
Firing: Firing in a domestic 24M heavy oil tunnel kiln, temperature control at 1400±10℃, firing cycle is 24 hours.
