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.
Typically our firebrick range is based upon flint clay giving it both a low iron and low alkali characteristic.
Resistance to thermal shock,abrasion,chemical attack and reducing atmospheres are just some of the key
criteria determining choice of product within each application.a wide range of sizes are held in stock.
High Refractoriness
The refractoriness of refractory clay bricks is generally between 1690℃ and 1770℃. They can withstand high temperature environments and are suitable for furnace linings in metallurgy, building materials and other industries.
Good Thermal Stability
Clay bricks show excellent thermal stability at high temperatures, can resist changes in rapid cooling and heating, and reduce the risk of thermal shock damage.
Abrasion Resistance
Refractory clay bricks have high wear resistance and are suitable for linings of coke ovens, blast furnaces and other equipment, and can withstand long-term wear and impact.
Economical and Practical
Clay bricks have abundant raw materials, relatively low prices, and local materials, low production costs, and are an economical and practical refractory material.
Fireproof and Heat Insulation Properties
Refractory clay bricks have good fireproof properties and can effectively insulate, reduce heat loss and improve energy efficiency.
Slag Resistance
Clay bricks have strong resistance to weakly acidic slag, and in some cases their density can be increased to enhance slag resistance.
Environmentally Friendly
Clay bricks are relatively environmentally friendly during the production process, will not cause serious pollution, and waste can be recycled.
Multi-purpose
Refractory clay bricks can be used in various industrial furnaces, boilers, flues and other equipment that require high temperature resistance and wear resistance, and have a wide range of applications.
1.Carbon bake furnaces in the aluminium industry
2.Preheat zones and cyclones of rotary cement kilns
3.Insulation for glass tanks
4.Coke ovens
5.Blast furnaces
6.Reheating furnaces
7.Suspended roofs
8.Lime kilns
