Leadsun Refractory produce a comprehensive range of Fire clay brick consisting of 30-55% Alumina all of which exhibit excellent strength.For more arduous environments we offer a hand fired “super duty” Fire clay brick with a very high mechanical strength.
-
Excellent Refractoriness
Refractory clay bricks typically exhibit a refractoriness ranging between 1690℃ and 1770℃, enabling them to tolerate prolonged high-temperature conditions, making them well-suited for furnace linings in metallurgy, building materials, and related industries. -
Strong Thermal Shock Resistance
These bricks demonstrate outstanding thermal stability under high temperatures, effectively withstanding rapid temperature fluctuations and minimizing the risk of damage from thermal stress. -
Good Abrasion Resistance
They possess considerable resistance to wear, which makes them appropriate for lining equipment such as coke ovens and blast furnaces, where they can endure continuous abrasion and mechanical impact. -
Effective Slag Resistance
Refractory clay bricks offer reliable resistance to weakly acidic slags. Their slag corrosion resistance can be further improved by increasing the brick density when required. -
Notable Thermal Insulation and Fireproofing Properties
With favorable fireproofing and heat insulation capabilities, these bricks help reduce thermal energy loss, thereby enhancing the overall energy efficiency of high-temperature installations. -
Cost-Effective and Practical
Due to readily available raw materials and relatively low production costs, they represent an economical and widely adopted refractory solution. -
Eco-Friendly Nature
The manufacturing process of clay bricks has a limited environmental impact, and discarded bricks can often be recycled, supporting sustainable industrial practices.
